Abstract
The utility model relates to an ABS solenoid valve component, in particular to an ABS normally open solenoid valve structure. The ABS normally open solenoid valve structure comprises fixed iron, movable iron and a plunger tube covered outside the movable iron, wherein, a spring is arranged inside the fixed iron, a valve seat is arranged at the bottom part of the solenoid valve, and a one-way valve hole is arranged at the bottom part of the valve seat. The utility model is characterized in that the connecting point between the fixed iron and the plunger tube adopts a fixation way by welding, and a pad is covered on the outer layer at the middle section of the fixed iron. The ABS normally open solenoid valve structure has the advantages of reasonable structure, simplified assembly process, lower manufacturing cost, high qualified rate for the product assembly and smaller volume, etc.
Description
Technical field
The utility model relates to a kind of ABS electromagnetic valve component, especially relates to a kind of ABS normally open solenoid valve structure.
Background technology
As everyone knows, at present popular in the world anti-block braking system of car (ABS) all adopts the switch of electromagnetic valve to realize automatically regulating to brake-pipe pressure, prevent phenomenon such as sideslip that wheel lockup produces, whipping and drive the generation of skidding, with the control that realizes car brakeing stability or drive skidproof function.Each wheel is by the logical switch electromagnetic valve control of two two twice of abs pressure regulating control, and normally open valve is opened under the normal brake application situation, and normally closed valve cuts out.
Traditional ABS normally open solenoid valve structure by plunger tube, decide structures such as iron, spring 17, moving iron 18, valve body, gland 11, O shape circle 12, downside spring 13, valve seat, spool, unidirectional valve opening and form, sees Figure of description 2 for details.Wherein, plunger tube 14 is by with valve body 10 with decide iron 15 crimps assembling, is difficult to guarantee the squareness of plunger tube and decide gap between iron and moving iron, the response time that influences electromagnetic valve with assemble qualification rate; And unidirectional valve opening 16 is an inclined hole, and it is processed at valve body, because the degree of depth is big, is difficult for processing.In addition, on oad, the conventional confguration volume is bigger, and manufacturing cost is higher.
Summary of the invention
The utility model mainly be at the existing in prior technology complex structure, assembly technology is loaded down with trivial details, manufacturing cost is high, product assembling qualification rate is low, volume is bigger etc. technical matters, provide a kind of rational in infrastructure, assembly technology is simplified, manufacturing cost is lower, product assembling qualification rate height, the less ABS normally open solenoid valve structure of volume.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of ABS normally open solenoid valve structure, comprise and decide iron, moving iron and be set in the moving exterior plunger tube of iron, decide iron inside and be provided with spring, solenoid valve base is provided with valve seat, the valve seat bottom is provided with unidirectional valve opening, it is characterized in that described junction of deciding iron and plunger tube is fixing for welding, describedly decide iron stage casing skin and be arranged with pad.The utility model extends the iron of deciding in the conventional confguration downwards, has reduced by four assemblies, is respectively downside spring, gland, O shape circle and valve body, wherein valve body with decide iron and synthesize one; Plunger tube by and decide between the iron to adopt laser welding to fix, guaranteed the squareness of plunger tube and decided gap between iron and moving iron; Increase pad, both guaranteed the magnetic circuit relation between coil and the electromagnetic valve, simplified the processing and assembling of deciding iron again.
As preferably, described plunger tube length is 9mm-14mm.The plunger tube dimensions length shortens, and has optimized the drawing process of plunger tube.
As preferably, described unidirectional valve opening is vertical with the solenoid valve base plane.Unidirectional valve opening is vertical with the solenoid valve base plane, and unidirectional valve opening is processed as straight hole, is convenient to processing.
As preferably, described pad is a circular ring, and its radius is 5mm-10mm.Gasket construction had both guaranteed the magnetic circuit relation between coil and the electromagnetic valve, had simplified the processing and assembling of valve body again.
As preferably, be arranged with the ring filter screen outside the described valve body lower end.It is rational in infrastructure, designs ingenious.
As preferably, described valve seat bottom is provided with the end filter screen.Simple in structure, manufacturing process is simplified relatively.
Therefore, the utlity model has characteristics such as rational in infrastructure, that assembly technology is simplified, manufacturing cost is lower, product assembles the qualification rate height, volume is less.
