The invention discloses a rail transit near-rail speed reduction device, and relates to the technical field of rail transit equipment, the rail transit near-rail speed reduction device comprises two wheels, an axle coaxially arranged between the two wheels, a speed reduction assembly and a control switching assembly, the speed reduction assembly comprises a speed reduction disc and two groups of brake shoe mechanisms, the two brake shoe mechanisms are symmetrically arranged on the two sides of the speed reduction disc and can apply friction resistance to the speed reduction disc. The input end of the control switching assembly is connected with a brake air pump of a train, the output end of the control switching assembly is connected with different brake shoe mechanisms, and the control switching assembly is used for controlling and switching the connection states of the two brake shoe mechanisms and the brake air pump, so that the two brake shoe mechanisms alternately apply frictional resistance to the speed reduction disc. The two brake shoe mechanisms alternately work by controlling the switching assembly, heat generated in the braking process is dispersed, and the problem that the local temperature is too high due to long-time continuous work of a single brake shoe piece is solved.

    本发明公开了一种轨道交通近轨减速装置,涉及轨道交通设备技术领域,包括两个车轮、同轴设置于两个车轮之间的车轴、减速组件和控制切换组件,所述减速组件包括减速盘和两组闸瓦机构,其中减速盘同轴固定安装在车轴上,两组闸瓦机构对称设置于减速盘的两侧并能够对减速盘施加摩擦阻力;所述控制切换组件输入端连接列车的刹车气泵,所述控制切换组件的输出端分别连接不同的闸瓦机构,用于控制切换两个闸瓦机构与刹车气泵的连接状态,使两个闸瓦机构交替对减速盘施加摩擦阻力。本发明通过控制切换组件实现这两个闸瓦机构的交替工作,分散了制动过程中产生的热量,避免了单一闸瓦片长时间连续工作导致的局部温度过高问题。
