前言研究的目的是为了提高闸瓦和轮箍的使用寿命和应用价值,提高制动安全及减少更换消耗部分,从而节约费用。一、闸瓦材料对制动机构造的影响闸瓦的制动作用愈强,制动力愈大。闸瓦作用于车轮上发生摩擦力(图1)的极限值是车轮与钢轨间的粘着力。当制动力超过粘着力,轮对将被抱闸。容许的制动减速与应用闸瓦材料及闸瓦构造类型有关。制动力为闸瓦压力和摩擦系数的乘积。车轮
Preface The purpose of the study is to save costs by improving the service life and application value of the brake shoe and wheel rim, improving brake safety and reducing the need to replace consumables. First, the impact of brake shoe material on the brake system brake brake shoe brake stronger, the greater the braking force. The limit value of the brake shoe friction on the wheel (Figure 1) is the adhesion between the wheel and the rail. When the braking force exceeds the adhesion, the wheel will be brake. Allowable brake deceleration and the application of brake shoe materials and brake types of construction. Braking force is the product of brake shoe pressure and friction coefficient. wheel
