Abstract (en)
[origin: EP0652148A1] Running gear with adjustable axle for double-axle rail vehicles to be used for solving the problem of providing automatic radial adjustment in bends in the track, a high degree of operational quietness in straight sections of track and of avoiding, under extreme conditions, counter-radial adjustments when there is only a small amount of installation space. According to the invention, this is achieved by the combination of the following features: an imaginary rotational and coupling point is provided in the centre of the wheel set by directly coupling the wheel set (8) by means of axle and wheel set links (1) and a compensation device (5). The vertical, lateral and longitudinal movements of the axle bearings or wheel-set bearings (2) are damped by hydraulic dampers (22) and the spring constant and characteristic in all three coordinates are adjusted by means of helical springs (10) with a defined degree of lateral rigidity with additional partial effect of elastomer padding (3). <IMAGE>
