Description

Technical Field

[0001] The utility model relates to a connecting component for a friction clutch transmission shaft. Background Art

[0002] The friction clutch is usually located between the engine and the gearbox, or combined with the gear to form a gearbox assembly with clutch, forward and reverse functions. It is the main component connecting the engine and the shaft system. The shaft system is the transmission shaft, which is a mechanical part mainly used to transmit torque and rotation. It is usually used in situations where the distance between components is far or it is not easy to transmit directly. The transmission shaft is usually composed of one or more universal joints, claw couplings and other components.

[0003] The existing connection method between the clutch and the drive shaft is relatively simple. During use, the connection is prone to loosening. The loosening of the coupling bolt will affect the change of the shaft center and the uniformity of torque transmission, thereby causing shaft vibration. When the coupling is loose, it may cause uneven torque transmission, causing vibration to change with load and thus energy loss. Therefore, in order to ensure that the coupling will not loosen and to ensure that the clutch and the drive shaft maintain synchronous transmission, a connecting component for the friction clutch and the drive shaft is required.
