Abstract
The wheel set comprises a pair of load-carrying wheels that run on a track, and that are steerable about parallel axes on a fixed portion, together with two pairs of guide wheels for bearing laterally against the track. The pairs of guide wheels are situated on either side of the load-carrying wheels, and they are carried by the same guide frame which is displaceable relative to the fixed portion only in rotation about a vertical axis. The guide frame is connected to the load-carrying wheels by a forced steering linkage for the load-carrying wheels. The fixed portion is constituted by a transverse box girder placed above the guide frame and provided with steering pivots for the load-carrying wheels, which pivots are placed beneath suspension cushions for the vehicle.
