An articulation and/or bearing device () with a pivot pin () whose head area (), in the assembled condition, is held in a receiving joint cup () and, together with the latter, can move axially relative to an accommodating space that acts as a housing (), is designed such that in relation to the axial movement of the joint cup () within the housing (), the articulation or bearing device () acts as a gas pressure spring and/or damper.

Articulated and/or bearing unit

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.

Pivoting bearing

A steering triangle () is provided for the axle suspension of motor vehicles for the articulated connection of a vehicle axle with a vehicle chassis with two control arms (). The control arms are connected to each other in a joint housing () formed by the control arms () together for a rubber-metal bearing () for fixing the steering triangle () on the vehicle axle. The rubber-metal bearing () has a pivot axis () provided with a spherical surface and an elastomer body (), which extends around the pivot axis () at least in the area of the spherical surface and which is accommodated in a recess () located within the joint housing (), in which steering triangle two pressing rings () are arranged within the recess () of the joint housing () on the axial outer sides of the elastomer body (). The pressing rings can be moved toward each other by a tensioning device via the intermediary of stop faces () of the joint housing (). The stop faces are in contact with the outer sides of the pressing rings (), which outer sides face away from each other. The rubber-metal bearing can be pretensioned both in the axial direction and in the radial direction, so that stronger forces can be absorbed due to the higher rigidity achieved as a result.

Steering triangle

An axle rocker for connecting an axleto the vehicle bodyof a motor vehicle, which has a flangeprovided at the axle, a central joint arranged at the flangeand two swivel armsandconnected to the central joint, which are pivotably fastened to the vehicle body. The central joint has a central joint housingand a central joint inner part, which is mounted pivotable in same and which protrudes from the central joint housingat its two ends designed as connection pins on two mutually opposite sides. Furthermore, at least part of the central joint housingis made in one piece with the flange, and the swivel armsandare fastened with their ends facing the central joint to the two connection pins of the central joint inner part

Axle locating rod

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

A ball joint for chassis parts in motor vehicles is described, in which a hinge pin 1 with a spherical part 2 is mounted in a housing 3 by a bearing box 4. The hinge pin is led through an opening 6 out of the housing 3. The housing 3 is sealed by a lid 7, on the opposite side. In this case, the housing is placed in a rigid external bushing 10 with an elastomer sleeve 9 surrounding the housing. Radial surfaces on the housing 3, as well as on the external bushing 10, limit the axial movement of the housing 3 with respect to the external bushing. The radial surfaces of the housing 3 are formed by the two flat sides of a collecting plate 15, which can be firmly connected to the housing 3 first in the assembly of the joint. The collecting plate 15 engages with an axial moving space between arranged radial surfaces of the external bushing 10.
