Background

On the field of FSC, there are many factors that affect the speed of a racing car, and the performance of the braking system is an important part of the safety of the racing car for delaying braking and driver. The brake disc is one of the most important parts of a braking system, and is also an important target for optimizing and upgrading each motorcade over the years, the radial size of the brake disc is mainly limited by the size of a rim, and the axial thickness of the brake disc is also limited by the size of a wheel edge, so that the main optimization direction in the field is an optimized punching mode, a better heat dissipation condition is obtained on the premise of ensuring the braking torque, and the purpose of reducing the unsprung mass is achieved.

The common axial punching brake disc of the FSC racing car, namely, the through holes are punched on the surface of the brake disc along the diameter direction, is the most common brake disc form on the FSC racing field, is similar to the design of ventilation discs of most passenger cars, although the design has good heat dissipation effect, the cost is extremely high, the requirements on the sizes of a rim and a wheel edge are very strict, the universality is not realized, and the brake disc of the conventional FSC racing car is widely used, but the following problems exist.

1. The existing FSC brake disc is large in size, thick in size and large in mass, so that the rotary inertia is larger, more heat energy is generated during braking, the unsprung mass of a vehicle is increased, the vehicle is not flexible to control, and meanwhile, the phenomenon of heat fading is easier to generate under the condition of intense driving such as competition.

2. The existing FSC brake disc punching mode is mostly common radial punching, the number of hole sites is small, the heat dissipation efficiency is low, heat is easily transferred to a tire while the braking effect is influenced, and the tire abrasion is accelerated. Meanwhile, when the automobile runs in rainy days, a water film is easily formed on the surface of the brake disc, and when the automobile runs in sunny days, an air film is easily generated, so that the braking effect is weakened.

There is therefore a need for improvements to existing FSC racing brake discs that improve the quality of the FSC racing brake discs.
