Anti-collision dustproof novel magnetic ABS gear ring

Abstract

The invention relates to an anti-collision dustproof novel magnetic ABS gear ring which comprises a gear ring body and magnetic rubber arranged on the gear ring body, wherein an inner metal bracket used for supporting the magnetic rubber and isolated from the gear ring body is arranged between the gear ring body and the magnetic rubber; a metal protecting ring used for protecting the magnetic rubber is arranged on the magnetic rubber; and through the metal protecting ring, the poor signal problem caused by dust pollution resulted from the fact that the surface of the magnetic rubber is damagedby an external force can be solved. The metal protecting ring is beneficial to the protection of a relatively-high-hardness metal material and the high magnetic conductivity; not only can the anti-collision, anti-deformation and dustproof effects on the magnetic rubber be achieved, but also no ABS signal input errors can be caused; by utilization of the inner metal bracket and the metal protecting ring which are capable of wrapping the edge of the magnetic rubber, the poor signal problem caused by dust pollution and the damage by an external force to the surface of a magnetic rubber of a conventional magnetic ABS ring can be solved; and the anti-collision dustproof novel magnetic ABS gear is easy to manufacture, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of ABS ring gears, in particular to a novel magnetic ABS ring gear with anti-collision and dust resistance. Background technique [0002] At present, the ABS system is widely used in the automotive field. Due to its simple structure, the magnetic ABS ring gear is a combination of metal skeleton and magnetic rubber. The magnetic rubber is evenly distributed with N and S poles, replacing the traditional ABS ring gear that needs to be machined. It is only about 5-15g, which is beneficial to the goal of pro-quantization of the car, and has been widely used; because the magnetic rubber used in the ABS magnetic ring is directly exposed to the air, the rubber material itself is relatively soft, and it is easy to be damaged, deformed, and damaged by external collisions. Defects such as gravure, if the surface of the magnetic rubber is damaged, the evenly distributed N and S poles inside will be damaged, and the inac...

Problems solved by technology

[0002]At present, the ABS system is widely used in the automotive field. The magnetic ABS ring gear is a combination of metal skeleton and magnetic rubber due to its simple structure, and the magnetic rubber is evenly distributed N, S Pole, instead of the traditional ABS ring gear that needs to be processed, and the weight is only about 5-15g, which is beneficial to the goal of car pro-quantization and has been widely used; because the magnetic rubber used in the ABS magnetic ring is directly exposed to the air, the rubber material It is relatively soft, and it is easy to be damaged, deformed, gravure and other defects after being collided by external force. After the surface of the magnetic rubber is damaged, the evenly distributed N and S poles inside will be damaged. Inaccurate signal input will cause the ABS system to alarm.

In actual use, the packaging and transportation of ABS magnetic rings have high requirements on the surface protection of the magnetic rings, which increases the manufacturing cost
