Dust-proof automobile brake disc

Abstract

The invention discloses a dust-proof automobile brake disc, and relates to the technical field of brake discs. The dust-proof automobile brake disc comprises a brake disc body; the brake disc body comprises a first side disc and a second side disc; connection ribs are uniformly arranged between the opposite surfaces of the first side disc and the second side disc in an annular array mode; the center position of the outer side of the first side disc is provided with an installing ring; a dust-proof ring is arranged in the position, between the opposite surfaces of the first side disc and the second side disc, of the outer ends of the connection ribs in a sleeving mode; and the inner side of the installing ring is in threaded connection with a dust-proof cover matched with the second side disc. According to the dust-proof automobile brake disc, through the structural design of the brake disc body, the dust-proof ring and the dust-proof cover, the dust-proof ring adopts the inwards concave structural design, the two sides of the inwards concave position are provided with first filter holes, the dust-proof cover adopts the conical filter barrel structural design, the end of a conical filter barrel is provided with a dust-proof shell, filter hole blocking caused by gravel flying is avoided, normal flowing of airflow of a ventilation channel inside the brake disc is ensured, the service life of the brake disc is prolonged, and the practicality is high.

Description

technical field [0001] The invention belongs to the technical field of brake discs, in particular to a dust-proof automobile brake disc. Background technique [0002] Disc brakes are composed of a brake disc connected to the wheel and a brake caliper on the edge of the disc. When braking, high-pressure brake fluid pushes the brake block to clamp the brake disc, thereby producing a braking effect. [0003] Some existing brake discs filter the flowing air in the ventilation channel by setting the filter on the surrounding side and one side, so as to avoid the internal blockage of the ventilation channel, but when the car is running, it will drive a large amount of gravel flying, During the flying process, it will directly fall on the surface of the filter screen, which will cause the filter screen to be blocked, thereby blocking the ventilation channel, making the brake disc often in a high temperature state, and reducing the service life of the brake disc.

Problems solved by technology

[0004] The purpose of the present invention is to provide a dust-proof automobile brake disc. Through the structural design of the brake disc body, dust-proof ring and dust-proof cover, the dust-proof ring adopts an inner concave structure design, and a third One filter hole, the dust cover adopts the structural design of the conical filter cartridge, and a protective cover is set at the end of the conical filter cartridge, which solves the problem that the ventilation channel in the existing brake disc is easily blocked
