Description

Technical Field

[0001] This utility model relates to the field of braking system technology, specifically a brake disc assembly with stable positioning. Background Technology

[0002] Brake discs are an important component of a car's braking system, primarily used to slow or stop the vehicle. Early automobiles used wooden rims or metal wheels, relying mainly on friction for braking. Drivers typically slowed the vehicle by pulling the brake cable to directly contact the tires or axle. With advancements in automotive technology, particularly in the early 20th century, hydraulic braking systems became increasingly common, improving braking efficiency and stability.

[0003] The design of modern brake discs gradually took shape in the early 20th century. In 1915, Irish engineer Francis Hopkins invented the first true brake disc system. Compared to traditional drum brakes, disc brakes offer better heat dissipation and higher braking efficiency. With the development of materials science, the materials used to manufacture brake discs have also undergone numerous innovations. From the initial cast iron to the commonly used carbon ceramics and composite materials, these material upgrades have made braking performance more reliable and more wear-resistant.

[0004] Brake disc assemblies are the core components of disc brake systems, and their positioning stability directly determines braking accuracy and driving safety. However, most existing brake disc assemblies are positioned using a single bolt. Under the centrifugal force and impact force generated by high-speed rotation and high-frequency braking, problems such as increased positioning gaps and coaxiality deviations can easily occur, leading to brake vibration and uneven brake pad wear. Therefore, those skilled in the art have provided a brake disc assembly with stable positioning to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a brake disc assembly with stable positioning to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A brake disc assembly with stable positioning includes a brake disc, heat dissipation recesses, stepped discs, mounting threaded holes, a mounting surface, black electrophoretic coating, wear-resistant coating, corrosion-resistant coating, heat-resistant coating, and manufacturer markings. The stepped discs are integrally welded and fixed to the inner periphery of the brake disc. Each stepped disc has a mounting threaded hole at the center of its front end. The front end of the brake disc is the mounting surface, and there are four stepped discs and four mounting threaded holes. The inner periphery of the brake disc is integrally welded and fixed to the four stepped discs to form a radial positioning support structure. Each stepped disc has a mounting threaded hole at the center of its front end. The four mounting threaded holes are evenly distributed along the circumference of the brake disc. The front end of the brake disc is the mounting surface for fitting and engaging with the tire bolt.

[0008] As a further embodiment of this utility model: a plurality of heat dissipation recesses are provided around the front end periphery of the brake disc, and the heat dissipation recesses are evenly arranged along the circumference of the brake disc.

[0009] As a further improvement of this utility model, the outer surface of the brake disc is uniformly coated with a black electrophoretic coating.

[0010] As a further embodiment of this utility model: the black electrophoretic coating is uniformly applied to the outer surface of the brake disc, covering it with a wear-resistant coating, a corrosion-resistant coating, and a heat-resistant coating, with each coating being uniformly applied and covered.

[0011] As a further improvement of this utility model, the lower right corner of the stepped plate is etched with the manufacturer's logo.

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

[0013] 1. The stepped disc is welded to the inner perimeter of the brake disc, forming a single piece. The front end of the brake disc connects to one side of the tire thread rod via a mounting surface, featuring a flat surface and precise dimensions to ensure installation accuracy and reliability. The brake disc is tightly fitted onto the tire thread rod via threaded holes at the center of the front end of the stepped disc. Tightening the mounting nut allows the brake disc to be installed on the tire. The stepped disc's structural design provides multiple mounting planes and positioning references, enabling the brake disc to be accurately installed in the designated position and remain stable during braking. This ensures the accuracy and stability of the brake disc installation, guaranteeing even contact between the brake disc and brake pads during braking, improving braking performance and extending the brake disc's lifespan. It also achieves a secure connection between the brake disc and other components, allowing the brake disc to maintain a stable position during vehicle operation and ensuring the normal operation of the braking system.

[0014] 2. The heat dissipation recesses are located on the front periphery of the brake disc. The presence of the heat dissipation recesses allows air to form good convection on the surface and inside of the brake disc. Hot air is discharged from the heat dissipation recesses, and cold air is continuously replenished, thereby accelerating the dissipation of heat. This effectively prevents the braking system from overheating, ensures stable braking performance, avoids brake disc deformation or loss of braking ability due to overheating, and improves the reliability and safety of the braking system.

[0015] 3. The black electrophoretic coating is mainly used to improve the corrosion resistance and appearance of the brake discs. The wear-resistant, corrosion-resistant, and heat-resistant coatings further enhance the specific performance of the brake discs based on the black electrophoretic coating. The wear-resistant coating reduces friction and wear between the brake disc and brake pads, extending the brake disc's service life. The corrosion-resistant coating enhances the brake disc's resistance to corrosive media such as water and salt, preventing rust and corrosion. The heat-resistant coating maintains the structural stability and performance of the brake disc in high-temperature environments, preventing deformation or performance degradation due to high temperatures. These improvements enhance the overall performance of the brake discs, extend their service life, reduce maintenance costs, and ensure reliable operation in various harsh environments, thereby improving vehicle safety and reliability.

[0016] 4. The lower right corner of the stepped brake disc is etched with the manufacturer's logo. The manufacturer's logo is etched onto the surface of the stepped brake disc to identify the manufacturer, model, production date, and other information of the brake disc. This allows users to understand relevant information about the brake disc during purchase and use, facilitates quality traceability and after-sales service, and also helps prevent the circulation of counterfeit and substandard products, protecting the legitimate rights and interests of users.
