  • Hydraulic body mount with compressible bumper
    Patent number: 10442469
    Abstract: 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.
    Type: Grant

  • Hydraulic bushing
    Patent number: 8038132
    Abstract: 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.

  • High compliance multiple chamber piston for fluid damped elastomer devices
    Patent number: 6698731
    Abstract: 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.
