【技术实现步骤摘要】
本技术所涉及一种汽车弹簧制动气室的改进专利技术,尤其是涉及一种活塞式内呼吸型弹簧制动气室。
技术介绍
目前机动车所用的制动气室是一种外呼吸型弹簧气室,大活塞,活塞轴,堵头都有O型密封圈密封,大活塞在向上或向下运动时,腔内要吸入或呼出气体,所以就在呼吸腔设置排气孔,排气孔用皮管与前气室壳体连接;但是外呼吸结构的制动气室皮管容易老化脱落,导致污水和泥沙很容易进入呼吸腔,就会影响呼吸腔主要部件的使用寿命。
技术实现思路
本技术的目的在于针对外呼吸式弹簧制动气室所存在的技术问题,提供的是一种结构简单,设计合理,不会导致污水,泥沙进入制动气室而增加后气腔内部件的使用寿命及性能稳定的一种活塞式内呼吸型弹簧制动气室。为了解决上述技术问题,本技术是采用了如下方式完成的。本技术的内呼吸型弹簧制动气室,是由前气室壳体及与其相连的后气室壳体和连接前后气室壳体的中壳体所组成,前气室壳体与皮膜组成气腔,在气腔内设有推盘组件,推盘组件上设有回位弹簧座,回位弹簧座上设有回位弹簧。后气室壳体内设有大活塞组件,大活塞组件内设有设有活塞轴,还设有驻车弹簧和吊杆组件,吊杆组件的一端设于活塞轴内,其另一端通过 ...
