What is better - hydraulic tape or electric power steering? Pros and cons of GUR and EUR. Steering over the wind: comparing steering amplifiers What power steering is better than hydro or electric

The modern driver is difficult to imagine that a few more decades ago vehicles have not been equipped with steering amplifiers. This equipment began to massively establish cars Only in 1952. Today, two types of systems that reduce the control force are most popular: hydraulic lines (GUR) and electric power plants (EUR), but few people know what the electric power steering power is different.

Gur and Eur perform the same tasks, namely:

• make the process of controlling the vehicle easy and comfortable,
• reduce the strength of the blows that are transmitted to the steering wheel in the process of driving in a bad road surface,
• raise level active security cars.

How Gur.

Gur is a complex and well-thought out mechanism. In order to understand the principle of his work, you need to understand the following questions: what elements are included in its composition and how they work.

• Pump connected to a tank for oil. His task is to create and maintain a certain pressure in the system.
• The regulator (distributor) of pressure forcing the oil to act in one or another department of the power hydraulic cylinder.
• Power hydraulic cylinder rotating piston rod under the action of oil pressure.
• Oil highways, according to which the liquid circulates continuously.

All the time, while the vehicle rides on a straight road, the hydraulic fluid is in the tank, which is connected to the pump. After the driver begins to rotate the steering wheel, the pump pumps the fluid into the hydraulic cylinder, which under the action of increasing pressure moves the piston, significantly reducing the magnitude of the force required for the rotation of the steering wheel.

How EURE works

For the operation of the electric poweror, it is necessary for the well-coordinated interaction of a number of mechanisms operating under the control of the ECU and two measuring transducers (sensors), fixing the angles of turns and the magnitude of the engine torque. During the rotation of the steering wheel, information on the magnitude of the torque is fixed and processed by the sensor that sends it to the electronic control unit. In turn, the ECU, based on the data obtained, calculates the current value to be supplied to the electric motor to ensure the lung and comfortable rotation of the steering wheel.

Pros and cons of electrical and hydraulic steering amplifiers

Positive qualities GUR.The main advantage of hydraulic steering amplifiers is their relatively low cost. It is thanks to this factor that the mechanisms are most often equipped with inexpensive budget cars.

Hydraulic amplifiers are characterized by a good power supply. It is advisable to install on off-road cars and minibuses, because These devices are able to well withstand a long exposure to high external loads.

Negative qualities of GUR.Vehicle owners on which a hydraulic amplifier is installed must be remembered that the steering wheel should not remain in the extreme right or extreme left position longer than 4-5 seconds. Exceeding this time limit may cause overheating of the system of the system with further output of its failure.

Experts argue that GUR must be periodically servicing. Replacing fluid circulating in the system should be carried out regularly. It is also necessary to inspect the surfaces of all components of its elements. If in the process of their visual inspection, cracks or traces of fluid leakage will be detected, then it is necessary to immediately replace the part for a new spare part.

Hydraulic steering amplifier during its work necessarily takes a certain percentage of power from the engine.

With an increase in the speed of the ride, the speed of the GUR response to the actions of the driver's driver is reduced. This is explained by the presence of additional nodes that slow down the reaction of the device to rotate the steering wheel.

Positive qualities of EUR.A simple and efficient design of the electrical steering amplifier is devoid of any additional nodes. Periodic maintenance EUR does not require temporary and material costs. It comes down only to verification of rolling bearings.

Little dimensions are distinctive feature Electrocessor. Thanks to the modest sizes, its installation is carried out directly on the steering shaft, and not in podcast space cars. Such a location avoids the negative impact of weather factors on the efficiency of EUR, thereby significantly increase its life.

The presence in the electric power steering car guarantees substantial savings fuel mixes. Gasoline is spent less because EUR is included only during the turns of the steering wheel, unlike the GUR, which works continuously throughout the trip. In this case, the electromechanical system does not select the percentage of power at the motor. Food from on-board network vehicle.

The steering wheel in the car with EUR can be in the extreme position an unlimited amount of time.

While driving at high speeds, the car with an electronic steering amplifier is well listened to the driver, therefore always remains maneuverable. At the same time, the ride process becomes more secure.

Negative qualities of EUR.The most significant disadvantage of the electric powerful is its high price.

The second minus is that the electric motor of the electromechanical system has a slight supply of power. For this reason, EUR is not yet installed on heavy vehicles, but the manufacturers of the device claim that in the very near future this deficiency will be eliminated.

December 2, 2016.

It is now difficult to imagine a car whose Baranka is stronger with difficulty, as it was in former times. Driver controls modern car A slight movement of hands, since the wheels turn the special amplifier, driven by hydraulics (GUR) or by the electric motor (EUR). It is important to understand the potential car enthusiaeer to understand that better - electrical or hydraulic steering wheel, in order to choose the appropriate type of drive when buying a car.

Principle of operation of the GUR and EUR

The hydraulic steering wheel amplifier appeared last century and at first installed on trucks. In the 80s, he twisted on the passenger cars, where faith and the truth serves to this day. At the moment, the hydraulics is equipped with approximately 60% of new cars.. Electric powerors were introduced later and became massively applied after 2000, gradually winning the automotive market.

To see the difference of one steering steering from the other, you need to consider the principle of action of both mechanisms. Gur is a rather complicated node consisting of several separate elements:

• a pump bound with a belt transmission with a crankshaft engine;
• expansion tank for hydraulic fluid;
• piston installed in the steering rake;
• hydro-distributor specifying the direction of movement of the piston.

The listed elements are connected by metal tubes with circulating fluid. Her task - at the right moment, transfer the piston pressure created by the pump, pushing the rail shaft and in such a way to help rotate the wheels of the machine. In general, GUR works like this:

1. After starting the engine, the pump rotated by the crankshaft pumped pressure in the system. While you do not touch the ram, surplus the pressure is reset into the expansion tank.
2. When trying to turn the steering wheel, the distributor mounted on its shaft opens the desired highway and directs the liquid into one of the chambers in the right or left side of the piston.
3. Under pressure, the piston moves and pushes the shaft of the steering rack simultaneously with the burden attached to swivel fist. front wheel.
4. If the Branca turn into the other direction, the distributor will block the first highway and open the second, the pressure will arise in another chamber and the piston moves in the opposite direction.

The sharper and stronger you rotate the steering wheel, the greater the pressure is transmitted to one of the chambers and the force attached to the rotation of the wheels is increasing. The system responds only to turn the main shaft, and when moving in a direct or parking lot with a running engine, it continues to work, but it does not work on the rail.

The difference between the electric power amplifier from the GUR is to move the rack shaft by the electric motor managed by a separate electronic block (ECU). The algorithm of work is:

1. After starting the engine on the control unit, the voltage is supplied, but EUR remains inaction.
2. The slightest twist of the ram captures a special sensor transmitting the pulse of the ECU.
3. According to the sensor signal, the controller gives the command to the electric motor to rotate the steering shaft in one direction or another by means of a gear transmission.

The speed of rotation of the motor shaft and the gain power is determined by the second torsion sensor twisting with a sharp turn of the steering wheel.

Pros and cons of different amplifiers

The use of hydraulics to facilitate the control of the car is due to the following advantages of the Gora:

• lower production cost influencing the final price of the new machine;
• from the hydraulic agent, it is possible to obtain greater power, allowing it to be used in trucks and minibuses of any carrying capacity;
• reliable design, tested for years of operation.

Main flaw hydraulic system - the need to control the level of fluid and periodic maintenance. It is necessary to monitor so that the glands of the piston mechanism, the distributor and the pump, to change and pull the belt on time, lubricate the bearings.

Other minuses are not so significant:

1. The amplifier pump runs constantly while the engine is turned on. This increases fuel consumption.
2. So that the oil pressure in the highways does not exceed the critical mark, it is impossible for longer than 5 seconds to hold the ramp, rotated to the extreme position.
3. On budget models of machines, the steering wheel enhanced by GUR becomes "empty" at high speed.

As opposed to Hydraulics, EUR has such advantages:

• the electric motor and control unit with the sensor does not need inspections and maintenance;
• the dimensions of the node are much smaller, which is why it is in small chairs at the dashboard;
• the system does not consume electricity without need, which means it does not consume unnecessary fuel;
• the steering wheel can be kept in any position how long.

Another feature of the electric power steering is the ability to change the settings of the work depending on the driving conditions and the artificial creation of "gravity" in the ram at high speed. In addition, EUR can "steer" by the machine independently when moving in a straight line, which is implemented on many premium cars.

Weak side of the electric amplifier - high price. And the more the cost of the node, the more expensive it will cost, and often the emerging eur has to change the whole.

The second drawback - small power Drive, so such amplifiers are not put on heavy trucks and minibuses.

What amplifier to choose?

Practice shows that both drives are quite reliable in operation, although supporters of electrical amplifiers argue the opposite. Even in budget cars, the hydraulics serves without problems 100-150 thousand km, and in the case of some breakdown, it is repaired on any car service. EUR faults often lead to replacement of the mechanism, because in most cars the node is not subject to recovery.

On the other hand, the electric drive does not interfere with the ride after the failure of how it makes the GUR, which can be "neutralized" only by disconnecting the pump.

Therefore, choosing a hydraulic tape or electric power steering, guided by considerations of expediency. For example, the economy class machine is better to buy with a hydraulic amplifier, and the business and premium class - with electric.

Owners of domestic auto celebrate cases when an electric amplifier because of the electronics failures tried to "steer" instead of the driver, although such moments are extremely rare. However, EUR is constantly improving and displaces the hydraulics from the market due to a more successful and simple design.

Electric power steering or simply eur comes to replace your common opponent, namely the hydraulic plot (GUR). This is facilitated by the development of technology, the development of electronics, as well as the installation of improved driver assistance systems (for example - automatic parking). Also, the electric fellow allows slightly saving fuel. Now there are at least 4 main designs of this type. BUT! Many producers are in no hurry to move with "Hydro" to "Electro". But why? It is so ideal, as it works - the EUR is arranged, as it should be operated, so as not to soak. About it today and talk to you, as usual will be a video version. So we read look ...

For a start, a small definition.

EUR (electric power steering) - an electromechanical system that reduces the control force that is applied to the steering wheel.

At the very beginning I want to say that this article will not be about comparing such an article I already have (although some moments will still slip).

About Egur

One more helpful information And again at the beginning of the article, many confuse an electric amplifier with the so-called egur - electric power steering. But it is extremely wrong. Egur is just an improved hydraulic amplifier the only difference in that - the usual GUR uses belt transmission from crankshaft the engine that spins the pump for pumping pressure in the system, that is mechanical transmission. Egur does not have such a program, he does not associate with the crankshaft at all, it has simply electrical engine From above, powered by onboard system and cattures pressure.

In essence, the belt and the mechanical pump, replaced with wires and electric pump, hence the prefix "e" - electric.

How does the electric power steering

There is no oil, nor any other liquid, in fact, this is an ordinary steering rail (without an amplifier at all) to which the electric motor is installed on this or that shaft, which performs the role of the amplifier. Distinguish designs:

• When it is installed on the steering shaft, that is, put in the car's cabin and enhances the driver's shaft, straight from the steering wheel
• When the engine is installed on the rack shaft and strengthens it

Basic parts (the rack itself and the steering shaft I will not take, about them everything is clear)

• Electric motor. Modern brushless
• Servo. Also varies by type, about it just below
• Torque sensor. The main sensor system is usually installed on the torsion, which is placed in the incision of the steering shaft. At the ends of Torsion there are two different parts of the sensor. It can be both optical and magnetic.
• Power rotation sensor
• Control block
• Optional - can be installed a steering speed sensor

When the steering wheel turns, the torsion starts to spin, the more turn the steering wheel, the more it is spinning. By changing parts of the position of the sensor, the laid force is estimated.

Another measurement occurs by the rotation sensor, he "sees" how the steering wheel dismissed. Both of these readings are sent to the EUR control unit, and it is already interacting with. Also, the ECU receives such important parameters:

• Car speed, from ABS sensors
• Engine turnover from engine sensor

After that, on the basis of all data, the ECU calculates the necessary effort (help) on the steering wheel, and delivers the power to the electric motor of the desired polarity and the value. The actual electrical engine starts to rotate either the steering shaft, or move the shaft of the rack itself.

Main types of eura design

• Built in the steering shaft (column). If we consider the rack itself, then this is an ordinary steering rail, without any changes. The engine itself is located in the cabin and is located on the shaft built-in in steering columnThis is the cheapest design of all electrical types. Therefore, it is so massively installed on the budget models of cars, including many VAZ. Of the positive moments, not only the price, and the simple design of the rail, but also the fact that the electrical part is in the cabin, which means it is less susceptible to temperature drops and moisture (snow) from under the wheels, that is, the vitality is increased. The minuses can be called that the system is supplied with a worm compound, friction losses increase due to this, the informativeness of the steering wheel drops. That is, inertia + friction, it is impossible to set up sensors! It "striking", especially those drivers who have moved from Gora.

Positive moments and opportunities

Pluses the electric power steering is quite a lot, it seems to me, soon almost all manufacturers will switch to such a type, refusing completely from the hydraulics. And now items:

• Efficiency. The electrical amplifier saves from 0.5 to 0.8 liters per 100 km of way. It is not associated with the engine with a rigid strap, and therefore it does not take power from it, and consumes only when necessary. For example, on idling It does not work at all, while GUR is constantly connected in the crankshaft.
• Reliability. Here it is higher, especially if the electric motor is located in the car's cabin. There are no hoses, no liquids, nor other parts.
• Service. It is practically not necessary here! No need to change through a certain mileage to restore performance.
• Silence of work. If the Gur grabbing air, then with Erena, it is unlikely to happen. Yes, and the good node works much quieter.
• The cost of the node. If we take in general, especially the first type, then it is lower than that of the hydraulic fellow, however, the repair is often much higher, because the sensors or elements are changed.
• Programmable work. If the gur you can simply disable, then with EUR, it can easily occur, and this can be programmed. For example, at low speeds, we need a lot of effort on the steering wheel, but with a speed set, we do not need a lot of effort, in fact the steering wheel is well controlled. Here, the electrically amplifier can be turned off and the electrically amplifier can be turned off, again saving fuel. Yes, and in many cars there are coppe forced shutdownThis is again plus.

If you take the opportunities that it gives, they are almost limitless. Such systems are already working as a car stabilization with a sharp detachment of obstacles, hold in the strip, parking assistance. It should be noted that EUR is a step towards automatically manned machines.

Negative moments

They also have and in principle, I listed them in this article, but now I repeat a little:

• Candying informativeness of the steering wheel (hydraulics, is currently more accurate)
• Electrical failures in the settings. Can go a sensor (steering or shaft) and for example, to unscrew the wheels in the side, then how to keep straight. Moreover, it is difficult to align the wheels.
• Failures in motion. In earlier versions there were accidents due to blocking or glitches eura
• Electrical component. As a rule, it is not repaired, and often changes, because your safety depends on it. That is, it is not worth "overparing" the power position sensor or shaft, because you can set incorrect parameters in the circuit. Better to change it. Also changing and fully the engine at the failure, which is not suiced.
• Do not always need repair. Often from a large run or from clogging, you just need to calibrate the sensors, you yourself do not make it again you need to go to a hundred. And if it is not pure into hand, you can take as for the repair.

The person is forced to make muscle efforts, overcoming the resistance of the wheels when the car turns. There is a need to apply the auxiliary device. His invention has become an important technical achievement that influenced the further development of the automotive industry.

In the 1920-1930s, the steering amplifiers tried to install on heavy dump trucks, armored vehicles. First, the devices were pneumatic (used air pressure). The low accuracy of such devices (with the increased weight and new speed characteristics of the technique) has opened the way the use of special hydraulic type amplifiers that have already been tested in shipping. Mass installation of hydraulic agents car steering Began in America in the 1940s, covered post-war Europe. (In the USSR many serial cars We were produced without an amplifier steering wheel.)

The border of the 20-21 centuries marked the beginning of the era of the introduction of electric power steering.

According to statistics, about 10% russian drivers Prefer the car that is not equipped with an amplifier of the steering wheel. For some of them, a monetary question is relevant (or these are the owners of small cars).

Someone loves the immediate feeling of the road, especially at high speeds, there are increased informativeness on complex coatings (ice, wet asphalt). There are motorists who like to make efforts. Most often it is a question of skill and habits.

Benefits of driving with an amplifier steering

• the amplifier takes the lion's share of load on itself;
• there is no need for a large number of rollers, it does not break out of the hands;
• soften the feeling of irregularities of the road;
• machine is easier to control, maneuverability increases; without effort, complex turns are managed;
• becomes more convenient taxiing at low speeds;
• stabilizes the trajectory of movement;
• when crossing the front tire it is easier to keep the car;
• the driver is less strained, not tired;
• especially relevant if the driver is a woman;
• the wear resistance of the steering mechanism increases, its service life is extended.

All this ensures the most secure and comfortable driving (subject to a serviceable operating machine).

Potential danger occurs only with a freelancer - a sudden refusal (breakdown) of the steering amplifier system when driving while driving. In this case, the response, knowledge and driver experience is crucial. Foreign noises, vibrations, harsh shocks, steering, hard or too light turning can be alarmed about problems.

According to statistics, a quarter of Russian drivers prefers a hydraulic agent, and half - the electric power steering (and the indicators are shifted in favor of the EUR). The advantages of each of these mechanisms are determined by their constructive features.

IN modern cars Electrical cylinders, hydraulic tapes and electric power steering are used.

EUR: What is it in the car (electromechanical steering amplifier, Emur, Euru)

EUR What is it in the car? Works like an electric motor. Affects steering by electrical drive.

Sensors analyze the position of the steering wheel. The readings are communicated to the electronic control unit, where they are processed by a special computer system. From here, the guidelines are transmitted placed in steering gear Electric motor. It converts electrical energy into mechanical, facilitating driving.

What is gur in the car (hydraulic power steering)

This device works by the type of pump. The effect on the power control mechanism is performed by fluid pressure (oil).

When the engine is turned on, the rotating drive belt enters the hydraulic pump. The constant supply of oil from the tank is maintained.

When the driver turns the steering wheel, the special mechanism (spool) moves, reacting to this rotation, and overlaps the oil drain channel back to the tank. The liquid through the distributor (valve) enters the power hydraulic cylinder.

It converts fluid pressure into the piston pressure, which produces a power effect on the steering. Upon completion of the rotation and straight movement, all channels are opening, the oil goes back to the tank and continues to circulate through the system by means of connecting hoses.

ElectrohydroSiller steering wheel (hybrid, electro-hydraulic power steering, egur)

There was an upgraded version of the hydraulicer. It works from a special generator (and not from the car engine) and turns off when the machine is moving along the straight trajectory.

Special sensors read the rotation speed. Signals are fed to the control unit and communicate the electrical motor, leading to the movement of the hydraulic pump.

Comparative characteristics

Disadvantages of the electric power steering and the advantages of the hydraulic agent:

1. There is a sensitivity of EUR to a bad (risky, bumpy) road and moisture (in particular, with bad weather - when snow, rain, puddles). In such cases, there is a risk of overheating and shutdown, as well as brave.
2. Gur better smoothes the shock at the irregularities of the road and the road to the border.
3. EUR does not give an instant reaction in the event of a quick turn of the wheels to the other side. And if you sharply twist the steering wheel, the system can turn off at all.
4. For GUR is more possibilities Independent repair.
5. In the case of EUR, the likelihood of electronics failure is not excluded (though, this is sin mainly old and cheap models; the other reason is non-compliance with the rules of operation).
6. Manufacturing GUR is less expensive; Their price is lower than the EUR.
7. EUR has a restriction on installing heavy trucks and SUVs (due to lack of power).

Benefits of the electric power steering

1. Ease of taxi with EUR ("one finger"). Excellent maneuverability when parking, fast adaptation to speed change.
2. Settings of EUR parameters with different modes of operation. (Stabilization with lateral wind, auto parking)
3. The latitude of the temperature range for the EUR. Liquid in Gur under the influence of temperatures and overloads can be frozen, boil.
4. Eases simplicity and maintenance. It is only necessary to monitor the state of bearings. Maintenance GUR is more laborious. Regular inspection for integrity, tightness tracking of hydraulic tubes, tension checking drive belt, oil level. There are rules for the replacement of oil and filter.
5. Compact sizes of EUR.
6. EUR economy (less fuel consumption, above efficiency).
7. Operation of the machine after disconnecting faulty EUR. For GUR it is undesirable (steering is destroyed; other breakdowns may occur).
8. The ability to hold the steering wheel in the extreme position at the EUR for a long time. On cars with GUR, delay over 5 seconds faces a serious breakdown.
9. ENVICE EUR. Cars with gur give more harmful emissions; It is more complicated by the Gur more complicated in disposal.
10. Serious prospects of the progress of EUR.

Choose between the hydro and electric power steering

Outcome

Some imperfections of the GUR are eliminated in models with Egur: an increase in the efficiency occurred, it became possible to set the necessary parameters, a drive belt was replaced with an electric motor. But the future is still behind electromechanical steering amplifiers. This is a global trend, because their advantages are obvious.

Automakers make everything to drive to the car delivered comfort and pleasure. This applies literally in the car, including the steering. The steering wheel should rotate easily, without effort, and not with difficulty, as it was in former times on old vehicles.

Currently, it is difficult to imagine a car without an amplifier of the steering wheel, that is, a special device that helps turn the wheel wheels. Many people know that such amplifiers are two types: hydraulic, that is, hydraulics (GUR), and electric operating with an electric traffic (EUR). Let's figure it out what the difference between the hydraulic tape or the electric power steering wheel?

Principle of work GUR.

Hydraulic steering column rotation amplifiers appeared in the last century and initially installed only on trucks. It's clear. It is much more complicated to control the multi-torque car than passenger. However, automakers with time began to apply GUR including on passenger carsThereby increasing their attractiveness compared to other brands. At the moment, the hydraulics is equipped with approximately 60% of new machines.

The power steering is a rather complex mechanism consisting of several elements:
- Pump associated with a belt transmission with a crankshaft engine;
- tank for hydraulic fluid;
- piston installed in the steering rake;
- Hydro-distributor specifying the direction of movement of the piston.

All these elements are combined with metal tubes, in which hydraulic fluid is located. Its task is to transmit pressure created by the pump, piston, which then pushes the rail shaft and in such a way it helps rotate the wheel of the machine. In general, Gur works as follows.

After the engine engine is launched, the pump rotated by the crankshaft is pumped up pressure in the system. While the driver does not rotate the steering wheel, surplus the pressure is reset into the expansion tank. When trying to rotate the car's beam, the distributor opens the desired highway and directs the liquid into one of the chambers in the right or left side of the piston.

Under pressure, the piston moves and pushes the shaft of the steering rack simultaneously with the burden attached to the twilty fist of the front wheel. Thus, the amount of effort is significantly reduced, which is necessary for the driver for rotation of the steering wheel.

If the steering wheel of the machine is turned to the other side, the distributor will block the first highway and open the second, the pressure will arise in another chamber and the piston moves in the opposite direction.

The principle of work EUR.

Electric power steering were introduced later than hydraulic, and they became massively applied only after 2000, gradually winning the automotive market of the world.

Both of these mechanisms perform the same function - facilitate car owner steering car. However, the difference between them lies in the fact that the EUR moves the rail shaft using a special electric motor, and the GUR using the pump and hydraulic fluid.

At the same time, the engine in the electrical steering amplifier is controlled by a separate electronic unit (ECU). The principle of work is as follows:

After starting the engine, the voltage is fed to the control unit, but the EUR is still not valid at this time. After the slightest turn of the steering wheel, this movement catches a special sensor that transmits the pulse of the ECU. According to the sensor signal, the controller gives the command to the electric motor to rotate the steering shaft in one direction or another by means of a gear transmission.

Pros and cons of the power steering

Gur has a number of advantages, thanks to which he at the time got widespread in the automotive market. Here are the most important:

- lower production cost, which in turn affects the final price of the new car;
- thanks to the use of GUR, it is possible to obtain a greater power, which is necessary during the operation of heavy trucks and minibuses;
- Reliable design of the hydraulic agent, which is checked for years of application.

Nevertheless, the GUR has and disadvantages. The main one is the need to control the level of fluid in the system and the frequency of maintenance. It is necessary to monitor so that the glands of the piston mechanism, the distributor and the pump, to change and pull the belt on time, lubricate the bearings.

Among other disadvantages, which are less significant, this is a slight increase in fuel consumption due to the fact that the hydroxidant pump works constantly while the engine is turned on.

Advantages and disadvantages of the electric power steering

In comparison with the GUR, the electric amplifier has several advantages:

- such a system, including an electric motor and a control unit with a sensor, do not need regular inspections and maintenance;
- smaller dimensions of the mechanism, that is, does not occupy a lot of space;
- EUR does not consume electricity without necessity and, it turns out, does not consume additional fuel.

The electric power steering also has other advantages, for example, concerning changes in the settings of its operation depending on the driving conditions. In addition, EUROs are used in modern premium cars, because it can be controlled by an on-board computer.

The main drawback of the electric amplifier is its high price. The more the cost of the mechanism and its elements, the more repairs will cost. Often the emerging EUR has to be completely changed. In addition, the electrical amplifier has less power, and this complicates its use for trucks and heavy vehicles.

What power steering is better?

Experience shows that both amplifiers are quite reliable in operation. Although the breakdowns occur and with the other. When choosing between GUR or EUR, it is necessary to consider each situation separately: what a driver, which is the driver and so on. Decide to you, and the characteristics of each are given above.

It should only be noted that the electric power steering is constantly being improved and displaced the hydraulics from the market due to a more modern and simple design. Perhaps over time, their cost will be reduced, and power will increase.
