ELECTRIC VEHICLE

摘要

Disclosed is an electric vehicle, comprising a chassis (1), a vehicle body and a power battery (71), wherein the chassis (1) comprises a frame system (2), a steering motor damping system (13) mounted on the frame system (2), a wheel system (12) connected to the steering motor damping system (13), a steering system (3) mounted on the frame system (2), and a braking system (4) mounted on the frame system (2); and the wheel system (12) comprises a left front wheel (121) using a hub motor, a left rear wheel (123) using a hub motor, a right front wheel (122) using a hub motor, and a right rear wheel (124) using a hub motor. Driving the wheels (121, 122, 123, 124) with the hub motors can omit a traditional mechanical transmission system, so as to simplify the structure of the chassis (1) and reduce the weight of the chassis (1). Compared with a traditional electric vehicle, the electrical vehicle has a lighter weight, smaller volume, reduced mechanical transmission loss, and improved electrical energy utilization rate.
