A hydraulic body mount includes a first support member adapted to engage a body of a vehicle and a second support member adapted to engage the frame of the vehicle. The second support member includes a cup portion disposed radially inward of the second support surface that extends axially away from both the first support surface and the second support surface. The body mount further includes a hydraulic damping system disposed between the first support surface and the second support surface, a washer and a travel-limiting cup joined to the cup portion of the second support member. The travel-limiting cup surrounds the washer and includes a compressible limiting member that limits axial movement of the inner tube when the washer contacts the compressible limiting member.

The present disclosure relates to an hydraulic mount for coupling first second components in a vehicle. The mount has a first elastomeric member defining a first portion of a first chamber, and a second elastomeric member defining a second portion of the first chamber and a second chamber. The chambers are each able to retain fluid in a liquid seal manner. An inner tube assembly defines an opening for receiving a bolt. The elastomeric members may be fixedly secured to an outer surface of the inner tube assembly. An inner ring is fixedly coupled to the inner tube assembly at a position between the two chambers. The second elastomeric member is fixedly secured to an outer surface of the inner ring. A decoupler is fixedly disposed within the inner ring and adapted to move between rigid surfaces adjacent the first and second chambers.

Bolt through hydraulic mount with and without a decoupler

A mount having a bolt through configuration couples two components of a vehicle. The mount includes a first elastomeric member that defines a first portion of a first chamber and a second elastomeric member that defines a second portion of the first chamber and defines a second chamber. An inner tube assembly defines an opening for receiving the bolt. The first and the second elastomeric members are bonded to the inner tube assembly. An annular member is disposed between the first and the second chambers. The annular member defines a fluid-track which fluidly couples the first and the second chambers. The mount dampens vibrations at varying amplitudes by pushing fluid between the first and the second chambers via the fluid-track. The mount may also include a decoupler by way of a decoupler ring and decoupler cap to isolate the mount at a predetermined amplitude at varying frequencies.

An elastomeric bushing includes an inner component, first, second and third elastomeric or plastic members and an outer component. The first elastomeric or plastic member is disposed over the inner component. The second elastomeric or plastic member is disposed over the first elastomeric or plastic member. The third elastomeric or plastic member is disposed over the second elastomeric or plastic member. The outer component is disposed over the third elastomeric or plastic member.

A hydraulic bushing assembly includes an inner tube, an elastomeric bushing disposed around the inner tube, an insert disposed around the elastomeric bushing and an outer tube disposed around the insert. The elastomeric bushing and the insert define a pair of chambers which are connected by a passageway defined by the insert. A pair of intermediate tubes are disposed in the elastomeric bushing at opposite axial ends of the insert.

A multiple chamber piston includes a first fluid chamber and a second fluid chamber attached by a first channel and a third fluid chamber connected to a fourth fluid chamber by a second channel. Air chambers are provided between the first fluid chamber and the third fluid chamber as well as the second fluid chamber and the fourth fluid chamber. As a result, when vibration is to be attenuated, walls of the air chambers are able to bend and deform to increase compliance of the overall multiple chamber piston.

A bushing for rotatably supporting a bar-shaped suspension link comprises an elastomeric body having a central axis and including an axial bore adapted to receive the suspension link therethrough. The bore includes a circumferential surface having projected surface portions and recessed surface portions, the projected surface portions projecting radially inwardly to provide radial clearance between the suspension link and the recessed surface portions. Preferably, the projected surface portions include a plurality of first and second ridges projecting radially inwardly. The first ridges are substantially parallel to the central axis of the elastomeric body and intersect the second ridges at substantially right angles to define therebetween the recessed surface portions. The preferred embodiment of the bushing of this invention further comprises a double-knit fabric liner covering the circumferential surface of the bore of the body. The fabric liner preferably is woven from fibers of polyester and polytetrafluoroethylene and conforms to the contour of the projected and recessed surface portions of the axial bore. In addition, a method of manufacturing the suspension bushing is disclosed.
