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 outside-disc inside-magnet disc brake. The outside-disc inside-magnet disc brake comprises a brake disc, a friction braking device and an electromagnetic braking device, wherein the brake disc is mounted on a rotary shaft, the friction braking device exerts contact braking torque on the brake disc, a round hole which is concentric with the brake disc is designed in the middle of the brake disc, the electromagnetic braking device exerts non-contact braking torque on the brake disc, the electromagnetic braking device comprises a rotor ring and a magnetic field generating body, the rotor ring is mounted on the round hole and rotates with the brake disc, the magnetic field generating body is located in the rotor ring, and a magnetic force line that is generated by the magnetic field generating body is cut when the rotor ring rotates with the brake disc. An electromagnetic braking area and a friction braking area on the brake disc are separated so that the problem that good friction rate, high magnetic permeability and low residual magnetism rate can not be simultaneously achieved is solved, moreover, the electromagnetic area is in a non-friction mode without abrasion, a friction disc is merely required to be replaced when replacing is required, resources are saved, and maintaining costs are lowered.

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...
