Definitions

  • Housing block with a mounting hole for a component, such as a solenoid valve or the like.
  • the invention is based on a housing block with a receiving bore for a circular cross-section of a component, such as a solenoid valve or the like, according to the preamble of the main claim.
  • the arrangement according to the invention consisting of the housing block and the component with the characterizing features of the main claim has the advantage that, on the one hand, by dimensioning the circumferential groove and the fastening element, both a play-free and a play-fitting interlocking connection between the housing block and the component can be achieved. On the other hand, this connection can be produced with very little effort, since pliers (as in the case of spring washers) or other tools are unnecessary for inserting the fastening element into the gap, and the expansion of the fastening ring can be carried out in a simple manner with a depressing punch which moves into the gap.
  • FIG. 1 shows a cut-open housing block with a component arranged in a receiving bore and with an annular fastening element for the component inserted into the bore
  • FIG. 2 shows a section along line II-II in FIG. 1 with that in a gap between the receiving bore
  • 3 shows a representation corresponding to FIG. 1 with an expanded fastening element engaging in a circumferential groove of the receiving bore
  • FIG. 4 shows a section along the line IV-IV in FIG. 3 with the fastening element deformed compared to FIG. Description of the embodiment
  • the exemplary embodiment shown in the drawing shows a section of a housing block 10 with a receiving bore 11, in which a section 12 of a component 13, for example a solenoid valve, a cover or a closure of the bore, is received.
  • the stepped receiving bore 11 has an opening-side, cylindrical section 14 which is delimited by a bore step 15. After the bore step 15, the receiving bore 11 continues with a section 16 of smaller diameter.
  • the component 13 with its section 12 of circular-cylindrical cross section fits in the smaller-diameter section 16 of the receiving bore 11. This gives the component 13 a radial guidance.
  • the component 13 is provided all around with a flange 20.
  • the component 13 is supported on the bore step 15 with this graduated diameter transition.
  • the component 13 has a section 21 of smaller diameter starting from the flange 20.
  • a gap 22 of the same width, which is circular in plan, is thus formed.
  • the flange 20 against the opening side of the receiving bore 11, has an end face 25 which extends radially, ie at right angles to the longitudinal axis of the receiving bore 11 and the component 13.
  • the opening-side section 14 of the receiving bore 11 is provided with a circumferential groove 26. This is laterally through parallel to the longitudinal axis, parallel groove flanks 27 and 28 limited, the groove flank 28 remote from the opening being aligned with the end face 25 of the component flange 20.
  • the base 29 of the circumferential groove 26 extends parallel to the longitudinal axis of the receiving bore 11.
  • An annular fastening element 32 is inserted into the annular gap 22 (FIG. 1). As FIG. 2 shows, it has an essentially circular ring shape.
  • the fastening element 32 is punched out of sheet metal, the maximum radial width of its cross section being within the width of the gap 22.
  • the fastening element 32 is provided with two diametrically opposite sections 33 and 34 which bulge axially out of its plane. In the exemplary embodiment, these form the two legs of an isosceles triangle (see FIG. 1). Deviating from this, the bulge can also have a circular arc shape. Sections 35 and 36 with a crescent shape extend between the two curved sections 33 and 34 of the fastening element 32, as clearly shown in FIG.
  • the fastening element 32 can be pushed onto the section 21 of the component 13 and can be introduced into the annular gap 22 without aids. When the fastening element 32 resting on the flange 20 of the component 13, this is aligned on the end face with the groove flanks 27 and 28 of the circumferential groove 26.
  • the curved sections 33 and 34 of the fastening element 32 are directed towards the opening side of the receiving bore 11.
  • a depressing die 38 indicated by dash-dotted lines in FIG. 1, with the gap 22 adapted shape moves down on the curved sections 33 and 34 and levels them out by plastic deformation. As a result, the fastening element 32 experiences a permanent radial expansion. As FIGS.
  • the receiving bore 11 of the housing block 10, the component 13 and the fastening element 32 are dimensioned such that there is axial and radial clearance between the component 13 and the housing block 10.
  • deviations from this are possible in a simple manner:
  • An axially free play can be set by means of an axially narrower flange 20 or a fastening element 32 with a smaller thickness than the circumferential groove 26.
  • Radial play is adjustable if the flange 20 has a smaller diameter than the opening-side section 14 of the receiving bore 11 and the fastening element 32 ends in front of the base 29 of the circumferential groove 26.

Abstract

L'invention vise à réaliser l'assemblage permanent, par liaison de forme, d'un élément (13) et d'un bloc carter (10), dont la réalisation n'implique pas une grande complexité technique. Un bourrelet (20) de l'élément (13) s'engage dans un alésage (11) échelonné du bloc carter (10). L'alésage (11) comporte une rainure périphérique (26), côté ouverture. Un élément de fixation (32) annulaire est introduit dans l'espace (22) situé entre l'élément (13) et l'alésage (11). Une pression exercée sur des sections voûtées faisant saillie à partir du plan de l'élément de fixation (32) permet audit élément de fixation (32) de rester élargi en permanence pour s'engager dans la rainure périphérique (26).
