Abstract
The invention relates to a method for active radial control of the wheels (11, 53, 103, 108, 115) of at last one wheel unit (8, 9, 10, 51, 52) on a chassis, in particular a bogie on a tracked vehicle, whereby control movements are applied to the wheel unit (8, 9, 10, 51, 52) and an integrated regulation with control movements in at least two non-identical frequency ranges are carried out. First control movements in a first frequency range and second control movements in a second frequency range, different form the first frequency range are superimposed and applied to the wheel unit (8, 9, 10, 51, 52). The invention also relates to a device for carrying out the method.
Claims26
A method for active radial control of wheels of at least one wheel unit of a running gear of a vehicle when traveling through a curve, the method comprising an integrated control with control movements in at least two non-identical frequency ranges;
- wherein first control movements in a first frequency range are applied to achieve a quasi-static setting of said wheels and a predetermined distribution of the transverse forces acting on said wheels of said wheel units of said running gear;
- and
- second control movements in a second frequency range, different from said first frequency range, are superimposed on said first control movements and applied to said wheel unit.
A device for active radial control of at least one wheel unit of a vehicle, comprising:
- at least one actuating device connected to said wheel unit for applying control movements to said wheel unit and
- an integrated control device connected to said actuating device for controlling said actuating device,
- wherein said control device is arranged to control said actuating device to apply to said wheel unit—first control movements in a first frequency range for generating quasi-static excursions of said wheel unit corresponding to a radius of curvature of a track segment to be currently travelled along and a predetermined distribution of transverse forces acting on said wheels of said wheel units of said running gear;
- and
- in a second frequency range, which differs from said first frequency range, said control device applies to said wheel unit second control movements which are superimposed on said first control movements, said second control movements serving to generate excursions of said wheel unit for stabilising running characteristics of said vehicle.
