In the configuration of the vehicle, the brake is mainly to ensure the safety of the vehicle in the face of emergencies. It is particularly important for the special vehicle such as cement self loading mixer. The basic brake should have the following points.
1、 The friction coefficient shall be appropriate. Friction coefficient is the basic parameter of friction material, which determines the basic braking torque of brake pad. The national standard strictly requires the manufacturer to indicate the friction coefficient on the package. The friction coefficient must be appropriate. If the friction coefficient is too high, the wheel will be locked, the direction will be out of control and the disc will be burnt. If the friction coefficient is too low, the braking distance will be too long.
2、 The service life shall meet the standard. Service life is a product index that is widely concerned by everyone. Usually, the brake pad can guarantee the service life of 30000 km. Large grain graphite and brass used in brake pad materials can also reduce the wear of brake discs.
3、 Comfort. The direct embodiment of the comfort performance of small-scale mixer, including braking feeling, 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.
4、 The safety performance shall be reliable. The brake pad of the mixer truck will produce instantaneous high temperature during braking, especially during high-speed driving or emergency braking. At high temperature, the friction coefficient of the friction plate will decrease, which is called thermal degradation. The degree of thermal decay determines the safety of high temperature and emergency braking.
If there is a problem with the brake of the mixer truck, it must be replaced in time, and more attention should be paid to the selection. For more related matters, please visit our website http://www.sdzkjf.cn Consult and understand!
