Definitions

  • the invention relates to spare parts for vehicles, and more particularly to electric motor-fans that cooperate with the radiators of the engine cooling circuits.
  • the fans of the motor-fan units placed in front of the radiators of the vehicle engine cooling circuits are mounted on a drive plate, which itself is fitted on the shaft of the brushless motor (brushless) of the fan.
  • This solution provides a good speed of attachment of the propeller, but has the disadvantage of leading to a relatively large axial size of the device.
  • the proposed solution is not optimal from this point of view.
  • the fixing of the bowl of the propeller on the cylinder head is made by riveting.
  • the main objective is to generate a flow of cooling air between the stator and the rotor.
  • a space is provided between the stator and the bottom of the rotor yoke to allow the circulation of air.
  • this space makes it possible to maintain a safety distance between the windings of the stator and the internal protrusion of the rivets fixing the propeller on the cylinder head of the rotor.
  • This protrusion is dimensionally difficult to control, in that the riveting is blind for the inner part. It is therefore necessary to oversize the space to ensure that said uncontrolled outgrowth will not come into contact with the stator.
  • riveting is a relatively long operation, requiring a special position on the production line.
  • this method of attachment does not allow easy disassembly and reassembly of the assembly.
  • disassembly requires destruction of the connection between the rotor and the propeller.
  • the object of the invention is to provide manufacturers of vehicle accessories a group-motor-fan radiator cooling circuit as space-saving as possible in the axial direction, easy to mount, inexpensive, and preferably allowing a non-destructive dismantling of the whole.
  • the subject of the invention is a motor-fan unit for a cooling circuit radiator of a vehicle, comprising a stator, a rotor in the form of a cylinder head at least partially surrounding the stator and provided with an axis, a helix provided with blades integral with a central bowl and means for directly securing the bowl to the rotor, characterized in that the said securing means are a type maintaining a dimensional integrity between a state before assembly of the motor-fan unit and a state after assembly of the motor-fan unit.
  • said securing means allow non-destructive disassembly of the propeller.
  • Said securing means may comprise lugs formed on one of the parts selected from the rotor and the bowl of the propeller and corresponding recesses formed on the other of said parts, and an elastic clip mounted on the axis of the rotor pushing the bowl of the propeller against the rotor.
  • Said securing means may comprise screws.
  • Said securing means may comprise bolts.
  • Said securing means may comprise a bayonet.
  • the invention consists in using means for securing the bowl of the propeller to the cylinder head of the rotor which retain their original dimensions permanently, so that the relative positions of the different parts are always perfectly determined. There is therefore no need to provide an oversized safety space between the propeller and the rotor, and the overall axial size of the assembly can be reduced as much as possible.
  • these securing means comprise lugs formed on the bowl of the propeller and corresponding housings formed on the cylinder head of the rotor, as well as a clip coming on the axis of the engine to hold the propeller in position. pressing it against the rotor.
  • lugs formed on the bowl of the propeller and corresponding housings formed on the cylinder head of the rotor, as well as a clip coming on the axis of the engine to hold the propeller in position. pressing it against the rotor.
  • the positions of the lugs and the housing can be reversed with respect to what has just been described.
  • the propeller 4 is not secured to the yoke 1 of the rotor by an intermediate piece fitted on the axis 2, but is fixed directly on the cylinder head 1 of the rotor, preferably removably.
  • the bowl 5 has a central orifice 7 for the passage of the axis 2. It also has, on its face 8 facing the yoke 1, lugs 9 which, when the propeller 4 is mounted on the cylinder head 1, penetrate into corresponding orifices formed in the yoke 1 of the rotor.
  • These lugs 9 and these orifices 10 are typically four in number, offset by 90 ° on a circumference, but they can of course be more or less numerous.
  • Fixing the helix 4 on the rotor 1 is completed by an elastic clip 11 which is inserted into a groove 12 formed at the end of the axis 2 which protrudes from the bowl 5 of the propeller 4 after its in place, and tends to press the bowl 5 against the cylinder head 1 of the rotor. In this way, a separation of the propeller 4 and the cylinder head 1 is possible only by a voluntary action of the user.
  • the assembly of the motor-fan unit according to the invention is particularly fast and easy, as is its disassembly which is carried out in a non-destructive manner.
  • the lugs could be arranged on the yoke 1 of the rotor and the orifices on the bowl 5 of the propeller 4.
  • the orifices 10 could be replaced by depressions or blind holes.
  • any type of housing for the pins 9 would be suitable.
