The invention relates to the technical field of rail transit, in particular to a tread braking device. The device comprises a power base and a push rod slidably connected to the power base in a penetrating mode. An upper sliding groove and a lower sliding groove are vertically and symmetrically formed in the power base. An arc-shaped sliding groove communicating with upper sliding groove and lowersliding groove is formed in the side wall of the right end in the power base. An oil feeding mechanism and an oil collecting mechanism are arranged on the upper side of the left portion and the lowerside of the left portion of the power base respectively, and the oil feeding mechanism comprises an oil storage cavity formed in the upper side of the left portion of the power base and communicatingwith the upper sliding groove and an oil blocking ring arranged between the oil storage cavity and the upper sliding groove. Abrasion between the push rod and the power base can be reduced; meanwhile, lubricating oil can be recycled, and loss of the lubricating oil is reduced.
本发明涉及轨道交通技术领域,具体涉及一种踏面制动装置,包括动力座和贯穿滑动连接于动力座的推杆,动力座内部上下对称开设有上滑槽和下滑槽,且动力座内部右端侧壁开设有连通上滑槽与下滑槽的弧形滑槽,动力座左部上侧与左部下侧分别设置有给油机构和集油机构,给油机构包括开设在动力座左部上侧并与上滑槽相通的储油腔、设置在储油腔与上滑槽之间的阻油环;本发明有利于减少推杆和动力座之间磨损,同时可实现润滑油的循环回收利用,减少润滑油的损耗。
