Abstract

The invention relates to a hydraulic double-state electromagnetic valve for an automobile braking system, and belongs to the field of automobile braking systems. The electromagnetic valve comprises a static iron core, a metal guide sleeve, a movable iron core, a reset spring, a valve body, a valve element, an upper O-shaped sealing ring, a valve element seat, a filter screen and a lower O-shaped sealing ring and has two states, one state is a normally-open state, the other state is a normally-closed state, and the normally-open state and the normally-closed state are switched at the same time. And after a coil is electrified, the switch state can be realized, the hydraulic oil runner of the braking system can be switched, and the coil is a key component of the hydraulic braking system. The electromagnetic valve has the advantages that the functions of two electromagnetic valves are achieved, system hydraulic pressure is accurately isolated, blocked and rapidly switched, a new structure can replace an original structure, function implementation is accurate and reliable, meanwhile, cost is reduced, the overall layout of the hydraulic system is improved, a normally-open valve and a normally-closed valve can be replaced, and the functions of opening the normally-closed valve and closing the normally-open valve can be simultaneously realized.

Description

technical field [0001] The invention belongs to the field of automobile braking systems, in particular to a hydraulic double-state solenoid valve for the automobile braking system. Background technique [0002] Solenoid valves are often used in automobile braking systems. In the past, solenoid valves were mainly normally open and normally closed to realize hydraulic on and off for flow channel switching. A solenoid valve is either a normally open valve or a normally closed valve. There will be a certain time difference when controlling the normally open and normally closed solenoid valves to work at the same time when the channel is switched. As the hydraulic brake system realizes more and more complex functions, the number of solenoid valves will also increase and the control will be more complicated, resulting in more failure modes and higher costs. Contents of the invention [0003] The invention provides a hydraulic two-state electromagnetic valve for an automobile br...
