一、目的大型货车上的空重车重量差很大,制动作用时,若施行适宜重车用的制动力制动,则空车时,制动力过大,车轮在轨道上滑行。反之若施行适宜空车制动力制动时,侧重车时的制动力显得不足。空重车制动装置能按空重车重量需要调整制动力。图1为空重车制动装置作用示意图。 First, the purpose of large empty truck on a large weight difference between vehicles, the braking effect, if the implementation of appropriate heavy vehicles with the braking force braking, the empty car, the braking force is too large, the wheels glide on the track. On the contrary if the implementation of appropriate brake for empty car brake, when the emphasis on car braking force appears inadequate. Empty and heavy truck braking device can empty the weight of the car needs to adjust the braking force. Figure 1 is a schematic diagram of the role of empty heavy truck brake.
