Abstract:
A rubber bearing with axial damping, the bearing comprising:a multipart bearing inner part, said bearing inner part having rigid sections of increased diameter at each axial end of the bearing, said rigid sections being of increased diameter compared with a middle area of said bearing inner part; a first elastomer surrounding said bearing inner part in some sections of said bearing inner part, said first elastomer being connected to said bearing inner part by vulcanization; an essentially cylindrical bearing sleeve accommodating said bearing inner parts; a channel carrier with chambers for accommodating a damping agent and at least one damping agent channel for the circulation of the damping agent between said chambers, said channel carrier comprising an inner sleeve, a second elastomer connected to the inner sleeve by vulcanization, and a channel ring surrounding said inner sleeve and surrounding said second elastomer, said channel ring being connected to said second elastomer by vulcanization, said channel carrier being arranged between said sections of increased diameter of said bearing inner part, a groove being formed into the outer contour of said channel ring and defining said at least one damping agent channel between said channel ring and said bearing sleeve, at least some of said chambers being formed in said channel carrier and some of said chambers being formed upon mounting of the channel carrier between said sections of increased diameter of the said bearing inner part in a vicinity of said axial bearing ends, said chambers in the vicinity of said axial bearing ends being connected to one another via said channel, two of said chambers being first and second middle chambers arranged on diametrically opposed sides of said inner part.
