An elastomeric mount comprises an elastomeric body disposed around an inner sleeve and defines first and second annular voids. The first annular void extends in a first direction and the second annular void extends in a second direction opposite to the first direction into the elastomeric body. The first annular void overlaps the second annular void. An outer sleeve is disposed around the elastomeric body and spaced apart from the inner sleeve, directly engaging the elastomeric body. A ferrule is fixed to the inner sleeve. The ferrule includes a stop face spaced apart from the elastomeric body and adapted to limit relative axial movement between the inner sleeve and the outer sleeve. The ferrule includes a sidewall spaced apart from the elastomeric body and adapted to limit relative radial movement between the inner sleeve and the outer sleeve.

An elastomeric mount comprises an elastomeric body defining a first annular void encircling an inner sleeve and extending in a first direction. The elastomeric body defines a second annular void extending in a second opposite direction. An outer sleeve surrounds and is spaced apart from the inner sleeve and directly engages the elastomeric body. A first ferrule is fixed to a first end of the inner sleeve, includes a stop face spaced apart from the elastomeric body, and is adapted to limit relative axial movement between the inner sleeve and the outer sleeve in a first direction. A second ferrule is attached to the inner sleeve, includes a stop face spaced apart from the elastomeric body, and it adapted to limit relative movement between the inner sleeve and the outer sleeve in a second opposite direction.

Elastomeric mount with bi-directional axial motion control and radial travel limiter

A body mount comprises a first support member adapted to engage a body of a vehicle and a second support member adapted to engage a frame of the vehicle. The second support member includes a tubular portion disposed radially inward of a second support surface. A first elastomeric spring interconnects an inner tube and the second support member. The first elastomeric spring is positioned within the tubular portion. A hydraulic damping system is disposed on a side of the second support surface opposite the first support member and includes a housing coupled to the second support member. Second, third and fourth elastomeric springs are positioned within the housing. The second elastomeric spring and the third elastomeric spring are spaced apart by a first track. The third elastomeric spring and the fourth elastomeric spring are spaced apart by a second track.

An elastomeric bushing assembly includes an outer sleeve, a bar pin, an elastomeric bushing and a monolithic, one-piece bracket. The bar pin includes first and second opposing ends. The elastomeric bushing is disposed between the outer sleeve and the bar pin. The bracket includes a body defining a cavity and a flange. The flange radially extends from an end of the body and circumferentially extends substantially 360 degrees. One of the first and second ends of the bar pin is securely received in the cavity of the body.

Bushing snubber bracket

A hydraulic bushing assembly comprises an inner tube, a travel limiter surrounding the inner tube, a first intermediate insert, a second intermediate insert spaced apart from the first intermediate insert, and an elastomeric bushing disposed around the inner tube and encapsulating the first intermediate insert and the second intermediate insert. The elastomeric bushing at least partially encapsulates the travel limiter such that a portion of the elastomeric bushing is positioned between the travel limiter and the inner tube. First and second snubbers limit displacement of the travel limiter and define first and second fluid chamber within the elastomeric bushing. A fluid passageway defined by the elastomeric bushing and an outer tube extends between the first and second fluid chambers, wherein relative movement between the inner tube and the outer tube causes fluid transfer between the first fluid chamber and the second fluid chamber.

A bolt retainer clip for positioning a fastener and maintaining its alignment within a vehicle body mount. The bolt retainer clip includes a retainer body that has a longitudinal axis, an inside surface, and an outside surface. The inside surface defines a bolt receiving aperture in the retainer body. A plurality of fingers extend into the bolt receiving aperture from the inside surface of the retainer body. A portion of each finger is curved, creating a line contact between the fastener and each finger at a location that is spaced from a terminal end of the finger. Each line contact runs parallel to the longitudinal axis and therefore limits gimbaling movements of the fastener relative to the retainer body.

A hydraulic mount includes an inner tubular assembly, first and second elastomeric bodies and a fluid-track. The first and second elastomeric bodies are attached to the inner tubular assembly and cooperate to define a first fluid chamber. The second elastomeric body also defines a second fluid chamber that is in fluid communication with the first fluid chamber via the fluid-track. The fluid-track is attached to the inner tubular assembly partially disposed in the first fluid chamber. The fluid-track includes a central portion, a peripheral portion and a passage. The peripheral portion extends radially outwardly from a periphery of the central portion. The passage provides fluid communication between the first and second fluid chambers. Gaps are positioned between the peripheral portion and a wall of one of the first and second elastomeric bodies. The peripheral portion being configured to contact the wall during loading of the inner tubular assembly to restrict movement of the inner tubular assembly and the fluid-track.

The present disclosure is directed to a bushing assembly having a tubular inner metal, a tubular outer metal, a tubular rigid cup disposed over an outer portion of the tubular inner metal, and a tubular pad disposed between the tubular rigid cup and the tubular outer metal. The tubular pad may have a first wall section and a second wall section at least partially circumscribing the first wall section. The first wall section may be configured to be compressed and to expand along an axis parallel to an axial center of the tubular pad, to thus fill the tubular rigid cup and enhance a stiffness of the bushing assembly when the tubular outer metal of the bushing assembly is moved towards a limit of a range of radial travel.

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.
