Problems solved by technology

When matching the transmission, it is necessary to install a claw rotation mechanism or a limiting mechanism for the overrunning clutch in the direction of the rotation axis of the overrunning clutch, which will increase the axial dimension and affect the size of the entire transmission
Moreover, the active part of the existing two-way overrunning clutch can only be one of the inner star wheel or the outer ring, and the active part cannot be switched in one mechanism, so the applicability and practicability are limited

Abstract

The invention discloses a two-way overrunning clutch with a pusher dog. The two-way overrunning clutch with the pusher dog comprises an inner star wheel and a reversing guide block, wherein an outer ring is arranged at the outer side of the inner star wheel, and a roller is arranged evenly between the outer ring and the outer side surface of the inner star wheel; the pusher dog is arranged between the reversing guide block and the inner star wheel, and a pawl is fixed on the side surface of the pusher dog; the pawl is arranged on the side surface close to the inner star wheel, and a reversing sleeve is arranged on the outer side of the reversing guide block; a reversing plug pin is fixed on the reversing sleeve, and an oblique groove is formed in the pusher dog; the pusher dog is arranged between the reversing sleeve and the inner star wheel, and the reversing plug pin is arranged in the oblique groove; the surface of the inner star wheel is a regular polygon, and when the pusher dog moves to the inner star wheel, the pawl is arranged between the outer side surface of the inner star wheel and the outer ring. Since the arranged structure of the two-way overrunning clutch with the pusher dog is reasonable, requirements for different transmission torque can be met; the two-way overrunning clutch with the pusher dog has the advantages of smooth reversing, a compact structure, high integration and good stability, adaptability and practicability.

Description

technical field [0001] The invention belongs to the technical field of clutches, in particular to a two-way overrunning clutch with claws. Background technique [0002] The two-way overrunning clutch with claws is one of many types of overrunning clutches. The overrunning state of the clutch can be realized by changing the position of the claws. The movement of the claws is mainly to rotate around the rotation axis of the overrunning clutch to change the position. When matching the transmission, it is necessary to install a claw rotation mechanism or a limiting mechanism for the overrunning clutch in the direction of the rotating shaft of the overrunning clutch, which will increase the axial dimension and affect the size of the entire transmission. Moreover, the active part of the existing two-way overrunning clutch can only be one of the inner star wheel or the outer ring, and the active part cannot be switched in one mechanism, so the applicability and practicability are l...
