1. Appropriate friction coefficient
The friction coefficient is the most basic parameter of the friction material, which determines the basic torque of the brake. The national standard strictly requires Transmission Hard Parts manufacturers to indicate the friction coefficient on the packaging. If the friction coefficient is too high, the wheels will lock, the direction will be out of control, and the disc will burn out. If the friction coefficient is too low, the braking distance will be too long.
2. Reliable safety
Transmission Pulley will generate instantaneous high temperatures when braking, especially at high speeds or emergency braking. The friction coefficient of the friction plate will decrease at high temperatures, which is called thermal decay. The safety of high-temperature emergency braking depends on the degree of thermal decay.
3. Satisfactory comfort
Comfort is a direct reflection of friction performance, including braking feel, noise, dust, smoke, odor, etc. With the increase of private cars and the improvement of people's living standards, comfort has become an important indicator of friction plates under the basic premise of safety. In the comfort index, car owners are often most concerned about the noise of Transmission Pulley. In fact, noise is also the most difficult problem for all friction material manufacturers to solve. Noise is caused by abnormal friction between friction plates. The cause of noise is very complicated. Braking force, brake disc temperature, vehicle speed and weather conditions may be the cause of the noise.
In addition, the causes of the noise are different in the three different stages of brake initiation, brake application and brake release. If the noise frequency is between 0 Hz and 500 Hz, it will not be felt in the car, but if it exceeds 1500 Hz, the owner can clearly feel the brake noise.
