Disc wheel with ventillation passages

摘要

Wheel for motor vehicles of the type which is cast or forged in one piece and composed of a light metal alloy and possessing a rim and a wheel disc with a radial clearance between the rim and the periphery of the wheel disc. Ventilation apertures are defined by the radial clearance and radially extending connecting webs bridging same. In order to provide an outer appearance which is aesthetically pleasing and to limit soiling of the wheel by brake friction material while facilitating a strong light weight construction the ventilation apertures extend radially so they are not visible as open windows from the front, a stiffening ring at the wheel disc forms a connection base for the connecting webs, which ring is severed at spaced locations during manufacture.
