The invention belongs to the field of railway vehicle damping component manufacturing, and discloses a method for preventing a wear-resisting plate on a longitudinal backstop from falling off, the wear-resisting plate is installed on a lower metal plate at the lower end of the longitudinal backstop through bolts, and a groove is formed in the bottom end face of the wear-resisting plate, so that dirty water and chippings generated by the wear-resisting plate can be discharged through the groove; impurities such as chippings are prevented from being accumulated at the bolts, and the bolts are prevented from rusting and loosening and the wear-resisting plate falls off.
本发明属于轨道车辆减震部件制造领域,公开了避免纵向止挡上耐磨板脱落的方法,耐磨板通过螺栓安装于纵向止挡下端的下金属板上,通过在耐磨板底端面上开设沟槽,使得脏水及耐磨板产生的碎屑能通过沟槽排出,避免碎屑等杂质在螺栓处堆积,避免螺栓锈蚀松动及耐磨板脱落。
