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.
本发明属于新能源汽车领域,涉及一种车辆及双离合混合动力耦合系统,包括发动机、发电机、驱动电机、差速器、第一离合器和第二离合器;发动机通过第一输入轴与第一离合器的主动部分相连;第一离合器的从动部分与第二离合器的主动部分相连;发电机通过第二输入轴与第二离合器的主动部分相连;第二离合器的从动部分与差速器相连;驱动电机通过第三输入轴与差速器相连。通过选择性地结合或分离第一离合器、结合或分离第二离合器,能够控制发动机、发电机是否参与驱动或发电,从而实现多种驱动模式,获得更高的传动效率;尤其是实现了发动机直驱模式和双电机纯电动模式,显著地提高了整车的动力性能,降低了成本。
