Abstract

The invention relates to a self-cooling brake disc and a self-cooling brake device, and belongs to the technical field of brakes. The self-cooling brake disc comprises a disc body and an oil storage tank. The disc body is provided with a connection hole, the disc body comprises a flange piece, a connection boss and a connection disc which are connected in sequence, the connection disc comprises multiple heat dissipation holes, multiple oil inlet passages and multiple oil return passages, the multiple oil inlet passages and the multiple oil return passages are distributed around the circumferential direction of the connection disc at intervals, and the oil inlet passages and the oil return passages communicate through an annular passage. The oil storage tank penetrates in the connection hole, the oil storage tank and the flange piece are detachably connected, and the oil storage tank, the oil inlet passages, the annular passage and the oil return passages form a circulation oil passage.According to the self-cooling brake disc, the structure is simple, the cost is low, both oil cooling and air cooling are adopted, and the heat dissipation efficiency of the brake disc is improved. According to the self-cooling brake device, the self-cooling brake disc is applied, an air cooling and oil cooling dual heat dissipation structure is adopted, automatic cooling and heat dissipation of afriction pair are achieved, and the service life of the brake device is prolonged.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to a self-cooling brake disc and a self-cooling brake device. Background technique [0002] At present, brakes can be roughly divided into two categories according to the different cooling media of friction pairs: dry brakes cooled by air and wet brakes cooled by coolant. [0003] Existing wet brakes generally have forced oil cooling, so the heat dissipation effect is better than that of dry brakes, but the structure is complex, which increases the manufacturing cost, and the extra cooling cycle system increases the difficulty of vehicle design. Contents of the invention [0004] The object of the present invention is to solve the above problems and provide a self-cooling brake disc with simple structure and low cost, which adopts dual cooling of oil cooling and air cooling, improves the heat dissipation efficiency of the brake disc, and improves the above problems. [0005] Anoth...
