Description

可控气弹簧装置
一种可控气弹簧装置用于汽车驾驶员座椅高低的调节,属于调节机构技术领域。
本实用新型作出以前,在已有技术中,其主要包括缸体、活塞杆,导向套、端轴、活塞、阀芯、前后盖板。活塞杆上分别安装导向套、端轴、活塞、阀芯等部件,并安装在壳体内。导向套与活塞杆间直接接触,由于经常磨损、摩擦系数高、易损坏、直接影响其使用寿命,活塞与缸体间无密封装置,其密封性能差,易泄漏氮气,造成阀芯失控,不能起到调节作用。本实用新型的目的在于克服上述不足之处,从而提供一种活塞杆与导向套间不直接磨损,能延长使用寿命,密封性能好,能真正起到调节作用的可控气弹簧装置。
本实用新型的主要解决方案是这样实现的;其主要在活塞杆1上分别安装导向套3,密封圈座4、活塞杆1顶端安装端轴6,并安装在活塞7内,活塞7内安装阀芯9,阀芯9伸入活塞杆1内组成活塞杆组件,活塞杆组件安装在缸体5内。导向套3与活塞杆1之间安装复合套20;活塞7与缸体5间安装双唇口密封圈16。
附图说明;
图1是本实用新型主视图;
下面本实用新型将结合附图中的实施例作进一步描述:
本实用新型活塞杆1上安装导向套3,密封圈座4,活塞杆1顶端安装端轴6后安装在活塞7内,活塞7内安装阀芯9,阀芯9上安装O形座8,阀芯9伸入活塞杆1内,活塞杆1组件安装在缸体5内,盖上盖板2。导向套3与活塞杆1间安装复合套20、防止磨损,密封圈座4与活塞杆1之间安装唇口密封圈1 3,密封圈座4与导向套3之间安装O形圈12。端轴6内安装唇口密封圈15,O形圈14,活塞7与缸体5间安装双唇口密封圈16,阀芯9后端安装O形圈17,缸体5后端安装后封盖11,后封盖11上安装衬套10,采用O形圈18、19密封。
本实用新型与已有技术相比具有以下优点;1、由于活塞杆与导向套之间安装复合套减少之摩擦,摩擦系数低,不易损坏,可延长其使用寿命;2、活塞与缸体之间安装了双唇口密封圈;端轴内安装了唇口密封圈,因此活塞杆装置密封性能好,不易泄漏氮气,使用中阀芯不易失控,真正能起到调节座椅高低的作用。
