It is worthwhile to dispel the myth about
That there is saving gasoline on the faith. When the accelerator pedal is released, in
The combustion chamber is sent by a small amount of fuel consistency, because special
There is no sense to go on a neutral transmission. Let's just say more
approval is burning not only for cars with automatic box Switch
Transmissions. On the modern cars with manual box when transferred to gearbox PPCs
Neutral economy position is not observed.
Saving gasoline on neutral
transmission takes place only on old cars with a carburetor, and with
The emergence of " electronic systems"In the motor, the statement of savings lost its own
meaning.
Hunt to note that with small
stops, for example, at the traffic light, switch the gearbox to the "neutral"
advise - it will only lead to excessive switching of the box itself that
Reduces its service life.
At the moment I would like to touch the device the box itself.
Carefully see
The operation of the automatic gearbox in neutral mode of operation.
Recall that in the box automatic power
From the motor is transmitted using a torque converter (specifically it is
own kind of clutch) on the input shaft of the box.
In order to form
different transmission numbersoften use planetary rows - this
The mechanism consisting of a certain amount of gears - satellites, which
spin around the central gear, with all this
All transfer cases will be achieved by fixing various
Details to each other.
Specifically switch itself
Transmissions (fixation of different parts) is performed by electrical or hydraulic
Control system. Automation continuously reads data from output shaft
Box automatic and motor, analyzing them chooses a suitable transmission.
The spectrum selection valve is connected by the selector lever Box machine, and it, on the basis of
The position of the lever does not give the ability to include certain gears.
Pressure is created by the oil pump
Oils in order to control the box automatic. Transmission fluid either
just oil as in the motor makes a list of functions including a function
Tire heat and lubrication.
What will happen
If we turn on the "neutral"? First you need to note
Subsequent moments: in order to
Move the gearbox automatic gearbox selector to neutral
position, the primary shaft of the automatic box is disconnected from the slave
(secondary) shaft.
Motor starts working in
mode idling (750-850 rpm), pressure in the lubrication system "machine"
It decreases in some places 2 times, in contrast to pressure in the ride mode.
On the
Neutral transmission can be moved at a speed of less than 40 km / h.
Therefore, as no tight break
Wheels and motor revolutions, torque from the wheel is transmitted to the slave shaft
gearbox shift, and if neutral transmission It was included on
The highest speed - the slave shaft will turn a substantially strong lead. IN
This moment the drive shaft of the motor and the gearbox conjugate with it, bearings,
The gears will be exposed to load speeds.
Due to the fact that in oil
The pressure system is set in the smallest, then at high speed on the slave
The "automaton" shaft and almost all the devices conjugate with it will arise and will increase
Oil starvation. As a result - local deformation, overheating of parts,
Reduced box operation time.
If you often
move at high speeds with the neutral transmission included, then the box
Soon fails.
Now it is necessary to determine what
Such "big speeds", and what they are not. To do this, look at
Annotation for the use of your car. In fact, in all such books
marked that towing the machine with a carton machine can be less than 40 km from
speed less than 40
km / h (from time to time this figure is reduced to 30 kmh). On some
Car models towing is completely prohibited.
This happens because
oil pressure pressure after 40 kmh will not be enough and not enough for lubrication
devices, and the box will become very hot. When the speed does not exceed 40 km / h - the pressure will also be small, the box will be
heated, but 40 km
All the same, it will be able to overcome without significant consequences. After that you need to give
Machine a few hours rest and continue to move again to 40 kmh.
As it should be on neutral
can still move (if there is no reversion to this
actions), but the speed should be no higher than 40 km / h.
What if
Switch the lever to the "Drive" mode
If the car driver with
Automatic gearbox goes specifically on the "neutral", early
Or late will need to be included "Drive". Here again you need to remember the difference
The speeds of the secondary and primary shaft of the gearbox box.
Mode
"Drive" perfectly turn on the car
Located in a static position.
Electric control box
Gears naturally will choose a suitable transmission that will correspond to
speeds (but no hope for electronics, because it can include and
1 transmission). Everyone who traveled on the machine know that the inclusion of the "Drive" regime on
worth the car causes a slightly tangible push - it is engaged in engagement
gears.
If the "Drive" mode after
Neutral regimes include on the car, which is in motion, in addition
that the moment of entry into engagement gear will be more significant, and
The load on the CAT due to the fact that it will need to coordinate the speed of rotation of the shafts.
Because "Drive" is better
Include all the same on the car.
Naturally, the unite translation of the lever changing modes on
the moving machine will hardly lead to great consequences, but if you often
"Play gears", then completely Misso, that output the box automatic (for
Fans are accepted. We recommend purchasing a machine with a mechanical gearbox).
Ultimately
hunt say:
- "Neutral" is not designed to become
Panacea in saving fuel. - On "neutral" you need to move
at speed below 40 km / h,
The greater the speed, the stronger the lack of oil and overheating of the checkpoint will come. - The mode "Drive" is the ideal
Include on the car which is in a static position (not either). - "Neutral" on the car with a carton machine is needed
Only for towing the machine (less than 40 km and with an indicated in an annoying
speed). For other purposes, we do not have a neutral transmission.
N - Neutral - Neutral Transmission. In this position of the selector, the car, as well as on "P", can be started, but the blocking of the shaft does not occur. However, it differs from the mode of neutral on hand boxes. In this mode, you can not roll under the slope or towing the machine with the engine off without risk to damage the machine. The fact is that the oil pump is on the primary automatic transmission shaft, so when the engine is turned off, it will not work, which means there will not be an ATF circulation and the box can overheat.* There is an opinion that, standing on the traffic light, go to "n", because in the "D" mode there is something there and wear out. In fact, it is not the case, all the elements of the box are immobilized, the frictions are clamped, the first transmission is turned on and only the pump is pumped. transmission fluid. The movement in this case begins without slipping the friction pairs, which come into operation only when moving to the second transmission. The transition from the mode "n" in "D", on the contrary, makes them once again Help.
In addition, the translating selector from the "N" mode in "D" should not immediately press gas, and it is necessary to wait for a characteristic push, which will show that the box entered the mode of movement and chose the necessary transmission, and in the heat of the hurry you can forget about it.
So it is not recommended to use the "N" mode, except for the restarting of the stuffed motor, as well as the towing of the car or rolling it manually with the engine turned off. At short stops, for example, on the traffic light, the selector should not be moved to the "N" position or to the "P" position, and hold the car in place in such cases with the help of brakes. If, with long stops in street traffic jams, you are tired of the leg, it is better to set the "P" mode. You can also enroll when stopping in hot weather, to reduce heat dissipation and prevent ATF overheating in the box.
* When moving on long descents, install the selector lever to the "n" position is not recommended. This will not lead to fuel economy, but can cause the box overheating when the D is returned at high speed.
So moving rolling the selector is better to leave in the position in which he was before. In this case, the box will switch to the highest of the allowed gear and provide minimal braking engine. If you rolled in "N" mode, the subsequent transition to "D" will make the box with the output mode, since it needs time to switch to the desired transmission. took from the old topic. Previously, the neutral neutral was also cut, until I did not read) it was written in that dawn something else and you can start it from the pusher. But I think it will not lead to anything good. In general, I advise you to travel as the Subaru plant consists in R D and 1 2 3 mode)
Drove up to the traffic light - transfer the selector to position n! Or in r! By this you are essential gear!
I do not know which kind person for the first time came up with this nonsense. But nonsense, as you know, the survivors. And already on the forums of "experts", they are exchanged by the views that are submitted by theoretical justifications under the obvious nonsense. And on the traffic lights standing in front of you the machine now and then wink by lanterns rear stroke, speaking that the owner of the box-machine switches it from the mode D somewhere else. As is known, the selector usually passes through the intermediate position of the reverse - R.
It's a shame for fellow citizens. Guys, think - why engineers? So you jerked the lever on each traffic light? Or is it still in order to reduce communication with a box to a minimum, assigning all the automation?
It is clear that "legs grow" from mechanical boxes - there is a vital switch to neutral at stops. Of course, it was not familiar, finished how long to stand with a squeezed clutch, but life quickly had themselves with their worn outward bearings and other troubles. Yes, and there was no point in this: it was still possible to touch something from the first transfer, but not with the fourth ...
But why mock the machine?
I could not find common sense in such an algorithm. Perhaps the only acquittal option is, for example, parking in front of the barrier, which threatens to delay for 10 minutes, or even more. In this case, it is really possible to go to the position P, let's relax with the right leg. But it is categorically impossible to switch to neutral: it will end badly! If drivers know perfectly on machines with mechanics that the chamber of the same traffic light can turn under the slope, then the holders of automata from such focus have long been looked away. If the selector in P, then the car does not move anywhere, and if in D or in R, then the leg must be on the brake. But voluntarily put a poor fellow on neutral is some kind of sophisticated sadism for a different direction. Or will the foot still be on the brake? Then why the whole circus? No, I do not understand ... Neutral is invented for towing a machine with a non-working engine!
And if we translate the selector in r? Again - why? Box from unnecessary switches there is better not exactly. Yes, and the engine too: as a rule, minimal turns idle move In position D above (900 versus 700), and therefore, if necessary, to quickly move from the place of the motor. It will have to work in a latitude, albeit not long. Well, why then all the television?
The above applies to. By the way, I remind you: the Bible in all cases is the instruction of the car manufacturer. If there is some recommendation there, then it must be observed. If not - do not complicate your life or a car.
Just in case, I called the solubles by me by me - from the owner of the workshop to Professor. The request was alone: \u200b\u200btry to find at least some plus in the traffic lighting of the box automatically. Only Professor found "argument": Say, the translation of the selector from the position of the D prolongs ... battery life! Why? But because the rear stop signals are extinguished, and each excess ampere grop ...
Happy way, colleagues! And do not mock the technique ... however, as always, I invite everyone to speak.
The future driver in a driving school is impoverished: on machines with manual transmission at any stops, the "handle" should be translated into the "neutral". On the "automata" "neutral" is also present, but everything is not so simple and obvious.
The mystery of the third pedal
Given that not each of the modern drivers is familiar with the third pedal, just in case, briefly explain.
If the clutch pedal is completely squeezed, it means that the clutch is turned off. When holding the pedal, the extinguishing bearing and a diaphragm clutch spring occurs. It is these "pieces" together "separated" clutch discs: presenter and slave, resulting in "receipt" of torque on the box with power aggregate stops.
If you do not remove the leg with the clutch pedal for a long time with the engine running, you can run into expensive repair in the future. But this is possible only in a long-term perspective, because the safety margin of the entire node is quite serious.
At the "automata" "neutral" is also present. But the situation with its use is more difficult.
If you climb on car forums, you can get confused. After all, the owners of steel horses with "machine guns" were divided into two opposing camps. Some promotes "tyrnay" to the position "N" at any convenient case, while others - call not to touch the selector. At the same time, the car owners, despite age, the floor and favorite kinheroev, are frowned by mud opinions and arguments of opponents. Another, so to speak, Holy War. Not such, of course, large-scale, as the confrontation of JapanOhodov with all the others, but still.
Switching fans in the "neutral" argue it as fuel savings (on the "neutral" it is consumed less), and care about the nodes and mechanisms in general. After all, in their opinion, even behind the wheel of the car with the "automatic" you can not stop thinking.
Supporters leave everything in their places - people are a little lazy (many of themselves recognize this fact) - they fear that the selector is harmful to the automatic transmission once again, and that it can lead to premature failure. In addition, you can often find the phrase: "Save fuel? "Mechanics" it was necessary to buy and take each evening how many grams of gasoline was saved while red was burning on the traffic light. "
True, the third party, which is in the middle of the battlefield. These people switch the selector in the "neutral" only when there is something in front of something capable of stopping their car for a long time (more than five minutes). And it is done for one reason - do not want to "rape" the box. And with short stops, for example, on traffic lights, such drivers about the existence of the position "n" do not even remember.
Are there any truth?
If you believe specialists to repair automatic boxes, then the right, like the wrong, there is no right in this dispute. Just need to understand that under "automata" means both hydrotransformator and robotic gearboxes. Differences between them in clutch types.
In the "classic" automatic transmission, it is hydraulic, and the "robot" - with drunk disks, as in the manual transmission.
So, on the hydrotransformers, many translate the selector to the position "n" for one reason - do not overlay the box. The snag is that a large number of car owners are very foggy and schematically imagine, because of what the box, in fact, can "steam".
Most often it happens due to oil filter. After all, he, unfortunately, can easily be hammered by sand, dust and something else in this way. In addition, the filter can easily shock sediments.
If the automatic transmission filter is already "grated Kalach" and wondered in his life a lot, then switching to the "neutral" with traffic lights, hangs in traffic jams, and so on - this is just a way to delay the visit to the service for a while. It looks like a taking anesthetic, if the tooth fell ill: how much do not take analgesics, and you have to go to the dentist.
Well, if the filter is young, cheerful and fresh, then "tyringa" is just tribute to the archaic "mechanical" past. From which you can safely refuse and use the "neutral" only in the case of short-term towing.
Legend of "Robot"
There is a common myth. It lies in the fact that robotic box Clutch discs wear even during "idling" when the machine is worth it, and the motor works. And so as not to "offend" with the dawn of the RCPP, you must always put the "neutral".
With the truth, this error does not bordate never. The fact is that the actuators (coupling and gear dispersion devices) independently, without any help disconnect the clutch when the brake pedal is squeezed.
The principle is the same as in the case of a "mechanical" box. In the distant and gloomy perspective will fail released BearingIf the transmission is turned on for a long time, and the clutch is left squeezed.
With a "neutral", for example, there is one unpleasant feature on the traffic light. After the selector was translated from the position "n" to the "D" position, it is necessary to wait a second to a second. It is necessary that the "Avtomat" manage to figure out what what, and prepare for movement. But for other participants, the movement of these seconds may seem like eternity, so they can begin frantically signal and blame the owner of the "automaton" in stupidity.
It is clear, not everyone in rudeness reacts painfully, but especially impressionable can sharply put pressure on the gas pedal. And this leads to painful shocks on the automatic transmission, which for benefits it will definitely not go.
What is the result?
From all this, you can make a simple conclusion. If the steel horse is no longer young, and the state of the filter of its box is a mystery, then switch the selector in "N" is permissible. This will pull the moment of expensive visit to the service, and will save fuel.
But it is better when buying a supported car with a "automatic", reinforce it - replace the oil with a filter. In order for the manufacturers to speak, as it were, there were neither beaks in manuals, and the "maintenance-free" gearbox does not exist in nature.
If the steel horse is new, then it absolutely no matter what type of automatic transmission it is equipped. You can switch to the "neutral" in the case when it's just too lazy to keep the brake. But at such moments, it is much more convenient to simply shake the selector to "P" and not bother the head of the dilemma: to include "neutral" or not.
All motorists know that absolutely on every car is neutral speed. However, not all, but in the particular beginners, they know exactly what tricks it is in itself, and in general it is necessary for what purposes. Drivers are interested in the question whether it is possible to use a neutral in the course of the movement of the car with an automatic box, especially when the car stops on the traffic light.
At first, we define what neutral transmission. The neutral is a certain position of the gearbox lever. The torque, with such a lever position, will be transmitted to the wheels from the motor in such a way that the machine will remain fixed when the engine is running. This definition is true and true to any transmissions - both automatic and mechanical.
What is a neutral
If on cars with mechanical transmission The role of neutrals is fully understood, and sitting behind the wheel translates the lever on this transmission Each time on the traffic light and at any stop, then, on machines with a "machine", this transmission can never be used. So for what is she needed then? And it is necessary, mainly to be able to tow the car in case of his breakdown. Only on a neutral need to tow a car, and that - quite neat.
In one situation, a neutral speed is used on the machine - this is the parking lot. Of course, many will say that "P" (Parking) is designed for these purposes, which is more comfortable in the case of parking. However, no one forbade leave the car on a neutral transmission and on the "handbrake", and therefore it is possible to use this way.
Stop on the traffic light
Practically in any settlement There are traffic lights, especially their many in the megalopolis, on which it is necessary to stop quite often when the red light lights up. What to do in this case by car drivers with automatic transmission? Need to put on a neutral or enough to press the brake pedal and continue to be in the "Drive" mode?
Different sources on this topic give out various solutions. IN this case There is no single answer. Let's try to figure out the root of the problem, relying, mainly on the user manual.
When the neutral is turned on, there is no connection between the shafts. The car can move freely, because the shaft is not blocked. It turns out that the "N" mode is very necessary for the service transport of the machine. With all this, it is fundamentally important to do this on prescribed rules.
If we talk about stops on the traffic light, then cars with a box "Avtomat" are arranged a little differently than their fellow with mechanical transmission. This mechanism has no different gears and clutch. The entire system is functioning, thanks to the operation of the torque converter, which, with the "D" mode, starts the pressure to be tightened, and this pressure transmits the torque on the wheels. At this time there is an intense lubrication of parts.
What is still going on at the time of stopping the car on the red light? Sitting behind the wheel lets the accelerator pedal, then the water pressure drops. In the similar mode, the torque converter is only lubricated, which is useful for the machine and the "Automatic" box.
But when switching to neutral speed there is no such discharge, and the machine is not lubricated. In other words, nothing good will come out of the switching on the neutral, while stopping the car with the "Automatic" box on the traffic light. Even on the contrary, frequent pressure jumps can lead to accelerated wear.
An exception is not short-term stops of the machine, but stop traffic for a longer time, this happens during the occurrence of traffic jams on the road or when the car is stopped on the gas station when the queue is there. In this case, the driver will be very uncomfortable to keep the brake pedal foot. What is still doing then? Put a car on a neutral?
And there is no again. Ideally put the car on the parking mode, and in a situation where the cork is too big, and the flow of cars is almost frozen, you can even turn off the motor. In many brands of cars, "P - Parking" is designed for the occurrence of a car, and its parking with a running engine. Therefore, in this situation, parking is better than a neutral.
Movement rolling
You can roll on the car with a mechanical transmission from a steep and long shutter to roll rolling with a neutral until the angle of inclination allows. Thus, you can also save fuel. Is it possible to make machines with a "automatic" box?
The answer is defined - under no circumstances. Lubricants that are so necessary for the movement of the car, in this case will not be, and the degree of wear will increase at times. In addition, a sharp pressure of the pressure in the "Automatic" box will also be affected, which will occur at the end of the descent from the mountain when the drive mode will be turned on after a neutral. After all, you do not stop the car completely, but to get out, after driving, turn on the "D" mode. This may be the cause of damage to the "Automatic" box.
Repair, after driving on a neutron will be wrapped with even greater expenditure than saving on fuel. Ranach, if you wish, you can simply release the accelerator pedal, but in the drive mode.
If you follow the rules described above, then you can increase the service life of the "Automatic" box own car, and if you often disseminate them - then in very soon you will have to buy a new mechanism for your car.
