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.
