The invention relates to a regulating device for a working machine of the kind which comprises at least four rubber wheels (2) as well as a railway wheel unit (6, 7) in the area of a forward and rearward end, respectively, of the working machine, which each comprises at least two railway wheels (8) and of which at least one can be raised and lowered by means of at least one power generating means (14) to allow raising of the railway wheel unit as well as lowering of the railway wheel unit for bearing of the railway wheels against rails (9) of a railway track during simultaneous bearing of also the rubber wheels against the rails for driving of the working machine on the railway track by guiding along the rails by means of the railway wheels and driving as well as breaking against the rails by means of the rubber wheels. The regulating device comprises a position regulating device by means of which the power generating means (14), in a driving position, is automatically controllable to maintain the railway wheels (8) on a predetermined perpendicular distance (a, b) from an arbitrary rerence point on the chassis of the working machine. The invention also relates to a railway wheel device, a working machine and a method for regulating the railway wheel unit. |
