The scallop disc in the car is also the brake disc, which is one of the important components in the car braking system. It is a device that generates braking force through friction and is often used in cars and other mechanical equipment. Automotive scallop discs are usually made of materials such as cast iron, steel, and ceramics, and have the characteristics of wear resistance and good heat dissipation.

The function of the car scallop disc is to transmit the friction force to the ground through the tire during braking, so that the car can be slowed down or stopped. When braking, the brake caliper presses the scallop disc, friction generates heat, and the heat is dissipated through the heat sink on the surface of the scallop disc, so that the scallop disc and brake caliper cool down, ensuring the normal operation of the braking system.

Material

1. Cast iron

One of the most commonly used car scallop disc materials because of its relatively cheap price, stable performance and good heat dissipation performance. But the disadvantage is that it is heavier, which increases the overall weight of the vehicle and is not suitable for racing vehicles.

2. Steel

Lighter than cast iron, it is therefore suitable for vehicles that need to run at high speeds, such as racing cars and performance cars. High-strength steel and carbide steel are two commonly used steels.

3. Ceramics

One of the latest automotive scallop disc materials, it has very low thermal conductivity and mass, so it can provide better heat dissipation performance and shorter braking distance. The downside of ceramic discs is that they are very expensive, are fragile and need to be handled with great care.

4. Carbon fiber

The material is light and strong, has excellent wear resistance and high temperature performance, so it is suitable for racing cars and high-performance cars, but it is very expensive.

5. Titanium alloy

The material is relatively light, but has high strength and good corrosion resistance. This material is also great for making car scallop discs. But the price is also very expensive.

In addition to the above materials, there are also some special car scallop disc materials, such as carbon fiber and titanium alloy. These materials are often used in high-end racing cars because they are very light and offer great strength and abrasion resistance, but they are very expensive.

Structure

1. ​​​​​​​​​​​​​​​​

The main part of the scallop disc is usually made of high-strength metal alloy materials such as titanium alloy and nickel-based alloy. The size and shape of the pan varies by application and manufacturer, with larger aircraft and racing cars often requiring larger pans to improve their braking efficiency and performance.

2. Braking surface

There will be a layer of braking surface on both sides of the pan body, which is used to generate friction with the brake pads to slow down or stop the rotation of the wheel or aircraft wheel. Braking surfaces are usually made of high-temperature and wear-resistant carbon-ceramic materials or metal-ceramic composite materials.

3. Cooling fins

Radiating fins are located on the braking surface on both sides of the pan body to increase the surface area of ​​the pan body to improve heat dissipation efficiency. Fins are usually arc-shaped, and the number and shape vary by manufacturer and application.

4. Center hole

The center hole is located in the center of the pan body and is used to mount the scallop disc on the hub of a wheel or aircraft wheel. The size and shape of the center hole will also vary by application and manufacturer.

5. Threaded hole

Threaded holes are located on the edge of the plate for securing components such as brake pads and brakes. The number and location of the threaded holes also vary by application and manufacturer.

Size

Size and shape will vary by vehicle type, make and model. Most car brake discs are between 10 inches and 16 inches in diameter and between 0.25 inches and 1 inch thick.

Light vehicles typically use smaller pucks, while heavy vehicles such as trucks and buses require larger pucks for higher loads and inertia. The number and shape of the disc’s grooves also vary by vehicle type and manufacturer, and different groove designs can affect the disc’s cooling performance and braking efficiency. Therefore, when replacing or upgrading the brake disc, it is necessary to select the appropriate size and design of the brake disc according to the vehicle type and needs to avoid danger.

Application

An important part of a car’s braking system, which slows or stops the rotation of the wheels by creating friction with the brake pads. The main application field of scallop discs is the automotive braking system to improve the braking efficiency and safety performance of the vehicle.

In a car braking system, there are usually two scalloped discs, each of which is combined with a brake pad to form a brake, mounted on the wheel axle. When the driver depresses the brake pedal, the pads inside the brakes come into contact with the scallop discs and create friction that slows or stops the wheels from spinning. Because the friction between the brake pad and the scallop disc will generate high temperature, the scallop disc usually adopts high-strength materials and heat dissipation structure to improve its durability and heat dissipation efficiency.

In addition to applications in automotive braking systems, scallop discs can also be used in other industrial fields, such as railway and aircraft braking systems. Additionally, some high-performance racing vehicles feature large scalloped discs to improve their braking efficiency and performance.

Conclusion

It is very important to choose a car scallop disc suitable for your vehicle. A good scallop disc should have the characteristics of high temperature resistance, wear resistance, and good heat dissipation. At the same time, when installing the car scallop disc, it is necessary to ensure that it is firmly connected to the hub and the position of the brake caliper is correct.

When using car scallop discs, pay attention to maintenance, regularly check the wear of brake pads and scallop discs, and replace them in time. In addition, avoid pressing the brake pedal for a long time, so as not to overheat the scallop disc and cause deformation or damage.
