Abstract

The invention discloses a power driving system and a vehicle. The power driving system comprises an engine, a first input shaft, a second input shaft and a plurality of output shafts, wherein the first input shaft is sleeved with the second input shaft; the engine can be selectively in joint with at least one of the first input shaft and the second input shaft; a first-gear driving gear, a third-fifth-gear driving gear and a seventh-gear driving gear are arranged on the first input shaft, and a second-gear driving gear and a fourth-sixth-gear driving gear are arranged on the second input shaft; a reverse-gear output gear and a reverse-gear synchronizer for being in joint with the reverse-gear output gear are arranged on one of the output shafts in an empty sleeving mode; and a gear part isarranged on one side of a first-gear driven gear, so that a dual gear is formed, and the reverse-gear output gear meshes with the gear part. The power driving system has a plurality (taking seven asan example) of forward gear positions, so that power is smoother during transmitting, and transmission efficiency is high; and requirements for power and torque by the vehicle under different road conditions can be better met through the multiple (taking seven as an example) different transmission ratios.

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....
