The clutch cover assembly is mainly composed of rivets, transmission plates, moisture-proof rivets, support springs, pressure plate, pressure plate cover, diaphragm spring and other parts.
The clutch has three main functions:
(1) Ensure that the car starts smoothly. After the engine is started and before the car starts, the driver first steps on the clutch pedal to disengage the clutch to disengage the engine from the driveline, then put the transmission in gear, and then gradually release the clutch pedal to gradually engage the clutch. During the engagement process, the resistance torque received by the engine gradually increases, so the accelerator pedal should be stepped down gradually at the same time, that is, the fuel supply to the engine should be gradually increased so that the engine speed is always maintained at the lowest stable speed without stalling. At the same time, due to the gradual increase in the tightness of the clutch engagement, the torque transmitted by the engine to the driving wheels through the driveline gradually increases. When the traction force is sufficient to overcome the starting resistance, the car starts to move from a standstill and gradually accelerates.
(2) Achieve smooth gear shifting. In the driving process of a car, in order to adapt to changing driving conditions, the transmission system often needs to change different gears to work. To realize the gear shift of the gear transmission, it is generally to toggle a gear or other gearshift mechanism to push a gear pair of the original gear out of the transmission, and then make the gear pair of the other gear enter the work. Before shifting gears, the clutch pedal must be depressed to interrupt the power transmission to facilitate the disengagement of the meshing pair of the original gear. At the same time, the speed of the meshing part of the new gear meshing pair gradually tends to be synchronized, so that the impact during engagement can be greatly increased. Reduced to achieve smooth shifting.
(3) Prevent the drive train from overloading. When the car is in emergency braking, if there is no clutch, the engine will sharply reduce the speed due to the rigid connection with the driveline, so all the moving parts in it will generate a large moment of inertia, which can rely on the clutch between the driving part and the driven part. The possible relative motion can eliminate the load that exceeds the load-carrying capacity of the drive train and reduce the damage of the mechanical parts.
