The invention relates to the bogie trucks for rail vehicle, in particular to ones adjusted for movement on the tracks of various width. A bogie contains at least one wheel pair with bearings located in housings on which main springs are rested. The bearings can be positioned in at least two different positions in the wheel-set bearing housing relative to the middle axle (a) of main spring in dependence on the track width of wheel pair. Required position is provided by adapter rings centered and fixed in the housing. At that there is no need to change the whole swivel truck or to use highly engineered wheel pairs with possibility of changing track width. The invention provides shortening time for readjusting the truck for movement on the track of different width. |
