Transmission and vehicle

Abstract

The invention provides a transmission and a vehicle. The transmission comprises an input shaft assembly, an output shaft assembly, a reverse gear shaft assembly, a differential assembly, an operating mechanism and a housing. The operating mechanism comprises a shift shaft, a counterweight, a shifting rocker arm, a first advancing gear declutch shift shaft, a second advancing gear declutch shift shaft, a reverse gear declutch shift shaft, a one-to-second gear shift fork, a third-to-fourth gear shift fork, a fifth-to-sixth gear shift fork, and a reverse gear shift fork. The one-to-second gear shift fork sleeves the first advancing gear declutch shift shaft. The third-to-fourth gear shift fork is fixed on the first advancing gear declutch shift shaft. The fifth-to-sixth gear shift fork is fixed on the second advancing gear declutch shift shaft. The reverse gear shift fork is fixed on the reverse gear declutch shift shaft. According to the transmission provided by the invention, the fifth-to-sixth gearshift fork is fixed on the second advancing gear declutch shift shaft which is singly arranged, thereby preventing sharing of the declutch shift shaft by the fifth-to-sixth gearshift fork which is used for longest time and the shift fork at other gears, reducing the use frequency of the declutch shift shaft which corresponds with the fifth-to-sixth gear shift fork, and reducing fault rate of the transmission.

Description

technical field [0001] The invention belongs to the technical field of vehicle transmission, in particular to a transmission and a vehicle. Background technique [0002] Existing six-speed transmission is usually made up of input shaft assembly, output shaft assembly, reverse gear shaft assembly, differential gear assembly, operating mechanism and housing. [0003] In the existing six-speed transmission, the rear bearings of the input shaft and the output shaft are supported between the fourth gear and the fifth gear, so that the housing must be a three-stage structure, that is, the housing is usually composed of a transmission housing, a clutch housing and a rear gear. The cover consists of a three-stage structure shell, the gears and synchronizers inside the back cover are not well lubricated, the workload of assembly and disassembly is large, and maintenance is inconvenient. [0004] In addition, the reverse gear of the existing six-speed transmission is generally a slid...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a transmission for the defect that the fifth and sixth gear shift forks of the existing transmission share the shift fork shaft with the shift forks of other gears, which leads to an increase in the failure rate of the transmission.
