Abstract

A hydraulically damping bush bearing is presented, in which an inner rubber mount, which comprises an essentially cylindrical or nearly cylindrical inner part (1) with an axial through hole (2), an outer sleeve (3) surrounding the inner part (1) as well as an elastomeric damping member (4), which is arranged between the inner part (1) and the outer sleeve (3) and is connected to them by vulcanization, is surrounded at its axial ends by chambers (5, 5′) for receiving a fluid damping agent, wherein the chambers (5, 5′) are formed by a hydraulic area, which is arranged separately around the rubber mount and which comprises a rigid channel carrier (6) pushed over the outer sleeve (3) of the rubber mount with a channel (7) for the flow-conducting connection of the chambers (5, 5′), an outer bush (8) supported axially on the channel carrier, and means (9, 9′) arranged axially on both sides of the rubber mount for closing the bush bearing, wherein the means (9, 9′) consist in their radially outer area of an elastomer, into which a support ring (12, 12′) is vulcanized, via which the outer bush (8) is supported at the channel carrier (6).
