  • Patent number: 11378152
    Abstract: 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.

  • Patent number: 11168732
    Abstract: 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.

  • Patent number: 11009097
    Abstract: 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.

  • Patent number: 10752293
    Abstract: A body mount comprises a first support member defining a first support surface adapted to engage a body of a vehicle. A second support member includes a second support surface adapted to engage a frame of the vehicle. A connector member is positioned between a cover and the second support member. The connector member includes a channel support including a channel having an inlet and an outlet. A central member is fixed to the first support member and moveable relative to the second support member. The cover and the connector member define a first chamber. The connector member and the second support member define a second chamber. The chambers are fluidly connected via the channel. The channel circumferentially extends about the central member. Movement between the central member and the second support member causes fluid to travel through the inlet, channel, and outlet to transfer fluid between the chambers.

  • Patent number: 10508701
    Abstract: A vehicle suspension bushing assembly including an inner sleeve, a bearing, an intermediate sleeve, an outer sleeve, and a bushing. The inner sleeve extends longitudinally between first and second inner sleeve ends. The bearing extends annularly about the inner sleeve, the intermediate sleeve extends annularly about the bearing, and the outer sleeve extends annularly about the intermediate sleeve. The bushing is positioned radially between the outer sleeve and the intermediate sleeve. Axial retainers extend annularly about the first and second inner sleeve ends. The axial retainers are longitudinally moveable relative to the inner sleeve. The axial retainers have a preload feature including a flange segment that is resilient and deflects from an unbiased position when the axial retainers are in an uncompressed position to a biased position when the axial retainers are in a compressed position to apply a longitudinal preload force to the intermediate sleeve.

  • Patent number: 9976620
    Abstract: 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.
