Six-speed pickup car fuel-saving manual transmission

Abstract

The invention discloses a six-speed pickup car fuel-saving manual transmission, comprising a front box body, a rear box body, an input shaft, an output shaft, an intermediate shaft and a reverse idlegear shaft, wherein the input shaft is provided with an input shaft spline and input shaft constant meshing teeth; the output shaft is provided with fifth-sixth gear synchronizer assembly, output sixth gear teeth, output third gear teeth, output fourth gear teeth, output second gear teeth, first-second gear synchronizer assembly, output first gear teeth, output reverse gear teeth and a reverse gear synchronizer assembly; the intermediate shaft is provided with intermediate shaft constant meshing teeth, intermediate sixth gear teeth, intermediate third gear teeth, third-fourth gear synchronizerassembly, intermediate fourth gear teeth, intermediate second gear teeth, intermediate first gear teeth and intermediate reverse gear teeth; and the reverse idle gear shaft is provided with a reverseidle gear, and is used to reduce the transmission speed ratio of the first gear to the second gear to the third gear to the sixth gear to the reverse gear, and the gradient difference of the speed ratio of the first gear to the second gear. Through the transmission system matching optimization design with reduced speed ratio, the synchronous impulse of low gears is reduced, the shifting quality of low gears is improved, and the overall fuel consumption of a whole vehicle and the constant-speed fuel consumption of high gears are also reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle transmission, in particular to a fuel-saving manual transmission for six-speed pickup trucks. Background technique [0002] The automobile transmission transmits the power of the engine to the automobile running system at an appropriate torque and speed through the gear transmission and the gear change of the speed change mechanism, so as to meet the requirements of the automobile for traction and driving speed under different road conditions. [0003] With the continuous and rapid growth of the pickup truck industry at home and abroad, people have higher and higher requirements for the performance and fuel consumption of pickup trucks. [0004] Yet in the process of implementing the present invention, we find: the low gear of traditional pick-up car, high gear and reverse gear speed ratio are bigger, and this can cause the fuel consumption of pick-up truck type to be bigger, and shift gears in lo...
