Abstract

The invention discloses a power driving system and a vehicle. The power driving system comprises an engine, a plurality of input shafts, a plurality of output shafts and auxiliary output shafts, wherein the engine is arranged as being selectively in joint with at least one of the multiple input shafts, and a gear-position driving gear is arranged on each input shaft; a gear-position driven gear isarranged on each output shaft, and a gear part is arranged on one side of one of the gear-position driven gears, so that a dual gear is formed; a plurality of auxiliary gear-position driven gears arearranged on each auxiliary output shaft, and the rotating directions of each auxiliary gear-position driven gear and the correspondingly linked gear-position driven gear are the same; and a reverse-gear output gear and a reverse-gear synchronizer are arranged on one of the auxiliary output shaft in an empty sleeving mode, each reverse-gear output gear meshes with the corresponding gear part, andeach reverse-gear output gear and one adjacent auxiliary gear-position driven gear share one reverse-gear synchronizer. The power driving system has a plurality (taking ten as an example) of forward gear positions, so that power is smoother during transmitting, and transmission efficiency is high.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a power drive system and a vehicle. Background technique [0002] With the continuous consumption of energy, the development and utilization of new energy vehicles has gradually become a trend. As one of the new energy vehicles, a hybrid vehicle is driven by an engine and / or an electric motor, and has multiple modes, which can improve transmission efficiency and fuel economy. [0003] However, in the relevant technologies known to the inventor, the transmissions in hybrid vehicles generally have complex structures, few transmission modes, and low transmission efficiency. In addition, the transmissions in traditional hybrid vehicles are mostly five-speed or six-speed, and the transmission efficiency is not high. Contents of the invention [0004] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent....
