一种车辆电磁机械制动装置

The invention discloses an electromagnetic mechanical braking device for a vehicle, and belongs to the technical field of vehicle braking. The device comprises a brake disc, a caliper body, a brake assembly and an electromagnetic piston assembly, wherein the caliper body is arranged on two sides of an outer ring of the brake disc, the brake assembly comprises a first brake lining and a second brake lining which are arranged on two sides of the brake disc, the electromagnetic piston assembly comprises a first electromagnetic piston and a second electromagnetic piston which are coaxially arranged, a coil winding is arranged in the first electromagnetic piston and the second electromagnetic piston, and electromagnetic force which is mutually attracted or repelled is generated between the first electromagnetic piston and the second electromagnetic piston after the first electromagnetic piston and the second electromagnetic piston are electrified. According to the electromagnetic mechanical braking device for the vehicle, disclosed by the invention, the brake lining is directly driven to contact or separate from the brake disc through electromagnetic force, so that the active elimination or release of a braking gap can be completed under the condition that a motor reducer assembly is not started, the noise generated by mechanical transmission components such as a traditional ball screw and a gear in high-speed operation is avoided, the mechanical noise in the braking process is obviously reduced, and the response speed and the control precision are improved.
