Abstract
A radiator fan of a motor vehicle, in particular a main fan, contains a fan wheel which has a hub and an electric-motor rotor which is attached thereto in a form-locking manner. At least one connecting dome is formed integrally on the rotor, which connecting dome protrudes through a corresponding cutout of the hub and is deformed on the free end side in a rivet-shaped manner in order to produce the form-locking connection.
Claims14
A radiator fan of a motor vehicle, the radiator fan comprising:
- a fan wheel having a hub with a number of apertures formed therein;
- an electric-motor rotor attached to said fan wheel via a form-locking connection, said electric-motor rotor having at least one connecting dome formed integrally thereinwith, said connecting dome protruding through a respective one of said apertures in said hub and deformed in a form of a rivet head at a free end to produce the form-locking connection, said electric-motor rotor having a rotary axis;
- and
- a number of stabilizing ribs formed on a rotor side of said at least one connecting dome and being formed integral with said at least one connecting dome, said stabilizing ribs extending away from said at least one connecting dome and are in direct mechanical contact with said at least one connecting dome, said stabilizing ribs are disposed parallel to the rotary axis.

A radiator fan of a motor vehicle, the radiator fan comprising:
- a fan wheel having a hub with a number of apertures formed therein and a pot-shaped centering opening formed therein;
- an electric-motor rotor attached to said fan wheel via a form-locking connection, said electric-motor rotor having at least one connecting dome formed integrally thereinwith, said at least one connecting dome protruding through a respective one of said apertures in said hub and deformed in a form of a rivet head at a free end to produce the form-locking connection, said electric-motor rotor containing an end face having a surface with a centering ring centrally on said surface, said centering ring arching axially toward said hub and engaging in said pot-shaped centering opening in said hub;
- said hub further having a cylindrical boundary contour and a plurality of spaced apart ribs extending from said cylindrical boundary contour to said pot-shaped centering opening;
- and
- said centering ring and said pot-shaped centering opening each having a radius being smaller than a radius of said electric-motor rotor or said hub.
