传统的减速顶只有判断速度的功能。因此,当车辆的速度超过临界值时,减速顶就对其进行制动;当车辆逆驼峰方向作业,如反向发车、重复解编时减速顶同样对车辆产生的制动作用,除了增大车辆和减速顶的磨损外,还要增大机车牵引力和增加能耗。当反牵速度超过15km/h时还容易使轻车脱线。因此 The traditional deceleration top only to determine the speed function. Therefore, when the speed of the vehicle exceeds the critical value, the decelerating roof brakes it. When the vehicle is operating in the direction opposite to the hump, such as starting in the reverse direction, the deceleration effect of the decelerating roof on the same decelerating roof also increases the braking effect, Vehicles and deceleration roof wear, but also increase locomotive traction and increase energy consumption. When the anti-pull over 15km / h when the car is also easy off-line. therefore
