The clutch disc is a composite material with friction as its main function and structural performance requirements. Tractor friction materials are mainly used to manufacture brake friction discs and clutch discs. These friction materials mainly use asbestos-based friction materials. With the increasing requirements for environmental protection and safety, semi-metal friction materials, composite fiber friction materials, and ceramic fiber friction materials have gradually appeared.
Since friction materials are mainly used in the manufacture of brake train and drive train parts on tractors, a sufficiently high and stable friction coefficient and good wear resistance are required. So how do we judge the performance of the clutch friction disc? In response to this problem, the tractor clutch manufacturer gave us a detailed explanation.
1. Appropriate friction coefficient
The friction coefficient is the most basic parameter of the friction material, which determines the basic braking torque of the brake disc. The national standard strictly requires manufacturers to indicate the coefficient of friction on the packaging. The friction coefficient must be appropriate. Too high will cause wheel lock, direction loss and burning during braking, while too low will result in too long braking distance.
2. Reliable security
Brake discs will generate instantaneous high temperature when braking, especially at high speed or emergency braking. At high temperature, the friction coefficient of the friction disc will decrease, which is called thermal recession. The level of thermal decay determines the safety in high temperature conditions and emergency braking.
