[0003] However, the automobile brake discs currently used in the market have the following defects:

[0004] Firstly, most of the existing automobile brake discs are cast in one go by gray cast iron, and the gray cast iron has average wear resistance and high wear degree under long-term use, which seriously affects the overall service life of the automobile brake disc; secondly, the existing automobile brake discs all transfer heat to the heat dissipation cavity and use air convection to dissipate heat. This heat dissipation method has average heat dissipation effect, causing the temperature of the automobile brake disc to rise sharply in a short period of time and reducing the friction coefficient of the automobile brake disc, which seriously affects the braking effect of the automobile brake disc. Utility Model Content

[0005] The purpose of the utility model is to provide a highly wear-resistant automobile brake disc to solve the problem that the existing automobile brake discs mentioned in the above background technology are mostly made of gray cast iron cast in one go, and the gray cast iron has general wear resistance and high wear degree under long-term use, which seriously affects the overall service life of the automobile brake disc.

[0006] To achieve the above object, the utility model provides the following technical solution: a highly wear-resistant automobile brake disc, comprising:

[0007] Two high-wear-resistant brake pads, each of which comprises an aluminum alloy base layer, and each of which has a metal ceramic wear-resistant layer fixedly disposed on its outer surface;

[0008] One end of the two high-wear-resistant brake pads is evenly provided with a plurality of heat dissipation holes, and the other ends of the two high-wear-resistant brake pads are respectively contacted and connected with the two ends of the brake disc body, and the brake disc body includes two connecting disks, and the two connecting disks are fixedly connected by a plurality of heat dissipation fins, and one end of the two connecting disks is fixedly provided with a heat-conducting silicone sheet, and one end of the two heat-conducting silicone sheets is respectively contacted and connected with the other ends of the two high-wear-resistant brake pads.

[0009] As a preferred technical solution of the utility model, an L-shaped assembly ring is fixedly provided in the middle part of the two high-wear-resistant brake pads, one end of the two L-shaped assembly rings are threadedly connected to the two ends of eight assembly bolts respectively, and the middle parts of the eight assembly bolts are threadedly connected to one end of the two connecting plates and one end of the two thermal conductive silicone sheets in turn.

[0010] As a preferred technical solution of the utility model, two sides of the middle part of the eight assembly bolts are respectively fixedly connected to one end of two fixed assembly rings, and the two fixed assembly rings are fixedly arranged at the middle part and the bottom of the mounting tube body.

[0011] As a preferred technical solution of the utility model, the two high-wear-resistant brake pads are fixedly connected by an easily detachable connecting structure, and the easily detachable connecting structure includes four first connecting plates, and the middle parts of the bottom ends of the four first connecting plates are fixedly provided with first clamping blocks, and one ends of the four first clamping blocks are respectively connected to the middle parts of the top ends of the four second connecting plates through first clamping grooves.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By setting up high-wear-resistant brake pads, the high-wear-resistant brake pads are composed of an aluminum alloy base layer and a metal ceramic wear-resistant layer. The metal ceramic wear-resistant layer has ultra-high wear resistance, which can reduce the degree of wear of the automobile brake disc under long-term use, thereby effectively improving the service life of the automobile brake disc.

[0015] 2. By setting up high-wear-resistant brake pads, thermally conductive silicone sheets and heat sinks, the thermally conductive silicone sheets and heat dissipation holes can quickly transfer the heat on the high-wear-resistant brake pads to the heat sinks, and the heat sinks can quickly dissipate their own heat to the outside world. The heat dissipation effect is high, which can avoid the temperature of the automobile brake disc from rising sharply in a short period of time and reduce the friction coefficient of the automobile brake disc, thereby ensuring the braking effect of the automobile brake disc.

[0016] 3. By setting an L-shaped assembly ring, assembly bolts, fixed assembly ring and easy-to-disassemble connection structure, after the high-wear-resistant brake pad is used for a long time, the assembly bolts are loosened, and the second clamping block is pressed back into the hidden groove to separate the first clamping block from the first clamping groove. At this time, the high-wear-resistant brake pad can be removed from the brake disc. The operation is simple and convenient for later maintenance. After the braking effect of the brake disc is reduced, there is no need to replace the entire brake disc, only the high-wear-resistant brake pad needs to be replaced, which can effectively reduce costs.
