Introduction

Günter Stelzer is a notable inventor based in Bad Honnef, Germany. He has made significant contributions to the field of vehicle wheel design, holding a total of four patents. His innovative designs focus on enhancing the strength and efficiency of vehicle wheels for passenger cars.

Latest Patents

Stelzer's latest patents include a vehicle wheel designed for passenger cars. This wheel features a rim part and a disc part formed from a one-piece sheet metal blank. The design includes a central portion with bolt holes and a series of radially extending spoke arrangements that merge into a disc edge. These spoke arrangements create ventilation apertures that extend over the region between the edge webs and the disc edge. The design aims to achieve high strength and stiffness with a four-hole fixing, where the spoke arrangements and bolt holes are arranged mirror-symmetrically. Each spoke arrangement narrows radially towards the outside, and the ventilation apertures extend circumferentially over a significant arc length. Additionally, each ventilation aperture has a maximum radial clear width that is equal to or greater than the radial width of the metal portion of the disc part.

Another patent by Stelzer describes a vehicle wheel that integrates a disc part with a rim part. The disc part is formed from a sheet metal blank and includes a central part with bolt holes for wheel bolts and a central hole for a vehicle hub. The design features radially extending spoke arrangements that transmit forces between the vehicle hub and the rim part. Each spoke arrangement is equipped with a central web and side webs that are bent outwards, merging into a disc rim that connects all spoke arrangements and defines ventilation holes. This innovative design allows for steel vehicle wheels with an unequal number of bolt holes and spoke arrangements, featuring concentric inner and outer annular beads.
