Description

Technical Field

[0001] The utility model belongs to the technical field of clutches and relates to a clutch housing and a clutch. Background Art

[0002] The clutch is a vital component in the automobile transmission system. Its main function is to cut off and transmit power between the engine and the gearbox, so that the driver can control the car to start, accelerate, decelerate or shift gears as needed. The clutch housing is generally composed of an inner shell and an outer shell. The end face seal design greatly reduces the gap and further enhances its protective function.

[0003] A Chinese patent with publication number CN208651474U discloses a two-way clutch, including a passive shaft, an outer ring, a roller, a compression spring, a star wheel, a cylindrical pin, and a driving shaft. A star wheel is arranged inside the outer ring, and the star wheel has an inner hole, and the inner hole is provided with a keyway. The outer circle of the star wheel and the inner hole of the outer ring are clearance-matched so that the star wheel and the outer ring are concentric and can rotate relative to each other. An inclined surface and a notch are also arranged on the upper part of the outer circle of the star wheel, a roller is arranged between the inclined surface and the outer ring, and a compression spring is also arranged between the rollers. The passive shaft is a shaft with a gear at one end, the shaft extends through the inner hole of the star wheel, and is connected to the star wheel through a key. A hole is arranged in the center of the active shaft and is sleeved on the protruding part of the passive shaft. It is installed concentrically with the passive shaft and can rotate relatively. Pin holes are symmetrically arranged on the end surface of the active shaft, and cylindrical pins are inserted into them. The cylindrical pins are inserted into the cavity formed by the lower plane of the notch of the star wheel and the outer ring and the rollers.

[0004] Combining the patent's specification and drawings, it can be seen that the connection between the outer ring and the driving shaft in a two-way clutch provided by the patent is only connected by planar contact, and the connection performance is not stable enough. Utility Model Content
