Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a wear-resistant automobile alloy clutch plate. Background Art

[0002] The car clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed to the rear plane of the flywheel with screws. During the driving of the car, the driver can step on or release the clutch pedal as needed to temporarily separate and gradually engage the engine and gearbox to cut off or transfer the power input from the engine to the transmission, thereby playing the role of separation and closing, ensuring smooth starting of the car, easy gear shifting, and preventing transmission system overload.

[0003] The clutch plate is a component of the car clutch. The clutch pressure plate is fixed on the engine flywheel. The clutch plate is between the engine flywheel and the pressure plate. There is a spline in the middle of the clutch plate, which can fix a drive shaft. The drive shaft on the clutch plate is the power input shaft of the gearbox. The clutch plate can connect the engine and the gearbox. As the mileage of the car increases, the clutch plate will wear. If the clutch plate is worn to a certain extent, it will slip, posing a safety hazard to the driver and passengers. Most clutch plates are integral structures with poor wear resistance. They are not easy to disassemble and replace after wear, resulting in a great waste of raw materials. It also brings great inconvenience to people's use of cars and cannot meet the actual needs of modern people. Utility Model Content
