The invention provides a parking cylinder, a brake cylinder with a parking function, a brake clamp unit and a railway vehicle. The parking cylinder comprises a cylinder body; the locking mechanism can be movably installed in the cylinder body and has two working states of locking and unlocking, and the locking mechanism comprises a locking finger, a locking rod and a locking rod; the locking ratchet wheel is meshed with or separated from the locking finger, so that the locking mechanism is locked or unlocked, and parking braking or relieving of the parking cylinder is achieved; the locking rod is arranged between the locking finger and the locking ratchet wheel; the locking rod comprises a step section, a step extending towards the locking finger is arranged on the step section, the step is constructed to abut against the locking finger when the locking mechanism is locked, the step comprises a step edge, and the step edge jacks up the locking finger away from the locking ratchet wheel when the locking mechanism is unlocked. According to the technical scheme, the force application structure of the locking rod is optimized, the maximum relieving tension needed by relieving operation is reduced, the convenience of relieving operation is improved, and the overall performance of the parking cylinder is improved.
本申请提供一种停放缸、带停放功能的制动缸、制动夹钳单元以及轨道车辆。停放缸包括:缸体;以及锁止机构,其能够活动地安装在缸体中,并具有锁止和解锁两种工作状态,锁止机构包括:锁止指;锁止棘轮,锁止棘轮与锁止指啮合或分离,使得锁止机构锁止或解锁,从而实现停放缸的停放制动或缓解;以及锁止杆,锁止杆设置在锁止指与锁止棘轮之间;锁止杆包括台阶段,台阶段上设置有朝向锁止指延伸的台阶,台阶构造成在锁止机构锁止时抵靠锁止指,台阶包括台阶棱边,其在锁止机构解锁时将锁止指远离锁止棘轮顶起。根据本申请的技术方案,优化了锁止杆的施力结构,减小了缓解操作所需的最大缓解拉力,提高了缓解操作的便捷性,提高了停放缸的整体性能。
