For light trucks, the clutch driven plate is another component of the clutch, which converts torque from the engine to the gearbox through friction, reducing the vibration and shock of the transmission system to complete the "disengagement" and "engagement" tasks.
The function of the clutch driven plate of light trucks is to transmit the friction between the flywheel, pressure plate and driven plate to the driven plate. When the driver presses the clutch pedal, the diaphragm spring drives the pressure plate to move backward through the mechanical transmission, and the driven part is separated from the driving part.
The driven plate is one of the key components of the clutch, which depends on the friction to perform the transmission function of the transmission device. In the manufacturing process of the clutch, due to the existence of material rebound deformation, it is difficult to ensure the flatness of the clutch friction plate.
The function of the clutch pressure plate and driven plate of light trucks is to transmit the engine power to the gearbox, that is, to transmit power, which is an important part of the clutch because the friction plate is combined or disengaged through friction in the clutch.
The clutch has three important functions: power transmission, power cut-off, and overload prevention. The clutch pressure plate is installed on the engine flywheel and rotates with the engine. The driven plate (i.e. the friction plate) is combined with the input shaft of the gearbox through splines. When the friction plate rotates, the input shaft of the gearbox rotates with it. When the pressure plate is pressed on the driven plate by the spring, the power is transmitted. When the pressure plate is pressed down by the clutch pedal, the pressure plate returns to its original position, and the driven plate has no force, that is, the disengagement state. If the clutch is lightly tapped, the spring of the pressure plate does not work completely, which is a semi-disengagement, also called half-linkage.
Friction clutch is the most widely used and longest history of clutches used in trucks and cars. It is basically composed of four parts: driving part, driven part, pressing mechanism and operating mechanism.
Faults of the clutch driven plate of light trucks can cause the clutch to shake when starting automatically, incomplete separation of the clutch, difficult shifting, and other problems. The driven friction plate is the worst and easiest to damage part of the clutch. If the visible damage, fracture, or burning of the friction plate occurs, the friction plate must be replaced. The overall deformation deflection needs to be checked and corrected; if the gap between the spline shaft sleeve and the output shaft spline exceeds the specification, it must be replaced.
