The invention discloses a steering locking air cylinder, and relates to the technical field of car manufacturing. The cylinder comprises a cylinder base and a shell body mounted at one end of the cylinder base in a sleeving manner, a push disc is in sliding connection into the shell body, a push pipe connected with the push disc is movably mounted in the cylinder base in a penetrating manner, theother end of the cylinder base is provided with a limiting step, a return spring sleeving the push pipe is arranged between the limiting step and the push disc, a push rod is arranged in the push pipethrough a positioning block, a gap is reserved between the positioning block and the push pipe, an interval exists between one end of the push rod and the push disc, the other end of the push rod extends out of the cylinder base to be provided with a joint, a ventilation pipe joint is arranged on the outer end of the shell body, a ventilation plug is arranged at the position, close to the limiting step, of the cylinder base, and compared with the prior art, the air cylinder has the advantages that compression air of an air pressure brake system standard equipped for a large and medium bus isadopted for driving to achieve the steering locking function, the whole bus does not need to be provided with a hydraulic system, cost is low, chassis space is saved, the air cylinder is clean and environment-friendly, the hidden danger of environment polluting caused by hydraulic oil leakage can be removed, the structure is simple and reliable, and mounting and adjusting are convenient.

    本发明公开了一种转向锁止气缸,涉及汽车制造技术领域,包括有缸座和套装于缸座一端的外壳体,外壳体内滑动连接有推盘,缸座内活动穿装有与推盘连接的推管,缸座的另一端设有限位台阶,在限位台阶与推盘之间装有套在推管上的回位弹簧;推管内通过定位块装有推杆,定位块与推管之间留有间隙,推杆一端与推盘之间设有间距,另一端伸出缸座装有接头;在外壳体的外端装有通气管接头,缸座上靠近限位台阶处装有通气塞。与现有技术相比,本发明采用大中型客车标配的气压制动系统的压缩空气来驱动实现转向锁止功能,整车无需再布置一套液压系统,成本低廉,节省底盘空间,清洁环保,消除了液压油泄漏污染环境的隐患。该结构简单可靠,安装调整方便。
