Abstract

The invention discloses a two-gear gear transmission mechanism which comprises an input shaft assembly, a middle shaft assembly, a gear shifting gear shaft assembly, a differential mechanism assembly and a shell assembly; the input shaft assembly, the middle shaft assembly, the gear shifting gear shaft assembly and the differential mechanism assembly are connected to the shell assembly through bearings; and the input shaft assembly comprises an input shaft rotationally connected to the shell assembly and a first-stage driving gear connected to the input shaft. According to the two-gear gear transmission mechanism, the first-stage driven gear is meshed with a second-gear driven gear, so that the first-stage driven gear has the function of a second-stage driving gear, an original second-stage driving gear is omitted, and the three-stage two-gear four-shaft seven-gear transmission structure is achieved; and the whole transmission mechanism is simpler in structure, and transmission noise is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and particularly relates to a two-speed gear transmission mechanism. Background technique [0002] Gear mechanism is one of the most widely used transmission mechanisms in modern machinery. It can be used to transmit motion and power between any two axes in space. It has a large transmission power range, high efficiency, accurate transmission ratio, long service life and safe work. Reliability and other characteristics, especially in the gearbox of the vehicle, transmission through different gears can meet different needs of use. [0003] In the prior art, the speed ratio of the two-stage two-speed gear transmission mechanism is small, and there is no cost advantage after matching with a large motor. SUMMARY OF THE INVENTION [0004] The present invention aims to provide a gear transmission mechanism with three stages, two gears, four shafts and seven gears, which solves the p...
