Motion mechanism for shifting fork shaft of double-power drive system

Abstract

The invention discloses a motion mechanism for a shifting fork shaft of a double-power drive system. The motion mechanism for the shifting fork shaft of the double-power drive system comprises a shelland a shifting fork shaft; the shell is of a hollow circular ring-shaped structure; the left and right ends of the shell are circular ring surfaces with larger diameters; axial through holes which are coaxial are arranged in positions, on the external side of a circular ring surface in the middle of the shell, on the circular ring surfaces at the left and right ends of the shell; the shifting fork shaft capable of axially moving is arranged in the axial through hole; a separating groove and a jointing groove with adjacent positions are formed in the upper surface of the shifting fork shaft; aradial through hole communicating with the axial through holes is formed in the right side circular ring surface of the shell; and a limiting mechanism for accurately enabling the shifting fork shaftto be in a separating position or a jointing position is arranged in the radial through hole. According to the motion mechanism for the shifting fork shaft of the double-power drive system, by forming the axle through holes which are coaxial in the circular ring surfaces at the left and right ends of the shell and arranging the shifting fork shaft in the axial through hole, the axial moving stability of the shifting fork shaft is enhanced so that the impact caused by separating or jointing of shifting forks is reduced and the stable and reliable motion of the shifting fork shaft is guaranteed; and the motion mechanism for the shifting fork shaft of the double-power drive system has obvious use effect and is worthy of being popularized.

Description

technical field [0001] The invention relates to the technical field of dual-power separation and jointing of automobiles, in particular to a movement mechanism for a shift fork shaft of a dual-power drive system. Background technique [0002] In the field of automobile dual power separation and joint technology, shift forks are commonly used to realize the joining and separation of oppositely installed power shafts; and the part that drives the movement of the shift fork is the shift fork shaft. At present, the movement of the shift fork shaft is prone to jamming, resulting in Shifting hysteresis affects the smoothness of the movement of the shift fork shaft and the accuracy of position orientation, which in turn affects the reliability of shifting or clutching. Contents of the invention [0003] The purpose of the present invention is to provide a kinematic mechanism for a shift fork shaft of a dual-power drive system, which has the advantages of fast movement and precise...
