<p>A hybrid power driving system of the present invention comprises an engine (1), a first clutch (4), a transmission mechanism (28) including a transmission shaft, a first electric motor (27), a power supply and a hydraulic control system. The hydraulic control system comprises an oil container; a first hydraulic cylinder (9) which includes a cylinder (37) and a piston rod (38) to do reciprocating motion along the inner wall of the cylinder (37), used for controlling the engaged or disengaged of the first clutch (4); a first oil pump (26) driven by the first electric motor (27), configured to supply the hydraulic oil in the oil container to the cylinder (37) of the first hydraulic cylinder (9); a controller which is electrically coupled with the first electric motor (27). The hydraulic control system further comprises an additional electric motor and a second oil pump (25). The additional electric motor is electrically coupled with the power supply and the controller respectively. The second oil pump (25) is driven by the additional electric motor, used for supplying the hydraulic oil in the oil container to the cylinder (37) of the first hydraulic cylinder (9). The hybrid power driving system provided by the present invention, would not damage the engine during the operation of the vehicle.</p> |
