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.
  • the fan is driven by the internal combustion engine of a motor vehicle and is therefore “motor-fixed” stored.
  • the fan runs in a frame of a fan cover, which is attached to a radiator, which in turn is supported against the body of the vehicle, the fan frame is therefore “vehicle-fixed”.
  • a so-called brush seal As a result of the relative movements of the engine relative to the vehicle body, a larger gap between the fan blade tips and the frame must be maintained, which is sealed in the known arrangement by a so-called brush seal.
  • the latter consists of an annular holder, which has approximately radially inwardly standing flexible sealing elements or bristles and is attached to the fan cowl.
  • the annular holder which carries the flexible sealing elements or bristles of a brush seal, can be clipped into the frame.
  • the elements for a clip connection are usually simple, they can be mounted both on the frame and on the holder and are thus easy to manufacture, especially if it is plastic injection molded parts.
  • 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.
  • the retaining elements on the frame are formed so that they additionally form a radial securing, which is caused by the hook-shaped or ringnutförmige training (Ringnutsegmente) is achieved.
  • Ringnutförmige training Ringnutsegmente
  • the locking elements in the form of locking lugs and detents on the segments and a backup in the circumferential direction, ie, achieved against rotation.
  • Fig. 1 shows a perspective view of a fan cover 1, which has an approximately rectangular plan, which is adapted to a cooler or module carrier or the like of a motor vehicle, not shown, 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 recirculation of air, the fan must be sealed against the frame, which will be discussed below.
  • Fig. 2 shows the fan cover 1 gerharidianß Fig. 1, wherein in the frame 2, a so-called brush ring 3 is used to seal the fan. According to the invention, the insertion of the brush ring 3 in the frame 2 by clipping, ie there are no additional fastening means necessary.
  • Fig. 3 shows a part of the brush ring 3, namely a segment 4, which extends approximately over a circumferential region of 90 degrees and attached to the inner wall of the fan frame 2, that is clipped.
  • the entire brush ring 3 is thus divided into three segments, which are substantially the same design and distributed over the circumference are attached to the frame 2.
  • the bristles of the brush seal are omitted - the segments form the support for the bristles.
  • the type of attachment will become apparent from the following figures, on the one hand locking elements in the form of locking lugs 5 and on the other hand holding elements in the form of Ringnutsegmenten 6 are provided on the fan frame 2.
  • Frame and segments are designed as plastic injection molded parts.
  • Fig. 4 shows a part of the clip connection according to FIG. 3, namely the fan frame 2 before the Verclipsung.
  • 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. 5 shows the segment 4 of the brush ring 3, wherein two detent eyes 7 are provided which have a Kirckenden in the circumferential direction slot 7a.
  • 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 Rastiata the latched in the detent 7 locking lug 5 thus causes a positive securing of the segment 4 in the axial direction and in the circumferential direction.
  • Fig. 7 shows a part 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 compound in Fig. 6.
  • the detent 7 shows the circumferentially extending rectangular slot 7a, which is in each case adapted 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.
  • 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.
