The invention discloses an engineering vehicle power system, an engineering vehicle chassis and an engineering vehicle, and belongs to the technical field of vehicles. According to the engineering vehicle power system, the engineering vehicle chassis and the engineering vehicle, the engine can be connected with the motor by controlling the engine to work independently and controlling the first clutch to be combined, power generated by the engine is transmitted through the motor shaft, and a mechanical power mode is achieved; by controlling the first clutch to be separated, the engine and the motor can be disconnected, the motor is controlled to work independently, the pure electric power mode can be achieved, the mechanical power mode and the pure electric power mode can be redundant to each other, and the power failure risk is reduced. Meanwhile, the first clutch is controlled to be combined, the engine and the motor are controlled to work at the same time, the torque generated by the engine and the torque generated by the motor can be coupled, a hybrid power mode is achieved, and the power performance of the engineering vehicle is improved.
本发明公开了一种工程车动力系统、工程车底盘及工程车,属于车辆技术领域。本发明的工程车动力系统、工程车底盘及工程车,通过控制发动机单独工作,并控制第一离合器结合,可使发动机与电动机连接,通过电机轴传递发动机产生的动力,实现机械动力模式;通过控制第一离合器分离,可使发动机与电动机断开,并控制电动机单独工作,可实现纯电动力模式,且机械动力模式与纯电动力模式能够互为冗余,降低了动力失效风险。同时,通过控制第一离合器结合,并控制发动机和电动机同时工作,可使发动机产生的扭矩与电动机产生的扭矩耦合,实现混合动力模式,提升了工程车的动力性能。
