Abstract

A single-thrust bearing for a shock absorber with a columnar journal projecting in the damping direction and which is sealingly surrounded by a flexible, annular-shaped membrane, whereby the membrane is secured in its rim area, which projects radially to the outside, to a supporting bearing and separates two liquid-filled working chambers from each other. The working chambers are defined in the area of the extremities which mutually oppose each other by hollow-conical bearing springs made of a rubber elastic material. The bearing springs are supported in their base area on the supporting bearing and are braced against one another by means of the journal by way of their tips which are turned away from each other.
