Definitions

  • the invention relates to a fan, in particular for conveying cooling air, in particular for an internal combustion engine, comprising a hub on which a plurality of fan blades is arranged and wherein the hub has a rib structure.
  • Vibrations of the internal combustion engine are thus transmitted via the coupling to the fan.
  • the fan thus experiences strong vibration excitations in all directions, both as axial displacements but also in the form of tilting.
  • an impeller for a semi-axially acting fan which has a hub on which a plurality of fan blades is arranged.
  • the hub of the fan is provided with a hub ramp, which is arranged rising on the outside of the hub.
  • the hub itself is provided with cavities which are separated by radially extending web parts against each other. At this open. Hub structure, the fan blades go directly into the flat hub.
  • DE 100 05 857 A1 discloses an impeller, in particular for a fan set, in which the hub comprises a substantially annular wall, which is centered on the axis of rotation of the impeller.
  • the wings are connected to a circumferential outer surface bounding the annular wall of the hub.
  • the circumferential surface comprises two zones which are separated axially by the wings.
  • US Pat. No. 6,375,427 B1 discloses a fan for cooling an internal combustion engine, which has a hub structure formed as an auxiliary structure. This hub structure has both radially extending as well as diagonal and crossed ridges in order to increase the stability of the fan.
  • Such a hub structure is very complex to manufacture and is not always sufficient to compensate for vibrations of the internal combustion engine, which cause a strong excitation in the tilting and bending direction of the fan.
  • ADVANTAGES It is the object of the invention to provide a fan wheel for conveying cooling air, in particular for an internal combustion engine, which, despite its structurally simple design, offers a higher resistance to bending of the fan wheel.
  • the fan wheel for conveying cooling air, in particular for an internal combustion engine, on a hub on which a plurality of fan blades is arranged, wherein the hub has a circumferential rib structure.
  • the rib structure consists of substantially rectangular and planar ribs with an edge region which sit with its edge region on the hub and substantially tangential are aligned to the circumferential direction of the hub in its longitudinal extent, wherein they touch each other. As a result, the ribs reach a predetermined length, so that they run sufficiently close to a center of the fan wheel.
  • each newly formed rib extends from one fan blade to another fan blade.
  • the ribs are given a predetermined length, by means of which they can be guided past the center of the fan wheel.
  • the newly formed rib extends from the first fan blade to the fan blade arranged directly next to it.
  • the straight trained rib run in an alternative from the first fan blade to the next fan blade.
  • the newly formed rib of a fan blade 'runs to the third next fan blade.
  • the ribs which are flat or straight in this way, run close to the attachment points of the coupling, without crossing each other.
  • a development of the invention relates to a viscous fan, in particular for conveying a cooling air for an internal combustion engine, comprising a fan wheel, which is connected via a viscous coupling with a shaft of the internal combustion engine.
  • the fan of this viscous coupling has at least one inventive feature.
  • Figure 1 shows a first embodiment of the invention
  • FIG. 2 shows a second exemplary embodiment of the fan impeller according to the invention
  • Figure 3 shows a third embodiment of the invention
  • Figure 4 shows a fourth embodiment of the invention
  • a first embodiment of the fan impeller 1 according to the invention which has a flat, annular hub 2, on which a plurality of fan blades 3 are arranged, which extend approximately in the radial direction to the outside.
  • the attachment points 4 are shown for a viscous coupling, not shown, to which the fan 1 is fastened and via which the fan 1 is connectable to a world of an internal combustion engine.
  • On the flat, annular hub 2 different webs 5 are fixed, which are flat and rectangular and lead from a fan blade 3 for immediately following fan blade 6.
  • the webs 5 touch each other at their respective ends in the circumferential direction of the hub 2 and do not intersect. In this case, a web 5 starts approximately at the level of one of the edges of a fan blade 3 and ends approximately at the other edge of the fan blade third
  • FIG. 2 shows a fan 7, in which on the flat, annular hub 2 also approximately rectangular and planar webs 8 are arranged between the fan blades 3.9.
  • the individual webs 8 each lead from an edge of a fan blade 3 to the corresponding edge of the next but fan blade 9, wherein the webs
  • the web 8 terminating on a fan blade 3, 9 adjoins the further web 8, which of the same fan blade 3, 9 goes out, wherein between the two webs an angle is included.
  • a highly networked structure of the flat and rectangularly shaped webs 11 can be seen on the flat, annular hub 2, wherein in each case a web 11 extends from a fan blade 3 to the third closest fan blade 12.
  • a web starts at a front edge of a fan blade 3 and ends at the front edge of the third next fan blade 11, while the webs 11 cross over the extension of a web 11 4 times, the intersecting webs 11 thereby form a symmetrical structure.
  • the webs 11 are relatively close to the center, so brought to the axis of rotation of the fan 10 and ensure this sufficient rigidity.
  • FIG. 4 shows a further exemplary embodiment of the fan wheel 13, in which the flat and approximately rectangular webs 13 extend particularly close to the attachment points 4 of the viscous coupling, comprises eleven fan blades 3, which are stabilized by means of six straight webs 14 which do not intersect one another.
  • three webs extend along the half the circumference of the hub 2,
  • such a design can be combined with a classic ribbed principle of the hub 2,
  • Hub ramps can be provided or it can optionally optionally be dispensed with in the described solutions.
