Described is a device for holding, positioning and steering a set of braked and/or driven railway-vehicle wheels which are mounted at each end in axle bearings fitted in bearing housings. The bearing housings (6, 6') are positioned and steered by a connecting-rod assembly (3, 3') and held with respect to a steering unit (4), the steering unit (4) being fitted to a box (2) which is mounted by means of a spring mounting (8, 8') on the bearing housings (6, 6'). In order to save weight, the running gear does not have the usual frame. Adjustment of the wheels to the curve radius is essentially independent of the state of the track and the resulting wheel/rail contact geometry. |
