ABSTRACT:
A rail truck (28) includes a load-bearing element; a pair of longitudinally spaced live axle wheel sets (32) arranged to run longitudinally along a rail track (34), each wheel set including a transverse axle (36) having two transversely spaced axle boxes (38) and wheels (40) inboard of the axle boxes (38), the wheels having tapered treads (40.1) for generating steering forces on rail track curves; resilient suspension cushions (42) acting between the axle boxes (38) and the load-bearing element (30) for resiliently supporting the load-bearing element (30); and a side link lever system (44) on each side of the truck (28) interconnecting the two axle boxes (38) of the two wheel sets (32) on that side, and including a side lever (46) having pivotal support on the load-bearing element (30) at a region intermediate the axle boxes (38) on that side, and links (50,52) interconnecting opposite ends of the side lever (46) with the axle boxes on that side.
The rail truck further includes a transverse link lever system (54) which interconnects the side levers (46) on the opposite sides of the truck (28), or which interconnects the axle boxes (38) of at least one of the wheel sets (32), in such a way that in use as a result of the steering forces a yawing movement in one wheel set axle (36) is transferred into an opposing yawing movement of the other wheel set axle (36).
