Abstract

The invention discloses a power driving system and a vehicle. The power driving system comprises an engine, a plurality of input shafts and a plurality of output shafts; the engine is arranged to be selectively connected with at least one of the multiple input shafts, and a gear driving gearwheel is arranged on each input shaft; a gear driven gearwheel is arranged on each output shaft, and the gear driven gearwheels are correspondingly engaged with the gear driving gearwheels; a reverse gear output gearwheel is arranged on one of the output shafts in a sleeving mode and a reverse gear synchronizer which is used for being connected with the reverse gear output gearwheel is further arranged on the output shaft; a gearwheel part is arranged on one side of one of the gear driven gearwheels toform a dual-gearwheel, and the reverse gear output gearwheel is engaged with the gearwheel part. The power driving system is rich in transmission mode and has a plurality (such as seven) of forward gears, and requirements for the power and the torque during driving of the vehicle can be better met.

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....
