Abstract

The invention discloses a transmission, a longitudinally-arranged power assembly and a vehicle. The transmission comprises a gear shaft system, and the gear shaft system comprises an input shaft, a first intermediate shaft, a second intermediate shaft, and an output shaft, wherein the first intermediate shaft and the second intermediate shaft are in transmission connection with the input shaft through gears, the first intermediate shaft is further provided with a first main speed reduction driving gear, and the second intermediate shaft is further provided with a second main speed reduction driving gear; the output shaft is provided with a first main speed reduction driven gear and a second main speed reduction driven gear which are coaxial; the first main speed reduction driven gear is meshed with the first main speed reduction driving gear; and the second main speed reduction driven gear is meshed with the second main speed reduction driving gear, a transmission ratio between the first main speed reduction driving gear and the first main speed reduction driven gear is different from the transmission ratio between the second main speed reduction driving gear and the second main speed reduction driven gear, and the speed ratios of different gears can be more conveniently and reasonably configured.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a transmission, a longitudinal power assembly and a vehicle. Background technique [0002] The structure of the existing transmission is relatively single, and there are unreasonable parts in design. [0003] Therefore, how to provide a new transmission is still a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] The purpose of the present invention is to provide a transmission, a longitudinal power assembly and a vehicle, wherein the transmission is more convenient to rationally configure the speed ratios of different gears. [0005] In order to solve the above technical problems, the present invention provides a transmission, including a gear shaft system, the pinion shaft system includes: an input shaft; a first intermediate shaft and a second intermediate shaft, the first intermediate shaft, the second intermediate sha...
