Abstract
The invention relates to a spring element for vibration damping and/or suspension of a rail vehicle, comprising at least one elastic damping body and at least one fire-resistant cover layer arranged on the damping body, the cover layer having at least one compensation zone, wherein the compensation zone is compressed in the loaded state of the spring element such that wrinkling of the cover layer is prevented, wherein the cover layer and the damping body are inseparably connected to form a composite element. The invention further relates to a cover layer and the use of a spring element or a cover layer.
Claims24
A spring element for vibration-damping and/or springing, with at least one elastic damping body and, arranged on the damping body, at least one fire-retardant overlayer, wherein the overlayer has at least one compensation zone, where, in the stressed condition of the spring element, the compensation zone is compressed in a manner such that folding of the overlayer is prevented, and in that the overlayer and the damping body are inseparably crosslinked to give a composite element.
A fire-retardant overlayer, in particular for a spring element, wherein the overlayer has at least one compensation zone.
