Twin-shaft six-speed mechanical speed changer

Abstract

The invention discloses a twin-shaft six-speed mechanical speed changer, and provides the twin-shaft six-speed mechanical speed changer which has the advantages of multiple gears, high transmission efficiency, compact installation space, light weight, low cost, low gear shift noise and good handfeel, and is particularly suitable for medium and small torsion. The twin-shaft six-speed mechanical speed changer solves the technical problems of low transmission efficiency, large required installation space, heavy weight, high cost, high gear shift noise, poor handfeel and the like of the speed changer in the prior art, and comprises an input shaft connected with an engine and an output shaft and a differential mechanism which are engaged with the input shaft selectively, wherein the output shaft and a reverse gear shaft are parallel to the input shaft; a driving gear for realizing a first gear, a second gear, a third gear, a fourth gear, a fifth gear and a sixth gear is arranged on the input shaft; a driven gear corresponding to the driving gear on the input shaft is arranged on the output shaft; and a synchronizer is arranged on the input shaft, the output shaft and the reverse gear shaft.

Description

technical field [0001] The invention relates to a vehicle transmission, in particular to a two-shaft six-speed mechanical transmission. technical background [0002] At present, the manual transmissions on the market are mainly five-speed and six-speed transmissions, and the six-speed transmission is becoming the mainstream of manual transmission development, while the existing six-speed transmissions are generally based on high torque, mainly using a single input shaft 1. A three-shaft six-speed transmission structure with dual output shafts, but this structure has the disadvantages of many parts, large radial size, heavy weight, and high cost, and it cannot be matched with transmissions with small and medium torques. Therefore, people improve on the basis of the existing five-speed manual transmission, and develop a six-speed manual transmission suitable for small and medium torques. However, the shafting in this structure is supported by three bearings, and the axial leng...
