A joint and/or bearing arrangement () with a pivot pin (), in particular with a pivot pin () having a head region () which is movable with respect to a receiving joint socket (), wherein the pivot pin () is at least partially surrounded by a circumferential sealing collar (), is configured so that the outside of the sealing collar () is covered by a separate protective cover () which conforms to the shape of the sealing collar.

Pivot arrangement

A pivoting bearing for chassis components of motor vehicles has a tubular joint housing (), which forms a cylindrical interior space and in which a metallic internal part () and an elastomer body () are accommodated. The elastomer body () is axially pretensioned in the axial longitudinal direction via the intermediary of stop rings (), which are connected with the elastomer body and cooperate with corresponding projections (), which project into the interior space of the joint housing (). At least one of the projections is formed by a spring lock washer (), which is inserted into a radial depression () of the interior space of the joint housing () and is in contact with a recess (). The recess extends circumferentially radially at the outer edge of the stop ring () and is engaged by the spring lock washer () in the mounted state of the pivoting bearing.

An axle suspension for rigid axles of vehicles, especially air-cushioned utility vehicles includes a twistable fur-point connecting rod ( ) connected above the vehicle axle ( ) to the (vehicle axle ( ). The twistable four-point connect rod ( ) is connected to the vehicle chassis ( ) via two said joints ( ) each, which are arranged at spaced locations from one another in the longitudial direction of the vehicle. At least one spring assembly unit ( ) per vehicle side is located for spring suspension between the vehicle axle ( ) and the vehicle chassis ( ). An axle strut ( ) for axle guiding, extends approximately in the middle of the vehicle in the longitudinal direction of the vehicle and connects the vehicle axle ( ) to the vehicle chassis ( ) in a vertically movable manner.

Axle suspension for rigid axles of vehicles

An axle suspension of rigid axles is presented, on the axle body ( ) of which a steering triangle ( ) as well as two longitudinal control arms ( ), which are located at spaced locations from the steering triangle and have different vertical positions, and additionally a stabilizing device ( ) are arranged. The steering triangle has two control arms ( and ), which form an angle with one another and are fastened to a central joint ( ), on the one hand, and are connected to the vehicle body via a guiding joint ( and ) each, on the other hand. The following geometric axes of coordinates are defined on the axle suspension: a first horizontal axis ( ), which extends in the transverse direction of the vehicle and forms the central axis of the axle body ( ) at the same time as well as a second horizontal axis ( ), which extends in the center of the vehicle and in the longitudinal direction of the vehicle and intersects the axis ( ) at right angles and a vertical axis ( ) intersecting the intersection of the horizontal axes ( and ). The central joint ( ) of the steering triangle ( ) is mounted on the axle body with an offset from at least one of the axes ( through ).

A pivoting bearing for mounting pull rods in motor vehicles, which includes a metallic housing (2) with a cylindrical inner jacket, a metallic inner part (1), and an elastomer body (3) arranged between the housing (2) and the inner part (1). The elastomer body (3) compensates axial, radial, and cardanic movements of the housing (2) in relation to the inner part (1) by molecular deformation. The elastomer body (3), which cooperates with the cylindrical inner jacket of the housing radially in the outward direction, is arranged adheringly on the inner part (1) and is pre-tensioned axially between plate rings (4, 5). The external diameter of the plate rings (4 and 5) is undersized compared with the internal diameter of the inner jacket of the housing. A sliding surface is obtained on the cylindrical outer jacket of the elastomer body under the axial pre-tensioning of this. This sliding surface permits rotary movement of the inner part (1) in the housing (2).
