Description

Technical Field

[0001] This utility model relates to the field of brake disc technology, and in particular to a lightweight, low-carbon brake disc for automobiles. Background Technology

[0002] Brake discs are an important component of a car's braking system. Their main function is to slow down or stop the vehicle through friction. When a vehicle is moving, friction is generated between the brake discs and brake pads, which converts the vehicle's kinetic energy into heat energy and reduces the vehicle's speed. Brake discs are usually mounted on the vehicle's wheel axles and work together with brake pads, brake calipers, and other components to form a complete braking system.

[0003] Prolonged operation of brake discs can cause the overall temperature of the brake discs to rise, which can affect the response speed and efficiency of the braking system. Furthermore, excessively high temperatures can also pose a fire hazard.

[0004] Therefore, those skilled in the art provide a lightweight, low-carbon brake disc for automobiles to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lightweight, low-carbon brake disc for automobiles. Through the structure of venting grooves and reinforcing ribs, it reduces material usage while ensuring strength, thereby further reducing weight.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A lightweight, low-carbon brake disc for automobiles includes a first friction disc and a second friction disc. Strip-shaped ribs are fixedly connected to the outer walls of the first and second friction discs on their adjacent sides. The strip-shaped ribs are arc-shaped. The disc bodies of the first and second friction discs are provided with multiple ventilation grooves. The multiple ventilation grooves are respectively connected to the airflow channel formed by the multiple strip-shaped ribs. The ends of the strip-shaped ribs away from the inner walls of the first and second friction discs protrude from the outer walls of the first and second friction discs. The above technical solution uses the arc design of the strip ribs to form a directional airflow channel. After connecting with the ventilation groove, it generates a centrifugal ventilation effect when the brake disc rotates, which accelerates the airflow, quickly removes frictional heat, and avoids heat decay.

[0007] Furthermore, all the ventilation grooves are designed in an arc shape; The above technical solution allows for better adaptation of the airflow channels composed of strip stiffeners with an arc-shaped design, thus facilitating heat dissipation.

[0008] Furthermore, both the first friction disc and the second friction disc are made of aluminum alloy; The above technical solution can effectively reduce the overall weight of the brake disc.

[0009] Furthermore, an installation disc is fixedly connected to the middle of the outer wall of the front end of the first friction disc; The above technical solution allows for convenient and efficient installation via the provided installation disk.

[0010] Furthermore, a plurality of mounting threaded holes are provided at the edge of the outer wall of the front end of the mounting plate; The above technical solution makes it easier to install the brake disc onto small vehicles.

[0011] This utility model has the following beneficial effects: 1. The present invention proposes a lightweight, low-carbon brake disc for automobiles. By using strip-shaped ribs arranged on the side of the first and second friction discs close to each other, the brake disc is installed clockwise. When the wheel rotates, the strip-shaped ribs protruding from the first and second friction discs bring in external airflow, and then the heat of the first and second friction discs is carried away through the ventilation grooves on both sides. This avoids the problem of reduced braking efficiency due to overheating of the brake disc during prolonged braking. Attached Figure Description

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] One specific embodiment of this utility model is provided: Reference Figure 1 , Figure 2 and Figure 4 : A lightweight, low-carbon brake disc for automobiles includes a first friction disc 1 and a second friction disc 5. Strip-shaped ribs 4 are fixedly connected to the outer walls of the first friction disc 1 and the second friction disc 5 on their adjacent sides. The strip-shaped ribs 4 are arc-shaped. The disc bodies of the first friction disc 1 and the second friction disc 5 are provided with multiple ventilation grooves 2. The multiple ventilation grooves 2 are respectively connected to the airflow channel formed by the multiple strip-shaped ribs 4. The end of the strip-shaped ribs 4 away from the inner wall of the first friction disc 1 and the second friction disc 5 protrudes from the outer wall of the first friction disc 1 and the second friction disc 5. The arc-shaped design of the strip rib plate 4 forms a directional airflow channel, which, after connecting with the ventilation groove 2, generates a centrifugal ventilation effect when the brake disc rotates, accelerating airflow, quickly carrying away frictional heat, and avoiding heat decay.

[0016] Reference Figure 2 and Figure 4 : The ventilation grooves 2 are all arc-shaped, which can better adapt to the airflow channel composed of the arc-shaped strip ribs 4, thus facilitating heat dissipation. The first friction disc 1 and the second friction disc 5 are both made of aluminum alloy, which can effectively reduce the overall weight of the brake disc.

[0017] Reference Figure 1 : A mounting plate 3 is fixedly connected to the middle of the outer wall of the front end of the first friction disc 1. The mounting plate 3 can be used to facilitate installation. Multiple mounting threaded holes are provided on the edge of the outer wall of the front end of the mounting plate 3, so that the brake disc can be installed on a small vehicle more conveniently.

[0018] Working principle: The brake pad is installed on the vehicle clockwise using the mounting disc 3, so that the protruding parts of the strip rib plate 4 are all facing downwards. Then the brake caliper is installed. When the vehicle is under friction braking for a long time, the rolling of the brake disc drives the strip rib plate 4 to rotate, thereby causing the protruding parts of the strip rib plate 4 to draw airflow into the interior, and then the airflow is discharged through the vent groove 2, thereby carrying away the heat of the first friction disc 1 and the second friction disc 5.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
