Definitions

  • the invention is based on a positive connection of a solenoid valve with a housing block according to the type of the main claim.
  • connection according to the invention of a solenoid valve with a housing block with the characterizing features of the main claim has the advantage that a reduced cost backlash-free, highly resilient position fixation is achieved.
  • the cross-sectional shape of the gap has a favorable effect on the force required for the deformation of the packing.
  • the material consumption for the packing is reduced. Since this only fills part of the gap, there is no possibility of non-destructive dismantling. However, this is acceptable if the quality level is sufficiently high.
  • the cross-sectional shape of the gap is advantageous in that the filler body takes on a wedge shape in cross-section and therefore holds the solenoid valve down in the receiving bore of the housing block without play.
  • the measure disclosed in claim 3 allows the preferably use of a housing block made of a cast aluminum alloy, without overloading it in terms of strength during the shaping process of the packing.
  • the embodiment specified in claim 4 is conducive to the axial and radial fixation of the solenoid valve in the housing block, because forces occurring during the shaping process of the filler body are advantageously absorbed by the solenoid valve and diverted into the housing block.
  • the exemplary embodiment of a positive connection shown in the drawing shows a solenoid valve 1, which is intended for use in a hydraulic vehicle brake system, not shown.
  • the solenoid valve 1 has a cylindrical jacket sleeve 2 which overlaps a solenoid 3.
  • a valve base 4 is accommodated in the casing sleeve 2 and fastened by caulking the sleeve edge.
  • a centering shoulder 5 of the solenoid valve 1 is formed on the valve base 4.
  • the solenoid valve 1 is received with a valve body section 8 in a stepped receiving bore 9 of a housing block 10 shown only in sections.
  • the housing block 10 consists of a cast aluminum alloy.
  • the cylindrical receiving bore 9 has a section 11 which is delimited by a bore step 12.
  • the valve body section 8 is axially supported with its valve base 4 at this bore step 12.
  • the cylindrical section 11 of the receiving bore 9 has a diameter which is slightly larger than the maximum diameter of the valve body section 8.
  • the receiving bore 9 is provided with an undercut 16 adjacent to an opening-side section 11.1.
  • the undercut 16 is in the shape of a truncated cone and merges into a transition radius which ends on the inner circumference of the receiving bore 9.
  • the undercut 16 closes a cone angle d. to the longitudinal axis 17 of the receiving bore 9 and the solenoid valve 1 of approximately 30 °.
  • the valve body section 8 of the solenoid valve 1 has a cylindrical zone 20 in the area of the cylindrical section 11.1 of the receiving bore 9. In the area of the undercut 16, this zone merges into a conically enlarging zone 21. With the longitudinal axis 17, this includes a cone angle A3 of approximately 40 °. After the conical zone 21, the valve body section 8 is continued with a cylindrical zone 22, leaving little radial play to section 11.2 of the receiving bore 9.
  • a parallel limited gap 25 is formed between the opening-side section 11.1 and the cylindrical zone 20, which in the area of the undercut 16 decreases in cross-section with increasing depth of the bore.
  • an annular filler 26 is pressed from a cold deformable wrought aluminum alloy.
  • the filler body 26 In the initial state, the filler body 26 has the shape of a hollow cylindrical ring, indicated by dash-dotted lines, of relatively short axial extent. In the pressed state, the filler 26 completely fills the gap 25 in the region between the undercut 16 of the receiving bore 9 and the conical zone 21 of the valve body section 8.

Abstract

La présente invention se propose de réaliser une liaison par forme d'une électrovanne (1) avec un bloc-carter (10) qui puisse supporter de fortes charges, qui économise des matériaux et qui soit facilement réalisable. Le bloc-carter (10) comporte un perçage de positionnement (9), lequel se termine, en fonction de l'augmentation de la profondeur de perçage, par une contre-dépouille (16). Une partie d'électrovanne (8) logée dans le perçage de positionnement (9) forme une fente périphérique (25) dans le bloc-carter (10). La fente (25) a dans la zone de la contre-dépouille (16) une section qui diminue en fonction de l'augmentation de la profondeur de perçage. La fente (25) est remplie dans la zone de la contre-dépouille (16) par un corps de remplissage plastiquement déformable (26). Le corps de remplissage (26) établit la liaison par forme entre l'électrovanne (1) et le bloc-carter (10). L'électrovanne (1) est fixée axialement et radialement.
