Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, and in particular to a braking device for electric vehicles. Background Technology

[0002] Electric vehicles are pure electric motor vehicles powered by batteries and driven by electric motors. The braking system of an electric vehicle includes brake pads, a pull shaft, and a return spring. The brake pads are usually arranged in two sets and are semi-circular. The two sets of brake pads are connected by two sets of return springs. When deceleration is required, the pull shaft is pulled, which pushes the two sets of brake pads to the sides, so that the brake pads contact the brake disc inside the tire, thereby completing the deceleration.

[0003] Existing braking devices rely on the one-way movement of brake pads to contact the brake disc and brake the wheel hub of an electric vehicle. This is not conducive to the two-way movement of brake pads, resulting in poor braking efficiency of the wheel hub and the inability to brake the electric vehicle in a timely manner, thus reducing the practicality of the device. Therefore, we propose a braking device for electric vehicles to solve this problem. Utility Model Content
