Abstract

A rubber bearing with radical travel limitation and with a damping agent channel has an inner part with a tubular inner contour, an elastomer surrounding the inner part and connected thereto by vulcanization, and a channel carrier. The channel carrier is made of one or more plastic parts and surrounds the elastomer in some sections and is supported on the elastomer via support elements. Stop surfaces for the radial travel limitation are provided on the inside of the channel carrier. At least one damping agent channel, which connects chambers formed between the elastomer and the channel carrier for receiving a liquid damping agent, is integrated in the outer surface of the channel carrier. In the area of the chambers (7), the channel carrier (3) has recesses (9) for the discharge and the entry of damping agent. The recesses (9), connected to one another by the damping agent channel (10), are arranged on the circumference of the channel carrier (3) in the area of the support elements (8) and opposite the same. Depressions (5), for enclosing damping agent during the coming into contact of the elastomer (2) with the corresponding stop surface (4) as a consequence of an inward deflectio…
