一、粘着系数的概念车辆在加速或制动时,轮轨间会产生粘着力。如果这个力很小,那么车轮就容易空转或滑行。表示车轮踏紧钢轨面的程度的值叫粘着系数,粘着系数乘以轴重所得的值就是粘着力。近代的车辆,与过去使用蒸汽机车牵引真空制动机的时代不同,其加速力或制动力很容易加大,但是不管加大到多大的值,如果没有粘着力,那么,不仅施加的力起不到它的作用,而且会使车轮滑动、踏面 First, the concept of adhesion coefficient When the vehicle accelerates or brakes, the wheel rail will have adhesion. If this force is small, then the wheel is free to slip or glide. The value of the degree of the wheel tread on the rail surface is called the adhesion coefficient. The value obtained by multiplying the adhesion coefficient by the shaft weight is the adhesion force. Modern vehicles, unlike those that used steam locomotive traction vacuum brakes in the past, can easily increase their acceleration or braking force. However, no matter how large the value is, if there is no adhesion, then not only the applied force Not its role, but also make the wheel slide, tread
