The invention discloses a speed reducer for a freight rail train. The speed reducer comprises a bottom supporting base plate, a main hollow shell is installed on the upper surface of the bottom supporting base plate, and a main hollow structure, an auxiliary hollow structure and an air reserved space which are parallel to one another are sequentially arranged in the main hollow shell from one sideto the other side of the main hollow shell; and a main limiting space is formed in the bottom of the main hollow structure. According to the speed reducer, spiral springs are used for generating thedamping effect on wheels, and meanwhile, a flowing channel of high-pressure air is opened through the gravity effect of the train on the device, so that a certain wind resistance effect can be generated on the side face of a carriage, the damping effect combining two kinds of force is achieved, and the damping effect is higher; and meanwhile the device conducts wind resistance through the gravityof the train, and after the train completely passes through, the damping effect of the high-pressure air can be automatically closed along with the time when the pressure disappears, so that the gravity of the train is effectively utilized, and the application is more convenient.

    本发明公开了一种货运轨道列车用降速器,包括底部支撑基板,所述底部支撑基板的上表面安装一主空心壳体,所述主空心壳体的内部由其一侧到另一侧的内部依次设有平行的主中空结构、副中空结构和空气预留空间,所述主中空结构的底部设有主限位空间。本发明利用螺旋弹簧产生对车轮的阻尼效果,同时,再利用火车对该装置的重力效果打开高压空气的流动通道,能够对车厢的侧面产生一定的风阻效果,从而实现两种力度的结合阻尼效果,阻尼效果更强,同时,该装置利用火车重力进行风阻,在火车完全经过后,能够随之压力消失的时间,自动关闭高压空气的阻尼效果,从而有效利用火车的重力,更加方便应用。
