The brake disc is fixed to the wheel through the mounting hole and rotates with the wheel. When the vehicle brakes while driving, the brake caliper clamps the brake disc to slow down or stop the vehicle. As a core component in the automobile braking system, the performance of the brake disc is directly related to the overall braking performance of the vehicle. A traditional brake disc includes a cylindrical barrel and an annular disc connected to the barrel mouth of the barrel.

In response to the above problems, a new automobile brake disc structure is proposed for improvement and upgrading. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, purposes and effects achieved by the present application easy to understand, the present application will be further described below in conjunction with specific embodiments.

[0023] As Figure 1 - Figure 4 The present application provides a novel brake disc structure of an automobile, which comprises a brake disc body 1, a brake caliper 2 is arranged on the outer wall of the brake disc body 1, a fixed frame 3 is arranged in the brake caliper 2, a brake fluid pipe 4 is arranged on the outer wall of the fixed frame 3, positioning plates 5 are fixedly arranged on both sides of the inner wall of the fixed frame 3, fixed rods 51 are symmetrically arranged on the outer walls of the two positioning plates 5, support plate layers 52 are arranged on the outer sides of the two positioning plates 5, heat dissipation plate layers 55 are arranged on the outer sides of the support plate layers 52, wear-resistant plate layers 57 are arranged on the outer sides of the heat dissipation plate layers 55, and the sizes of the support plate layers 52, the heat dissipation plate layers 55 and the wear-resistant plate layers 57 are the same.

[0024] Preferably, four hexagonal knobs 21 are provided on both sides of the outer wall of the brake caliper 2, and the outer walls of the hexagonal knobs 21 are fixedly connected with screws 22, two groups of slots 23 are opened inside the fixing frame 3, and mounting gaskets 24 are provided on both sides of the inner wall of the fixing frame 3 at the slots 23, wherein the outer walls of two groups of screws 22 are threadedly connected to the inside of the slots 23 and the extended ends are connected to the outer wall of the brake caliper 2, and the other two groups of screws 22 are threadedly connected to the inside of the brake caliper 2, which facilitates the disassembly and assembly of the fixing frame 3 and the brake caliper 2 and facilitates their maintenance.

[0025] Preferably, a reinforcing rib 53 is fixedly provided on the rear side of the outer wall of the support plate layer 52, and a plurality of weight-reducing holes 54 are opened on the outer wall of the support plate layer 52, the reinforcing ribs 53 are distributed in a ring shape, a plurality of heat dissipation grooves 56 are opened inside the heat dissipation plate layer 55, the heat dissipation grooves 56 are distributed in an inclined shape, and the cross-section of the heat dissipation grooves 56 adopts a "trapezoidal" structure, a plurality of friction convex balls 58 are provided on the outer wall of the wear-resistant plate layer 57, and mounting holes 59 are opened on both sides of the support plate layer 52, the heat dissipation plate layer 55 and the wear-resistant plate layer 57, and the fixing rod 51 passes through the mounting hole 59.

[0026] By arranging multiple friction convex balls 58 on the wear-resistant plate layer 57, which are composed of mutually intersecting grooves and hemispherical protrusions, the friction between the brake pad and the brake disc is increased, and the braking effect is improved. The wear-resistant plate layer 57 is made of high-performance carbon ceramic composite materials, which can effectively extend the service life of the brake disc and have good high temperature resistance. The heat dissipation groove 56 is set to be inclined from the inner edge to the outer edge of the brake disc, and the cross-section is trapezoidal, narrow inside and wide outside. When the brake disc rotates, the centrifugal force causes cold air to be sucked into the heat dissipation channel from the inner edge. After the air exchanges heat with the friction layer and the heat dissipation layer in the channel, it is discharged at high speed from the outer edge, forming an air-cooled heat dissipation effect. The inclined design increases the air flow path and improves the heat dissipation effect. Then, high-strength alloy steel is selected for the support plate layer 52. This material can meet the strength and rigidity requirements of the brake disc, making the brake disc relatively stable when braking.

[0027] The principle and process of use of the present invention are as follows: first, the brake caliper 2 is set on the brake disc by rotating the screw 22 using the hexagonal knob 21, and then the fixing bracket 3 is installed on the brake caliper 2 by rotating the screw 22 using the hexagonal knob 21. When it is installed using the mounting gasket 24, it is relatively tight, and vice versa, it is easy to disassemble, which makes it easy to disassemble and assemble the brake caliper 2 and the fixing bracket 3, and convenient for maintenance. The brake disc rotates at high speed through the wheel. When the driver brakes it, the brake disc contacts the wear-resistant plate layer 57 on the fixing bracket 3, and during the braking process, it bears the responsibility of transmitting friction. The heat generated by the friction is then transferred to the interior of the heat dissipation plate layer 55. The light aluminum alloy material on the surface of the heat dissipation plate layer 55 is used to quickly conduct the heat away due to its excellent thermal conductivity, thereby achieving efficient heat dissipation and avoiding brake degradation due to overheating. A support plate layer 52 is then provided to provide the necessary strength and rigidity for the entire brake disc. A plurality of irregular weight-reducing holes 54 and reinforcing ribs 53 are provided on the surface of the support plate layer 52 to improve the stability of the overall structure. Finally, the fixing rod 51 is used to fix and limit the support plate layer 52 to improve the safety of the brake disc when braking.
