Detailed Embodiments

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] As Figures 1 to 4 shown, the utility model provides a motor vehicle brake disc with high wear resistance, including: a mounting disc 1, a wear-resistant plate 2, and a mounting seat 3. The mounting disc 1 is of an overall circular structure, and two groups of mounting discs 1 are arranged side by side. The wear-resistant plate 2 is of an overall fan-shaped structure. The wear-resistant plates 2 are respectively arranged on the opposite sides of the two groups of mounting discs 1, and the wear-resistant plates 2 are distributed in a circular array on the mounting disc 1. The wear-resistant plates 2 on the same side are connected to each other to form a circular structure. The mounting seat 3 is arranged at the center of the mounting disc 1, and a number of mounting holes 31 are arranged in a circular array on the mounting seat 3. The mounting discs 1 are fixedly connected by connecting blocks 18. The connecting blocks 18 are distributed in a circular array, and ventilation channels are arranged between adjacent connecting blocks 18.

[0018] The wear-resistant plates 2 are arranged on both sides of the mounting disc 1, form a circular structure through mutual assembly, and can be disassembled and replaced to meet the use requirements; the whole is installed and fixed through the mounting seat 3.

[0019] Among them, a number of fixing grooves 11 are arranged on the surface of the mounting disc 1, and fixing pins 13 are installed in the fixing grooves 11. Corresponding fixing blocks 21 are arranged on the wear-resistant plate 2, fixing holes 23 are arranged on the fixing blocks 21, and the fixing pins 13 are correspondingly inserted into the fixing holes 23. Locking holes 17 are arranged on the periphery of the mounting disc 1, and locking screws 4 are installed in the locking holes 17. The pin rod 41 of the locking screw 4 abuts against the fixing block 21 and presses the fixing block 21 against the fixing pin 13.

[0020] By tightening the locking screw 4 in the locking hole 17, the pin rod 41 of the locking screw 4 abuts against the fixing block 21 and pushes it in the direction of the fixing pin 13. Finally, the fixing block 21 is sleeved on the fixing pin 13 through the fixing hole 23 to achieve clamping; multiple wear-resistant plates 2 are assembled with each other to achieve clamping; when disassembling, the locking screw 4 is removed.

[0021] Among them, auxiliary grooves 12 are arranged on both sides of the fixing groove 11, and auxiliary pins 14 are arranged in the auxiliary grooves 12. Corresponding auxiliary blocks 22 are arranged on the wear-resistant plate 2, auxiliary holes 24 are arranged on the auxiliary blocks 22, and the auxiliary pins 14 are correspondingly inserted into the auxiliary holes 24.

[0022] The auxiliary groove 12 provides an additional auxiliary pin 14 for inserting into the auxiliary hole 24 on the auxiliary block 22, providing more fixing points to ensure the stability of the installation of the wear-resistant plate 2.

[0023] Among them, an annular elastic piece 15 is sleeved on the auxiliary pin 14, and a spring 16 is arranged between the elastic piece 15 and the auxiliary groove 12. The auxiliary block 22 is sleeved on the auxiliary pin 14 and abuts against the elastic piece 15, compressing the spring 16.

[0024] The spring 16 is in a compressed state after the wear-resistant plate 2 is installed. In this way, after disassembly, the spring 16 is restored to eject the fixing block 21, thus facilitating the disassembly of the wear-resistant plate 2.

[0025] Wherein, a clamping groove 42 is provided on the end face of the locking screw 4, and the clamping groove 42 is set as a regular hexagonal counterbore.

[0026] The setting of the clamping groove 42 facilitates the use of a hexagonal wrench to turn the locking screw 4.
