The machine consists of several basic units, which make it possible to create and convert the energy obtained from the combustion of fuel into torque and transfer it to the wheels. These main nodes include transmission.

What is a transmission?

In mechanical engineering, a transmission is a collection of assembly units and various mechanisms that are intended to connect an internal combustion engine with drive wheels. At the same time, there are several assignments of this mechanism:

1. Transmission of torque from the car engine to the drive wheels.
2. Change traction.
3. Change speed.
4. Change the direction of the car.

Transmission is one of the main components that determines the performance of the car when driving: maximum speed, acceleration speed. The purpose of the transmission determines it as an important element of the car, for which you need to constantly monitor, diagnose and timely repair.

What are the transmissions?

To date, there are a large number of different types of transmissions, which differ from each other performance characteristics, reliability and principle of operation. According to the basic principle of operation, the following types of gearshift mechanisms in a car can be distinguished:

1. Manual gearbox is the simplest version, which is characterized by simplicity of design, reliability and long service life. However, the very fact that this type of gearbox requires human participation in the process of shifting speeds led to the formation of the basic rules for driving a car: the right interaction with the clutch, the correct engagement of speeds while driving. Example: on cars VAZ 2109, and indeed, on all VAZs before 2000, as a rule, there is a manual gearbox (mechanic).
2. An automatic transmission is an advanced system that does not require human participation in the gear shift while the vehicle is in motion. This led to the fact that on cars with automatic transmission there is no clutch pedal. However, automatic transmission is very expensive to maintain, requires constant diagnostics, has a lower degree of reliability compared to manual transmission.
3. Mixed type gearbox - allows you to switch the gearbox yourself without having to press the clutch. Most often, a similar transmission of the car is installed on the racing version of the vehicle, or comes as an additional option.

As a rule, the type of installed gearbox depends on the value of the car, its year of manufacture and class.

What does a transmission consist of?

Due to the presence of a large number of functions in this unit, its device can be called complex. The transmission device is as follows:

1. Clutch - allows you to shift gears without harming the gearshift mechanism.
2. Transmission - a node that provides the ability to control the speed and power supplied to the drive wheels by using a combination of different gears. The basic properties of the transmission depend on this node.
3. Main gear.
4. Differential.
5. Hinges of equal angular speeds.
6. Drive shafts.

It is worth considering that the front-wheel drive vehicles and the differential are located in the gearbox housing.

The principle of the transmission is as follows:

When you press the pedal, the driver activates the clutch mechanism, which connects the drive wheels with the engine. Torque is transmitted from the crankshaft to the drive shafts, and from there to the differential. Using the gear system, the torque changes its direction and is transmitted directly to the wheels.

Manual transmission – наиболее распространенный тип, который отличается максимальной простотой функционирования, именно поэтому она используется на шестерках и прочих тазах, даже после тюнинга ВАЗ 2106.

A necessary attribute of the manual transmission is the gear lever, which is installed in the car. This is necessary so that when the driver shifts, the driver can perform actions in accordance with the situation. With the help of a special thrust mechanism during movement of the lever, the gears move along the transmission axes.

The clutch allows the car to stand still or smoothly shift gears while driving. In all cars, first gear gives a lower maximum speed, but greater traction and power; the latter gear, on the contrary, gives more speed, but less power.

The transmission device depends on its type and other features of the car. After all, there are automatic and semi-automatic types of gearboxes, which have various additional mechanisms to ensure fast and smooth shifting. It should be noted that in modern cars from Germany to improve the rate of acceleration of the car to the first hundred on the speedometer used double clutch.

Transmission, as well as any other unit of the car, needs periodic diagnostics and restoration.
