Abstract
The invention belongs to the technical field of hybrid power, and relates to a hybrid power driving system and a hybrid power automobile. The hybrid power driving system comprises an engine, a first clutch, an input shaft, a first gear, a single planet row, a first motor, a second gear, a second clutch, a third clutch, an intermediate shaft, a third gear, a fourth gear, a fifth gear, a fourth clutch, a sixth gear, a second motor, a seventh gear and a differential mechanism. The hybrid power driving system can achieve three hybrid drive modes and an engine direct drive mode through reasonable layout of the engine, the first motor, the second motor, the single planet row, the multiple gears and the multiple control elements (the first clutch, the second clutch, the third clutch and the fourth clutch), so that the automobile is enabled to have high transmission efficiency under the medium-high speed working condition, and the economical efficiency is good.
Description
technical field [0001] The invention belongs to the technical field of hybrid power, and in particular relates to a hybrid power driving system and a hybrid power vehicle. Background technique [0002] A car's powertrain consists of the engine (internal combustion engine) and a drivetrain consisting of a transmission, differential and drive shaft. Its function is to provide the vehicle with the driving power required to drive the wheels. 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, to achieve the optimal engine speed and torque (that is, the optimal state of power) and better match with the power state of the drive wheels is the primary task of transmission development. [0003] At pres...
