Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a two-piece brake disc. Background Art

[0002] Disc brake discs (rotors) are divided into solid discs (single-piece discs) and air duct discs (two-piece discs). Solid discs are relatively easy to understand. Simply put, they are solid. As the name implies, air duct discs have the function of ventilation. Looking from the outside, it has many holes leading to the center of the circle on the circumference, which are called air ducts. When the vehicle is running, air convection occurs through the air ducts to achieve the purpose of heat dissipation, and the heat dissipation effect is much better than that of solid discs.

[0003] The single-piece brake disc is a solid brake disc, with relatively poor heat dissipation effect. Moreover, once it is damaged during use, it will cause the brake to fail, and it is not easy to detect when the temperature is too high, seriously affecting driving safety.

[0004] Therefore, it is particularly important to design a two-piece brake disc to change the above technical defects and improve the overall practicability. Content of the Utility Model

[0005] The purpose of the utility model is to provide a two-piece brake disc to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A two-piece brake disc includes a rotor and a connecting piece. The rotor is connected to a first brake disc, the first brake disc is connected to a second brake disc, a brake caliper is arranged outside the first brake disc and the second brake disc, a connecting piece is arranged between the first brake disc and the second brake disc, and a plurality of the connecting pieces are arranged in a turbine shape.

[0008] As a preferred scheme of the utility model, the rotor is connected to the first brake disc through semi-floating screws.

[0009] As a preferred scheme of the utility model, a layer of anti-corrosion paint is coated on the surfaces of the first brake disc and the second brake disc, a plurality of heat dissipation holes are arranged on the surfaces of the first brake disc and the second brake disc, each heat dissipation hole is in a honeycomb shape, and a thermal conductive graphite sheet is arranged along the edge inside the heat dissipation hole.

[0010] As a preferred scheme of the utility model, scribing lines for increasing the friction coefficient are arranged on the surfaces of the first brake disc and the second brake disc.

[0011] As a preferred scheme of the utility model, three groups of temperature sensors are arranged on one side of the first brake disc, and a layer of temperature-sensitive color-changing paint is coated on the rotor.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. In the present utility model, by providing a double-disc brake disc, using the structure of the first brake disc, the second brake disc, the rotor, and the temperature sensor, and connecting them with semi-floating screws, it avoids the thermal expansion and contraction between the rotor and the brake disc from falling off. At the same time, the turbine-shaped connecting piece enhances the heat dissipation effect. The scoring is used to increase the friction coefficient between the brake caliper and the brake disc for effective braking. Meanwhile, the heat dissipation holes provided facilitate the heat dissipation of the brake disc. Combining three groups of temperature sensors to divide different temperature ranges and display them on the dashboard, and different temperatures cause the rotor to show different colors, enabling more intuitive observation of the changes in the brake disc. This solves the problems of the single-piece brake disc being a solid brake disc with poor heat dissipation effect, and once it is damaged during use, it will cause the brake to fail, and it is not easy to detect when the temperature is too high, seriously affecting driving safety.

A number of connecting pieces are arranged in a turbine shape. There is a certain amount of clearance left when connecting the rotor 1 and the first brake disc 101 using semi-floating screws to prevent disengagement at high temperatures. The number of turbine-shaped connecting pieces between the first brake disc 101 and the second brake disc 102 enhances the heat dissipation effect. Grooves are used to increase the friction coefficient between the brake caliper 103 and the brake disc for effective braking. At the same time, the heat dissipation holes opened facilitate the heat dissipation of the brake disc.
