Description

Brake disc component based on disc brake

Technical Field

The invention relates to the technical field of brake disc structures, in particular to a brake disc component based on a disc brake.

Background

Disc brakes, which are the main form of brake brakes, gradually replace drum brakes and become the main development direction of automobile brakes due to higher reaction speed and braking efficiency compared with drum brakes, wherein disc brakes mainly comprise a brake disc rotating along with a wheel spindle and calipers driven by high pressure, and brake pads on the calipers are used for clamping the brake disc during braking so as to generate corresponding braking pressure on a vehicle to realize the deceleration effect of the vehicle.

However, in the instant of clamping a brake disc rotating at a high speed along with a wheel spindle on a caliper of the conventional disc brake, due to the large relative speed difference between the two, the brake disc on the caliper can generate a large-intensity instant impact force to cause impact damage to the brake disc to a certain extent, so that the service life of the brake disc on the caliper is reduced, and in addition, the caliper is always kept in a static state in the use process, so that granular impurities such as dust and the like can be adhered to the surface of the brake disc on the caliper, and then the brake disc can be abraded to a severe extent in the instant of contacting with the brake disc rotating at a high speed, so that the service life of the brake disc is seriously influenced.

Therefore, a brake disc component based on a disc brake is needed to solve the above-mentioned defects existing in the use process of the existing brake disc.
