The main purpose of the car is to transport people and useful things. Of course, the process itself can be qualitatively different, but even a BMW of the latest model and a VAZ car have at least one general principle: with a faulty transmission, the movement of cars is impossible.
The role of automotive transmission is very important. It is she who is responsible for the clear and timely transmission of torque from the engine to the driving pair of wheels of the vehicle, and is also directly involved in changing the direction of movement of the machine. The transmission consists of several units. This is, first of all, the clutch, which regulates the joint operation of the engine and gearbox. Following the clutch, the gearbox is directly involved in the operation, with the help of which the engine power and its torque are redistributed to the drive shafts of the driving wheels. Transmissions are divided according to the principle of operation and the method of converting energy into mechanical, electrical and combined. For example, an electric transmission works with electrical energy, converting it into mechanical energy at a certain stage of operation. It should be noted that the most popular today is the manual transmission, and for some time now more and more motorists appreciate the hydromechanical, which is also called automatic. The name is not accidental, because the change in torque occurs here automatically, depending on the preset settings. Modern cars amaze with a variety of designs and principles for calculating the drive wheels. There are schemes, among which 4x4 all-wheel drive cars are in the lead, as well as somewhat less aggressive cars with front-wheel drive or rear-wheel drive. Of course, transmissions in which a different layout of the driving axles is implemented also have a different scheme for organizing the process of movement of the vehicle. So, for example, front-wheel drive cars have constant velocity joints (constant velocity joints), which are necessary to transfer force and power to the driving wheels. Rear-wheel drive vehicles have a propeller shaft for the same purpose.
