The clutch device of a car is an integral part of it, without which the operation of the mechanism of a multistage gearbox is impossible, as well as the implementation of the beginning of the movement of the car and the process of complete braking.
The need for clutch
In order to understand what is the purpose of the clutch in a car, it is necessary to disassemble the principle of its operation in the general composition of the torque transmission mechanism. As you know, the engine gives movement to the car. It is he who is the source of energy and torque. The rotation of the engine crankshaft must be transmitted to the wheels in a special way. The fact is that the rotational speed of the engine elements is more than a thousand revolutions per minute, while the wheels, firstly, should be able not to rotate at all, and secondly, in the case of rotation, have a frequency that is an order of magnitude lower. For these purposes, the chassis of the car, of which the clutch is a part, serves.
Clutch problem
From the need to use a clutch device, its task also follows - to couple and disengage the car engine with the wheels, when necessary. Thus, it serves as a kind of key that closes and opens the mechanical circuit that transmits torque from the engine to the wheels. In fact, the clutch does not physically connect the engine to the wheels, but to the gearbox, which is one of the links in the chain. This is done for the case of switching the box to some other gear.
As you know, the gearbox (gearbox) consists of two axles. One axle connects to the engine and the other to the wheels. In order to change the gearbox stage while driving, it is necessary to free the gearbox from the engine. This work is performed by the clutch, as a result of which the wheels and the engine are spinning idle, and it becomes possible to control them separately. As a matter of fact, one of the variants of such control is also the process of complete braking. At the moment of pressing the brake pedal in order to stop completely, the driver also presses the clutch pedal to decouple the engine from the gearbox and, as a result, from the clutch.
Clutch device
The type of clutch device is primarily associated with the need to close the engine and wheels as gently as possible. That is why the harshness of releasing the clutch pedal affects the harshness of the vehicle's start. The clutch consists of two discs in one common body, mounted on a geometrically common axis. One part of this axle, connected to one of the discs, is connected to the wheels, and the other to the engine. One of the discs has the ability to move along the axis until it touches the second disc, as a result of which adhesion occurs.
