Problems solved by technology

[0005] Active systems, on the other hand, provide the best results regardless of the wheel-rail conditions and the radius of the curves being driven, but are significantly more expensive in terms of their implementation
Most known active systems also react relatively slowly, so that said system cannot perform its function correctly especially when driving over a switch

Embodiment Construction

[0050] figure 1 The basic principle according to the invention is illustrated by means of a largely simplified schematic diagram.

[0051] The hydromechanical wheel set control system 1 has a guide wheel set 2 and a follower wheel set 3 (not shown in detail), the position of which in the track can be changed via actuating cylinders 12 assigned to the wheel sets 2 , 3 . It can be seen that the two actuating cylinders 12 are relatively substantially offset in opposite directions relative to each other, which represents a path curve with a relatively small radius. A change of the actuating cylinder 12 always also results in a change of the wheel set 2 , 3 connected thereto.

[0052] The idea of ​​the invention is now to hydraulically adjust the guide wheel pair 2 as a function of the automatically performed deflection of the slave wheel pair 3 .

[0053] In order to obtain a free or elastic or adjustable slave wheel pair 3 , the two chambers of the actuating cylinder 12 belongi...

Abstract

The present invention relates to a hydromechanical wheelset control system for a rail vehicle that comprises a leading wheelset and a trailing wheelset that is arranged behind the leading wheelset in the direction of locomotion, with the trailing wheelset having the property of adopting a favorable position in an arc of an undercarriage frame interacting with it and of a rail pair. The wheelset control system is characterized in that a wheelset control is provided that is connected to the leading wheelset control system and to the trailing wheelset control system and that is adapted to hydraulically deflect the leading wheelset in dependence on a deflection of the trailing wheelset, preferably by the same amount as the trailing wheelset, but in the opposite direction.

Description

technical field [0001] The invention relates to a wheel set control system for a hydraulic machine of a rail vehicle. Background technique [0002] A large number of devices for controlling wheel sets in rail vehicles exist in the prior art, ranging from passive to fully active systems. [0003] In order to achieve sustainable use with the aid of wheel set controllers for rail vehicles, the wheelset must be able to be actively brought into so-called radial positions depending on the curve radius of the track, independent of the curve radius and the contact geometry between the wheels and the guide rail irrelevant. In a fully radially aligned position, the axes of the axles of the wheelset extend to the center of the curve formed by the track. In order to realize this with one wheel set behind the other of the chassis, the wheels must be arranged movably in the chassis. [0004] Passive or semi-passive systems for aligning the position of the wheelset are known from the pr...
