A rubber bearing, preferably a simple rubber bearing, is provided with an essentially cylindrical inner part (1), a tubular outer sleeve (2) coaxially surrounding the inner part (1), as well as a pressure body, which is an elastomer (3). The elastomer (3) is arranged between the inner part (1) and the outer sleeve (2) and is connected to same by vulcanization. Two free grooves (4, 4′) extend, beginning from the axial ends of the bearing, into the interior of the bearing in the axial direction over a complete circle around the bearing axis (5). The axial distance of the free grooves (4, 4′) from the bearing axis (5) and/or whose width continuously changes cyclically, wherein there is a phase shift between the two free grooves (4, 4′) in terms of their course, which is determined by the change in the radial distance from the bearing axis (5) and/or the width and which course preferably follows the same cycle. Strands (6, 6′) of equal axial loadability in the pressure body formed by the elastomer (3) form a cross bond, so that the ratio of the radial rigidity to the axial rigidity is variable in bearings having otherwise the same basic design by setting the angles of the strands (6, 6′) forming the cross bond in relation to the bearing axis (5) differently and/or by shaping the course of the contours of the free grooves (4, 4′) differently.
Rubber bearing, preferably a simple rubber bearing, with a said, essentially cylindrical inner part (1), a said tubular outer sleeve (2) coaxially surrounding the said inner part (1), as well as a pressure body, which consists of a said elastomer (3), is arranged between the said inner part (1) and the said outer sleeve (2) and is connected to same by vulcanization, in which two said free grooves (4, 4′), which extend, beginning from the axial ends of the bearing, into the interior of the bearing in the axial direction over a complete circle around the said bearing axis (5), and whose axial distance from the said bearing axis (5) and/or whose width continuously changes cyclically, wherein there is a phase shift between the said two free grooves (4, 4′) in terms of their course, which is determined by the change in the radial distance from the said bearing axis (5) and/or the width and which course preferably follows the same cycle, and said fibers (6, 6′) of equal axial loadability in the pressure body formed by the said elastomer (3) form a cross bond, so that the ratio of the radial rigidity to the axial rigidity is variable in bearings having otherwise the same basic design by setting the angles of the fibers (6, 6′) forming the cross bond in relation to the said bearing axis (5) differently and/or by shaping the course of the contours of the said free grooves (4, 4′) differently.
