Title:
COAXIAL PURE ELECTRIC VEHICLE POWER SYSTEM HAVING POWER DISCONNECTION FUNCTION AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/135407
Kind Code:
A1
Abstract:
A coaxial pure electric vehicle power system having a power disconnection function and a vehicle, the system comprising: a motor (1), a gear (2), an intermediate shaft assembly (3), a shift drive mechanism (4), a differential assembly (5), and an output shaft (6). The motor (1) is connected to the gear (2) to drive the gear to rotate; the gear (2), the intermediate shaft assembly (3), and the differential assembly (5) form a gear transmission mechanism; the intermediate shaft assembly (3) comprises an intermediate shaft (31) and a connecting/disconnecting gear (32); the shift drive mechanism (4) is used for connecting or disconnecting the connecting/disconnecting gear (32) to/from the intermediate shaft (31); when the intermediate shaft is connected to the connecting/disconnecting gear, the power is transmitted to an output shaft by means of the motor, the gear, the connecting/disconnecting gear, the intermediate shaft, and the differential assembly in sequence; and when the intermediate shaft is disconnected from the connecting/disconnecting gear, the connecting/disconnecting gear idly rotates. By disconnecting the transmission path of the intermediate shaft, a wheel end is disconnected from the motor end, thereby reducing the drag torque, effectively reducing the energy consumed by the whole vehicle, and increasing the endurance mileage.
