Definitions

  • the invention relates to a ventilation device comprising a fan impeller and a drive motor of the propeller.
  • a fan propeller traditionally comprises a central hub and blades extending radially from the hub to the outside of the propeller.
  • Such a propeller is used in particular for cooling the drive motor of a motor vehicle.
  • the propeller may be placed upstream or downstream of a heat exchanger, namely a cooling radiator of the drive motor.
  • the central hub of the propeller comprises a front wall and a substantially cylindrical peripheral skirt extending from the front wall and to which the blades of the propeller are connected.
  • the front wall has a substantially annular shape and allows for example to fix the electric motor for rotating the propeller.
  • This electric motor is mounted coaxially to the hub of the propeller.
  • the motor may have an inner rotor and the central hub is generally connected to the motor drive shaft.
  • fixing is generally by screwing at the front wall of the hub of the propeller. Indeed, according to a known solution, there are three screwing means near the center of the front wall of the hub.
  • Another known solution uses locking means from the outer rotor to the central hub as described for example in the document US 2004/0126232 A1 .
  • the invention aims to at least partially overcome these disadvantages of the prior art by providing a ventilation device, allowing the attachment of the hub to the motor for driving in rotation of the propeller, offering a compact solution axially.
  • the subject of the invention is a ventilation device comprising a fan impeller and an external rotor motor for driving said propeller, said propeller comprising a central hub having a front wall and an inner lateral wall defining a receiving housing for the outer rotor, and the outer rotor having a front portion and a side wall arranged in abutment against the inner side wall of the central hub, said device further comprises latching means of the outer rotor to the central hub carried d on the one hand by the central hub and on the other hand by the outer rotor, characterized in that the latching means comprise a ring mounted on the outer rotor and provided with a plurality of elastically deformable tongs, said tongs respectively comprising a first branch arranged in abutment against the side wall of the outer rotor and a second branch arranged in abutment against the internal lateral aroi of the central hub, so as to clamp together said rotor and said hub.
  • upstream and downstream refer here to the direction of flow of the airflow.
  • the front wall of the central hub can be opened to receive the front portion of the outer rotor of the motor flush. It is no longer necessary to provide a large amount of material to define the front wall of the hub to the extent that the fixing between the central hub and the engine is no longer at this level.
  • the fastening means are provided such that the inner side wall of the hub and the side wall of the outer rotor are gripped together.
  • This system therefore minimizes the number of components and facilitates assembly operations.
  • the invention relates to a ventilation device 1 comprising a fan propeller 3 and a drive motor 5 of the propeller 3.
  • a ventilation device 1 of a cooling module of a motor vehicle engine block (not shown).
  • a cooling module generally comprises a heat exchanger such as a cooling radiator.
  • the propeller 3 may be arranged either in front or behind this cooling radiator.

  • the outer rotor 7b has a front portion 9 and a rear portion 9 'opposite to the front portion 9.
  • the terms “front” and “back” are used with reference to the flow direction of the air flow.

  • the side wall 9 "of the outer rotor 7b has an outer face intended to be in contact with the central hub 11 during assembly, and an opposite inner face oriented towards the inside of the rotor 7b.
  • the front portion 9 of the rotor 7b has through-holes 10, which are more visible on the figure 4a .
  • the brewed air flow passes through the lights 10 which allows the motor 5 to cool down.
  • These lights 10 are according to the embodiment shown substantially oblong shape.
  • the lights 10 are for example regularly distributed.
  • the propeller 3 is rotated about an axis of rotation A (cf. figure 5 ).
  • the direction of rotation of the helix 3 is shown schematically by the arrow F on the Figures 1 to 3 .

  • connection in rotation between the central hub 11 and the rotor 7b is for example obtained by complementary shape between the central hub 11 and the rotor 7b.
  • upstream and downstream refer to the direction of flow of the air flow produced by the rotation of the helix 3.
  • the front wall 17 has a substantially annular shape. This front wall 17 thus has a first internal diameter D 1 , which corresponds to the diameter of the opening 19, and a second external diameter D 2 .
  • the front wall 17 is arranged flush with the front portion 9 of the outer rotor 7b.
  • the peripheral skirt 23 has a substantially cylindrical shape. It extends from the front wall 17 downstream.

  • the inner side wall 21 defines a receiving housing for the drive motor 5 (cf. Figures 2, 3 and 6 and 7 ), more precisely for the external rotor 7b of the motor 5.
  • This inner side wall 21 has an outer face and an inner face opposite to the outer face.
  • the outer face of the inner side wall 21 is intended to be in contact with the outer face of the side wall 9 "of the outer rotor 7b to the assembly, the inner face of the inner side wall is arranged in facing relation of the peripheral skirt 23 of the hub 11.

  • the latching means 27 comprise according to the illustrated embodiment, a ring 29 mounted on the outer rotor 7b; this ring 29 is provided with a plurality of tongs 31 elastically deformable.
  • clamps 31 are for example arranged between the magnets of the rotor 7b. This arrangement allows the angular immobilization of the clamps 31.
  • the ring 29 is mounted on the rear portion 9 'of the rotor 7b.
  • the clamps 31 may be evenly distributed in a predefined angular pitch, as in the example shown in FIG. figure 8 .
  • Each clamp 31 comprises a first branch 33a and a second branch 33b.
  • the first branch 33a of a clamp 31 is arranged in abutment against the outer rotor 7b, more precisely in abutment with the inner face of its side wall 9 "( figures 3 , 4b and 9 ).
  • the second branch 33b for its part, is arranged in abutment against the central hub 11.
  • a second branch 33b of a clamp 31 is for example received in a complementary housing 35 of the central hub 11.

  • the snap hooks 37 may be carried by the second branches 33b of the clamps 31 and the housing 35 may comprise a complementary hole in which the hook 37 is engaged.
  • the second branches 33b of the clamps 31 may respectively have an end 41 substantially curved. This curved end 41 facilitates the insertion of the second branch 33b into the corresponding housing 35.
