<p>Running gear for railway vehicles, which, by virtue of the particular arrangement of the damping components, improves damping, permits high travel speeds and ensures that bends can be travelled through safely. This object is achieved by means of the arrangement of the vertical and horizontal shock absorbers (3, 8) in such a way that as a result of the horizontal shock absorber (8) force a rotational deflection of the axle bearing housing (6) is produced, which rotational deflection is in turn additionally damped by the vertical shock absorber (3), the longitudinal movements of the wheel sets (9) being simultaneously damped by the horizontal shock absorber and the vertical shock absorber and this also applying to a lesser degree to the transverse movements of the wheel sets. The vertical shock absorber (3) is included in the damping characteristic of the horizontal shock absorber (8). By changing the attachment point (4) of the horizontal shock absorber (8) and thus by changing the points of intersection of the median lines of the shock absorbers and the median line of the axle bearing housing (6) in the vertical and horizontal planes by means of an attachment bracket (5) arranged in a defined manner it is possible to vary the damping ratio of the shock absorbers. The invention is suitable in particular for sets of running gear which are to be used for high-speed transport.</p> |
