Abstract

A rubber bearing with axial damping includes a multipart bearing inner part (1), an elastomer (9, 9′), which surrounds the bearing inner part (1) in some sections and is connected thereto by vulcanization, chambers (5, 5′) for accommodating a damping agent, a channel carrier (11) with at least one damping agent channel (12), which makes possible the circulation of the damping agent between the chambers (5, 6, 7), as well as an essentially cylindrical bearing sleeve (10), which accommodates the above-mentioned bearing parts. The bearing inner part (1) has a section (2, 3) of increased diameter compared with a middle area (4) of the bearing inner part (1) at the respective axial ends of the bearing. A channel carrier (11) with chambers 5, 5′ for the damping agent is arranged between the sections (2, 3) of increased diameter of the bearing inner part (1). The channel carrier (11) comprises an inner sleeve (13), an elastomer (14) connected to the inner sleeve by vulcanization and a channel ring (15), which surrounds the inner sleeve (13) and the elastomer and is likewise connected to them by vulcanization. At least one groove, which forms at least one channel (12) bet…
