Abstract
Abstract This invention relates to a wheelset, that is a pair of railway wheels having tires fixedly connected by fibrous resin bonding materials to an axle so that they rotate with the axle. According to the invention the axle is formed by applying a resin-bonded fibrous material comprising one of, or any combination of carbon, boron, asbestos and glass fibers to an axle core, the wheels having wheel centers secured to the axle by a continuation of the fibrous material extending from the axle on to each wheel center so that the wheels and axle are an integral assembly. The wheelset is particularly applicable to railway vehicles.
