The invention relates to a pulse control two-position two-way electromagnetic valve for an automobile braking system, and belongs to a component in an automobile hydraulic control braking system. One end of the sliding block is in sliding fit with the guide groove, the other end of the sliding block is fixedly connected with the valve element, the valve seat is in laser welding with the magnetism isolating pipe, the valve element is in sliding fit with the inner wall of the magnetism isolating pipe, the sliding pin component is installed between the special-shaped sliding groove and the flat-bottom through groove, and the electromagnetic valve coil is installed outside the fixed iron and the magnetism isolating pipe. The electromagnetic valve has the advantages that the structure is novel, compared with a traditional two-position two-way normally-closed electromagnetic valve, only one sliding block with a special-shaped flat-bottom sliding groove and one sliding pin component are additionally arranged, electromagnetic valve pulse control and electromagnetic valve opening and closing state circulation switching are achieved, an electromagnetic valve coil does not need to be powered on for a long time, and the electromagnetic valve is convenient to use. Assembling pre-pressure exists between the sliding pin component and the bottom face of the sliding groove, friction force, vehicle vibration and other interferences cannot cause the sliding pin component to deviate from a preset track, and it is guaranteed that the electromagnetic valve works reliably.
本发明涉及一种汽车制动系统用脉冲控制二位二通电磁阀,属于汽车液压控制制动系统中的部件。定铁与隔磁管激光焊接固定,滑块一端与导向槽滑动配合,滑块另一端与阀芯固定连接,阀座与隔磁管激光焊接,阀芯与隔磁管内壁滑动配合,滑销部件安装在异形滑槽与平底通槽之间,电磁阀线圈安装在定铁和隔磁管外部。优点在于结构新颖,相比于传统的两位两通常闭电磁阀只增加一个带有异形的平底滑槽的滑块和一个滑销部件,实现对电磁阀脉冲控制,电磁阀开启和关闭两种状态循环切换,电磁阀线圈无需长时间通电,滑销部件与滑槽底面有装配预压力,产生摩擦力,车辆振动等干扰不会导致滑销部件偏移预定的轨迹,保证电磁阀工作可靠。
