Abstract

The electromagnetically operated hydraulic valve has a ring-shaped end-stop (7) partly surrounded by a magnetic armature (3). The outer cylindrical surface of the ring-shaped end-stop which is first accurately positioned in the axial plane. During assembly, radial force is applied to the magnetic armature. This brings about partial plastic deformation and forces material into the recess (9), locking the relative position of the two components.

Description

The invention relates to a structural unit for a Electromagnetically actuated, normally open Hydraulic valve according to the preamble of claim 1.

Such units are u. a. for valves in hydraulic brake systems with slip control for Motor vehicles used in the basic position, d. H. in the de-energized state, are open and for slip control be closed, the closing pressure on one certain limit pressure is adjustable so that these valves at the same time to limit the maximum system pressure can be used (cf. DE 40 28 447 A1 and DE 42 04 417 A1).

To compensate for any manufacturing tolerances such valves set individually during pre-assembly will. Two are independent of each other Adjustments required. The first is the hub set around which the valve tappet is located Compression of the closing pressure determining between Valve tappet and magnet armature clamped spring relative to Magnetic armature can move axially, the second is the Stroke set by which the magnet armature is below Compress the valve opening Return spring axially relative to the valve seat fixed to the housing can move.  

The second setting is made so that between the housing-fixed magnetic core and the magnet armature one Setting disc of a predetermined thickness is inserted that then the valve tappet, magnetic core, compression spring and stop existing unit together with this unit enclosing sleeve-shaped valve dome in the closing direction is moved until the magnet armature and also the valve dome on its abutment comes into contact with the magnetic core. This "Double fit" is achieved by one on the magnet armature intended vulnerability is compressed. So that will the opening stop for the magnet armature is fixed, the after removing the shim and energizing the coil by the amount of the thickness of the shim to Counter stop on the magnetic core axially in the closing direction is movable. To stick between the magnetic core and Preventing magnetic anchors is usually done using a thin, non-ferromagnetic disc a residual air gap realized when dimensioning the shim is taken into account.

With the first setting, a Shim between magnet armature and magnet core inserted. The thickness of this shim is less than the stroke of the armature to be set in the second step. It determines the stroke by which the armature moves further Closing direction is movable when the valve lifter is already rests on the valve seat. Magnetic anchors, Valve tappet, compression spring and annular stop in one Assembly assembled, the stop non-positively in the central hole of the magnet armature used and under tension of the compression spring so far postponed that this is stronger than ultimately desired  is compressed. Then the unit is under Intermediate position of the shim in or on the fixed magnetic core and it becomes the Valve tappet together with the annular stop axially and moved relative to the armature until the valve lifter rests on the valve seat. In doing so, the compression spring again somewhat relaxed and the given stroke between Valve tappet and magnet armature set. With others Words, after removing the shim the Magnetic anchor by the set stroke further in Closing direction are moved as the valve lifter, causing at the same time the dimension is determined by which the compression spring can be compressed, or the amount of the Compression spring applied closing pressure. If the on the valve seat pressure acting on the valve tappet when the valve is closed greater than this set closing pressure opens that Valve despite energizing the solenoid, and the impermissible high overpressure can be reduced automatically.

From the setting process described last, that the outer dimension of the annular stop is very accurate on the inner diameter of the central bore in the magnet armature must be coordinated so that on the one hand during pre-assembly an axial displacement with reasonable effort is possible, but on the other hand in operation under changing static and dynamic loads the selected Adjustment of the ring-shaped stop safely ensured can be. It has been shown that the necessary Radial forces with a significant excess of the annular Attack against the central bore can be reached can that when inserting scrapes on the magnet armature are hardly avoidable, so that chips are formed  especially then impair the function of the valve can if they are not completely separated from the magnet armature and not be noticed and later during the Operate at some point.

On the other hand, there is always the risk that The unfavorable circumstances coincide Connection between ring-shaped stop and magnetic armature does not withstand the loads, so that the stop is moved and that eventually the valve is no longer is functional. For example, components meet, the individual dimensions of which are still within the Tolerance ranges lie, but only one within the network just tolerable press fit, the under unfavorable temperature conditions and / or at Limit loads no longer holds.

The invention is therefore based on the object To create unit of the type mentioned in the between ring-shaped stop and magnetic armature one Connection can be made using the above Does not have the disadvantages mentioned and those with reasonable Effort to establish the safe and permanent annular stop in its set position enables.

To achieve this object, the invention provides that the annular stop on its outside Cylinder surface has at least one recess into which after the axial adjustment of the stop by partial plastic deformation by means of an outside radially applied force material of the magnet armature  is impressible.

In this way, the previously conventional non-positive Connection supplemented by a form-fitting component will. It is obvious that all of these are mentioned Difficulties can be overcome. In particular, can you now work with much less oversize because the positive connection essentially only for the Pre-assembly must be designed and because the connection in Operation of the valve essentially through the positive Component is realized, with wide dimensional Design options arise and the power and positive parts can be varied within wide limits can. The setting itself is made easier and that subsequent plastic deformation can be applied to all occurring Load cases are adjusted. The additional Manufacturing outlay is extremely low, especially since a technology that has proven itself in valve construction can, in which often components due to caulking be determined.

Advantageous refinements of the inventive concept are described in subclaims 2 to 7. Further details are explained in more detail with reference to the embodiment shown in FIGS. 1 to 3. Show it:

In the fully assembled valve according to FIG. 1, the magnet armature 3 lies on top of the valve dome 21 , which forms the opening stop for the magnet armature 3 and limits the expansion path of the return spring 20 . In the illustrated open position of the valve tappet 1 , the through hole 12 a in the valve plate 12 is not closed and the flange 2 of the valve tappet 1 lies against the annular stop 7 , the compression spring 8 assuming its maximum possible expansion position. The valve lifter 1 is guided at the top in section 5 with a stepped narrower diameter of the armature 3 and at the bottom in component 15 . If the solenoid 22 is energized, valve tappet 1 and armature 3 are first moved down together in the closing direction, ie against the resistance of the return spring 20 , until the valve tappet 1 abuts the valve plate 12 and closes the through-hole 12 a. The axial movement of the valve lifter 1 is thus ended. However, the air gap between the armature 3 or friction disk 25 and the magnet core 19 is larger than the travel of the valve tappet, so that the magnet armature 3 can be moved further downward against the restoring force of the compression spring 8 until it rests on the magnet core 19 with the friction disk 25 . As already mentioned, the residual air gap is determined by the friction disk 25 . In the second movement section of the magnet armature, the annular stop 7 lifts off the flange 2 of the valve tappet 1 , so that in the end position there is a distance between the annular stop 7 and the flange 2 which corresponds to the set stroke by which the magnet armature 3 continues in the closing direction is movable than the valve lifter.

The annular stop 7 has a longitudinal slot 10 and is therefore shown hatched only in the left part of the illustration. In the right part of the illustration, material of the magnet armature 3 is pressed into the annular stop 7 , an impression point 9 a being formed on the outside of the magnet armature 3 due to the action of the tool. In the left part of the illustration, no material of the magnet armature 3 has yet been pressed into the recess 9 of the annular stop 7 and there is therefore no indentation point 9 a in the magnet armature 3 .

FIG. 2 is a fragmentary enlargement from FIG. 1, the details of the invention described last being more clearly apparent.

Fig. 3 shows the annular stop 7 in section and in view. Further explanations on FIGS. 2 and 3 are not required.
