Description

一种制动缸防尘盖以及采用该防尘盖的可防水制动缸 技术领域
本发明属于车辆制动缸技术领域，特别涉及一种制动缸防尘盖以及采用该防尘盖的可防水制动缸。
背景技术
铁道车辆制动缸一般安装在车辆底部，车体会挡住雨水进入缸体，比如敞车，棚车等。但是有的车型，比如平车，罐车，水泥车等，车体没有完全挡住制动缸，雨水很容易淋到制动缸，进入制动缸。
如图1所示，现有铁路货车车辆制动缸只有防尘功能，没有防水功能，制动缸一旦在雨水天淋雨，雨水容易由图1中A、B、C三处流入到制动缸内部，特别是在制动缸缓解时，制动缸的活塞右侧会出现负压，雨水更容易被抽进缸体内，从而造成制动缸内部的污染及锈蚀，大大降低制动缸的使用寿命，影响行车安全。
发明内容
本发明的目的在于：针对上述存在的问题，提供一种能够有效防止雨水进入制动缸内，从而提高制动缸使用寿命，确保行车安全的制动缸防尘盖以及采用该防尘盖的可防水制动缸。
本发明的技术方案是这样实现的：一种制动缸防尘盖，所述制动缸防尘盖固定连接在制动缸的前盖上，其特征在于：在所述制动缸防尘盖的边缘处、沿其轴向设置有向外延伸的裙摆。
本发明所述的制动缸防尘盖，其所述裙摆整体呈喇叭口形。
本发明所述的制动缸防尘盖，其所述裙摆与制动缸防尘盖成型为一体结构。
一种采用了上述制动缸防尘盖的可防水制动缸，包括制动缸体和前盖，其 在所述前盖上设置有防水防尘盖组成，所述防水防尘盖组成包括固定连接在前盖上的制动缸防尘盖以及设置在制动缸防尘盖内的滤尘毡架和滤尘毡垫，所述滤尘毡架与制动缸防尘盖连接，所述滤尘毡垫固定在滤尘毡架上，在所述制动缸防尘盖的边缘处、沿其轴向设置有向外延伸的裙摆。
本发明所述的可防水制动缸，其在所述制动缸防尘盖的排气口处、沿其轴向设置有向外延伸的凸起部。
本发明所述的可防水制动缸，其在所述前盖内设置有用于安装前盖滤尘套的防水圈座，所述防水圈座套接在制动缸的活塞杆上，在所述防水圈座上、防水圈座与活塞杆之间设置有双唇防水圈，在所述防水圈座上、防水圈座与前盖之间设置有O形密封圈。
本发明所述的可防水制动缸，其在所述防水圈座的外端面设置有环槽，所述O形密封圈装配在环槽内。
本发明通过在现有制动缸易进水的位置设置密封结构，有效防止制动缸缓解时，雨水被制动缸内形成的负压吸入缸体内，从而起到防水作用，提高制动缸的使用寿命，确保行车安全。
附图说明

图2是本发明的结构示意图。
图3是图2中防水防尘盖组成的放大图。

图5是本发明中防水圈座的结构示意图。
图中标记：1为制动缸体，2为前盖，3为防水防尘盖组成，4为制动缸防尘盖，5为滤尘毡架，6为滤尘毡垫，7为裙摆，8为凸起部，9为环槽，10为 前盖滤尘套，11为防水圈座，12为活塞杆，13为双唇防水圈，14为O形密封圈B，15为缓解弹簧。
具体实施方式
下面结合附图，对本发明作详细的说明。
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
如图2和3所示，一种可防水制动缸，包括制动缸体1和前盖2，在所述前盖2上设置有防水防尘盖组成3，所述防水防尘盖组成3包括固定连接在前盖2上的制动缸防尘盖4以及设置在制动缸防尘盖4内的滤尘毡架5和滤尘毡垫6，所述滤尘毡架5与制动缸防尘盖4连接，所述滤尘毡垫6固定在滤尘毡架5上，在所述制动缸防尘盖4的边缘处、沿其轴向设置有向外延伸的裙摆7，所述裙摆7与制动缸防尘盖4成型为一体结构，所述裙摆7整体呈喇叭口形，在所述制动缸防尘盖4的排气口处、沿其轴向设置有向外延伸的凸起部8，进一步阻挡雨水进入防尘盖内。
如图3所示，当雨水顺着制动缸防尘盖流下来时，由于有制动缸防尘盖上裙摆的挡水作用，雨水直接沿着裙摆处下落，从而将气体通路与雨水流淌线路隔离，起到防水作用，当制动缸缓解时，滤尘器组成的滤尘毡垫上方形成负压，但由于雨水在裙摆阻挡作用下到不了制动缸防尘盖的C处，因此也就不会被吸入缸体内；即使是有极少部分雨水流到了C处，也会被C处的凸起部再次阻挡，从而确保雨水无法进入到制动缸防尘盖内。
如图4所示，在所述前盖2内设置有用于安装前盖滤尘套10的防水圈座11，所述防水圈座11套接在制动缸的活塞杆12上，在所述防水圈座11上、防水圈 座11与活塞杆12之间设置有双唇防水圈13，所述双唇防水圈材料为聚氨脂，硬度较高，减小与活塞杆的摩擦，能够防止雨水从A处进入缸体；在所述防水圈座11上、防水圈座11与前盖2之间设置有O形密封圈14，如图5所示，在所述防水圈座11的外端面设置有环槽9，所述O形密封圈14装配在环槽9内，通过缓解弹簧15的作用力，使O形密封圈14变形，起到密封作用，防止雨水从前盖与防尘圈安装座之间B处进入缸体。前盖滤尘套通过O形密封圈和双唇防水圈进行密封，避免与大气直接接触，其中储存的89M润滑脂挥发减少，氧化变质减缓，有利于活塞杆的润滑及防锈。
本发明针对图1中A、B、C三处漏水位置进行结构改进，通过密封结构的设置起到防水作用，有效防止雨水对制动缸内部的污染及锈蚀，提高了制动缸的使用寿命，确保了行车安全。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
