The invention provides a valve core assembly of an air brake ABS electromagnetic valve of an automobile. The technical core of the assembly is as follows: a first valve core sub-assembly and a secondvalve core sub-assembly that are same in structure are arranged on a coil assembly in parallel, wherein the first valve core sub-assembly and the second valve core sub-assembly are reversely arrangedin the coil assembly. By changing the structures of the first valve element sub-assembly and the second valve element sub-assembly, the arrangement structure and position of a seal ring are changed, an air channel port of the electromagnetic valve is hermetically formed in a guide sleeve, a valve element is guided by the inner wall of the guide sleeve to move and is sealed to the air channel portof the guide sleeve, and sealing and movement are carried out for a same part. A radial seal is arranged at the upper end of the guide sleeve, so that the sealing reliability is improved greatly; Theguide sleeve and an upper connecting seal of an electromagnetic valve body are independently arranged to be of end face sealing structures, separately. When the valve element assembly of the electromagnetic valve is assembled, only one radial sealing fit is formed between the guide sleeve and the matching face of the electromagnetic valve body, so that the assembling difficulty and the risk of cutting the sealing ring are reduced.

    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。
