Rubber bearing having axial damping

Abstract

A rubber bearing with axial damping includes a multipart bearing inner part ( ), an elastomer ( ′), which surrounds the bearing inner part ( ) in some sections and is connected thereto by vulcanization, chambers ( ′) for accommodating a damping agent, a channel carrier ( ) with at least one damping agent channel ( ), which makes possible the circulation of the damping agent between the chambers ( ), as well as an essentially cylindrical bearing sleeve ( ), which accommodates the above-mentioned bearing parts. The bearing inner part ( ) has a section ( ) of increased diameter compared with a middle area ( ) of the bearing inner part ( ) at the respective axial ends of the bearing. A channel carrier ( ) with chambers ′ for the damping agent is arranged between the sections ( ) of increased diameter of the bearing inner part ( ). The channel carrier ( ) comprises an inner sleeve ( ), an elastomer ( ) connected to the inner sleeve by vulcanization and a channel ring ( ), which surrounds the inner sleeve ( ) and the elastomer and is likewise connected to them by vulcanization. At least one groove, which forms at least one channel ( ) between the channel ring ( ) and the bearing sleeve , is milled into the outer contour of the channel ring ( ). The chambers ( ′) are formed in the channel carrier ( ) and the chambers ( ) are formed during the mounting of the bearing between the channel part ( ) and the sections ( ) of increased diameter of the bearing inner part ( ) in the vicinity of the axial ends of the bearing are connected to one another via the channel ( ).
