A method for producing a bearing, in particular a hydraulic axle support bearing, which comprises the following steps: preassembling an inner part in an outer part with an elastomer body which is arranged in between and is reinforced by a plastic cage which at least partially bears against an inner wall of the outer part. The plastic cage is configured to radially protrude over an upper edge and a lower edge of the out part and, at the lower edge of the outer part, to project over the latter. Simultaneously calibrating the outer part and the plastic cage by constricting the outer part and the plastic cage from a respective first diameter to a respective second diameter which is smaller than the respective first diameter. After the constriction, the plastic cage projects over the upper edge of the outer part for the form-fitting axial securing of the outer part.

Method for producing a bearing, and bearing

A hydraulically damping bush bearing has an elongated inner part, and outer bush, an elastomeric damping member disposed between the inner part and outer bush and a pair of axial chambers offset from one another in an axial direction. The axial chambers communicate with one another via at least one axial channel. The bush bearing also has a pair of radial chambers that communicate via at least one radial channel. The radial chambers are disposed between the pair of axial chambers and are offset from each other in a circumferential direction. At least fluid-free damping chamber is provided between the axial.

Hydraulically damping bush bearing

A hydraulically damping bush bearing has an elongated inner part, and outer bush, an elastomeric damping member disposed between the inner part and outer bush and a pair of axial chambers offset from one another in an axial direction. The axial chambers communicate with one another via at least one axial channel. The bush bearing also has a pair of radial chambers that communicate via at least one radial channel. The radial chambers are disposed between the pair of axial chambers and are offset from each other in a circumferential direction. One of the pair of axial chambers has at least two separated first axial chambers spaced at a distance from one another in the circumferential direction.

An elastomeric bush bearing, with hydraulic damping, comprises a metallic inner part (), an elastomeric bearing element () encompassing the inner part () with a cage () for reinforcing the bearing element () vulcanized thereto. At least two chambers (), for accommodating a fluid damping medium, are separated from one another by partitions (), constructed between the bearing element (), adhesively bonded to the inner part () by the vulcanization, but are mutually connected by a damping medium channel (). A prestressing is applied to the elastomer of the bearing element (). However, the prestressing is not applied over the bearing shell (), but instead over the cage (). Calibration takes places thus by a pressure force exerted on the cage, before assembly of the bearing element () in the outer shell (), which is a deviation from the state of the art.

Hydraulically damping elastomeric bushing

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.

Bearing for a motor vehicle, with an inner partwith an outer surfacehaving a first undulated contourextending in a longitudinal direction L, an outer sleevesurrounding the inner partand having an inner surfacewith a second undulated contourextending in the longitudinal direction L, an undulated elastomer bodydisposed between the two corrugated contoursand extending in the longitudinal direction L. The elastomer bodyconnects the inner partwith the outer sleeveThe two undulated contoursdo not run equidistant relative to each other.

Bearing for a motor vehicle

A McPherson strut bearing for the upper connection of a McPherson strut in a motor vehicle has an inner part ( ) with a central through hole ( ) for accommodating the upper end of the McPherson strut. An elastomer body ( ) is arranged circularly on the outer circumference of the inner part ( ). A cage ( ) accommodates the inner part ( ) with the elastomer body. An elastic bearing body ( ) completely accommodates the cage ( ) up to a bilateral opening cross section ( ), where at least the cage ( ), the bearing body ( ) and a circlip ( ) surrounding the bearing body are divided in a plane passing through the central longitudinal axis ( ) of the McPherson strut bearing.
