The invention relates to the technical field of automobile braking, in particular to an automobile air brake ABS electromagnetic valve element assembly which comprises a coil assembly, a guide sleeve,a valve element, stop iron and a spring assembly. The first end part of the guide sleeve is fixed in the coil assembly; the stop iron is fixed in the first end part of the guide sleeve; the spring assembly is arranged in the stop iron; the valve element is arranged in the guide sleeve, the first end part of the valve core is matched with the air channel opening in the stop iron, and the second end part of the valve core is matched with the air channel opening in the guide sleeve; the first end of the valve element is connected with the spring assembly. According to the automobile air brake ABS electromagnetic valve element assembly, the second end of the valve element is matched with the air channel opening of the guide sleeve, that is, the sealing position of the electromagnetic valve air channel opening is arranged in the guide sleeve assembly, the valve element is guided by the inner wall of the guide sleeve to move and is sealed with the guide sleeve air channel opening, and sealing and moving are both relative to the same part, and sealing reliability is greatly improved.
本发明涉及汽车制动技术领域,特别涉及一种汽车气制动ABS电磁阀阀芯总成,包括:线圈总成、导套、阀芯、挡铁及弹簧组件。导套的第一端部固定在线圈总成内;挡铁固定在导套的第一端部内;弹簧组件设置在挡铁内;阀芯设置在导套内,阀芯的第一端部与挡铁上的气道口配合,阀芯的第二端部与导套的气道口配合;阀芯的第一端部与弹簧组件相接。本发明提供的汽车气制动ABS电磁阀阀芯总成,阀芯的第二端部与导套的气道口配合,即将电磁阀气道口的密封位置设置在导套组件内,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,极大提高了密封可靠性。
