Abstract

The invention discloses a power drive system and a vehicle. The power drive system includes: an engine, a motor generator, and a transmission. The transmission includes: a clutch; an input shaft; an output shaft, and the output shaft is provided with a reverse driven gear and a gear The driving gear corresponds to the meshing gear driven gear and output gear, and the output gear meshes with the driven gear of the final drive; the reverse gear shaft, the reverse transmission gear, and the motor generator are dynamically coupled with the driven gear of the final drive through the reverse gear shaft Connected, the reverse gear transmission gear is slidably installed on the reverse gear shaft between the first position and the second position along the axial direction of the reverse gear shaft. The driven gear is engaged, and at the second position, at least one of the reverse drive gear and the reverse driven gear is disconnected from the reverse drive gear. The reverse transmission path of the power drive system is short, the transmission efficiency of the motor generator is high, and there is no power interruption for hybrid shifting.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a power drive system and a vehicle with the power drive system. 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 can be driven by an engine and / or a motor to achieve various working conditions to improve the fuel efficiency and fuel economy of the transmission. In the related art, the length of the transmission chain from the driving force of the motor to the differential is long, the transmission efficiency is low, and the problem of power interruption is prone to occur during the shifting process, so there is room for improvement. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] The power drive system accor...
