What is a car clutch disc
Automobile clutch plate is a kind of composite material with friction as the main function and structural performance requirements , mainly used in automobiles, and flywheel, pressure plate and other parts together to form the automobile clutch system. Its main function is to realize the power transmission and cutting off of the engine and transmission device during the driving process of the car to ensure the smooth start, shift and stop of the car under various working conditions .
The working principle of the clutch plate is as follows:
Starting : After the engine starts, the driver disengages the clutch with a pedal to disengage the engine from the drive train, and then puts the transmission in gear. With the clutch gradually engaged, the torque of the engine is gradually transferred to the driving wheels until the car starts from a standstill and gradually accelerates .
shift : In order to adapt to changing driving conditions during the car, the transmission needs to be frequently changed to different gear. Before shifting, the clutch must be separated, the power transmission must be interrupted, the meshing gear pair of the original gear should be detached, and the circular speed of the part to be engaged should be gradually equal to reduce the impact of meshing. After shifting, gradually engage the clutch .
prevent overload : in emergency braking, the clutch can limit the maximum torque that the drive train may bear, prevent the drive train from overload, and protect the engine and drive train from damage .
Clutch plate life and replacement time:
Life : the life of the clutch disc varies due to driving habits and driving road conditions, most people replace between 100,000 and 150,000 kilometers, often run long-distance vehicles may reach more than two hundred thousand kilometers before you need to replace .
Replacement time : when feeling skidding, lack of power or clutch becomes high and loose quickly when starting is not easy to turn off, it indicates that the clutch disc may need to be replaced .
The main role of the automobile clutch plate includes the following aspects :
ensure a smooth start : When the car starts, the clutch can temporarily separate the engine from the transmission system, so that the car can start smoothly in the state of running. By gradually pressing the accelerator pedal to increase the output torque of the engine, and gradually engaging the clutch, the transmitted torque is gradually increased, so as to ensure that the car can smoothly transition from the stationary state to the driving state .
Easy to shift : in the process of driving, the clutch can temporarily separate the engine and gearbox when shifting, so that the gear is separated, reduce or eliminate the impact of shifting, and ensure the smooth shifting process .
Prevent transmission overload : when the transmission load exceeds the maximum torque that the clutch can transmit, the clutch will automatically slip, thus eliminating the danger of overload and protecting the transmission system from damage .
Reduce torsional shock : the clutch can reduce the output torque of the engine instability, reduce the impact torque caused by the working principle of the engine, protect the transmission system .
The clutch plate works : The clutch is located in the flywheel housing between the engine and the gearbox, and is fixed to the rear plane of the flywheel by screws. The output shaft of the clutch is the input shaft of the transmission. At the beginning, the clutch is gradually engaged, and the transmitted torque is gradually increased until the driving force is enough to overcome the driving resistance; When shifting, the clutch disconnects, interrupts the power transmission, and reduces the shifting impact; During emergency braking, the clutch slips, limiting the maximum torque on the drivetrain and preventing overload .
Clutch plate material : clutch plate is a kind of composite material with friction as the main function, mainly used in the manufacture of brake friction plate and clutch plate. With the improvement of environmental protection and safety requirements, friction materials have gradually developed from asbestos to semi-metallic, composite fiber, ceramic fiber and other materials, requiring sufficient friction coefficient and good wear resistance .
