A passive-intermodulation-mitigating mounting assembly for a fixture, such as can be affixed to a utility or communications monopole can include a first bracket and a second bracket respectively defining a first through hole and a second through hole. In some examples, a mounting plate supports an antenna or a radio. A fastener can extend through the first through hole and the second through hole, for instance to couple the first bracket with the second bracket to attach the mounting assembly to a fixture. The passive-intermodulation-mitigating mounting assembly can include a bushing that can be inserted into a through hole, and the bushing can physically and electrically isolate the fastener from one or more of the brackets. The isolation of the bushing helps inhibit the passive-intermodulation of the mounting assembly when the fastener extends, via the first bushing, through at least one of the through holes.

A rubber-metal sleeve bearing includes an outer sleeve having a first outer edge and a second outer edge in opposing relationship to the first outer edge, when viewed in an axial direction. The first and second outer edges each have at least one section provided with radially inwardly recessed outer edge regions. An inner sleeve is disposed in concentric relation to the outer sleeve, and an intermediate sleeve is disposed concentrically between the outer and inner sleeves and connected to the outer sleeve via a first elastomer layer and to the inner sleeve via a second elastomer layer.

A flexible joint for attachment to a suspension link. The flexible joint includes a housing. The housing includes an external surface and an internal surface. The flexible joint also includes a flexible joint insert. The flexible joint insert includes an inner sleeve. The inner sleeve includes a channel, where the channel is configured to receive at least a portion of an external device, and an external surface. The flexible joint insert also includes an inner elastomer. The inner elastomer is fused to at least a portion of the external surface of the inner sleeve. The flexible joint insert further includes an outer elastomer. The outer elastomer is harder than the inner elastomer. An interface between the inner elastomer and the outer elastomer is fused and a portion of the outer elastomer is in contact with the internal surface of the housing. The outer elastomer is not permanently attached to the housing.

A performance-variable bushing includes an inner support element and an outer support element. An elastomeric connecting element extends between and operatively connect the inner and outer support elements such that a substantially fluid-tight seal is formed therebetween. The elastomeric connecting element can be at least partially formed from one of an electrorheological elastomeric material and a magnetorheological elastomeric material. The performance-variable bushing includes a variation-inducing element operatively associated with the elastomeric connecting element and selectively operable to vary values of one or more physical properties of the elastomeric connecting element. The elastomeric connecting element is configured for use under a pre-load force from pressurized gas within a spring chamber of an associated gas spring and damper assembly. Gas spring and damper assemblies and suspension systems are also included.

A disc brake for a commercial vehicle has a caliper that straddles a brake disc. The caliper is mounted on a brake carrier on the vehicle side by way of two connecting bearings in an axially displaceable manner in relation to the brake disc. The connecting bearings each include a guide bar that is securely connected to the brake carrier and guided in a slide bearing of the caliper for the axial displacement thereof. At least one connecting bearing is provided with a radially elastic damping bushing, which at least surrounds the guide bar in regions and has grooves that are laterally delimited by ribs. The disc brake is designed such that the damping bushing has a progressive damping behavior in the radial loading direction.

An elastomeric bushing for a bearing. The bushing can, even after installation in the bearing, be pretensioned or calibrated, by displacement of elastomeric material in the interior of the bushing, where the displacement is carried out by different pressing mechanism and tensioning mechanism in the bushing and/or in the surrounding bearing.

A bushing includes a body and a plurality of lobes extending radially outward from the body. The plurality of lobes may include a first lobe, a second lobe, and a third lobe. The third lobe may include a material with a lower coefficient of friction than a material of the first lobe and the second lobe. A bushing assembly may include an inner member, an outer member disposed, and a bushing disposed at least partially between the inner member and the outer member. The bushing may include a first lobe, a second lobe, and a third lobe. The third lobe may include a material with a lower coefficient of friction than a material of the first lobe and the second lobe.

A strut mount includes an inner member, an outer member, and a body rubber. A stopper rubber which protrudes outward in an axial direction is disposed on the body rubber. The outer member includes a supporting portion which covers the stopper rubber from outside thereof in the axial direction. The stopper rubber includes a pedestal protrusion portion which protrudes outward in the axial direction from the inner member and a tip protrusion portion which protrudes outward in the axial direction from the pedestal protrusion portion, contacts the supporting portion, and has an elasticity in the axial direction lower than that of the pedestal protrusion portion. The pedestal protrusion portion and the tip protrusion portion taper outward in the axial direction.

It is provided a vibration damper system for a steering wheel arrangement of a motor vehicle, which is provided for arrangement on a steering wheel element of the steering wheel arrangement. The vibration damper system comprises a vibration damping mass for damping the vibration of the steering wheel arrangement, an elastic bearing element which comprises a fastening element for fastening the elastic bearing element to one of bearing element and vibration damping mass, and a fastening means for fastening to the other of steering wheel element and vibration damping mass, wherein the elastic bearing element sectionally rests against the fastening means.

A compressible bushing includes an end having a first outer diameter. The compressible bushing also includes a bumper section having a second outer diameter greater than or equal to the first outer diameter and may include of a compressible material. The compressible bushing also includes an opening passing through the end and the bumper section, the opening having an inner diameter.
