空气制动装置靠摩擦力实现制动 ,若有水及冰雪介于摩擦面之间 ,则因摩擦系数降低而影响制动效果。有冰雪时制动力降低更为明显。近年来 ,既有线上拖车的比率高 ,特别是拖车中分担制动比率高的盘形制动器性能差是一隐患 ,为此 ,对刹车面的材质以及耐雪制动器的效果 ,模拟降雪时
Air brake device to achieve braking by friction, if water and ice between the friction surface, the friction coefficient is reduced and thus affect the braking effect. When snow and ice reduce the braking force is more obvious. In recent years, there is a high ratio of existing on-line trailers. In particular, the poor performance of the disc brakes, which share the high braking ratio in the trailer, is a hidden danger. Therefore, on the material of the braking surface and the effect of the snow-
