  • Patent number: 5618076
    Abstract: In the case of a rail wheel having a wheel disk made of plastic and a tire made of metal, these are connected with one another by way of a metallic intermediate ring onto which the tire is shrunk. In this case, the wheel disk has a conical cross-sectional profile on its circumference and the intermediate ring, which is form-locking therewith, is axially divided into two partial rings with a correspondingly partially conical interior surface. The partial rings are in a mutual force-locking connection and are glued to the wheel disk. This ensures a double safety connection between the intermediate ring and the wheel disk.
