Description
Technical field
The utility model is related to control valve technical fields, are especially a kind of anti-blocking brake system normally open solenoid valve.
Background technology
Anti-blocking brake system abbreviation ABS, applied in motorcycle brake system, effect is exactly in motorcycle brake
When, the size of braking device brake force is automatically controlled, makes wheel not by locking, the state slided always in side rolling, so as to prevent
Motorcycle whipping in braking process, remains that the adhesive force on wheel and ground is maximum, so as to ensure minimum braking distance,
It can ensure the insensitivity of vehicle simultaneously, improve drive safety and comfort.
At present, normally open solenoid valve is mainly used for logic control during braking in motorcycle ABS：It is normally opened in conventional brake
Solenoid valve dead electricity, brake fluid flow directly out normally open solenoid valve, play logical oil, while in normally open solenoid valve internal one-way valve channel
The check valve assembly of setting is closed with the beginning of braking, is opened after braking.During motorcycle abs braking, it is being pressurized
Stage is opened without control signal, normally open solenoid valve on normally open solenoid valve, and flowing through the brake fluid come by master cylinder cannot enter singly
To valve passage, but corresponding brake piping is entered, and enter brake cylinder by air-brake coupling hose by normally open solenoid valve valve port,
Brake pressure is made constantly to increase.Packing stage, only applying electric signal to normally open solenoid valve makes its closing, has just cut off braking in this way
Contacting between wheel cylinder and master cylinder remains unchanged its internal pressure.In decompression phase, to it is normally opened, normally closed solenoid valve is same
When apply electric signal, normally open solenoid valve electromagnetism is closed, and normally closed solenoid valve is opened, and each brake cylinder is connected with way valve passageway,
Brake fluid in wheel cylinder will pass through pressure reducing valve valve port and enter spring piston type accumulator, realize the reduction of brake pressure.At this point, such as
Fruit abs braking is over, and the brake fluid in accumulator can flow back to braking under the action of scavenge oil pump with lifting for brake pedal
Master cylinder.Therefore the check valve assembly of normally open solenoid valve frequently realizes open-close function during abs braking.It is and existing
The check valve assembly of technology normally open solenoid valve includes being arranged on the way valve passageway being connected in valve body and with valve body oil inlet, single
A steel ball is equipped with to the lower end of valve passage, the steel ball is when valve body oil inlet is into brake fluid, with the impact force of brake fluid
Simultaneously leakproof one-way valve channel is held out against, preventing brake fluid from entering in way valve passageway leaks brake fluid.Due to steel ball and list
There is certain free gap between valve passage, when steel ball holds out against simultaneously leakproof one-way valve channel with brake fluid, it may occur that system
Hydrodynamic is leaked in way valve passageway in advance, and steel ball sealing way valve passageway needs the regular hour, influences normally opened electricity in this way
The performance of magnet valve, it is impossible to meet the requirement of motorcycle ABS high-precision control for brake.
Utility model content
The technical problems to be solved in the utility model is the defects of overcoming the more than prior art, to provide a kind of performance
It is good, and the anti-blocking brake system normally open solenoid valve of ABS high-precision control for brake requirements can be met.
