Description

technical field [0001] The invention relates to a dual synchronous clutch and a power system, in particular to a dual synchronous clutch and planetary gear coupling dual motor power system. Background technique [0002] The new energy and electrification of automobile power has become the focus and hot spot of global development. Existing electric vehicles generally adopt a single-motor pure electric drive scheme. The operating point of the motor is strongly coupled with the operating point of the vehicle, making it difficult to optimize the efficiency of the electric drive, which shortens the cruising range of the vehicle on a single charge; because the increase in the torque of a single motor affects the system cost, some vehicles adopt the scheme of decelerating and increasing the torque of the motor with a large speed ratio , but this solution has energy loss and reliability risks caused by long-term high-speed operation of the motor. [0003] Compared with the series ...
