Abstract
An arrangement for resilient absorption of forces, particularly for an intermediate buffer coupling of rail vehicles, has an elongated housing with a closed end and an open end, a friction device located in the region of the open end, and a resilient element in the housing, cooperating in series with the friction device and formed as a friction spring including a plurality of conical inner and outer rings cooperating with one another with interposition of a lubricant. An opening of the open end of the housing has a smaller diameter than a portion of the housing wherein the resilient element is accommodated. Two telescopable cup-shaped members are located in the housing and accommodate the rings of the friction spring. One of the cup-shaped members has a diameter exceeding the diameter of the opening of the housing and is constituted by an elastically deformable material.
