Abstract

The invention discloses a transmission device with cantilever-type reverse gear aid, relating to the technical field of automotive transmission. The device comprises a reverse gear shaft clamp spring, a transmission intermediate plate, a reverse gear shaft, a needle bearing, a reverse gear shaft gear and a bowl-shape protective device which are in sleeve joint sequentially, wherein the bowl-shapeprotective device is fixedly connected with the transmission intermediate plate, the reverse gear shaft, the needle bearing and the reverse gear shaft gear are all rotatably arranged in the inner cavity of a bowl-shape maintaining device, the reverse gear shaft contacts with the transmission intermediate plate and is fixedly connected with the reverse gear shaft clamp spring to realize the cantilever-type structure. The device of the invention has simple structure, less internal space occupied and low cost, and can effectively disperse the axial force and the radial force generated during theworking in reverse gear and reduce the deformation of the shaft, thereby ensuring the contact ratio of the gear and meeting the requirements of the design.

Description

technical field [0001] The invention relates to a device in the technical field of automobile transmissions, in particular to a transmission device with a cantilever type reverse gear assist. Background technique [0002] At present, the reverse gear support mechanism of the mechanical gear transmission used in automobiles mostly adopts one side of the reverse gear shaft to be pressed into the casing, and the other side is supported by means of connecting the casing such as bolts or positioning pins. Although this structure can also withstand the axial force and radial force required by the design, it has the disadvantages of taking up a large space and being unfavorable for the arrangement and assembly of the gears. [0003] After searching the prior art, it is found that the Chinese utility model patent ZL200620108931.4 describes a "reverse gear shaft locking device", which includes a reverse gear shaft, a transmission housing, an auxiliary transmission case, the reverse g...
