Abstract: A hydraulic bearing bushing (1) having:—an annular rubber body (3) that comprises an inner bushing (2) for receiving a bearing journal (12),—an outer annular housing (6) against the inner circumference of which the annular rubber body is supported, —at least two chambers (7, 8) that are formed between the annular rubber body and the annular housing or within the rubber body, are able to be filled with a hydraulic fluid and are connected together via at least one equalizing and throttle channel (9) such that, when the inner bushing is loaded by bearing forces, hydraulic fluid is exchangeable between the chambers. Reinforcing members (13, 14) having a greater modulus of elasticity in relation to the rubber material are arranged in or on the annular rubber body such that, when there is a pressure increase in one of the chambers, an expansion of the rubber body corresponding to an inflation or a change in shape is able to be reduced at least in one direction.

Abstract: An elastomer spring, particularly for rail vehicles, comprises a core made of metal or plastic; an outer sleeve that also consists of metal or plastic; a cushion made of elastomer material, in the form of a layered spring that is arranged between the core and the outer sleeve; as well as a base chamber that is configured below a core offset. The elastomer spring is configured in multiple steps in the vertical direction X, specifically consisting of at least a first spring and a second spring, whereby a chamber is present between two springs, in each instance.
