Abstract
Disclosed are an electric vehicle chassis and an electric vehicle using the electric vehicle chassis. The electric vehicle chassis comprises a frame system (2), a steering motor damping system (13), a wheel system (12), a steering system (3) and a braking system (14), wherein 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; and the steering motor damping system (13) comprises a left front steering damping motor (131), a right front steering damping motor (133), a left rear steering damping motor (135) and a right rear steering damping motor (137). Driving the wheels with the hub motors can omit a traditional mechanical transmission system, so as to simplify the structure of the chassis, reduce the weight of the chassis, and also reduce the mechanical transmission loss, thereby improving the power utilization efficiency.
