  • 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: 7025344
    Abstract: A rubber mount, preferably a stabilizer mount, and a process are provided for mounting the mount, which is used to mount sectional bars used preferably as stabilizers. The mount is of a simplified mounting type. For this purpose, the elastomeric mount body (2) for receiving the sectional bar as well as a clamp (3) for jointly fastening the mount (1) and the sectional bar to other components forms a structural unit according to the present invention already before the mounting on the sectional bar. Both the mount body (2) and the clamp (3) receiving it have an axially extending opening gap (5). The mounting of the mount (1) on the sectional bar is carried out using the opening gap (5) by pressing the sectional bar through this opening gap into the mount (1), i.e., the mount (1) is clamped on the sectional bar.

  • Patent number: 6997614
    Abstract: An elastic rubber bearing is provided with an intermediate tube, namely, a bush bearing with a reinforcing insert arranged in the elastomeric bearing body. The design of the bearing includes a pretension, which is distributed as uniformly as possible both in relation to the circumference and in the axial direction. The pretension is generated in the elastomer in a bearing body after the vulcanization by calibrating the outer sleeve. A reinforcing element of the bearing includes an intermediate tube slotted on two sides in relation to its axial extension.

  • Patent number: 6341915
    Abstract: A rubber-mounted ball-and-socket joint with stress-optimized bearing geometry is provided. The bearing geometry of a ball-and-socket joint mounted in a rubber-metal bearing is changed such that a sufficiently great pivot angle is guaranteed for the pivot pin and the surface of the elastomer is enlarged at the same time to prolong its life. The bearing is extended beyond the radius of the joint ball on its side located opposite the pivot pin projecting from the bearing. The fulcrum point of the bearing and the fulcrum point of the pivot pin mounted in the inner part having an offset in relation to one another in the axial direction, wherein the inner and outer parts of the bearing are conically expanded. The rubber-mounted ball-and-socket joint may have, on at least one side, at least one insert with a Shore hardness lower than that of the elastomer. The insert may be inserted into the elastomer.

  • Patent number: 6007061
    Abstract: An upper MacPherson strut step bearing for wheel suspensions in a motor vehicle. The MacPherson strut step bearing includes a metallic housing that is pot-shaped in the vertical section, a rubber buffer arranged in the housing, and a support piece, which can be connected to a shock absorber and protrudes with radially extending projections into the rubber buffer that is rigidly connected to it. A radially directed housing flange forms an abutment for an annular spring buffer made of an elastomeric material, against which the top end of a coil spring of the MacPherson strut, which coil spring surrounds the shock absorber, is supported. Recesses, which influence the axial damping characteristic of the MacPherson strut step bearing, are provided in the spring buffer. The metallic housing is connected to a cover plate, which passes over at the outer wall into a jacket ring, which is directed downward and projects beyond the spring buffer.

  • Patent number: 5520465
    Abstract: A plastic bearing for stabilizers in motor vehicles, which includes two half shells, which are connected to one another in one piece on a longitudinal side by a web, and whose longitudinal edges touch each other in the assembled state. The two half shells have, on the side of their web connection, one of two guide elements, which guide the half shells into the predetermined closed position during assembly. As a result, the two half shells can be vulcanized in a mold in a position in which they are swung open by 180.degree..
