Abstract

The invention provides an electromagnetic and friction integrated brake system and a control method thereof. The electromagnetic and friction integrated brake system comprises a friction brake, an electromagnetic brake, a permanent magnet generator, a vehicle-mounted battery and an integrated controller. The inside friction disk and the outside friction disk of the disk-type friction brake are manufactured separately and connected by use of a bolt. The electromagnetic brake is of a rotary drum type and composed of an electromagnetic brake stator and a rotor for generating electrical vortex; the electromagnetic brake stator is located between the inside friction disk and the outside friction disk and fixedly connected with a steering joint support or suspension. The permanent magnet generator is located between the electromagnetic brake and the outside friction disk, and comprises a permanent magnet and a generator stator; the generator stator is connected with the electromagnetic brake stator by use of a bolt. The electromagnetic and friction integrated brake system has the advantages that the frequency of use of the friction brake is reduced, the heat of the brake system is scattered, the stability of the braking efficiency of the vehicle is improved, partial braking energy is recovered, and the braking noise is reduced and the consumption of energy of the whole vehicle during running is also reduced.

Description

technical field [0001] The invention belongs to the field of car brakes, in particular to an electromagnetic and friction integrated braking system with energy recovery function and a control method thereof. Background technique [0002] The mainstream braking system installed on cars at this stage transmits the brake pedal force through the hydraulic oil circuit, thereby controlling the disc friction brake for braking. The driver steps on the brake pedal and increases the pressure of the oil circuit through the brake master cylinder. Under the action of high-pressure oil, the piston in the brake caliper pushes the brake block to press the brake disc, and the friction force generated by the friction block and the brake disc distance to brake the car. In this technical solution, there is only one source of braking torque, that is, the extrusion of the friction block and the friction disc produces braking torque, so frequent braking will generate a lot of harmful dust and bra...
