An arrangement for resiliently absorbing forces in various operational conditions, has a housing, a resilient element located in the housing and formed as a friction spring with a plurality of inner and outer conical rings cooperating with one another with interposition of a lubricant, and an additional body of the lubricant accommodated in an inner chamber formed inside the rings and including such a quantity of the lubricant which is sufficient for continuously replenishing the lubricant between the rings during operation of the arrangement in various operational conditions.

Arrangement for resilient absorption of forces

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.
