[0038] A brake disc assembly 1 comprises a first brake disc 11 and a second brake disc 12 arranged opposite to each other, wherein a receiving space is formed between the first brake disc 11 and the second brake disc 12 and are connected via a first connecting structure 3;

[0039] The cleaning component 2 is arranged in the accommodating space, and the upper end is connected to the brake disc assembly 1 through the second connecting structure 4. The cleaning component 2 has a cleaning portion 21 on at least one side, and the cleaning portion 21 is in contact with the inner surface of the brake disc assembly 1; when the brake disc assembly 1 rotates, the second connecting structure 4 can cause the cleaning portion 21 and the brake disc assembly 1 to move relative to each other.

[0040] Specifically, the brake disc is provided with a cleaning component 2. The cleaning component 2 is used to clean the inner surface relative to the brake disc component 1, and at the same time, the impurities accumulated on the multiple heat dissipation holes in contact are cleaned, so that the influence of impurity adsorption and accumulation on the heat dissipation of the brake disc can be reduced. The brake disc has high applicability and can be used as a front brake disc or a rear brake disc. By providing a accommodating space, on the one hand, the heat dissipation effect of the brake disc can be improved, and on the other hand, the weight of the brake disc itself can be reduced. Optionally, the first connecting structure 3 can be welded, screwed, clamped, etc., and can be a fixed connection or a detachable connection; the second connecting structure 4 can be realized by a sliding connection, a connecting rod structure, a gear transmission structure, etc. in the prior art; the cleaning part 21 can be a brush, a plurality of protrusions, etc., and the cleaning part 21 is preferably made of a flexible material, which can more easily enter the heat dissipation holes to obtain a better cleaning effect.
