Problems solved by technology

For example, the size and length of the single countershaft transmission have disadvantages under the same torque, and the double countershaft 6-speed transmission currently uses spur gear transmission, so there is still room for improvement in terms of noise, and the current six-speed transmission generally does not have forced lubrication and forced cooling function

Abstract

The invention provides a six-gear automobile transmission. The six-gear automobile transmission comprises a box body and an operation mechanism, wherein a first shaft, a second shaft and middle shafts which are located at the two sides of the second shaft and matched with the second shaft, wherein the first shaft is provided with a first shaft gear, the second shaft is provided with a first-gear-stage gear, a second-gear-stage gear, a third-gear-stage gear, a fourth-gear-stage gear, a fifth-gear-stage gear and a backward gear, and the number of the middle shafts is two. Each middle shaft is provided with a transmission gear and five driving gears, wherein the transmission gear is meshed with the first shaft gear, the five driving gears are meshed with the first-gear-stage gear, the second-gear-stage gear, the third-gear-stage gear, the fourth-gear-stage gear and the fifth-gear-stage gear of the second shaft, the backward gear on the second shaft is meshed with a backward gear idle wheel, the backward gear idle wheel is meshed with a fifth driving gear of each middle shaft, and the five driving gears and the transmission gear of each middle shaft are the same in rotation direction. The six-gear automobile transmission is high in work bearing capacity, and most importantly, the noise of the transmission is lowered.

Description

technical field [0001] The invention relates to the field of automobile transmissions, in particular to a six-speed automobile transmission. Background technique [0002] At present, the six-speed transmissions used in commercial vehicles are mainly divided into single intermediate shaft structure (most manufacturers at home and abroad) and double intermediate shaft structure (Fast Company), with the development of related technologies of auto parts and the improvement of vehicle performance requirements With the improvement of relevant laws and regulations, the existing six-speed transmission products have many shortcomings in terms of performance, economy, and environmental protection. For example, the size and length of the single countershaft transmission have disadvantages under the same torque, and the double countershaft 6-speed transmission currently uses spur gear transmission, so there is still room for improvement in terms of noise, and the current six-speed trans...
