Abstract
A wheel is provided for a commercial vehicle which comprises a wheel disk having bolt holes in the region of the wheel mounting face for attaching the wheel disc to a wheel hub flange or to a brake drum by way of wheel bolts and intermediate disks surrounding the bolt holes directly and concentrically and which by themselves provide a support surface between wheel mounting face wheel hub flange or, respectively, brake drum or dual wheel. The intermediate disks allow to avoid fretting corrosion in the support region of the wheel disc, stiffening of the wheel disk central region, avoiding of surface damage, and improvement of the bolting. The intermediate disks can be solidly attached to the wheel disk by way of adhesive disposed in between, by friction setting, or by casting.
