What problems will occur if the friction coefficient of the friction sheet is too high or too low?
The friction coefficient of the friction plate is too high or too low, there will be some problems, will affect the braking performance of the car. The following Hanleke friction sheet company will explain to you what problems will occur if the friction coefficient of the friction sheet is too high or too low.
First of all, let's look at what will happen if the friction coefficient of the friction sheet is too high or too low.
1. The friction coefficient of the brake friction disc is too low
When the car needs emergency braking at high speed, the friction coefficient is too low, there will be insensitive braking phenomenon.
2. The friction coefficient of the brake friction disc is too high
If the friction coefficient of the brake friction plate is too high, the phenomenon of tire locking will occur, and then cause the vehicle to throw the tail and skid, which poses a serious threat to driving safety.
In fact, according to the national standard, the appropriate working temperature of the brake friction disc or friction block is 100~350 ° C. However, there are many inferior brake friction pads/friction blocks when the temperature reaches 250 ° C, the friction coefficient will drop sharply, and the brake will completely fail at this time. In general, according to SAE standards, brake friction plate manufacturers will choose FF grade rating coefficient, that is, the friction rating coefficient is 0.35~0.45.
