LIGHTWEIGHT WHEEL SET FOR RAIL VEHICLES AND METHOD FOR MANUFACTURING A DISC WHEEL FOR SUCH A LIGHTWEIGHT WHEEL SET

摘要

A light weight wheel, especially for a rail vehicle and a method of making in which at least one disc of high strength resilient metal, steel, for example, is formed by rolling or spinning to vary the thickness thereof in respective annular regions. At least the outer margin of the disc is formed to a sleeve shape which fits inside an annular wheel rim and is connected thereto by forming the sleeve radially outwardly into undulations formed in the inside of the rim. The inner margin of the disc can be formed to a sleeve shape and be connected to a hub in the same way the outer margin is connected to the rim or, the inner margin may, itself, form the hub. The disc undulates, or inclines, in the radial direction for resilient support of the rim. A single disc can be used or two discs can be used in side by side relation for a wheel.
