Patent ID: 8042879

Claim:
A vehicle wheel comprising a wheel disk fabricated as a casting from lightweight metal, with a disk edge running concentrically around a wheel axis and a rim ring fabricated from steel, rotationally locked to the wheel disk and having at least one rim flange, one bead seat, a drop center well base and a well base edge, wherein the wheel disk at the disk edge has a contour which is adapted to the profile of the rim flange and the well base edge and extends over an interval defined therebetween, and against which contour the rim ring bears when the wheel disk and the rim ring are in the assembled state, clamping the wheel disk between a first pressure zone on the well base edge and a second pressure zone on the rim flange, wherein a contact zone is formed between the two pressure zones at the transition of the well base edge to the bead seat, wherein the contact zone is formed by means of a security hump on the rim ring and a circumferential stay cam on the disk edge bearing on the inside thereof, and wherein in the assembled state achieved between the contact zone on the security hump and the second pressure zone on the rim flange, no direct contact areas exist between the rim ring and the disk edge.
