Abstract

The invention relates to a hybrid power driving system. According to the hybrid power driving system, a first planetary gear device includes a first sun gear, a first planet carrier, and a first ringgear; an engine is provide with an engine output shaft; a first clutch for connecting the engine output shaft with a first sun gear shaft; a second planetary gear device comprises a second sun gear, asecond planet carrier and a second gear ring; the second sun gear is provided with a second sun gear shaft; the second sun gear shaft is connected with a first motor; the first planet carrier is connected with the second gear ring; the second planet carrier is connected with the first gear ring; a second clutch is used for connecting the first sun gear shaft with the second planet carrier; a third clutch is used for connecting the first planet carrier with a power output gear; the power output gear is connected with an intermediate shaft and outputs power to a wheel end through the intermediate shaft; a first braking device is used for braking the second sun gear; a second braking device is used for braking the first gear ring and the second planet carrier; and a second motor is connectedwith the intermediate shaft and outputs power to the wheel end through the intermediate shaft. The invention also relates to a vehicle.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a hybrid power drive system and an automobile. Background technique [0002] The powertrain consists of the engine (internal combustion engine) and a drive train consisting of a transmission, differential and drive shaft. Its function is to provide the vehicle with the driving power required to drive the wheels. Internal combustion engines have a range of speeds and torques, and they work best within a small range where either fuel consumption is minimized, harmful emissions are minimized, or both. However, the actual road conditions are ever-changing, not only in the speed of the driving wheels, but also in the torque required by the driving wheels. Therefore, it is the primary task of the transmission to realize the optimal speed and torque of the internal combustion engine, that is, the optimal state of power, and a good match with the power state of the drive wheel.
