The invention relates to a wheel suspension device for vehicles (4) comprising a non- rotating shaft (6) with a shaft journal (8) and, mounted on the shaft journal (8), a wheel bearing unit (10) comprising an inner running ring (12) and an outer running ring (14) which rotates relative to the inner running ring (12), the inner running ring (12) being fixed to the shaft (6), a hub (16) fitted on the outer running ring (14), and a protective ring (24), which serves as thermal radiation shielding, comprises at least one aperture (26) and at least one protruding means (28, 30) in the form of an air deflector, is arranged fixed relative to the outer running ring (14) of the wheel bearing unit (10), extends away from the wheel bearing unit (10) in a space between the shaft (6) and the hub (16) and is adapted to rotating together with the hub (16) and the outer running ring (14) of the wheel bearing unit (10) when the vehicle (4) is in motion, which aperture (26) and protruding means (28, 30) are arranged and angled in such a way that a cooling and particle-diverting air flow (B) away from the inside (32) of the protective ring (24) is created through the aperture (26) and thereafter towards the inner surface (36) of the hub (16) situated on the outside (34) of the protective ring (24), and thereafter also away from the wheel bearing unit (10), when the vehicle (4) is travelling forwards. |
