In terms of vehicle configuration, the safety of braking can be ensured and controlled mainly in the face of emergencies, especially for special vehicles such as concrete mixer. 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. The basic brake should have the following points.
1. Appropriate friction coefficient. 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. Service life. 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 comfort performance of small concrete mixer is directly reflected, including braking feeling, noise, dust, smoke, odor, etc. Under the basic premise of safety, comfort has become an important index of friction plate.
4. Safety. 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.
Generally speaking, the brake pad of the mixer truck should have four basic requirements. As mentioned above, you can understand it after reading it.
