Technical Field

The invention relates to the technical field of clutches, in particular to a spring inclined assembled clutch.

Background

The clutch is installed between the engine and the transmission, and the function of the clutch is as follows: firstly, the engine and the transmission can be gradually jointed, so that the stable starting of the automobile or the motorcycle is ensured; secondly, temporarily cutting off the connection between the engine and the transmission so as to facilitate gear shifting and reduce impact during gear shifting; thirdly, can play the separation effect when the car emergency braking, prevent transmission system overload such as derailleur to play certain guard action.

The shoe-type automatic clutch in motorcycle clutch is usually used in some mini-motorcycles, the driving part is a fixed seat driven by crankshaft, three shoe assemblies are arranged on the fixed seat, the shoe is hinged on the fixed seat by pin shaft, the spring pulls the shoe to the center of crankshaft, so that a certain gap is kept between the shoe of the shoe assembly and the clutch disk of the driven part. When the rotating speed is increased, the centrifugal force generated by the shoe block is greater than the pulling force of the spring and is thrown outwards, and when the centrifugal force reaches a certain value, the shoe block is engaged with the clutch disc to generate friction force to drive the driven part to rotate so as to transmit power.

In a shoe type automatic clutch in a motorcycle clutch, a driving part is a fixed seat driven by a crankshaft, three shoe assemblies are arranged on the fixed seat, and each shoe is hinged on the fixed seat by a pin shaft; when the motorcycle starts and normally runs, the engine can vibrate, and due to the fact that a proper gap exists between the pin hole in the shoe block and the pin shaft inserted into the pin hole in the shoe block, the gap can cause the pin shaft to be capable of moving and colliding in the pin hole in the shoe block, and abnormal sound is generated.

Therefore, how to prevent abnormal noise generated by the pin shaft in the shoe block automatic clutch colliding with the pin hole on the shoe block is a technical problem which needs to be solved urgently by the technical personnel in the field.
