Product Description
The brake disc is simply a round plate, which also rotates when the car travels The brake calliper clamps the brake disc to generate braking force. When stepping on the brake, it clamps the brake disc to slow down or stop Brake disc has good braking effect and is easier to maintain than drum brake.
The brake disc is made of gray cast iron 250 made in China for short HT250, which is equivalent to G3000 made in the United States The requirements of the three main elements of chemical composition are: C: 3.1 ↓ 3.4 Si: 1.9 ↓ 2.3 Mn: 0.6 ↓ 0.9 Mechanical properties: Tensile strength > = 206MPa, bending strength > = 1000MPa, deflection > = 5.1 mm. Hardness requirements are between 187~241 HBS.
Brake discs are divided into solid brake discs and ventilation discs according to structure A solid brake disc is a metal disc used for braking and has no special structure The ventilated discs are divided into two types: scribed discs and perforated discs. The two treatments can improve the cooling performance of brake discs, and their thermal attenuation degree can provide better braking ability.
Brake discs can be divided into carbon fiber ceramic brake discs and metal brake discs according to different materials. However, due to the high manufacturing cost and poor braking force at low temperature, carbon fiber ceramic brake discs are still not selected by most vehicles despite their excellent thermal attenuation resistance In order to resist thermal attenuation ability, some manufacturers also carry out carbon fiber treatment on metal brake discs to improve their ability in this respect and avoid the problem of poor low temperature performance of carbon fiber ceramic materials.
