Vehicles break can be divided into disc brake and drum brake. From the principle of disc brake analysis and raw data, based on the brake force analys is to determine the braking torque, friction disc size, pedal power and manipulation. From analysis the brake structure, design the structure of the friction disc system, pressure plate structure and the structure of the spring brake system and manipulation systems. And accordance with the design of the brake requirements of the involute spline, select the type of rectangular spline and school nuclear strength of the spline, the spline result is enough intensity. The design of the brake disc in line with the theoretical requirements, to ensure a moving car in the braking and emergency braking, and can ensure safe braking ramp. Therefore, reach the purpose of ensure the drivers traffic safety.
