A Detailed Analysis Of The Performance Of Disc Brake
Oct 16, 2017

In order to avoid the braking failure caused by prolonged braking, the accident will be forced to stop in the next long slope to make the brakes cool or to use water to force the cooling brake. The root cause of this problem is the common drum brake braking efficiency of the thermal stability is very poor, popular said drum brakes due to prolonged braking temperature rise and temperature rise after the braking effect obviously worse. The problem will be significantly improved after the disc brakes are installed because even though the temperature is significantly higher, the disc brakes can almost maintain the same braking force as the cold state. Disc brakes have many notable advantages over drum brakes.Disc Brake

In the long time continuous braking on one hand, the brake drum after heating expansion, the working radius increased, so that the brake drum can not maintain the full contact with the brake hoof; On the other hand, the friction coefficient between the brake shoe friction linings and the brake drum is reduced and the braking efficiency is reduced after the temperature increases. For disc brakes, the axial thermal expansion of the brake disc is minimal, while the radial thermal expansion is independent of the braking performance. At the same time, the effect of friction coefficient of braking friction linings and brake discs on braking performance is small, so the braking efficiency is reduced very little.Disc Brake Brake friction linings are high in unit pressure on the brake discs, so it is easy to squeeze water out and thus reduce the braking efficiency after soaking. Also because of centrifugal force and brake friction lining block on the brake disc wiping effect, after the water only need secondary braking that can return to normal. and drum brakes due to structural reasons, it will require even more than 10 brake side can be restored.Disc Brake
