Abstract
The invention discloses an automobile electronic mechanical brake which comprises a brake disc. Friction plates are arranged on the two sides of the brake disc and movably arranged on a brake caliper body. The brake caliper body is fixedly arranged on the outer side of a piston. The piston is fixedly connected with a ball screw nut. The ball screw nut is movably arranged on a ball screw. The ball screw is fixedly connected with a connecting board. The connecting board is fixedly connected to the output end of a speed reducer. The input end of the speed reducer is fixedly connected with a motor. The motor drives the ball screw to rotate through the speed reducer, so that the ball screw nut moves linearly to drive the piston to move linearly. The piston acts on the friction plates through the brake caliper body, so that the brake disc is clamped or loosened through the friction plate, and the braking function of the brake is achieved. A traditional hydraulic or air pressure brake execution element is changed into an electric brake element, the linear control braking function is convenient to achieved, and the brand-new braking technology is acquired. The invention further discloses a braking method of the automobile electronic mechanical brake.
