Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to a wear-resistant brake disc. Background Art

[0002] Brake discs are important components of vehicle braking systems. Brake discs are divided into solid brake discs and ventilated discs according to their structures. Solid brake discs are just a piece of metal disc with a very simple structure. Ventilated discs are divided into two forms, namely scored discs and perforated discs. Their common function is to improve the cooling performance of brake discs. Brake discs generate braking force by clamping the brake discs with brake calipers. When the brakes are applied, the brake discs clamp the brake discs to slow down or stop the vehicle. After long-term use, the surface of the brake discs will experience certain wear. In order to ensure the safety performance of vehicle brakes, severely worn brake discs should be replaced regularly. As most existing brake discs are one-piece structures, worn brake discs need to be replaced as a whole, which increases the later maintenance cost of the brake discs and affects the economic and practical performance of the brake discs. Therefore, we propose a wear-resistant brake disc. Utility Model Content

The wear-resistant plates 2 and the wear-resistant grooves 3 are adapted to each other so that the wear-resistant plates 2 can be fitted in the wear-resistant grooves 3. The inner ring surface of the wear-resistant plates 2 is annularly and equidistantly fixedly connected with a plurality of anti-torsion plugs 4. Both side surfaces of the brake disc body 1 are located on the inner sides of the wear-resistant grooves 3 and are annularly and equidistantly provided with a plurality of limiting grooves 5. The anti-torsion plugs 4 are correspondingly fitted in the limiting grooves 5. A limiting bolt 401 is threadedly connected through the anti-torsion plug 4. A locking screw groove 501 is provided on the inner surface of the limiting groove 5. The limiting bolt 401 is adapted to the locking screw groove 501 so that the limiting bolt 401 on the anti-torsion plug 4 is threadedly connected in the locking screw groove 501, thereby positioning and installing the wear-resistant plate 2 in the wear-resistant groove 3 on the brake disc body 1.

[0021] As a preferred implementation in this embodiment, Figure 2 and Figure 3 As shown, the surface of the wear-resistant plate 2 is provided with a plurality of heat dissipation outer holes 201 at equal intervals in a circular shape, and the surface of the wear-resistant groove 3 is provided with heat dissipation inner holes 301 at positions corresponding to the heat dissipation outer holes 201. The cross-sectional shapes of the heat dissipation outer holes 201 and the heat dissipation inner holes 301 are both circular, and the diameter of the heat dissipation outer holes 201 is larger than the diameter of the heat dissipation inner holes 301, thereby achieving the purpose of ensuring the overall heat dissipation effect of the brake disc.

[0022] As a preferred implementation in this embodiment, Figure 1 As shown, the brake disc body 1 and the wear-resistant plate 2 are arranged coaxially, and the outer diameter of the brake disc body 1 is the same as the outer diameter of the wear-resistant plate 2, so that the peripheral side surfaces of the brake disc body 1 and the wear-resistant plate 2 are flush, achieving the purpose of ensuring the overall appearance of the brake disc body 1 and the wear-resistant plate 2 after assembly.

[0023] As a preferred implementation in this embodiment, Figure 1 As shown, a brake disc hub 6 is fixedly connected to the brake disc body 1, and a plurality of assembly holes 601 are provided in an annular shape at equal intervals on the surface of the brake disc hub 6, so as to achieve the purpose of assembling the brake disc hub 6 with the vehicle wheel hub.

During use, the vehicle's brake caliper clamps the wear-resistant plate 2 to generate braking force. During the later maintenance of the brake disc, if it is necessary to replace the severely worn wear-resistant plate 2, loosen the limiting bolt 401 on each anti-torsion plug block 4, so that the limiting bolt 401 is separated from the locking screw groove 501, and the wear-resistant plate 2 is removed from the two wear-resistant grooves 3 on the brake disc body 1 for replacement.
