现在广泛应用的减速顶是一种自动控制车辆溜放速度的调速工具,它能够自动地根据对车辆溜放速度的判别来决定是否对车辆起制动作用,却不能够由人们根据调车作业的实际需要来决定是否对车辆起制动作用。自从可控减速顶由哈尔滨减速顶调速系统研究中心研制成功以后,我国增添了一种可由人们根据需要控制使用的减速顶,即人们需要它起制动作用时,就给电控阀断电,它就和普通减速顶一样正常工作,人们如果不需要它起制动作用,就给电控阀通电,它就因滑动油缸部分被
Now widely used deceleration top is a kind of speed control tool automatically control the vehicle speed, it automatically based on the speed of vehicles to determine the speed of the vehicle to play a braking role, but can not be based on shunting The actual needs of the job to decide whether to play a braking role on the vehicle. Since the controllable deceleration top was successfully developed by Harbin Deceleration Head Speed System Research Center, China added a deceleration top which can be controlled by people according to needs, that is, when people need it to brake, it will power off the electric control valve , It works just like a normal decelerating top. If people do not need it to brake, it will energize the electric control valve. Because of the sliding cylinder part being
