Abstract

A running gear for rail vehicles includes a bogey, truck or vehicle frame. Three driven wheelsets are elastically supported in the frame. Longitudinal guide rods extend parallel to the longitudinal center of the vehicle for coupling rotary motions about vertical axes of the first and third wheelsets with a transverse motion of the second wheelset upon traversing curves. Each of the guide rods have first ends being pivotably secured to a bearing housing of a respective one of the first and third wheelsets and second ends pointing away from the respective bearing housing and toward the second wheelset. Bell cranks are supported on the outside of the frame and have two diagonally opposed pairs of arms pointing toward the longitudinal center of the vehicle and two diagonally opposed pairs of arms pointing toward the second wheelset. The second ends of the connecting rods are each pivotably secured to a respective one of the arms pointing toward the longitudinal center of the vehicle. Transversely extending coupling rods are each pivotably connected to a respective two of the arms pointing toward the second wheelset. Double levers are supported on the outside of the frame and extend in the longitudinal direction of the vehicle. Each of the double levers pivotably connect one of the arms of one of the diagonally opposed pair of arms pointing toward the second wheelset to the an surface of one of the bearing housings of the second wheelset.
