The invention discloses a self-adaptive deceleration strip, and belongs to the technical field of traffic facilities. When a vehicle passes by and contacts with a deceleration strip mechanism in a device provided by the invention, an extrusion force is applied to an arched memory alloy plate; the memory alloy plate has a downward moving trend; the extrusion force is transmitted to a rubber bag body arranged in a lower portion so that water filled in an inner cavity of the bag flows to a flow limiting valve from a liquid outlet, and due to the action of the flow limiting valve, if a flow speedexceeds a standard set by the flow limiting valve, the flow limiting valve blocks circulation, namely the volume of the rubber bag body is not changed, and the whole deceleration strip mechanism is still in a convex state and feeds back a large vibration feeling to a vehicle; and when a vehicle speed is low, the extrusion force on the rubber bag body is small, a water medium can normally circulate only when the flow speed of the water medium is smaller than the standard of the flow limiting valve, the water medium in the rubber bag body flows into a storage barrel through a one-way valve A, the size of the rubber bag body is reduced, and the deceleration strip mechanism is flattened so that a vehicle can smoothly pass through the deceleration strip mechanism. The structure is simple, andmechanical damage caused by rolling pressure is avoided.
本发明公开了一种自适应减速带，属于交通设施技术领域。当车辆行经接触到本发明装置中的减速带机构时，对拱形记忆合金板施加挤压力，使记忆合金板具有向下移动的趋势，将挤压力传至下方的橡胶囊体使得囊内腔中填充的水从出液口流向限流阀，由于限流阀的作用，若流速超过限流阀设定的标准，限流阀将会阻断流通，即橡胶囊体体积不变，使得整个减速带机构仍然呈凸起状态，反馈给车辆较大的振动感；当车速较低，对橡胶囊体的挤压力较小，使水介质的流速小于限流阀标准才能够正常流通，橡胶囊体内的水介质经单向阀A流入到储存桶中，橡胶囊体体积缩小，减速带机构被压平，从而使车辆可平坦驶过，本发明结构简单且不易受碾压力产生机械损伤。
