Abstract:
A rubber bearing, comprising:an essentially cylindrical inner part; a tubular outer sleeve substantially coaxially surrounding said inner part; a pressure body formed of an elastomer arranged between said inner part and said outer sleeve and connected to same by vulcanization, said pressure body having two free grooves extending, beginning from axial ends of the bearing, into an interior of the bearing in the axial direction running annularly around a bearing axis, an axial distance of said free grooves from said bearing axis and/or a width of said free grooves continuously changing cyclically, wherein a phase shift of a course between said two free grooves is provided determined by a change in a radial distance from said bearing axis and/or the width, each course following a same cycle, and strands of said elastomer of equal axial loadability in the pressure body form a cross bond such that a ratio of radial rigidity to axial rigidity is variable by setting angles of the strands forming the cross bond in relation to said bearing axis differently and/or by shaping the course of the contours of said free grooves differently.
