Definitions

  • the present invention relates to an axial fan and in particular an axial fan for a radiator module in a motor vehicle.
  • a common axial fan for a radiator module of a motor vehicle shows the document EP 1 892 421 A2 ,
  • This axial fan is equipped with a hub for connecting the fan with an electric drive motor, which is formed substantially pot-shaped and has a frontal area and a substantially cylindrical peripheral portion.
  • an electric drive motor which is formed substantially pot-shaped and has a frontal area and a substantially cylindrical peripheral portion.
  • the connection is made torsionally soft.
  • the disadvantage of a relatively large length remains. This is contrary to the demand for ever flatter cooler modules.
  • FIG. 12 shows a motor driven fan assembly wherein a hub extends a plurality of fan blades radially extending therefrom for air cooled brushless motor for rotation such that the hub is rotatably driven by the motor.
  • pole wheel and fan wheel form the same area.
  • the present invention thus sets itself the task of providing an axial fan for a particularly flat radiator module and proposes to solve an axial fan with the features of claim 1 before.
  • a first embodiment of an axial fan comprises an electric motor 1 with a rigidly coupled fan wheel 6.
  • the fan wheel 6 is rigidly connected to the rotor 2 of the electric motor 1 for this purpose.
  • To this compound contribute various tabs of the fan 6, a plurality of retaining tongues 3 of the flywheel 2, various recesses 4, 5 in the flywheel 2 and a number of mounting screws 9, in the manner described in detail below.
  • the fan wheel 6 has a cylindrically shaped inner region, which is provided to receive the cylindrical-top-shaped pole wheel 2 of the electric motor 1.
  • the fan 6 is in the axial direction against a plurality of distributed over the circumference of the flywheel retaining tongues 3.
  • the respective contact surfaces are preferably in a direction perpendicular to the axis of rotation extending plane, which is offset behind the surface of the bottom portion of the flywheel 2 back.
  • a number of slotted cover tabs 7 on the fan 6 is provided to cover the conditional by the manufacturing process recesses 4 next to the retaining tabs 3 and to prevent the entry of foreign bodies in the interior of the electric motor 1. Furthermore, a number of strong trained driving lugs 8 on the fan 6 is provided. These drive lugs 8 engage in a number of second recesses 5 in the rotor 2. This causes a twisting of the fan 6 in proportion prevents the flywheel 2. An unintentional release of the fan 6 of the flywheel 2 is avoided by three mounting screws 9. Preferably, these fastening screws 9 are arranged as shown in the drawings within the contact surfaces between the retaining tabs 3 and the fan 6.
  • second embodiment of an axial fan according to the invention are according to the Fig. 4 and 5 the retaining tongues 3 'in the region of the edge of the pole wheel 2' arranged. Accordingly, the corresponding contact surfaces are located on the underside of the fan 6 '.
  • the first recesses 4 caused by the manufacturing method in the first embodiment are omitted here. Accordingly, no Abdecklaschen need to be provided.
  • the transmission of the torque is effected by a larger number of smaller driving lugs 8 ', which engage in recessed recesses at the edge of the bottom portion of the pole wheel 2'.
  • the retaining tongues 3 can be created by running in the bottom region C-shaped sections, the interior of which is turned to the outside.
  • the retaining tongues 3 of the pole wheel 3 are formed by a sectionally cut waistband area.
