The influence of the friction coefficient of the brake friction plate on the braking
There are many customers who will have many questions about the coefficient of friction in the process of developing the brake friction plate in cooperation with our company. Here, the Hualong friction material engineer has made a professional answer to this:
If the friction coefficient of the brake pads is too high or too low, it will affect the braking performance of the car. Especially when the car needs emergency braking during high-speed driving, if the friction coefficient is too low, the braking will be insensitive, and if the friction coefficient is too high, the tire will lock up, which will cause the vehicle to drift and slip, which will affect the driving safety. serious threat.
According to the national standard, the suitable working temperature of the friction plate is 100～350℃. However, when the temperature of many inferior friction plates reaches 250 °C, the friction coefficient will drop sharply, and the braking will fail completely at this time. Generally speaking, according to the SAE standard, the friction plate manufacturers will use the FF rated coefficient, that is, the friction rated coefficient is 0.35 to 0.45.
