Scheme of electrical equipment microtractor TZ-4K-14
As an example of the electrical equipment of the mini-tractor equipped with a diesel engine with electric and having lighting and switching devices, consider the electrical equipment of the microtractor TZ-4K-14, which is much more complicated by all those considered above. As a source of electric current (see Fig. 3.35), battery 17 and DC generator 18 are used. The battery is placed under the instrument shield of the microtractor and nourishes the starter 19 when the engine is started. The 150 W generator is located on the left side on the front cover of the engine. The system has a voltage of 12 V and serves to power various devices and systems, as well as charging the battery. The generator rotor is driven by a wedge strap from the engine camshaft. The same belt is used to drive the cooling system fan. The belt tension is adjustable by turning the generator that has
the ability to change your position relative to the front cover of the crankcase.
The direct current regulator 15 consists of three separate relays: reverse current relay, voltage controller and current limiter. The reverse current relay is used to automatically connect the battery with the generator, if the voltage on the terminals of the generator reaches 12 V. In this case, the battery is charging. With a smaller voltage, this chain is broken, protecting the battery from discharging to the generator. The voltage regulator serves to stabilize the voltage on the terminals of the generator when it changes its speed or load in the circuit of the electrical current consumers. The current limiter protects the generator from overloads arising in the event of a large number of consumers or a discharged battery. When overloading the current in the windings of the generator anchor increases significantly, which leads to their overheating and failure.
The electrical equipment of the microtractor has a weight switch 16 and the electrode button 20. The battery charging is controlled by a signal lamp 21. The inclusion of the microtractor electrical equipment system is carried out by a special switch-switch 22, which has three positions of the key, which ensures the operation of the devices from the generator or from the battery. Fuses 6 protect the electrical equipment from high voltage electrical equipment. For convenience, a portable lamp can be connected via a power outlet 5 to the electrical system. Electric beep
4 is associated with a current source through the signal turning button 3. The headlights 1 and 24, the rotation indicators 2 and 23 are connected to the electrical equipment system through three- and. Four-terminal pads 25 and 26. The switch indicator switch 8 is associated with the electrical system through the switch 7 and the terminal box 9, to which the lamp 14 is connected, signaling the operation of the rotation indicators. Pointers of rotation 10, 13 and overall lights connect to the system through a five-mone block 11. The semi-contact socket 12 serves to connect the electrical equipment of the trailer.

On modern tractors, combines and cars, various elements of electrical equipment are widely used. Their number has recently increased significantly. If in 1960, on average, 20 items of electrical products were used on the tractor, then at present, for example, on the T-150K tractor, there were 85 of them. All of these elements using wire bundles are connected to the electrical circuit. Currently, with traditional electrical schemes, it is difficult to find in the beams of the wires you need, determine the features of connecting a ka-somewhere unit or electrical equipment. Therefore, more appropriate fundamental electrical diagrams are displayed as shown in the figure.
On this scheme, it is easy to trace a chain by which the voltage comes from power supply to the consumer. The scheme is indicated, through which fuse, the contact of the terminal block and the plug connector is powered by this consumer.
The circuit of the tractor electrical equipment is represented as 15 functional followers designated from T to XV. Each of them shows the flow of supply voltage from the fuse block to each specific unit or instrument.
Scheme of the generator set. It ensures the excitation of the generator, the supply of voltage from it to the fuse block and adjustment of the supply voltage. During the operation of the generator, its self-excitation is carried out, as well as charging (recharging) of the battery.
The most common settings of the generator set are most often: poor electrical contact between terminals and wires connecting the relay controller with the generator in the plug connector or in the ignition lock circuit; Unreliable electrical contact of the relay controller or generator with a "mass" of the tractor; Incorrect adjustment of the relay controller, the malfunction of the battery, the relay controller, the generator, the failure of the fuses.
Checking starting with the degree of charge of the battery, the output voltage of the generator and the voltage on the terminal in the relay regulator are determined. If everything is in order, the malfunction should be signed in the connection chain.
All consumers of the electrical equipment system voltage comes from the generator unit through fuses of fuse blocks 13 and 18.
II. Turning on the starter relay and starter starter. The voltage to winding the starter relay enters through the fuse 2 of the fuse block 13.
When finding faults, it should be remembered that the performance of the scheme depends not only on the status of the starter, but also from the state of the battery, the starter relay and the connectors, the schema elements.
Characteristic starter malfunctions; breaking in the winding of the starter relay; The deterioration of electrical contact between the brushes and the collector, which can be caused by the ingress of lubricant to the collector, etc. The deterioration of electrical contact in the places of connecting wires from the battery to the starter.
III. Sound Signal Scheme. A characteristic fault is the unsatisfactory status of the audio signal button or open the audio winding.
IV. Stop circuit. Most often fails the "Stop" switch.
V. Scheme of inclusion of electric motors of blowing fans and cabins.

VII. Scheme of the rear headlights and cab lighting.
VIII. The inclusion circuit on the overall lights and the lighting of the license plate.
IX. Middle light inclusion scheme.
X. Far Light inclusion scheme.
For Felt IV, VI, VII, VIII, IX, X, the characteristic malfunction is the lack of reliable electrical contact between the terminal of the electric bulb and the headlights, rear headlights, lanterns, plafones. This is explained by their oxidation from environmental impact.
Xi. Water temperature signaling diagram in engine cooling system.
XII. Scheme of the sensor and water temperature pointer in the engine cooling system.
XIII. Sensor diagram and emergency pressure alarm in the engine lubrication system. The most common malfunction to the XI, XII and XIII is the failure of sensors that are not subject to repair.
XIV. Ignition scheme with magneto m 124-61 and spark 200 (A11U) candle. It is often incorrectly installed the moment of ignition, the tightness between the body and the candle insulator is disturbed, the high voltage wires are damaged and a breakdown occurs on the "mass" or an opening of the high voltage wire; The gap between the candle electrodes is disturbed.
XV Scheme of engine heating system.
For all, the electrical equipment fell by a characteristic fault is the lack of reliable electrical contact between the terminals and wires of the wiring, between the plug connector.
The technical condition of consumers, the wiring of the electrical equipment of the tractors can be checked visually and measuring instruments or control electrollamp.
We visually determine the presence of traces of the electrical wiring and elements of the circuit, wiring breaks, mechanical damage to the elements of the electrical equipment system.
To identify a malfunction in the wiring and a number of devices, you can be a control lamp, which is an electro-block with a voltage of 12 V, 1.5 sch with two wires soldered to it with clips at the ends.
When checking, one of the wires join the "mass" of the tractor, and the second alternately touches the instrument shield clamps, block terminals, plug connectors in the direction from the source to the desired consumer. If the light lights up in all control points of the chain, then the power supply circuit is proper. When the light bulb in one of the points does not light up, the fault should be signed on the site between this point and the previous checkpoint.
In addition to the control lamp, you can check the voltmeter. The principle of verification is similar to the principle of checking using a control lamp, only in this case, the malfunction is judged by the lack of an instrument reading. Checking the voltmeter is more accurate, as it allows you to determine the places of bad contact of the wiring. For example, if the value of the measured voltage at a certain point of the circuit is significantly lower than the power supply voltage, then either at this point, or on the site between this point and the previous one there is a significant voltage drop, that is, a malfunction.
The practical application of the electrical equipment of the machines showed its significant advantages. In particular, the time for finding malfunctions and failures of electrical wiring, devices and other electrical equipment of machines is significantly reduced. The scheme is more clear not only by locksmith-electricians, but also a wide circle of mechanizers. All this contributes to the reduction of downtime, especially in the conditions of field work.

The minitractor is exactly the same agricultural machinery as the tractor, but with a slightly smaller productivity, which sacrifice for maneuverability and efficiency. In addition, some copies are so easy that is transported in the trailer. Small tractors perform all the same tasks as the analogues of a higher class. It is also possible to attach hinged equipment for processing and fertilizing soil, cleaning the territory and transportation of various goods. In addition, in many tractors, even manufactured independently, there is a drive of the rotation of the auxiliary units and hydraulics.
It differs from the motoblock, first of all, the fact that it is a complete agricultural machinery. Of course, a powerful motoblock is also a considerable functionality, but when controlling it has to go all the time. It is very tiring, especially when processing a large pashny area. And making it with a self-propelled machine, even the smallest, the operator tires much less.
Understanding all the advantages of minitractors, domestic inventors create their skillful hands, sometimes, first-class specimens, and on the Internet you can now find many descriptions, schemes and even ready-made drawings of similar homemade.
Minitractor designs
For the most part, amateur constructors in the manufacture of a tractor simply rewind some kind of serial product, adding some components and abolish others. This is an easy way, but it will not always work, because In stock There must be a complete machine.
And the design of the tractors of the homemakes created from scratch, in each case it is individual, so today the variety of solutions simply rolls.
For example, a frame for a minitractor is made by a one-piece and breaking (called "filling"), rotation - controlled wheels and on-board, the layout is classical or in the form of individual modules that allow you to change the appointment of the device. Install the hydraulic system and the power take-off shaft.
The tractor from the manufacturer at the price of homemade - the entire model range. Good attached equipment for homemade agricultural machinery buy by reference. We read in this article - how to easily assemble a mini tractor from a motor-block.
The home-made minitractor below is one of the easiest in the manufacture and allows you to dispensed with affordable materials and details.
But, of course, someone who gathered something to do, with their own hands, is recommended to have technical skills, the ability to work tool and read the drawings. And, most importantly, have a lot of time and a huge desire to do this.
Frame
It is made of metal. Calculations for strength - the case is ungrateful (and in this case - and not necessary), so it is necessary to simply put a multiple reserve in advance. Based on this, apply the channel from No. 6 to 12 - the best solution for the self-made minitractor. Do some "recesses" and "rises" of aggregates is not worth it, because It will complicate and denounce the project. The usual flat "Lestenka" is simple and accessible to many.
As practice shows for a tractor Self-modeling, it is more useful as anterior and rear traverse (cross-line) to use a larger rolling sized channel (up to 20), because Subsequently, various working bodies and accessories are attached to these traverses. And it is better to have it the shelves inside. Schevelers of spars (longitudinal beams) can be placed both inward and outward. Inside the spars, fueling and highways are laid, which are naturally protected.
In the form of the simplest frame design for homemade - a rectangle with two or more traverses, but a largest rigidity will have a frame in the form of a trapezium. The width in the front should be less for accommodation in the minimum dimensions of controlled wheels, as well as to possibly monitor the movement strictly over arable land. Places of connecting spars and traverse must be reinforced by welding Kosnok.
Layout
The relative location of the aggregates of any tractor has historically developed for a long time.
The classic layout of the self-propelled machine is as follows: The engine is located in front, longitudinally, above the front axle. The gearbox is connected to it through the clutch, then the transfer box is followed and behind it is the leading bridge. Among the shafts of the aggregates are connected by cardanov and (or) couplings.
Compliance with this scheme will be the optimal option when creating a minitractor, because Allows you to apply existing aggregates without changing them.
According to the experience of many creators of homemade tractors, it is better to combine the aggregates "at the place", not engaged in excessive drawing and calculations. The best option is to place all the main components and mechanisms of homemakes on the finished frame, setting them on temporary supports (conveniently on wooden bars), and, having found the best mutual position, make the mounting brackets. But we must not forget that all the nodes on the home-made tractor must be attached through supports, quenching vibrations (rubber pillows). It is best to borrow them from the same technique from which the aggregate is taken. Another important factor must be taken into account. This is weaving, i.e. Distribution of the total weight of the minitractor on the front and rear axles. The most acceptable option - 60% of the weight falls on the drive wheels, 40% - to managed.
Engine for homemade
From the point of view of the dialing, weight, availability and low cost in repair, most logical when making a tractor in "home" conditions to apply the engine from cars VAZ classical models - from 2101 to 2107. They can be found in good condition for the price of scrap metal. If you are lucky, then one machine can become a donor of most parts for a minitractor.
Motor with clutch and gearbox is fixed as a single block, which simplifies work on the tractor homemade and eliminates the creator from many difficulties. Mandatory on the tree of the water pump ("Pump") to install the impeller of the fan, even if it was not there. After all, the speed of agricultural machinery is much lower than the automotive, so the mode of operation of a minitractor motor is the same as when standing in a traffic jam, which is considered severe for any engine. Consequently, the radiator of the cooling system of the self-made tractor needs a compulsory blowing.
Transmission
As mentioned above, it is desirable to establish a power plant on a homemade entirely. In this case, what will subsequently become a minitractor will already have, at least four transmissions forward and one back. It remains only to coordinate the optimal turnover of the tractor engine and the desired speed. To do this, it will be quite enough dispensing box from any all-wheel drive car. The most suitable option is UAZ. By the way, from the UAZ you can use the previously considered components, but they are heavier, the flow rate of the resulting tractor will be higher, and all its power will be rarely used.
A good element for the shaft connection is an elastic coupling that is installed on the output shaft of the VAZ gearbox. Having made the flange to the transfer box, you can do without intermediate cardan. But from the "Distribution" to the leading bridge Kardan is obligatory, because The load is significantly higher there, and the coupling will not stand them.
The leading bridge during self-building the tractor is best used also from the UAZ car having onboard gearboxes. This will increase, first, cravings, and secondly, clearance (which is desirable to bring up to 450 mm). The required size of the self-made minitractor's rut \u200b\u200bis obtained by circumcision of the stockings of the bridge (narrowing it) or manufacturing spacers for fastening the wheels (expanding), because Nominal Cake UAZ - 1445mm, which does not coincide with accepted ranges for agricultural machinery (1260-1285, 1350-1370, 1490-1515, 1790-1815).
Chassis and propulsion
This system in the improved homemade minitractor almost completely repeats similar to the tractors manufactured by the industry and has differences from automotive at some important points. The main difference is the absence of the rear suspension, i.e., the presenter bridge is not attached to the cozoise on the springs, but it is rigidly fixed on it. It must be done if it is planned to make not only the tractor itself, but all the agricultural tools to it, with whom it is supposed to be used. Since such attachments, like plows, harrows, mowers and other, fastening to the back of a minitractor homemade, are very much loaded by the rear axle and, if there is on the last rear suspension, will quickly lead it into disrepair. The front axle on a self-made tractor, also, can be installed without suspension, comfort will not significantly decrease. As a turning pinion, it is convenient to use forks of cardan hinges of trucks (ZIL, KAMAZ, KRAZ), spare parts from which can be found in auto belts and in metal products. Two forks are welded to the beam, or directly to the frame, observing the alignment, and the two responses - to the swivel fists of the donor. The steering trapezium together with the steering mechanism is also borrowed.
The brake system in its "car form" on the tractor, manufactured by itself, does not make sense, because not those speeds. Just only parking brakes. However, the mechanism drive is not made from the lever, but from the pedal with a fixed pressed position. Then the homemade can also be slowed down in motion, and fixed in the parking lot. Wheels are correctly used from agricultural machinery, because They have the desired protector, but it is quite possible to adapt and tires from SUVs or light trucks, cutting on them the desired tread pattern (better - "Christmas tree", for self-cleaning). Tire pressure is selected by an experimental way to find the optimal combination of comfort and performance.
Electrician on a homemade tractor
You can apply any parts from anything, the main thing is to coincide the voltage of the generator and consumers. No need to forget that the battery is a container with an acid, so it is necessary to fix it very firmly. The recommended solution is to arrange it under the selection of a minitractor in a special box, or just in the fence.
Headlights and overall lights, as well as braking signals - elements are desirable, but not mandatory, because It was possible to exploit the result of your work only away from another transport.
Move on roads
Not all the homemakes of minitractors designers leave for general roads. And it is correct, because In our country, a number of strict requirements are listed, which should be satisfied with transport moving on them. Even if everything turned out well, the product meets all the requirements, to confirm this it will require certification that is very expensive.
Therefore, moving along the roads on the homemade tractor is prohibited. If you have to deliver it to the place of work, it is better to do it on a trailer. This is one of the reasons why homemade is trying to ease.
In addition to the instruments of the ignition system, a number of other electrical devices constituting are installed on diesel wheeled tractors. tractor electrical electrical systemwhich are needed to scroll through the crankshaft of the engine when starting, lighting the unit during night work and alarm. All these devices are made and interconnected by a single-wire diagram in which the metal parts of the tractor are used as the second wire.

When checking and adjusting the central transmission, the following is followed:
1. Production work
Clean the gearbox from dust and dirt. Drain the transmission oil. Rinse the inner cavity of the body with diesel fuel.
2. Check and adjustment of the gap in the Bearing 7205 of the shaft of the leading conical gear.
Move the leading conical gear with a lomik, and at the same time normal axial movement should not exceed 0.1 mm (the indicator is measured) and, if necessary, adjust. Dispavan the main and additional gearboxes. Unscrew the locknut at the front end of the shaft of the leading conical gear (Fig.4-5). Screwing the adjusting nut, turn your hand to the leading conical gear until there is no noticeable resistance. Conduct the nut.
3. Check and adjustment of the gap in the bearing 7306 of the center of the central transmission shaft.
Deep the foot of the indicator into the ends of the crown of the slave conical gear. Moving the driven conical gear with a passion to the left and to the right, observed the remads of the scope of the arrows. Normal axial movement should not exceed 0.15mm and, if necessary, adjust. Turning the driven conical gear, add or decrease the adjusting gaskets of bearings 7306, tired at the two ends of the center of the central transmission until there is no noticeable resistance (Fig.4-6).
4. Checking the gear gear print.
When checking special attention to pay on
Table 4-1.
4.3. Adjusting the brake
4.3.1. Adjusting the free stroke of the pedal.
The normal gap between the brake shoe and the drum is 0.5-0.7 mm, which corresponds to the free move of the pedal of 30-40 mm (Fig.4-8).
When adjusting the free stroke of the pedal, omit the lock nut 2 (Fig.4-8.4-9) brake thrust, screwing (if the pedal stroke should be reduced) or discerning (if the pedal stroke should be increased) thrust in the adjusting plug, sets the required pedal stroke ( Fig.4-10). And screw the lock nut.
Fig.4-8 Adjusting the free stroke of the brake pedal:
1,4-levers; 2-lock nuts; 3-sleeve.
4.3.2. Check and adjust the left and right brakes. The braking efficiency of both brakes should be the same. Otherwise, emergency braking with high-speed motion can lead to an accident due to uneven braking.
The difference in traces of the rear wheel slippers should not exceed 400 mm in case of emergency braking of the tractor at high speed on the horizontal portion of the road. If necessary, adjust.
When adjusting, it is advisable due to an increase in the brake clearance, which has better braking efficiency, and not a decrease in the brake clearance with worse efficiency, will achieve simultaneous braking.
4.4.regulation of the front axle and steering
4.4.1. Adjusting the front axis
The most characteristic deviations from the normal operation of the running system are the wicious and vibrations of the wheels. Possible causes: impaired bearing adjustment due to wear of conical roller bearings. Therefore, it is necessary to periodically check and adjust the gap in bearings.
When adjusting from raised front wheels, you turn over three bolts, remove the wheel hub cap, tighten the bearings, and then release the crown nut on 1/16 - 1/8 turns so that the axial gap of the bearings is in the range of 0.1-0.2mm. When the wheel rotates manually it rotates easily and without noticeable wicious. Slip the crown nut and set the cap.
4.4.2. Adjustment of the convergence of the front wheels.
The wheel convergence is determined as a variety of distances between the wheels in front and behind the level of their centers. The normal value of the convergence of the tractor -4 ~ 12mm.
During the operation of the tractor, the magnitude of the convergence of the front wheels is changing. Incompretable checks and adjustment of convergence can cause the effects and fluctuations in the wheels, and consequently, the difficulty of controlling the rotation and increased wear of tire protector.
Fig.4-11 Adjustment of convergence.
Distance between the wheels of the back b. Distance between wheels in front
Regulate the convergence of wheels by changing the length of the transverse steering thrust.
4.3. Adjusting the free stroke of the steering wheel.
Free move in tractor 15? -20? And should not exceed 30?.
If the free move of the relay wheel exceeds the allowable, it is necessary to determine the malfunction of the mechanisms included in the steering and adjust them.
4.4.3.1. Adjusting the ball pin.
Replacing the axle, or the nest and the cap, when the formed clearance due to strong wear is too large and cannot be compensated by the springs.
