The invention relates to a motor train unit braking system, and particularly relates to a zipper type brake cylinder corrugated protective sleeve. The zipper type brake cylinder corrugated protectivesleeve solves the problem that in the existing corrugated protective sleeve maintaining process, a clamp needs to be detached from a bogie to replace the corrugated protective sleeve, and the replacement difficulty is large. The zipper type brake cylinder corrugated protective sleeve comprises a dustproof cover body, a waterproof zipper and a suture line; the waterproof zipper is sewn and fixed onthe dustproof cover body through the suture line; adhesive is evenly smeared on the whole contact face between the waterproof zipper and the two ends of the dustproof cover body, the suture line in the extension direction of the suture line and the surface of the exposed suture line on the outer surface of the dustproof cover body, and the closed tail end of the waterproof zipper is arranged at the large end of the dustproof cover body.; and after the adhesive is cured, stainless steel hose clamps are installed at the two ends of the dustproof cover body. According to the zipper type brake cylinder corrugated protective sleeve, the sealing performance of the corrugated protective sleeve is guaranteed while replacement is convenient; the fatigue performance requirement and the reliabilityof the zipper type corrugated protective sleeve are guaranteed; the low-temperature resistance and the high-temperature resistance of the zipper type corrugated protective sleeve are guaranteed; and the sewing quality between the corrugated protective sleeve rubber and the zipper is guaranteed.

    一种拉链式制动缸波纹保护套,涉及动车组制动系统,解决现有波纹保护套维修过程中,需要将夹钳从转向架上拆除,才能对波纹保护套进行更换,存在更换难度大的问题,包括防尘罩体、防水拉链和缝合线;防水拉链通过缝合线缝合固定在防尘罩体上;在防水拉链与防尘罩体两端内整个接触面、沿缝合线延展方向的缝合线处以及防尘罩体外表面外露缝合线表面均匀涂抹粘合剂,防水拉链的闭尾端设置在防尘罩体大端处。在粘合剂固化后,在防尘罩体的两端安装不锈钢喉箍。本发明在方便更换同时保证波纹保护套的密封性能;保证拉链式波纹保护套的疲劳性能要求及可靠性;保证拉链式波纹保护套的耐低温及耐高温性能以及保证波纹保护套橡胶与拉链间的缝合质量。
