The invention provides an urban rail transit vehicle braking buffer device, and mainly relates to the technical field of urban rail transit. An urban rail transit vehicle braking buffer device comprises a wheel, a transmission shaft is fixedly installed on one side of the wheel, grooves are formed in the two sides of the wheel respectively, the periphery of the transmission shaft is sleeved with a positioning block coaxial with the transmission shaft, and an annular groove is formed in the side, close to the wheel, in a through hole; a first friction ring is installed in the annular groove in a sliding fit mode, a second friction ring is arranged between the wheel and the positioning block, the first friction ring can move into the groove corresponding to the first friction ring, a friction assembly capable of making contact with the first friction ring is arranged on the side, away from the wheel, in the annular groove, and a displacement assembly is arranged on the side, away from the wheel, of the positioning block. The brake pad has the beneficial effects that through the arrangement of a double-layer friction structure, buffering of vehicle braking is achieved, abrasion of the brake pad is reduced, the service life of the brake pad is prolonged, and the maintenance cost is reduced.

    本发明提供一种城市轨道交通车辆制动缓冲装置,主要涉及城市轨道交通技术领域。一种城市轨道交通车辆制动缓冲装置,包括车轮,所述车轮的一侧固定安装有传动轴,车轮的两侧分别开设有凹槽,所述传动轴的外周套装有与其同轴设置的定位块,通孔内靠近车轮的一侧开设有环形槽,环形槽内滑动配合安装有第一摩擦环,所述车轮与定位块之间设有第二摩擦环,且第一摩擦环能够移入与其对应的凹槽内,所述环形槽内远离车轮的一侧设有能够与第一摩擦环接触的摩擦组件,所述定位块远离车轮的一侧设有位移组件。本发明的有益效果在于:本装置通过设置双层摩擦结构,实现了对车辆制动的缓冲,降低了刹车片的磨损,延长了刹车片的使用寿命,减少了维修成本。
