Self-adaption automatic separation drive assembly and overrunning clutch thereof

Abstract

The invention discloses an overrunning clutch. The overrunning clutch comprises a gear, a one-way bearing and a one-way limiting spiral cam, wherein the outer diameter of the one-way bearing is matched with the inner diameter of the gear, and the inner diameter is matched with the outer diameter of the one-way limiting spiral cam. The invention further discloses a self-adaption automatic separation drive assembly; and the self-adaption automatic separation drive assembly comprises a box body, a main shaft, a gear base, a clutch assembly, a first-grade gear, a transmission unit and the overrunning clutch. The overrunning clutch is assembled by three parts as the gear, the one-way bearing and the one-way limiting spiral cam, finishes the effects of one-way gear transmission and spiral thrust limitation, and has such advantages as few parts, small size, convenience for assembly, stable mechanical performance and low cost. On the one hand, the self-adaption automatic separation drive assembly can adapt to different torque demands of various vehicle types; and on the other hand, the self-adaption automatic separation drive assembly can adjust a torque adjusting nut to butt against a disc spring to achieve the calibrated torque requirement, and has the advantages of simple structure, quick assembly and stable torque value.

Description

technical field [0001] The invention relates to the field of driving devices for electric vehicles, in particular to a novel overrunning clutch and an adaptive automatic separation drive assembly using the overrunning clutch, which is applicable to various land vehicles. Background technique [0002] The overrunning clutch is a basic component that appears with the development of mechatronics products. It is an important component used for power transmission and separation between the prime mover and the working machine or between the driving shaft and the driven shaft inside the machine. It is a device with a self-clutching function by utilizing the speed change of the main and driven parts or the transformation of the rotation direction. Traditional overrunning clutches generally have complex structures, many parts, and low assembly efficiency. In view of this, how to provide a new overrunning clutch to overcome the above problems has become an urgent technical problem in ...
