  • Patent number: 7635117
    Abstract: A bush bearing with a radial stiffness that changes in the circumferential direction. The bearing has at least one radial web with a high radial stiffness in a first radial major load-bearing direction, and at least one pocket with a significantly smaller radial stiffness than in the region of the radial web in a second radial direction which is preferably perpendicular to the first radial direction. To achieve a large force-displacement ratio and simultaneously a soft torsion characteristic, the inner element of the bearing of the invention is formed in two parts. It consists of a metal inner sleeve and a preferably also metal bearing core received in the inner sleeve. An elastomer or a rubber contour is vulcanized on the inner surface of the inner sleeve or the outer surface of the bearing core. The inner core is oversized with respect to the inner diameter of the elastomer contour. The bearing core is pressed into the inner sleeve, but does not adhere to it.

  • Publication number: 20070290425
    Abstract: An elastomer bearing (1) has an inner part (2), an outer sleeve (4) surrounding the inner part (2) coaxially to a bearing longitudinal axis (3) defining the center of the bearing and an elastomer body (5) arranged between the inner part (2) and the outer sleeve (4). The elastomer body (5) has at least one bulge (6), adjacent to which at least one tapered section (7, 8) each is located on both sides when viewed in the direction of the longitudinal axis (3) of the bearing. The outer sleeve (4) has axial end sections with a deformation (9, 10) each directed towards the inside of the bearing. Before the elastomer bearing (1) is mounted in a motor vehicle component (11), the elastomer body (5) has recesses (12, 13) on the axial front sides of the elastomer bearing (1), and the recesses (11, 12) are filled by the elastomer body (5) up to the area of the deformations (9, 10) after the elastomer bearing (1) has been inserted into the motor vehicle component (11).

  • Patent number: 7234693
    Abstract: Bearing for a motor vehicle, with an inner part 1 with an outer surface 7 having a first undulated contour 10 extending in a longitudinal direction L, an outer sleeve 2 surrounding the inner part 1 and having an inner surface 11 with a second undulated contour 14 extending in the longitudinal direction L, an undulated elastomer body 6 disposed between the two corrugated contours 10, 14 and extending in the longitudinal direction L. The elastomer body 6 connects the inner part 1 with the outer sleeve 2. The two undulated contours 10, 14 do not run equidistant relative to each other.
