ABSTRACT:
A bogie for rail vehicles, in particular a driven bogie, with a bogie frame, includes two or more wheelset units each of which comprises at least one drive unit and/or brake unit. The wheeset units are connected with the bogie frame via a primary suspension. A secondary suspension connects a vehicle body with the bogie frame. A rigid connecting link extends from at least one of the wheelset units for connecting the bogie to the vehicle body. The rigid connecting link is coupled to the wheelset unit at its virtual center of rotation. Where practical, the center of rotation and the center of mass are coincident to minimize the moment of inertia of the wheelset units.
