  • a very large overlapping or overlapping of the closure lines with the retaining strips can be achieved, with an overall length of the overlap being greater than 50 percent of an outer circumference of the lid.
  • an overlapping or overlapping between the closure elements of the cover and the closure elements corresponding thereto on the side of the filter housing can be achieved by less than 50 percent of an outer circumference of the cover. consequently is by means of the arcuate closure strips, a particularly good closure effect can be achieved when the insertion opening of the filter housing is closed by means of the cover.
  • the cover can also be detached from the filter housing again very easily and quickly, for example when the filter cartridge, which comprises the filter body and the cover arranged on the filter body, is to be replaced.
  • the closure strips protrude in the radial direction beyond the base body of the cover, the sum of the individual lengths of the respective closure strips allows a particularly large length of undercut gripping behind the retaining strips due to the closed position of the cover.
  • This is advantageous with regard to a secure mounting of the cover on the filter housing and a secure closure of the insertion opening of the filter housing in the closed position of the cover.
  • a particularly high level of stability of the individual closure strips can be achieved. This is because, distributed over the circumference of the lid, a comparatively large number of closure strips, each of which has a shorter length, or fewer and therefore longer closure strips can easily be accommodated.
  • the provision of a larger number of closure strips is also accompanied by a reduction in the angle of rotation through which the cover has to be rotated about the axis of rotation in order to bring the cover into the closed position.
  • the length of a transmission line, along which a closing force acts when the respective holding strip is gripped behind with the corresponding closing strip is greater the fewer closing strips the cover has overall. Therefore, by specifying a suitable number of closure strips, both a comparatively small twisting angle for bringing the cover into its closed position and very good retention of the cover brought into its closed position can be achieved.
  • the closure strips and the retaining strips are straight or extend along a straight line
  • the closure strip engages the retaining strip only at certain points when the lid is brought into the closed position.
  • the closure strip initially engages behind the retaining strip only in a very small area and not over the entire length of the retaining strip. Only with increasing rotational movement does the straight retaining strip increasingly grip behind along the likewise straight closure strip. Providing straight closure strips and retaining strips can therefore entail difficulties in bringing the lid into the closed position, in particular because the lid may become caught.
  • the collar part preferably protrudes in the radial direction beyond a housing pot of the filter housing, with the filter body of the filter cartridge being accommodated in the housing pot.
  • the filter cartridge according to the invention for a fluid filter of a motor vehicle comprises a filter body which can be introduced into the filter housing via an insertion opening of a filter housing of the fluid filter.
  • the insertion opening can be closed by means of a cover, which is arranged on the filter body of the filter cartridge.
  • the lid can be brought into a closed position by rotating it about a rotary axis.
  • the cover has a plurality of closure strips which, in a top view taken in the direction of the axis of rotation, are arcuate and protrude in the radial direction beyond a base body of the cover.
  • the closure strips each have a similar arc shape. This simplifies the assembly of the filter cartridge. This is because it is not necessary to pay attention to which sealing strip is introduced into which intermediate space which is formed in each case between holding strips of the filter housing which are adjacent in the circumferential direction. It has also been shown to be advantageous if the closure strips are arranged equidistantly from one another in the circumferential direction around the axis of rotation. This is particularly advantageous with regard to the simplicity of assembling the filter cartridge.
  • FIG. 5 shows a further step in the assembly of the filter cartridge, with the cover of the filter cartridge being in a starting position
  • FIG. 7 shows a detail of the fluid filter, with the cover of the filter cartridge being rotated into its closed position
  • FIG. 8 shows a detail of a sectional view of the fluid filter in the area of the collar part of the filter housing, with the cover being brought into its closed position according to FIG. 7;
  • FIG. 9 shows an enlarged detailed representation of a plan view of the fluid filter with the cover brought into the closed position
  • FIG. 10 shows a top view of the fluid filter in a variant of the fluid filter in an enlarged detailed representation
  • FIG. 11 shows a bottom view of a closure strip of the cover and a retaining strip of the filter housing corresponding to the closure strip, with the cover being in the initial position;
  • the force introduced from the filter housing 28 is here transmitted in the region of a transmission line 62 into the respective closure strip 20 .
  • An approximate course of the transmission line 62, which is formed on a front edge in the direction of rotation 24 of the horizontally extending closure strip 20, is indicated in FIG.
  • the overlap portion which depends on the length of the respective transmission line 62, is significantly greater than with a bayonet lock. This is because, due to the design, a cover with a bayonet catch can only have an overlap of less than 50 percent, with the overlap being expressed as the ratio of the sum of the individual lengths of the transmission lines to the outer circumference of the cover.
  • This support element 66 designed in the manner of a horizontal wall part, extends from the respective holding web 34 to a vertical wall 68 of the base body 18. The provision of the support elements 66 largely prevents the closure strips 20 extending away from the holding webs 34 from buckling.
  • Configuration of the lid 14 has a wall region 70, which starting from the annular flange area 58 of the cover 14 in the direction of the axis of rotation 22 .
  • the wall areas 70 embodied in the manner of reinforcing ribs ensure additional stabilization of the wall 68 , this stabilization helping to support the closure strips 20 .

Abstract

L'invention concerne un filtre à fluide (12) pour un véhicule automobile, comprenant un boîtier de filtre (28) et une cartouche filtrante (10). Une ouverture d'insertion (38) du boîtier de filtre (28), par l'intermédiaire de laquelle un corps de filtre (16) de la cartouche filtrante (10) est introduit dans le boîtier de filtre (28), est fermée au moyen d'un couvercle (14). Le couvercle (14) agencé sur le corps de filtre (16) de la cartouche filtrante (10) est amené en position fermée par rotation autour d'un axe de rotation (22). Le couvercle (14) présente une pluralité de barres de fermeture (20), qui sont arquées lorsqu'elles sont vues depuis le dessus dans la direction de l'axe de rotation (22). Les barres de fermeture (20) font saillie dans la direction radiale à partir d'un corps principal (18) du couvercle (14). Lorsque le couvercle (14) est en position fermée, les barres de fermeture (20) sont en prises derrière des barres de maintien (26) qui sont ménagées sur des côtés du boîtier de filtre (28) et qui sont arquées lorsqu'elles sont vues depuis le dessus dans la direction de l'axe de rotation (22). L'invention concerne également une cartouche filtrante (10) pour un filtre à fluide (12) de ce type.
