Abstract: The invention relates to an article having a main body with elastic characteristics, in particular an air spring bellows, a metal-rubber element or a vibration damper. The article has a single-layer or multilayer main body having elastic properties, wherein the outer layer C has at least two laminas C1/C2 and each lamina is formed from an elastomer mixture, and wherein at least one layer D composed of a weave or loop-formed knit or loop-drawn knit has been embedded into this outer layer. This leads to further optimization of the fire-retardant properties.

Abstract: The invention relates to an article comprising a main body (6, 7, 8) that consists of a polymer material having elastic properties, particularly an air spring bellows (2), a metal-rubber element or a vibration damper. In order for fire-retardant properties to be improved, the article is provided, partially or fully, with a cover (9) formed from at least one flat textile structure and/or at least one three-dimensional textile structure and/or at least one shrink film. The cover can be fire-retardant itself or can be equipped to be fire-retardant.

Abstract: The invention relates to an article (1) having a main body composed of a polymeric material having elastic properties, in particular an air spring bellows (1), a metal-rubber element or a vibration damper. In order to improve its fire-retardant and/or flame-retardant properties, the article has been provided partially or completely with a flock (9).

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.
