Problems solved by technology

However, the disadvantage of this kind of brake is that the electromagnetic brake and friction brake share the same annular area of ​​the brake disc, and the heat generated by the two will interfere with each other, which cannot completely solve the thermal decay of the brake. Disc wear will change the gap between the iron core and the brake disc, thus affecting the reliability of the car brake

Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings, as shown in the figure: the outer disc inner magnetic disc brake of the present embodiment includes a brake disc 100 installed on the rotating shaft and performs frictional braking on the edge of the brake disc 100 The friction brake device 200 includes a caliper body 201, pistons 202 located on both sides of the brake disc 100 in the caliper body 201, and friction blocks 203 installed on the piston 202. The caliper body is provided with The oil passage connected with the piston, when the oil enters the oil passage, the two pistons 202 move to the brake disc 100 respectively and make the two friction blocks 203 press the brake disc 100, and the two sides of the rotating brake disc 100 are hydraulically It is braked by the friction resistance torque of the friction block 203.

[0031] In the middle of the brake disc 100, there is a circular hole 101 concentric with it, ...

Abstract

The invention discloses an outer disc inner magnetic disc brake, which comprises a brake disc installed on a rotating shaft and a friction braking device that applies a contact braking moment to the brake disc. The middle part of the brake disc has a It also includes an electromagnetic braking device that applies a non-contact braking torque to the brake disc. The electromagnetic braking device includes a rotor ring that is installed on the round hole and rotates with the brake disc and a magnetic field located in the rotor ring. The generating body, when the rotor ring rotates with the brake disc, it cuts the magnetic force lines generated by the magnetic field generating body. The electromagnetic braking area on the brake disc is separated from the frictional braking area, which solves the problem of high friction rate and high magnetic permeability and low remanence rate. In addition, since the electromagnetic area is non-friction and wear-free, it only needs to be replaced Just replace the friction disc, saving resources and reducing maintenance costs.

Description

technical field [0001] The invention relates to an outer disc inner magnetic disc brake for braking an automobile. Background technique [0002] Disc brakes reduce the rotation speed of the rotating shaft through the friction between the brake disc and the brake block, and are widely used in automobiles and the like. Conventional disc brakes suffer from a number of problems. For example, during the continuous braking process or frequent braking of a car on a long slope, the temperature of the brake will rise sharply, which will affect the thermal degradation of the brake. As a result, it will affect the braking performance of the car, and may even lead to brake failure in severe cases. In addition, as the temperature rises, the friction of the brake block increases and the wear is serious. At the same time, braking noise and dust will be generated during the friction braking process, which will pollute the environment. In recent years, although the application of electro...
