If the clutch is needed to transfer torque from the engine to the transmission, then the gearbox serves to change it depending on driving conditions. The box ensures that the car moves in reverse and long-term separation of the transmission from the engine.

The ZIL-130 gearbox has 5 gears for forward movement and one for reverse movement. The box has 3 shafts. Primary, secondary and intermediate, as well as 2 inertial synchronizers. The gears mounted on the shafts can be grouped in the required combination and obtain gear ratios corresponding to a particular gear.

Box ZIL-130 diagram

Moving the driven shaft gear forward engages first gear. 2nd gear is engaged by moving the synchronizer clutch back. If you move the synchronizer clutch forward, 3rd gear will engage. By moving synchronizer clutch 2 back, 4th gear is engaged. If you move the same synchronous clutch forward, 5th gear will engage. The intermediate shaft does not participate in the transmission of torque. Reverse gear is engaged by moving the 1st gear gear until it engages with the gear block reverse.

A gearbox in which a change in torque value is produced by changing gear ratio. Most widespread received stepwise:

gearboxes, where the gear ratio is changed by increasing or decreasing the gear ratio. Mechanisms that change the gear ratio continuously within certain limits are called continuously variable transmissions.

» The following types of continuously variable transmissions are used in cars: hydraulic (hydrodynamic and hydrostatic, otherwise called hydrostatic), mechanical (friction and pulse) and electric.

The most widely used continuously variable transmissions are hydrodynamic torque converters, which are usually installed in combination with stepped or planetary gearboxes. Such transmissions are called hydromechanical.

Step boxes They are relatively simple in design and cheaper than continuously variable transmissions, but they have a limited number of gear ratios from three to five.

By car off-road and load capacity, the number of gears increases due to the use of an additional gearbox. The higher the gear ratio of the gears in mesh, the greater the torque.

Step-by-step transmissions have forced manual control, while planetary and continuously variable transmissions are mostly semi-automatic and automatic. The five-speed gearbox is shown in Fig. 131. The primary (drive) shaft 1 is connected through the clutch to crankshaft engine. The secondary (driven) shaft is, as it were, a continuation of the primary shaft and is located on the same axis with it.

One end of the secondary shaft is mounted on a roller bearing 10 mounted at the end of the primary shaft, so the secondary shaft can rotate independently of the primary; the second end of the shaft is installed in a ball bearing 8.

Gears are mounted on the intermediate shaft 9. All of them, except the first gear gear, are made separately and secured to it with keys. To reduce noise during operation and increase durability, the gears that are in constant mesh are helical.

A design feature of the ZIL-130 car gearbox is the presence of constant mesh gears on the secondary shaft. These gears, thanks to special treatment (phosphating) of the mating surfaces of the shaft and the gears of their lubrication grooves, are installed on the shaft without special bushings and bearings.

In a MAZ-500 type gearbox, the needle bearings of the secondary shaft gears, which are in constant mesh, are lubricated with oil ... under pressure. To do this, a gear oil pump is installed against the front end of the intermediate shaft on the outside of the gearbox housing, driven into rotation from the front end of the intermediate shaft.

shaft The gears are engaged by moving the gear along the splines of the shaft. But in this case, the impact of the teeth is inevitable, since the peripheral speeds of the gears are different. For easy and shock-free gear shifting, it is necessary that the peripheral speeds of the gears being engaged are the same.

The peripheral speed of a gear depends on the number of revolutions of the shaft on which it is mounted and on its diameter: the larger the diameter of the gear and the number of revolutions of the shaft, the greater its peripheral speed. To equalize the peripheral speeds of the gears before engaging them, a special synchronizer mechanism is used, which ensures their silent and shock-free engagement.

SYNCHRONIZER

Synchronizers ensure silent operation when turned on. The difference in the rotation speed of the synchronizer clutch and the engagement of the gear is smoothly equalized due to the friction force that arises between them. The gearbox shift mechanism has a locking device that holds the shift rods in the required position.

The synchronizer for LAZ-695, LAZ-697 buses and the ZIL-130 car (Fig. 132) works as follows.

When clutch 11 is moved to the left using the shift fork, the conical bronze ring will move with it and press against the conical surface of gear 1. The conical rings 7 and the clutch ]] are not connected rigidly to each other, but through three locking pins 5 with balls and a spring. Gear 1 and rings 7 rotate at different peripheral speeds. Until these speeds become equal due to the friction force, coupling 11 will shift (Fig. 132, b).

Both bronze rings 7 are rigidly connected to each other using pins 12. The coupling 11 will move until the conical surface 10 of the coupling rests against the conical surface 9 of the pin (Fig. 132, a and d). When the speeds of the synchronizer rings 7 and the gear cone 1 are equalized, the pin 12 will be located in the center of the hole of the coupling 11, the blocking conical surfaces will separate (Fig. 132, c and d), and the coupling will continue its displacement. Its outer teeth 13 will engage with the inner teeth of the gear shaft 1, which will thus be connected via a synchronizer to the driven shaft 14.

PTO power take-off.

Its name hints at the fact that it takes part of the engine torque and transfers it to special mechanisms. This could be a hydraulic pump or attachments municipal equipment. The PTO works in close conjunction with the gearbox and is activated from the cab vehicle. A huge amount of load and work falls on this small device.

Therefore, they always strive to make it strong and durable. There are 2 types of PTO, clutch dependent and clutch independent. The first one works when the engine is running at Idling. Dependent PTO is lightweight, easy to install and requires almost no maintenance. They are mounted on manual transmission and is activated by the driver from the cab. An independent PTO can work with both manual and automatic transmissions.

It is installed on concrete mixers, road cleaning equipment, and agricultural machines. The place of registration of KOM can become a checkpoint, transfer case, engine or space between engine and gearbox. KOM is a highly durable unit, but even it can break.

Often, breakdowns are immediately visible; the PTO either stops turning on normally or begins to make loud noise. Problems are solved in different ways, starting with simply tightening the nuts and ending with complete disassembly of the PTO. In any case, without the appropriate knowledge and skills do-it-yourself repair KOM is not recommended by the manufacturer.

Every motorist who has ever encountered driving a ZIL 130 or 131 car will say with confidence that for this “ iron horse“There are practically no barriers. However, if this is your first time driving such a unit, then you will probably be interested in the ZIL 130 gear shift scheme. Moreover, it is quite original and unusual for the average motorist.

[Hide]

How does the gearbox of the ZIL 130 car work?

ZIL 130 and 131 vehicles are equipped with a three-way five-speed gearbox manual transmission gear shift. The gearbox of this vehicle allows the driver to move forward at five speeds and backward at one. You can find a drawing of the device below. As can be seen in the diagram, the ZIL 130 and 131 gearbox is equipped with two inertial synchronizers, which include the second and third, as well as the fourth and fifth.

The drive shaft, together with the gear and ring gear to activate the fifth (direct) speed, is installed in the crankcase on bearings. In addition, a cylindrical roller bearing is mounted in the bore of the pulley itself, and the secondary pulley, in turn, rests on it. The intermediate shaft in the ZIL 130 and 131 box is mounted in the lower compartment of the crankcase. There is another gear installed on this shaft, which is in regular mesh with the input shaft (ID) disk. Here, the developers of models 130 and 131 decided to install wheels of second, third and fourth speeds.

In addition, spur gears are mounted on the cardan, designed to activate reverse (reverse) gear and first gear. Also, activation of these modes is provided by a spur gear and synchronizer components mounted on the splines of the secondary pulley.

In addition, additional gears are mounted on the secondary shaft:

to engage second gear;
to activate the third mode;
to turn on the fourth.

And these gear rings, when operating, are in constant engagement with the wheels mounted on the intermediate disk. The reverse movement unit is mounted on special roller bearings, which are located on an axis in the crankcase. Here they are installed quite securely. The reverse drive cardan also works in conjunction with the idler pulley through additional wheels.

As for the inside of the crankcase, the working fluid is poured here, so this part is always closed from debris and dust. The switching mechanism itself is installed here. It should be noted that the gearbox switching mechanism on ZIL 130 and 131 is designed in the same way as on GAZ 53.

Switching circuit

The switching diagram for the ZIL 130 and 131 gearboxes is presented below. In general, the scheme is original, but if you believe the words of ZILovodov, then you can get used to it very quickly.

How does the gearbox of a car of this brand work?

When the first speed is activated on the gearbox of a car model 130 and 131, the gear wheel begins to move along the grooves and engages with the cardan of the first gearbox mode on the intermediate shaft. In this case, the torque begins to transfer from the primary pulley through gears and other auxiliary elements to the secondary disk. The gear ratio is 7.44.

When the driver engages second speed, the clutch mounted on the synchronizer begins to act on the gear teeth of this transmission. As a result of the fact that this component is already functioning from the components of the intermediate gear, the torque begins to transfer from the primary element to the secondary element. In this case, the moment passes through all the wheels with teeth, as well as the synchronizer cardan. In this case, the gear ratio will be 4.1.

When the driver activates third speed, the synchronizer disc stops affecting the parts and elements of the second gear. The clutch will move along the splines and engage with the third-mode component of the gearbox of models 130 or 131. And this element, in turn, is already engaged with the third-speed wheel of the intermediate cardan. Thus, the torque begins to transfer from the primary pulley through auxiliary elements and the clutch to the secondary pulley. The gear ratio is 2.29.

What additional things might be needed?

Here we collect various information on conversion.
What details and documents may be required.
The page is under development. Information is collected from those who have gone through the process.
If anyone knows anything, please share the information.

Regarding the registration of a converted car in the MREO:

According to our data, the car must first be submitted to the MREO with the old engine for inspection, and permission to re-equipment must be obtained from the head of the MREO or the deputy, there is a special application form.
Next, obtain a conclusion from a specialized institute (NAMI) on the possibility of this alteration, with a list of works and possible places execution. The conclusion must indicate the service number that appears on the certificate.
Next, find a service with the required certificate, perform the conversion from them, or buy documents.
After this, submit the car for instrumental control at a diagnostic station. Then again to the MREO.

More nuances:

1. The BYCHKA and ZIL-130 gearboxes are almost identical, you just rearrange the input shaft or shorten the input shaft from the ZIL-130 by about 3 cm. The difference arises due to the size of the Bychka and ZIL-130 clutch housings.
2. Here is the front support bracket - factory and no snot from the channels.
Don't reinvent the wheel, everything has already been invented a long time ago.

We have brackets.

3. The original ZIL-508 gasoline engine has a higher speed, while the D245 diesel engine has a lower rotation speed.

The gearbox ratios were selected for a more revving engine, which is why the speed of the converted car with the original 130th gearbox will drop.
You can put up with this (the car speed will be within 60 km/h), but you can install an accelerated gearbox 432930 (art. 3206-1700004-20).
The speed will increase by 20-30 km/h.
Sometimes people change the gearbox rear axle and install larger diameter tires.

4. Whether an intercooler is needed or not is up to you to decide.
