Abstract
An arrangement for resilient absorption of forces, particularly for an intermediate buffer coupling of rail vehicles, has an elongated housing with an open end and a closed end, 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 having a plurality of inner conical rings and outer conical rings cooperating with one another with interposition of a lubricant, and outer and inner cup-shaped casing members in the housing which are telescopable in one another and closingly accommodate the outer rings and the inner rings of the friction spring, of which the inner cup-shaped member has an outer diameter corresponding to the transverse dimensions of an opening of the open end of the housing, whereas the outer cup-shaped member is separated in a longitudinal direction into a plurality of parts which are tightly held together by holding elements.
