Abstract: A wheel for rail vehicles with at least one disc which is connected to an axle, and with a wheel rim having a tread or surface surrounding the disc, while the rail tread in engagement with the rim tread results in contacting points of the wheel during straight forward drive of the vehicle located on the tread or track of the rails. At least within that region of the rim which contains the above mentioned rail contacting points of the wheel rim the wheel rim is turnably connected to the disc for turning about an imaginary axis located in about the driving direction of the wheel.

Abstract: Articulated railway service wheel with structurally distinct rim, web, and hub. A toroidal rim is interconnected to the hub by a rod-like web defining individual spring units which respond in tension and compression to vertical and lateral loading. The spring web units are seated in rim and hub socket means which prevent relative rotational movement. A unitary hub-axle is also provided.
