Abstract
The utility model relates to an ABS electromagnetic valve subassembly, in particular to a normally closed ABS electromagnetic valve. The normally closed ABS electromagnetic valve comprises a fixed iron piece, a moveable iron piece and a valve body sleeved at the outside of the moveable iron piece; a spring is arranged inside the moveable iron piece; a valve seat is arranged at the bottom of the valve body. The normally closed ABS electromagnetic valve is characterized in that a clearance is left between the fixed iron piece and the moveable iron piece, and the fixed iron piece and the moveable iron piece are connected through welding; a gasket is arranged on the outer sleeve of the middle section of the valve body. The ABS electromagnetic valve subassembly is reasonable in structure and low in manufacturing cost and is simplified in installation process with high qualified rate.
Description
Technical field
The utility model relates to a kind of ABS electromagnetic valve component, especially relates to a kind of ABS normally closed solenoid valve structure.
Background technique
As everyone knows, at present popular in the world anti-locking system for car (ABS) all adopts the switch of solenoid valve to realize adjusting to retardation pressure, to reach the function that control riding stability or driving are skidded, prevent phenomenon such as sideslip that wheel lock up produces, whipping and drive the generation of skidding, guarantee insensitivity, shorten stopping distance.Each wheel is by the logical switch electromagnetic valve control of two two twice of abs pressure regulator, and normally open valve is opened under the normal brake application situation, and normally close valve cuts out.
Traditional ABS normally closed solenoid valve structure, by plunger tube, decide structures such as iron, spring, moving iron, valve body, guide sleeve 15, gland 16, valve seat, antifreeze plate, spool and form, see Figure of description 2 for details, wherein, plunger tube 9 is by assembling with valve body 10 extrusion-deformations, be difficult to guarantee that the perpendicularity of plunger tube reaches the gap of deciding between iron 11 and the moving iron 12, influence the response time and the assembling up-to-standard rate of solenoid valve.And antifreeze plate 13 difficulty of processing in this normally closed solenoid valve are very big, and long 5.5 millimeters of this antifreeze plate is wide 2.7 millimeters, 0.1 millimeter of thickness, and the center has will go out 9 apertures, therefore very difficult to its manufacturing.In addition, moving iron and spool 14 to press-fit operation also very loaded down with trivial details.So this apparatus structure complexity, manufacture 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, manufacture cost is high, product assembling up-to-standard rate is low etc. technical problem, provide a kind of rational in infrastructure, assembly technology is simplified, manufacture cost is lower, the high ABS normally closed solenoid valve structure of product assembling up-to-standard rate.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of ABS normally closed solenoid valve structure, comprise the valve body of deciding iron, moving iron and being set in moving iron outside, moving iron inside is provided with spring, the valve body bottom is provided with valve seat, it is characterized in that describedly deciding to leave the gap between iron and the moving iron, the joint of deciding iron and valve body is fixing for welding, and described valve body stage casing skin is arranged with pad.The utility model has been cancelled the plunger tube structure in the conventional art, by with valve body with decide the iron laser bonding and fix, be easy to guarantee to decide the gap between iron and moving iron; Cancel structures such as the guide sleeve in the conventional art, gland and spool, reduced the operation that press-fits of moving iron and spool in traditional assembly technology thus; Valve body stage casing skin is arranged with gasket construction, has both guaranteed the magnetic circuit relation between coil and the solenoid valve, has simplified the processing and assembling of valve body again; Cancel the very big antifreeze plate of difficulty of processing in the conventional art, simplified assembling process of products greatly.
As preferably, described length of deciding iron and valve body joint is 0.5mm-3mm.Valve body and decide between the iron to adopt laser bonding to fix is easy to guarantee to decide the gap between iron and moving iron.
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 solenoid 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 rational in infrastructure, characteristics such as assembly technology is simplified, manufacture cost is lower, product assembling up-to-standard rate height.
Description of drawings
Accompanying drawing 1 is a kind of structure sectional view of the present utility model.
Accompanying drawing 2 is a kind of structure sectional views of traditional ABS normally closed solenoid valve.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
A kind of ABS normally closed solenoid valve structure, comprise the valve body 3 of deciding iron 1, moving iron 2 and being set in moving iron outside, moving iron inside is provided with spring 4, the valve body bottom is provided with valve seat 5, decide to leave the gap between iron and the moving iron, the joint of deciding iron and valve body is fixing for welding, and valve body stage casing skin is arranged with pad 6.The length of deciding iron and valve body joint is 2mm.Pad is a circular ring, and its radius is 8mm.The valve body lower end outside is arranged with ring filter screen 7.The valve seat bottom is provided with end filter screen 8.
When installing and using, by with valve body with decide the iron laser bonding and fix, be easy to guarantee to decide the gap between iron and moving iron; Valve body stage casing skin is arranged with gasket construction, has both guaranteed the magnetic circuit relation between coil and the solenoid valve, has simplified the processing and assembling of valve body again.
