Secure the clutch assembly to the back plane of the flywheel with the screw located in the flywheel housing between the engine and the gearbox. The output shaft of the clutch is the transmission input shaft. During driving, the driver may depress or release the clutch pedal as needed to temporarily disengage and gradually engage the engine and transmission to cut off or transmit engine input power to the transmission.
Automotive clutch function:
1. To ensure a smooth start car
2. Easy to shift
3 to prevent the drive train is overloaded
How it works: The friction between the active part and the driven part of the clutch depends on the contact surface, either the liquid is used as the transmission medium (fluid coupling) or the magnetic transmission (electromagnetic clutch) is used to transmit the torque so that both Can be temporarily separated, but also gradually engage in the transmission process allows two parts to each other.
Currently widely used in the car is a spring-loaded friction clutch (referred to as the friction clutch).
Engine torque, through the flywheel and platen and the friction plate contact surface friction effect, pass to the driven plate. When the driver depresses the clutch pedal, through the transmission of the mechanical parts, the large end of the diaphragm spring drives the pressure plate to move backward, and the driven part is separated from the active part at this moment.
Friction clutch should meet the following basic requirements:
(1) to ensure that the engine can deliver the maximum torque, and there is a certain residual torque transmission torque.
(2) can be done when separation, complete separation, soft bonding, and has good cooling capacity.
(3) Follower part of the moment of inertia as small as possible. In this way, when disengaging the clutch, the speed of the part connected with the input shaft of the transmission is relatively easy to change, thereby reducing the impact between the gears.
(4) Has the ability to ease the impact of the direction of rotation, damping the vibration in the direction, and the noise is small.
(5) pressure plate and the friction coefficient of the friction plate changes small, stable work.
(6) control effort, easy maintenance.
