Abstract

The invention discloses a hybrid car driving system which comprises a driving motor operating mode switching device, and belongs to the technical field of vehicle engineering, wherein, an engine is connected with an integral start generator coaxially; the integral start generator is connected with a first automatic clutch driving disc; a first automatic clutch driven disc is connected with a planetary gear mechanism by a driving motor; one side of the planetary gear mechanism is connected with the driving motor by a second automatic clutch, and the other side thereof is connected with a main reducer-differential mechanism; the main reducer-differential mechanism is connected with wheels by a driving axle; a power battery pack is respectively connected with a motor controller and an external power supply plug by cables; and the motor controller is respectively connected with the integral start generator and the driving motor by the cables. An outer gear ring of the planetary gear mechanism is connected with a frame fixedly. The hybrid car driving system reserves the traditional vehicle structure to a maximum extent and optimizes the working point of the engine by using double motors, thus leading the engine to operating stably in a high-efficiency and low-discharge area, simultaneously optimizing the working condition of the driving motor and prolonging the service life of the motor.

Description

technical field [0001] The invention relates to a car driving system in the technical field of vehicle engineering, in particular to a hybrid electric car driving system including a driving motor working mode switching device. Background technique [0002] With the tension of world energy and the strengthening of human environmental awareness, safety, energy saving and environmental protection have become the themes of today's automobile development. As one of the new energy vehicles, hybrid vehicles can better solve the above problems. A hybrid vehicle is a vehicle that is jointly driven by an engine and an electric motor system. The engine can be an internal combustion engine using multiple fuels; the motor can be either a permanent magnet motor or an excitation motor, a synchronous motor or an asynchronous motor. A plug-in hybrid vehicle, PHEV (Plug-in Hybrid Vehicle), can use a household power socket (such as a 220V power supply) to charge the battery while having the ...
