What is the working principle of clutch pressure plate?

When the diaphragm spring is installed between the clutch cover and the pressure plate, the pressure generated by the pre-tightening deformation on the pressure plate compresses the driving and driven parts of the clutch, that is, the clutch is in the engaged state. The power of the engine is transmitted to the driven plate through the flywheel, clutch cover and pressure plate connected to the crankshaft, and then to the input shaft of the transmission through the spline sleeve of the driven plate. The working characteristic of this process is that the torque and speed transmitted by the driving and driven parts of the clutch are the same, and there is no speed difference and sliding wear between the driving and driven parts. Working principle of clutch: 1. The clutch plays a role when the vehicle starts and shifts gears. At this time, there is a speed difference between the first shaft and the second shaft of the gearbox. Only after the power of the engine is cut off from the first shaft can the synchronizer keep the speed of the first shaft and the second shaft synchronized. 2. After the gear is engaged, the shaft is combined with the engine power through the clutch, so that the power can be continuously transmitted. In the clutch, there is also an indispensable buffer device; 3. It consists of two disks similar to a flywheel, with rectangular slots in which springs are installed. In the case of violent impact, the springs between the two disks interact elastically to buffer external stimuli and effectively protect the engine and clutch; 4. In the clutch accessories, the strength of the pressure plate spring, the friction coefficient of the friction plate, the diameter of the clutch, the position of the friction plate and the number of clutches are the key factors that determine the performance of the clutch. The greater the spring stiffness, the higher the friction coefficient of the friction plate, the larger the diameter of the clutch and the better the performance of the clutch.
