The parking brake cylinder comprises a cylinder body, an energy storage mechanism and a locking mechanism, and the energy storage mechanism comprises a parking cylinder cover, a parking piston and a first elastic piece; the locking mechanism comprises a first connecting piece, a second connecting piece, a first transmission piece, a second elastic piece and a thrust ball. A first parking position and a second parking position are arranged between the first transmission piece and the first connecting piece; when the thrust ball is located at the first parking position, the first connecting piece and the second connecting piece can slide relatively; when the thrust ball is located at the second parking position, the positions of the first connecting piece and the second connecting piece are relatively locked; parking braking or relieving operation can be completed through cooperation of the cylinder body, the energy storage mechanism and the locking mechanism, the structure is simple, and the size and weight of the parking brake cylinder are reduced.

    本申请涉及一种停放制动缸,包括缸体、储能机构及锁止机构,其中:储能机构包括:停放缸盖、停放活塞与第一弹性件;锁止机构包括:第一连接件、第二连接件、第一传动件、第二弹性件与推力球;第一传动件与第一连接件之间设有第一停放位与第二停放位;推力球位于第一停放位时,第一连接件与第二连接件可以相对滑动;推力球位于第二停放位时,第一连接件与第二连接件的位置相对锁止;本申请通过缸体、储能机构及锁止机构的配合可以完成停放制动或缓解的作业,结构简单,减小了停放制动缸的体积及重量。
