the middle part of the inner wall of the heat dissipation sleeve (2) is provided with an arc baffle (25);
the disc body (1) is heated, the cooling liquid in the disc body (1) absorbs heat and transfers the heat to the heat-sensitive elastic sheet (14), the middle part of the heat-sensitive elastic sheet (14) is bulged after the heat is heated, so that the cooling liquid flows in the sealing range of the heat-sensitive elastic sheet (14) to dissipate the heat, when the disc body (1) rotates, the cooling liquid can flow into the annular groove (15), a communicated loop is formed in the sealing ranges of the reflux groove (16), the annular groove (15) and the heat-sensitive elastic sheet (14) after the middle part of the heat-sensitive elastic sheet (14) is bulged after the heat is heated because the annular groove (15) is communicated with the reflux groove (16), the cooling liquid can flow in the whole loop, the cooling liquid is easy to be cooled when passing through the edge of the disc body (1), the cooling liquid absorbs heat and transfers the heat to the heat-sensitive elastic sheet (14) when flowing back into the annular groove (15), the heat dissipation of the automobile brake disc is facilitated, wind can be generated when the disc body (1) rotates, part of the wind can enter the heat dissipation sleeve (2) along the inclined surface (21) of the heat dissipation sleeve (2), the heat dissipation of the automobile brake disc is facilitated, the heat-sensitive elastic sheet (14) in the through hole (12) is enabled to dissipate heat more easily due to the fact that the heat dissipation sleeve (2) is communicated with the through hole (12), and the heat dissipation of the automobile brake disc is enhanced due to the fact that cooling liquid in the cooling groove (13) is also enabled to dissipate heat more easily through the heat-sensitive elastic sheet (14); after the wind enters the heat dissipation sleeve (2), the wind flows along the inner wall of the heat dissipation sleeve (2), and when the wind encounters the arc-shaped groove (24) and the arc-shaped baffle (25), the wind flows along the arc-shaped groove (24) and the arc-shaped baffle (25), because the edge extension line of the arc-shaped groove (24) faces the inner side of the through hole (12), and the arc-shaped baffle (25) is positioned in the middle of the heat dissipation sleeve (2), the wind flowing along the arc-shaped groove (24) is easily blown into the through hole (12), ventilation of the through hole (12) is facilitated, heat dissipation of the heat-sensitive elastic sheet (14) is facilitated, and heat dissipation efficiency of the automobile brake disc is facilitated to be improved;
part of heat on the heat dissipation sleeve (2) is easy to gather at the heat dissipation groove (22) for heat dissipation, and the heat conduction material aluminum alloy or red copper in the heat dissipation groove (22) is easy to dissipate heat, so that the heat dissipation of the heat dissipation sleeve (2) is enhanced, the disc body (1) is easy to dissipate heat, and the heat dissipation efficiency of the brake disc for the automobile is improved; and the connection strength of the heat dissipation sleeve (2) and the disc body (1) can be enhanced by the bulge (23) on the outer ring of the heat dissipation sleeve (2), and on the other hand, the heat conduction efficiency between the disc body (1) and the heat dissipation sleeve (2) can be increased by the bulge (23), so that the heat dissipation of the disc body (1) is facilitated, and the heat dissipation efficiency of the brake disc for the automobile is improved.
