Beschreibung
Zusammenfassung:	Damping device in a bogie for a railbound vehicle, especially for freight cars. To achieve good ride properties in a car independent of the load carried, the invention proposes inclusion of a damping mechanism which comprises friction wedges (30) of triangular cross-section upon whose upper surface an adjoining load-supporting bolster beam (24) acts through a tertiary spring element (46) of high stiffness in the vertical direction and of relatively low stiffness in the lateral direction and whose lower surface (36) adjoins the upper side of the suspension unit (20).
