Clutch cover assembly is composed of one portion of the clutch assembly, the clutch assembly is as follows: driven clutch disc assembly, clutch pressure plate and a cover assembly, the release bearing and the flywheel.
1 clutch cover assembly
The clutch cover assembly mainly consists of a rivet, transmission piece, a moisture-proof effect rivet, a support spring, the platen, the platen cover, a diaphragm spring and other components.
2. Function clutch cover
clutch has three main functions:
(1) ensure the car a smooth start. After starting the engine, the car before the start, before the driver depresses the clutch pedal, the clutch is disengaged, the engine and drive train is disengaged, then the transmission is in gear, and then gradually release the clutch pedal, the clutch is gradually engaged. In the bonding process, the engine torque is increased gradually hindered, it should also gradually accelerator pedal is depressed, i.e., to gradually increase the fuel supply amount to the engine, the rotational speed of the engine is always maintained at a minimum steady speed, and will not die. Meanwhile, since the tightness of the clutch engagement gradually increases the engine to the drive wheels through the drive train torque will be gradually increased, when the traction force sufficient to overcome the breakaway force, i.e. car accelerates from standstill and gradually moving.
(2) to achieve a smooth shift. In the vehicle is in motion, in order to adapt to changing driving conditions, power train often have to switch to a different gear to work. Gear shift type transmission generally toggle gear-gear or other means, to allow a gear pair with a gear drive launched, then make another gear position into the work gear pair. Must be depressed before shifting clutch pedal, interrupt the power transmission, the original facilitates meshing gear disengagement, while the speed of the new gear engaged with the engaging portion of the trend in the sub-synchronization, so that when brought into engagement shock can greatly reduced, thereby achieving smooth shift.
(3) a drive train to prevent overloading. When the vehicle emergency braking, if no clutch, the engine and drive train will vary rigid connection speed decreases sharply, and thus all the moving parts which would have a great moment of inertia, the clutch between the driving part and the driven part may rely on relative motion may be generated to eliminate the cause of the load exceeds its capacity for the drive train, reduce mechanical damage.
