Beschreibung
Zusammenfassung:	A damping device in a bogie of a railbound freight car has good ride properties independent of the load carried by the car by making the damping device with friction wedges of triangular cross-section, an upper surface of which confronts an adjoining load-supporting bolster beam and is joined thereto through a tertiary spring element of high stiffness in the vertical direction and of relatively low stiffness in the lateral direction. A lower surface of each friction wedge adjoins the upper side of the respective bogie suspension unit.
