Classification and braking effect of brake disc

Disc brake disc is divided into solid disc (single disc) and air duct disc (double disc), perforated ventilation disc, scribed ventilation disc, floating ventilation disc and ceramic ventilation disc. Solid disks are easy for us to understand. Frankly, it is solid. As the name suggests, the air duct board has ventilation effect. From the appearance, it has many holes leading to the center of the circle on the circumference, which is called air duct. When the vehicle is running, the air passes through the air duct to achieve the purpose of heat dissipation, which is better than the solid heat dissipation effect.

Advantages of floating brake disc

The advantage of floating brake disc is that the vehicle produces a large amount of calorific value in the process of high-intensity braking, which makes the physical phenomenon of thermal expansion and cold contraction of brake disc deform and affect the normal braking effect, which is also one of the main factors of heat attenuation. The floating brake disc is not directly locked with the central disc, or there is some small space between the floating part and the disc. After locking, the disc surface and the central disc still have a gap and can shake left and right, but the central disc and disc can be fixed. This design can solve the problem of overheating and shaking. The floating brake disc is more stable than the two-piece disc.
