Definitions

  • the invention relates to an arrangement for sealing a fan according to the preamble of claim 1 - known by the DE-A 198 03 502 the applicant.
  • holding and locking elements are arranged on the frame, which has a hollow cylindrical region, wherein these are preferably alternately distributed over the circumference.
  • the locking elements are designed as latching lugs, which can be latched with latching eyelets, which are molded onto the annular support.
  • the holding elements may be formed as hooks or annular groove segments, which extend only over parts of the entire circumference. This results in the possibility of inserting and clipping the holder with the brushes from behind, ie in the direction of the radiator in the frame.
  • the detents preferably have inwardly (to Mitielachse) directed wedge surfaces on which the eyelets of the holder slip during clipping, are deformed inwards, after passing the locking lugs again snap outwards and lock.
  • the annular holder is divided at least once in the circumferential direction, that is, in one or more radial planes.
  • the entire retaining ring is divided into three segments, in particular to 120 degrees Zentriwinkel, or into four segments, in particular to 90 degrees.
  • Fig. 1 shows a perspective view of a fan cover 1, which has an approximately rectangular plan, which is adapted to a not shown radiator or module carrier or the like of a motor vehicle, on which the fan cover 1 can be attached.
  • the fan cover 1 tapers to a circular frame 2, in which a non-illustrated fan, preferably an axial fan or a sheathed axial fan, so-called shell fan rotates, softer by the engine of a motor vehicle is driven.
  • the fan not shown promotes or sucks air through the radiator, not shown.
  • the fan In order to increase the efficiency of the fan and in particular to avoid a recirculation of air, the fan must be sealed against the frame, which will be discussed below.
  • Fig. 4 shows a part of the clip connection according to Fig. 3 namely the fan frame 2 before the clipping.
  • the locking lugs 5 are molded onto the inner wall of the fan frame 2 and protrude radially inwards (in the direction of the central axis).
  • annular groove segments 6 are molded onto the fan frame 2 alternately.
  • Fig. 6 shows a section along the line VI-VI in Fig. 3 , ie the clips or latching connection between latching lug 5 and 7 locking lug.
  • the latched in the detent 7 locking lug 5 thus causes a positive locking of the segment 4 in the axial direction and in the circumferential direction.
  • Fig. 7 shows a portion of the frame 2 without segment 4, wherein the frame 2 has a hollow cylindrical inner surface 2a, from which the locking lugs 5 and the Ringnutsegmente 6 protrude radially inwardly.
  • the locking lugs 5 point each oblique wedge surfaces 5ä, on the softer the eyelets 7 slide on insertion into the frame 2 and are temporarily deformed radially inward.
  • Fig. 8 shows a part of the segment 4 according to the connection in FIG Fig. 6 ,
  • the latching eye 7 shows the circumferentially extending rectangular slot 7 a, which is adapted in each case to the dimensions of the corresponding locking lug 5.
  • Fig. 9 shows a section along the line IX-IX in Fig. 3 , d: h. by a Ringnutsegment 6, which receives the lower part of the cross section of the segment 4 and fixed in both radial directions (inwards and outwards) and in an axial direction.
  • a plurality of Ringnutsegmente 6, preferably three for a segment 4 are provided.
  • the segment 4 - and also the other segments - fixed relative to the frame 2 and secured against falling out.
  • Fig. 10 shows the frame 2 with the cross section of the Ringnutsegmente 6, between which a latching lug 5 is arranged.
  • Figure 11 shows a part of the segment 4 with locking eye. 7
  • the flexible sealing elements or bristles of the brush seal have been omitted for the sake of simplicity.
  • bristles are attached to the segments, which thus serve as a support for the bristles, which cause the sealing of the fan relative to the frame.
