Abstract
The utility model belongs to the field of clutches, in particular to a bearing clutch of an electromobile, which comprises a retainer. A separation plate is arranged in the middle of the retainer, and a clutch device is respectively arranged on two sides of the separation plate. Each clutch device comprises an angular contact bearing, a thrust sleeve and an elastic part. The elastic part is arranged on the lateral face of the separation plate, the thrust sleeve is arranged at the end portion of the elastic part, the angular contact bearing is arranged at the other end of the thrust sleeve and connected with the thrust sleeve through a chamfered groove, and the chamfered groove is arranged on the end face of the angular contact bearing. An angle block matched with the chamfered groove is arranged in the chamfered groove on the end face of the thrust sleeve. The bearing clutch has the advantages of being simple and practical in structure and small in axial bouncing and resolving the problem of large noises.
Description
Technical field
The utility model belongs to clutch field, especially a kind of electric motor car bearing clutch.
Background technique
Clutch is divided into embedded clutch, engagement sleeve and automatic clutch, and a kind of free wheel device is arranged in the automatic clutch, generally adopts free wheel device in the existing technology in the electric motor car; It mainly is made up of star-wheel, outer shroud, ball, push rod and spring, and outer shroud is made a gear usually, and sky is enclosed within on the star-wheel; In three breach of star-wheel, a roller respectively is housed, each ball is pushed in the formed wedging method of breach of outer shroud and star-wheel by spring, push rod again; Such free wheel device moment of torsion is limited, structural relaxation, and radial displacement is bigger; In use axial runout is also big, and noise is high, and its performance and function are limited.
Summary of the invention
The purpose of the utility model is to the deficiency that exists in the above-mentioned technology, proposes the electric motor car bearing clutch that a kind of axial runout is little, noise is little, and its structural stability, practicality have overcome the shortcoming that exists in the above-mentioned technology.
The technological scheme that realizes the utility model purpose is following:
The electric motor car bearing clutch, it comprises a retainer, is provided with an isolating plate in the middle of the retainer; The isolating plate both sides are respectively equipped with an engaging and disengaging gear; Each engaging and disengaging gear comprises angular contact bearing, thrust housing and elastic member, and elastic member is located at the isolating plate side, and thrust housing is located at the elastic member end; Angular contact bearing is located at the thrust housing the other end and is connected through chamfered groove with thrust housing, and the angular contact bearing end face is provided with chamfered groove.The thrust housing end face is provided with the hornblock that matches with chamfered groove, and hornblock is located in the chamfered groove, and a coupling shaft is connecting two thrust housings.
Described elastic member is a spring.
Described retainer is provided with oilhole.
The utility model has the advantages that simple in structurely, practical, axial runout is little, has solved the big problem of noise.
