Problems solved by technology

[0002] In the related technology, the power of the motor needs multi-stage transmission to be output to the wheels, the transmission efficiency is low, and the radial size of the power transmission system is too large, which makes it difficult to arrange the space of the transmission, the transmission chain is too long, and the transmission efficiency is low
In addition, the superimposition of the power of the motor and the engine on the gear will also lead to insufficient stiffness and strength of the gear
Moreover, due to the existence of multiple gears, there will also be a problem of power interruption when the motor end shifts gears

Abstract

The invention discloses a power driving system and a vehicle with the same. The power drive system includes an engine, a first motor generator and a transmission, the transmission comprises a clutch,a first input shaft, a second input shaft, a first output shaft, a second output shaft, a reverse gear shaft and a first transmission mechanism, the first end and the second end of the first transmission mechanism are in power coupling connection with a second reverse gear and a gear driven gear on the second output shaft respectively, the third end of the first transmission mechanism is connectedwith the first motor generator, and the third end of the first transmission mechanism is selectively in power coupling connection with one of the first end and the second end of the first transmission mechanism. According to the power driving system, the length of the transmission chain driven by a motor is small, the transmission efficiency is high, the problem of power interruption in the gearshifting process is solved, and the functions of parking power generation and the like can be achieved.

Description

technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to a power drive system and a vehicle with the same. Background technique [0002] In the related art, the power of the motor needs multi-stage transmission to be output to the wheels, the transmission efficiency is low, and the radial dimension of the power transmission system is too large, which makes it difficult to arrange the space of the transmission, the transmission chain is too long, and the transmission efficiency is low. In addition, the superimposition of the power of the motor and the engine on the gear will also lead to insufficient rigidity and strength of the gear. And because there are multiple gears, there will also be power interruption problems when the motor end shifts gears. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object o...
