Wheel assembly for motor vehicles

摘要

A wheel assembly is configured for suspending the wheel of a motor vehicle on one side and includes a brake disc, which is part of a disc brake and which is fixed, when viewed in the radial direction, to a wheel disc on the outer circumference of the wheel assembly in close vicinity to a wheel rim. The brake caliper of the disc brake surrounds the brake disc over the inner circumference of the brake disc and is fixed to a wheel carrier that supports a stationary ring of a wheel bearing, which has a rotating ring that supports a wheel hub that in turn is connected to the wheel disc. The invention brake disc is fastened to the wheel disc in a floating manner and/or in an elastically flexible manner in the radial direction.

1. A wheel assembly configured for suspending a wheel of a motor vehicle on one side, the wheel assembly comprising:
a brake disc, which is part of a disc brake and which is fixed, when viewed in a radial direction; a brake disc holder arranged to receive and support the brake disc in the radial direction and in an axial direction; a wheel disc extending radially outward from a wheel hub toward an outer circumference of said wheel assembly; and a wheel rim having an extruded hollow profile chamber radially outboard of the wheel disc and an integrally-formed radially-inward projecting connecting collar arranged to be fixed to radially-outer peripheral regions of the wheel disc and the brake disc holder, wherein
a brake caliper of said disc brake surrounds the brake disc over an inner circumference of said brake disc and is fixed to a wheel carrier that supports a stationary ring of a wheel bearing, the wheel bearing having a rotating ring that supports the wheel hub that in turn is connected to the wheel disc;the brake disc is fastened to the wheel disc via a rim carrier ring of the brake disc holder in at least one of a floating and an elastically flexible manner in the radial direction with a plurality of connecting segments between the brake disc and the wheel disc in the radially-outer peripheral region of the brake disc holder adjacent to the wheel rim, each of the connecting segments having a radially-oriented fold, the wheel hub is connected to a drive shaft on a side of the wheel bearing that lies inside the wheel via a Voith Hirth coupling, and the brake disc holder is elastically flexible in the radial direction and the rim carrier ring of the brake holder is located at the radially-outer peripheral regions of the wheel disc without contact with the wheel hub.
