我国车辆制动技术的发展（三）孙新海卜华娜吕换小孙福祥３粘着系数３．１粘着力制动力是闸瓦压力乘以闸瓦与车轮间的摩擦系数，粘着力是轴载荷乘以车轮与钢轨间的粘着系数。设计车辆时，要遵守制动力小于粘着力的原则，不然，车轮就要在钢轨上产生滑行，造成踏面擦伤。为... The development of China’s vehicle braking technology (c) Sun Xinhai Bu Hua Na Lv Hui Xiao Sun Fuxiang 3 adhesion coefficient 3.1 Adhesion Braking force is the brake shoe pressure multiplied by the friction coefficient between the brake shoe and the wheel, the adhesion is the axle load multiplied by the wheel Cohesion coefficient with rail. When designing a vehicle, observe the principle that the braking force is less than the sticking force. Otherwise, the wheel will have to glide on the rail, causing the tread to bruise. for...
