Abstract (en)
[origin: CN112744250A] 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.
