The electromagnetic valve for the automobile braking system has the advantages that the structure is novel, an electromagnetic coil component does not need to be fixed independently, and the cost and assembly process difficulty are obviously lowered while high-pressure sealing performance and magnetism-conductive performance of an electromagnetic circuit are guaranteed. Besides, when a single electromagnetic valve fails to work, the damaged electromagnetic valve can be replaced independently, the failure of an entire HCU assembly is avoided, and the yield of the entire HCU assembly is obviously improved.
Description
Technical field
The invention belongs to automobile industry, refer in particular to the hydraulic control unit assembly that is applied to the automobile brake electric stabilizing system.
Background technique
Solenoid valve is the critical component of automobile brake electric stabilizing system.Dispose a plurality of solenoid valves in the hydraulic control unit assembly of an automobile brake electric stabilizing system.By the control of the solenoid valve to relevant, realize the adjusting to different wheel wheel cylinder brake fluid pressure, guarantee braking safety and the travelling comfort of automobile.In the HCU assembly of present automobile brake electric stabilizing system, solenoid valve directly with HCU assembly main valve seat interference riveted joint, be used for resisting the high pressure of inside, non-dismountable.Its shortcoming is: electromagnetic coil assembly needs fixing separately, and if one of them solenoid valve inefficacy in assembling or using process, can't change separately, cause whole HCU assembly all to lose efficacy.
Summary of the invention
The invention provides a kind of brake system of car solenoid valve, with the solution electromagnetic coil assembly, need to fix separately, and if one of them solenoid valve inefficacy in assembling or using process, the problems that cause whole HCU assembly all to lose efficacy can't be changed separately.
technological scheme of the present invention is: gland is fixedly connected with main valve seat by four uniform screws, between gland and main valve seat, gasket seal is arranged, gland, magnetic conduction casing, coil brace, shoulder, main valve seat is axial compression successively, axial clearance S1 is arranged between electromagnetic valve body top and gland, axial clearance S2 is arranged at magnetic conduction upper surface of washer and coil brace bottom, magnetic conduction casing bottom and the gapped S3 of main valve seat upper surface, the central hole of magnetic conduction casing has inside flange, magnetic conduction casing top inner ring coordinates with outer ring, electromagnetic valve body top radial clearance, magnetic conduction casing bottom inner ring coordinates with magnetic conduction packing ring outer ring radial clearance, magnetic conduction packing ring inner ring and shoulder outer ring Spielpassung, large annular groove and little annular groove are arranged on electromagnetic valve body, large O type circle is arranged in large annular groove, little O type circle is arranged in little annular groove, the valve opening of electromagnetic valve body and main valve seat is by in large annular groove, the radial seal of little O type circle, the shoulder external diameter is greater than the valve opening aperture of main valve seat, shoulder lower plane and main valve seat upper surface compress location, electromagnetic coil is positioned at coil brace, spool is positioned at electromagnetic valve body, antifreeze plate, be arranged on the spool upper end, spring is by antifreeze plate and spool crimping, spring and electromagnetic valve body apical grafting, inlet opening is arranged respectively on main valve seat, liquid outlet opening leads to the valve opening of valve seat, sealed base is positioned at the liquid outlet opening top, liquid outlet opening has the liquid outlet opening filter screen at the valve opening inner opening place of valve seat, sealed base and the crimping of liquid outlet opening filter screen, inlet opening has the inlet opening filter screen at the valve opening inner opening place of valve seat.
[0005]The invention has the advantages that: novel structure, electromagnetic coil assembly do not need fixing separately, in the magnetic property that guarantees high pressure sealing performance and electromagnetic circuit, significantly reduce costs and the assembly technology difficulty.And can change separately after single solenoid valve loses efficacy, and can not cause the inefficacy of whole HCU assembly, significantly improve the rate of good product of HCU assembly.Structure of the present invention is unique, and reliable performance, can be widely used in automobile industry.

Embodiment
Magnetic conduction casing, magnetic conduction packing ring, spool, electromagnetic valve body material are electromagnetic pure iron, for reducing costs, magnetic conduction casing is stamping part, and the effect of interior hole flanging has two: can increase magnetic conduction casing coordinates area with electromagnetic valve body on the one hand, reduce magnetic resistance, be beneficial to magnetic conduction; Axial force is concentrated acted on the inner ring of coil brace, prevent the squeeze and destroy to electromagnetic coil.Main valve seat, gland, coil brace are non-magnet material, as aluminum alloy, more than wall thickness 1.5mm.There is insulation coating on the coil brace surface, prevents the electromagnetic coil electric leakage.
During the electromagnetic coil energising, magnetic conduction casing, magnetic conduction packing ring, spool, electromagnetic valve body form magnetic conductive loop.The electromagnetism air gap is formed at spool and electromagnetic valve body inner chamber top, and spool promotes under electromagnetic force, and the normally close valve valve port is opened.
The effect of magnetic conduction packing ring is to strengthen the space of electromagnetic coil in the situation that do not increase the external diameter of shoulder, reduces technology difficulty and the processing cost of electromagnetic valve body.
When electromagnetic valve work, electromagnetic valve body inside is subject to very large hydraulic coupling, and maximum can reach 20MPa, owing to there being gap S1, and S2, S3, pressure are delivered to shoulder, coil brace, magnetic conduction casing, gland successively.Screw diameter more than 5mm, can bear the pulling force that produces due to internal high pressure.Coil brace is Al-alloy parts, can bear large extruding force and not deform.By the shoulder transmission, gap S1 is left at the electromagnetic valve body top due to pressure, so the electromagnetic valve body top do not stress, and can not cause the distortion of electromagnetic valve body thin-walled inner chamber, guarantees the reliability of electromagnetic valve work.Electromagnetic valve body and main valve seat valve opening adopt large O type circle and the radial seal of little O type circle, only need while changing solenoid valve screw is screwed out, gland, magnetic conduction casing, electromagnetic coil and coil brace, magnetic conduction packing ring are taken out, will successively original magnetic conduction packing ring, electromagnetic coil and coil brace, magnetic conduction casing, gland be reinstalled to origin-location after the normally close valve unit replacement.
