The invention provides a rail transit foundation braking device, and belongs to the technical field of brakes. The basic braking device solves the problem that an existing basic braking device is insufficient in braking force when air consumption is reduced. The rail transit foundation brake device comprises a connecting frame, a clamp arm and a brake cylinder, the brake cylinder comprises a shell and a push cylinder, the push cylinder is in threaded connection with a threaded sleeve, a mandrel is arranged in the threaded sleeve in a penetrating mode, a clutch is connected between the mandrel and the threaded sleeve, and a cam which can act on the threaded sleeve and is provided with a lever part is hinged to the interior of the shell. The cam is provided with two limiting faces oppositely arranged in the circumferential direction of the cam, the mandrel is provided with a protruding stirring part located between the two limiting faces, the two limiting faces can act on the stirring part to drive the mandrel to rotate, and when the stirring part abuts against one limiting face, a gap is formed between the stirring part and the other limiting face. According to the rail transit foundation braking device, sufficient braking force can be guaranteed while the gas consumption is reduced, and the rail transit foundation braking device is compact in structure and light in weight.

    本发明提供了一种轨道交通基础制动装置,属于制动器技术领域。它解决了现有基础制动装置在降低耗气量时导致制动力不足等问题。本轨道交通基础制动装置,包括连接架、夹钳臂和制动缸,制动缸包括壳体和推筒,推筒螺纹连接有螺套,螺套中穿设有芯轴,芯轴与螺套之间连接有离合器,壳体内铰接有能够作用在螺套上的具有杠杆部的凸轮,凸轮上具有在凸轮的周向上相对设置的两个限位面,芯轴上设置有凸出的且位于两个限位面之间的拨动部,两个限位面能够分别作用于拨动部带动芯轴转动,且当拨动部与其中一个限位面贴靠时拨动部与另一限位面之间具有间隔。本轨道交通基础制动装置能够在减少耗气量的同时保证足够的制动力,结构紧凑且轻量化。
