The present invention discloses an electric vehicle chassis applicable to the field of the electric vehicle technology. The object is to provide an electric vehicle with light weight and good driving stability. The electric vehicle chassis according the present invention comprises a frame and a power real axle, wherein the left and right rear wheels connected to the rear axle are driven by left and right motors, respectively, and a pendulum shaft is provided between the real axle and the frame for the swinging of the rear axle. Meanwhile, the rear wheels on both sides of the rear axle can also be directly driven by the respective full gear reduction motors, and the rear axle can be provided with a limiting swinging device thereon. The present invention includes characteristics such as light weight, low center of gravity, impossibility of turning over sideward during full speed steering, flexibility and automatic restoration, and is suitable for sports and recreation.

The invention claimed is: 1. An electric vehicle chassis comprising:a rigid frame;a rear axle; andan electric control system that in turn includes a power supply device, left and right controllers electrically connected to the power supply device, and a control loop controlling the actions of the left and right controllers,wherein left and right rear wheels on both sides of the rear axle are separately driven by left and right motors, respectively, and the rear axle is connected with the frame through a pendulum shaft which is provided for the swinging of the rear axle relative to the frame,wherein the left controller is electrically connected to the left motor, the right controller is electrically connected to the right motor, a Hall accelerator is provided in the control loop to operate and output signal voltages, and the left and right controllers receive the signal voltages and output the corresponding driving voltages, respectively, to control the rotating speeds of the left and right motors,wherein the frame is provided with a contact surface thereon, corresponding to which the rear axle is also provided with a contact surface, and the pendulum shaft engage in an opening of the rear axle,wherein the contact surface on the frame is a slant surface to which the pendulum shaft is perpendicular,wherein the rear axle has a recess region in which the left and right motors are located and a reduction device is provided respectively between the left motor and the left rear wheel and between the right motor and the right rear wheel,wherein the rear axle includes left and right support parts supporting the left and right rear wheels and a connecting bracket connecting the left and right support parts, wherein the connecting bracket presents a recess shape and is provided slantly downward,wherein a limiting device is provided between the rear axle and the frame to define the swinging region of the rear axle relative to the frame,wherein the limiting device includes a movable pressing plate, a resistant member biasing against the pressing plate, and a guide post for the movable pressing plate, wherein the guide post is mounted on the frame,wherein the control loop also includes steering sensors connected in series therein, the steering sensor senses and measures the steering of the front wheels and then outputs the corresponding reduction signal voltage to reduce the speed of the motor connected to the rear wheel on the inner side of the steering, andwherein the steering sensor basically comprises a magnet fastened on a steering swinging arm and left and right Hall sensors symmetrically provided on both sides of the steering swinging arm, wherein the left and right Hall sensors sense and measure the steering of the steering swinging arm and then output the corresponding reduction signal voltage.
