Embodiment
[0018] Embodiment: a kind of automobile electromagnetic brake structure (see attached figure 1 ), including a housing 1 and a brake disc 2. There are several ring-shaped discs 3 on the outer wall of the brake disc. 4. A number of friction plates 5, a number of electromagnets 6, push plates 7 are arranged on both sides of the disc body, the push plates are arranged on the push plate, a friction plate is installed between both sides of the disc body and the push plate, the push plate and the friction plate The contact surfaces of the discs are all inclined wedge-shaped structures. The pusher plates can push the friction plates axially outward and contact the disc body. There are permanent magnets 8 on the radial outer wall of the push plate, and several permanent magnets are installed on the housing. The electromagnet, the electromagnet is electrically connected to the car VCU. Both sides of the housing inner wall facing the push plate are provided with return slots 9, and the ...

The invention discloses an automobile electromagnetic brake structure and a braking method. The structure and the braking method aim to overcome the defects that an automobile brake system cannot achieve active braking, and is low in braking response speed and high in requirement of a motor. The structure comprises a shell and a brake disc, a plurality of annular disc bodies are arranged on the outer wall of the brake disc, and the disc bodies are arranged in the shell; a plurality of braking mechanisms are uniformly distributed in the shell; each braking mechanism comprises a pushing plate, aplurality of friction plates and a plurality of electromagnets; pushing pieces are arranged on the two sides of each disc body, and the pushing pieces are arranged on the pushing plates; the frictionplates are arranged between the two sides of each disc body and the corresponding pushing piece respectively, and the contact surface of each pushing piece and the corresponding friction plate is ofa wedge-shaped structure which is obliquely arranged; the pushing pieces can push the friction plates outwards in the axial direction and make contact with the disc bodies, permanent magnets are arranged on the radial outer walls of the pushing plates, the electromagnets are arranged on the shell and correspond to the permanent magnets, and the electromagnets are electrically connected with an automobile VCU.
Description
technical field [0001] The invention relates to an automobile brake, more specifically, it relates to an automobile electromagnetic brake structure and a braking method. Background technique [0002] In the traditional automobile braking system, when braking, the driver applies force on the brake pedal, which is amplified and converted into hydraulic pressure by the vacuum booster system, and acts on the brake to achieve braking. The vacuum booster system currently used in automobiles is composed of a vacuum booster with a brake master cylinder, a vacuum tank, a vacuum pump, and a vacuum tube. The vacuum booster with a brake master cylinder uses the pressure difference between the vacuum and the atmosphere to apply pressure on the driver The braking force on the plate is amplified, and this force is transmitted to the brake master cylinder to establish hydraulic pressure to realize the transformation from pedal force to hydraulic pressure, and the brake fluid transmits the p...
