Abstract

本发明提供了一种汽车气制动ABS电磁阀阀芯总成，其技术核心是：线圈总成上并列布置有两个结构相同的第一阀芯分总成、第二阀芯分总成，第一阀芯分总成、第二阀芯分总成在线圈总成中反向设置，本发明通过改变第一及第二阀芯分总成的结构，改变了密封圈的设置结构和位置，将与电磁阀气道口的密封设置在导套内，阀芯由导套内壁导向进行运动，并与导套气道口进行密封，密封与运动均相对同一个零件，同时在导套上端设置径向密封，极大提高了密封可靠性；将导套与电磁阀体的上连接密封分别单独设置成端面密封结构，在装配电磁阀阀芯总成时，与电磁阀体的配合面各仅有一个径向密封配合，降低了装配难度及切破密封圈的风险。

Description

一种汽车气制动ABS电磁阀阀芯总成
技术领域
本发明涉及汽车气制动ABS电磁阀领域，更确切地说涉及汽车气制动ABS电磁阀阀芯总成。
背景技术
ABS是在紧急制动或容易滑动的路面上制动时，防止车轮抱死、保证车辆的方向稳定性和操纵性为目的的电子制动控制系统。ABS通过电磁阀的开关对汽车制动压力进行调节来实现其功能，电磁阀中的阀芯总成是具体执行通断动作的机构，通常为双阀芯结构。
如图1所示，是目前气制动ABS普遍采用的电磁阀阀芯总成结构，包括一个线圈总成1，线圈总成上并列布置有两个结构相同的第一阀芯分总成A、第二阀芯分总成B，第一阀芯分总成A、第二阀芯分总成B在线圈总成1中反向设置，以第一阀芯分总成为主描述，包括由阀芯3、静铁芯2、导套6、阀芯复位弹簧7，静铁芯2与导套6通过滚压方式连接并密封，成为导套组件，第一阀芯分总成A的上下两个安装面各有两处径向密封O形圈（图1中标号5、9）以及一处阀芯3端部的阀口端面密封8，线圈总成1的两端还设有大端面密封圈（图1中标号4、10，第一阀芯分总成A与第二阀芯分总成B共用），阀芯3上的气道设置在外圆周上，对安装配合精度要求较高，且安装时容易切破密封圈，出现密封失效风险。
发明内容
本发明的目的在于提供一种汽车气制动ABS电磁阀阀芯总成，改变阀芯分总成的结构，改变密封圈的设置结构和位置，降低装配过程中产生的密封失效风险，同时可减少配合件加工工序及制造精度，降低电磁阀制造成本。
为达到上述目的，本发明采用的技术方案是：一种汽车气制动ABS电磁阀阀芯总成，包括一个线圈总成，线圈总成上并列布置有两个结构相同的第一阀芯分总成、第二阀芯分总成，第一阀芯分总成、第二阀芯分总成在线圈总成中反向设置，其特征在于：
第一阀芯分总成，包括导套、阀芯、橡胶阀门、静铁芯、复位弹簧、弹簧座，导套固定在线圈总成内，导套整体伸出有圆柱杆与电磁阀体的气道相应，圆柱杆上设有中心气道，圆柱杆上套装有第一径向密封圈，由第一径向密封圈与电磁阀体的气道形成径向静密封；导套上开有气孔，导套内腔由此与电磁阀体的控制气道相通，圆柱杆处的线圈总成处设有第一端面密封圈，形成端面密封；
阀芯装于导套内，通过橡胶阀门与中心气道的内气道口形成密封，静铁芯通过第二径向密封圈与导套内腔密封，并固定在线圈总成内，静铁芯的内腔压装有弹簧座，其上装有复位弹簧，推动阀芯与导套的中心气道进行密封，静铁芯底部的线圈总成处设有第二端面密封圈，形成端面密封；
第一阀芯分总成、第二阀芯分总成、线圈总成组合构成电磁阀阀芯总成。
对本发明的进一步限定：本发明中，第一径向密封圈、第二径向密封圈、第一端面密封圈及第二端面密封圈都是O形密封圈；这样是标准件，易于获得，利于安装。
对本发明的进一步限定：所述导套上安装有轭铁，用来增强电磁线圈总成的吸合力。
本发明的有益效果是：本发明改变阀芯分总成的结构，改变了密封圈的设置结构和位置，将与电磁阀气道口的密封设置在导套内，阀芯由导套内壁导向进行运动，并与导套气道口进行密封，密封与运动均相对同一个零件，同时在导套上端设置径向密封，极大提高了密封可靠性；本发明将导套与电磁阀体的上连接密封（第一阀芯分总成、第二阀芯分总成）分别单独设置成端面密封（第一端面密封圈、第二端面密封圈）结构，在装配电磁阀阀芯总成时，与电磁阀体的配合面各仅有一个径向密封配合，降低了装配难度及切破密封圈的风险。
