Abstract

The invention belongs to the field of new energy vehicles, and relates to a vehicle and a dual-clutch hybrid power coupling system which comprises an engine, a generator, a driving motor, a differential mechanism, a first clutch and a second clutch; the engine is connected with a driving part of the first clutch through a first input shaft; a driven part of the first clutch is connected with a driving part of the second clutch; the generator is connected with the driving part of the second clutch through a second input shaft; a driven part of the second clutch is connected with the differential mechanism; the driving motor is connected with the differential mechanism through a third input shaft. By selectively combining or separating the first clutch and the second clutch, whether the engine and the generator participate in driving or power generation can be controlled, so that multiple driving modes are realized, and higher transmission efficiency is obtained; especially, an engine direct drive mode and a dual-motor pure electric mode are achieved, the power performance of the whole vehicle is remarkably improved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, in particular to a dual-clutch 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 ...
