The comfort performance of the self feeding mixer is directly reflected in the braking feeling of the car, such as noise, dust, smoke, smoke, smell and so on. With the improvement of people's living standards, the comfort is increased, which has basically become an index to meet the safety

摩擦系数是摩擦材料的基本参数，决定了基本制动的制动力矩。标准要求制造商指定包装上的摩擦系数。摩擦系数必须适当，太高会导致制动过程中的车轮保持死亡，方向失控和燃烧膜，过低的刹车距离太长。 当制动时，小的搅拌器制动能产生瞬时的高温，特别是在高速或紧急制动时。在高温下，摩擦板摩擦系数减小，称为热衰减。热衰减决定了高温状态和紧急制动的安全性。
              

Friction coefficient is the basic parameter of friction material, which determines the braking torque of basic braking. The standard requires the manufacturer to specify the coefficient of friction on the package. The friction coefficient must be appropriate, too high will cause the wheel to stay dead during braking, direction out of control and burning film, too low braking distance is too long. When braking, small agitator braking can produce instantaneous high temperature, especially in high speed or emergency braking. At high temperature, the friction coefficient of friction plate decreases, which is called thermal attenuation. Thermal attenuation determines the safety of high temperature and emergency braking.
