Abstract
An arrangement for resilient absorption of forces, particularly for an intermediate buffer coupling of rail vehicles, comprises an elongated housing having open and closed ends, a friction element located in the region of the open end of the housing, a resilient element cooperating in series with the friction element and formed as a friction spring including a plurality of inner conical rings and a plurality of outer conical rings cooperating with one another with interposition of lubricant, outer and inner cup-shaped casing members located in the housing and closeably accommodating the friction spring. The outer cup-shaped member forms a support for one end of the friction spring, whereas the inner cup-shaped member forms a support for the other end of the friction spring. A sealing element is fitted on the outer cup-shaped member and held on the inner cup-shaped member so that the outer and inner cup-shaped members can move relative to one another in a direction of elongation of the housing, but at the same time are sealed by the sealing element.
