Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to a lightweight brake disc. Background Technique

[0002] Brake discs are classified into solid brake discs and ventilated discs according to their structures. A solid brake disc is a metal disc used for braking without any special structure. The ventilated disc is divided into two forms, namely the grooved disc and the drilled disc. The functions of these two treatment methods are to improve the cooling performance of the brake disc, reduce its thermal attenuation degree, and provide better braking ability.

[0003] Since most brake discs are made of metal and the metal has a large weight, this results in a large weight of the brake disc. This weight burden is particularly obvious during high-speed driving because it not only increases the overall mass of the vehicle but also affects the vehicle's power performance and fuel economy. The lightweight design can greatly improve the heat dissipation performance of the brake disc. Through the lightweight design, while ensuring the strength and wear resistance, the mass of the brake disc can be significantly reduced. Such a design can not only improve the heat dissipation ability of the brake disc itself but also enhance the response speed and stability of the entire braking system, thereby improving the safety performance of the vehicle. Content of the Utility Model

[0004] The purpose of the utility model is to provide a lightweight brake disc to solve the problems raised in the above background technique.

A pin 4 is inserted into the through hole 11 provided on the first brake disc 1 and the second brake disc 9. A fixing bolt 19 is provided in the pin 4. The pin 4 cooperates with the fixing bolt 19 to fix the second brake disc 9 on the side of the first brake disc 1 close to the installation flange 7.

[0022] Furthermore, a number of first installation holes 8 are provided on the installation flange 7 for installing the brake disc on an automobile.

[0023] Furthermore, chamfers 14 are provided at one end of several of the through holes 11 for accommodating the end portions of the dowel pins 4 and the fixing bolts 19, so as to avoid the protrusions of the end portions of the dowel pins 4 and the fixing bolts 19 from affecting braking.

[0024] Furthermore, a third card slot 13 is provided in the through hole 11, and a limit sleeve 17 is clamped inside the third card slot 13. The limit sleeve 17 is used to limit the distance between the first brake disc 1 and the second brake disc 9.

[0025] Furthermore, a threaded hole 18 is formed in the dowel pin 4, and grooves 6 are provided at the end portions of the fixing bolt 19 and the dowel pin 4. The fixing bolt 19 is threadedly connected to the dowel pin 4 through the threaded hole 18. By rotating the dowel pin 4 and the fixing bolt 19 through the grooves 6, they can be disassembled.

[0026] Furthermore, a first flow guide piece 3 and a second flow guide piece 20 are respectively clamped in the first card slot 10 and the second card slot 12. While providing support for the first brake disc 1 and the second brake disc 9, the first flow guide piece 3 and the second flow guide piece 20 are also used to guide air to flow through between the first brake disc 1 and the second brake disc 9 for heat dissipation.

[0027] Working principle: Before installing the brake disc, first clamp the first flow guide piece 3 and the second flow guide piece 20 in the first card slot 10 and the second card slot 12 respectively opened on the first brake disc 1, then clamp the limit sleeve 17 in the third card slot 13, then align the side of the second brake disc 9 with the first card slot 10, the second card slot 12 and the third card slot 13 with the first flow guide piece 3 and the second flow guide piece 20, and then clamp the first flow guide piece 3, the second flow guide piece 20 and the limit sleeve 17 in the first card slot 10, the second card slot 12 and the third card slot 13.
