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 engine is arranged to be selectively engaged with at least one of the first input shaft and the second input shaft, the first input shaft is provided with a first-gear driving gear, a third-gear driving gear, a fifth-gear driving gear and a seventh-gear driving gear, and the second input shaft is provided with a second-gear driving gear, a forth-gear driving gear and a sixth-gear driving gear; and anupper hollow sleeve of one of the output shafts is provided with a reverse gear output gear and a reverse gear synchronizer, one side of a gear driven gear is provided with a gear part to form a dualgear, and the reverse gear output gear meshes with the gear part. The power driving system is provided with more than seven forward gears, so that transmitting of power is smoother, the transmission efficiency is high, and the more than seven different transmission speed ratios can better meet demands for power and torque of the vehicle under different road conditions.

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....
