Clutch of electrombile bearing

Abstract

The invention belongs to the field of a clutch, and particularly relates to a clutch of an electrombile bearing. The clutch of the electrombile bearing comprises a retainer; an isolation plate is arranged in the middle of the retainer; a clutch device is arranged at each of the two sides of the isolation plate; each clutch device comprises an angle contact bearing, a thrust sleeve and an elastic component; the elastic component is arranged at the side of the isolation plate; the thrust sleeve is arranged at the end part of the elastic component; the angle contact bearing is arranged at the other end of the thrust sleeve and connected with the thrust sleeve through a chamfered groove; the chamfered groove is arranged on the end face of the angle contact bearing; an angle block matched with the chamfered groove is arranged on the end face of the thrust sleeve, and the angle block is arranged inside the chamfered groove. The clutch of the electrombile bearing has the advantages of being simple in structure and practical; the axial runout is small, and the problem of high noise is solved.

Description

technical field [0001] The invention belongs to the field of clutches, in particular to an electric vehicle bearing clutch. Background technique [0002] Clutches are divided into embedded clutches, gear clutches and automatic clutches. There is an overrunning clutch among automatic clutches. In the prior art, electric vehicles generally use overrunning clutches, which are mainly composed of star wheels, outer rings, balls, ejector rods and springs. The outer ring is usually made into a gear, which is sleeved on the star wheel. Each of the three gaps in the star wheel is equipped with a roller, and each ball is pushed to the gap between the outer ring and the star wheel by a spring and a push rod. In the wedge gap formed, such an overrunning clutch has limited torque, loose structure, large radial displacement, large axial runout during use, high noise, and limited performance and functions. Contents of the invention [0003] The purpose of the present invention is to pro...
