Abstract

The invention discloses a power driving system and vehicle. The power driving system comprises an engine, a plurality of input shafts and a plurality of output shafts, wherein the engine is arranged to be selectively engaged with at least one of the multiple input shafts, and a retaining position driving gear is arranged on each input shaft; and a retaining position driven gear is arranged on eachoutput shaft, the retaining position driven gears correspondingly meshes with the retaining position driving gears, an upper hollow sleeve in the output shafts is provided with a reverse output gearand a reverse synchronizer used for being engaged with the reverse output gear, one side of one of the retaining position driven gears is provided with a gear part to form a duplicate gear, and the reverse output gear meshes with the gear part. The power driving system has more than seven forward gears, power is made to be smoother during being transmitted, the transmission efficiency is high, andmore than seven different transmission ratios can better meet demands of the vehicle for power and torque 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....
