Abstract
A rubber-metal spring unit is for use in bogies of rail vehicles, wherein the rubber-metal spring unit is arranged between an upper connection element, which is connected to the sprung mass, and a lower connection element, which is connected to the unsprung mass. The rubber-metal spring unit is configured as a conical layered spring composed of multiple alternately and concentrically arranged layers of elastomer material or rubber, on the one hand, and metal, on the other hand. The individual layers are formed as conical annular-shaped bodies, wherein the two conical surfaces of at least one of the conical annular-shaped bodies have different cone angles in relation to the common vertical axis of the concentric layers of rubber and metal which form the conical layered spring.
