Abstract

The invention belongs to the field of new energy vehicles, and relates to a power split hybrid power coupling system and a vehicle. The power split hybrid power coupling system comprises an engine, agenerator, a driving motor, a second clutch, a third clutch, a shifter, a planet row, a first input shaft, an intermediate shaft, a first reduction gear pair and a second reduction gear pair, whereinthe first reduction gear pair and a second reduction gear pair are different in speed ratio; the is connected with a first input shaft; the first input shaft is connected with the intermediate shaft through the shifter and the second reduction gear pair; an output shaft of the generator is rotatably arranged on the first input shaft in a sleeving mode; a sun gear of the planet row is arranged on the output shaft of the generator; a planet carrier is connected with the first input shaft; and an inner gear ring is connected with the generator through the second clutch; the inner gear ring is also connected with the intermediate shaft through a third clutch and the first reduction gear pair; the driving motor is connected with the intermediate shaft, and the intermediate shaft outputs power to wheels. The hybrid power system facilitates reduction of system load, can realize multiple driving modes, is adjustable in speed ratio, has higher transmission efficiency, and improves the power performance and economy of the whole vehicle.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, in particular to a power split hybrid power coupling system and a vehicle. Background technique [0002] The powertrain consists of the engine (internal combustion engine) and a transmission system 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 ...
