Abstract

The invention discloses a mechanical transmission gear-shifting power-assisting system which comprises a gear-shifting device and a power-assisting air cylinder connected with the gear-shifting device. The gear-shifting device comprises a shell, a gear-shifting guide shaft, a power-assisting input block, a power-assisting output block, a gear-selecting guide shaft, a rocker arm, a drive block, a shifting fork and a shifting fork shaft. The power-assisting air cylinder comprises a cylinder body, a power-assisting input rod, a positioning spring, a baffle ring, a clamp spring, a power-assistingoutput rod, a piston and a valve element. According to the mechanical transmission gear-shifting power-assisting system provided by the invention, an automobile transmission can be gear-shifted conveniently and stably, the comfort in gear-shifting operation is realized, and the working intensity of a driver is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile mechanical transmissions, and in particular relates to a gear shift assist system of a mechanical transmission. Background technique [0002] For large trucks, manual models are currently the mainstream in the market, but trucks are usually used in harsh environments and complex road conditions; moreover, the shifting operation of the truck transmission is complicated and the shifting force is large, which increases the driver's work intensity. [0003] For example, the Chinese patent application document with the Chinese invention patent application number 201711399398.0 discloses a two-dimensional mechanical power shifting device for an automobile gearbox, which includes two parts: an axial propulsion device and a lateral rotation control device; the axial propulsion device consists of an axial Drive motor (1), axial coupling (17), axial screw (16), axial concave slider (3), axial chute (4), ...
