Abstract
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.
Claims18
A hydromechanical wheelset control system for a rail vehicle, comprising:
- a leading wheelset;
- a trailing wheelset that is arranged in a direction of locomotion behind the leading wheelset;
- and
- a pump for providing energy for hydraulic deflection of the leading wheelset, with the pump being flanged to an end of a wheelset shaft of the leading wheelset or of the trailing wheelset and being coupled to this wheelset shaft at a drive side,
- wherein
- the leading wheelset is adapted to vary its position in an arc of a rail pair interacting with it, and
- wherein
- a wheelset control is provided that is connected to the leading wheelset and to the trailing wheelset and that is adapted to hydraulically deflect the leading wheelset in dependence on a deflection of the trailing wheelset, and
- the leading wheelset and the trailing wheelset are arranged in an undercarriage frame and a position of the leading wheelset or of the trailing wheelset in the arc of the rail pair interacting with the respective wheelset is defined by a longitudinal movement between the undercarriage frame and a respective wheelset bearing.
