Abstract: A slipper bushing comprises radially inner, intermediate and outer generally cylindrical members. The intermediate member includes an axial bearing surface at an end thereof. Elastomeric material is disposed between the intermediate and outer members. A generally cylindrical polymeric radial bearing sleeve is disposed between the inner and intermediate members and has a radially inner surface nonrotatably fixed relative to a radially outer surface of the inner member and a radially outer slip surface adapted to rotatably slip relative to a radially inner surface of the intermediate member. An elastomeric seal has an annular portion with opposed first and second axial bearing surfaces. The seal first axial bearing surface sealingly engages the intermediate member axial bearing surface and is nonrotatably fixed relative thereto. An annular polymeric slip ring has opposed first and second axial bearing surfaces.

Abstract: An elastomeric mount for automotive application is provided having a preassembled, sealed fluid composite with a first and a second fluid chamber connected by means of a restricted orifice. The fluid package is accepted into and supported by an upper and a lower compliance member which provide general damping of vibration and oscillation of an automotive component. Means are provided to regulate the flow of the fluid and/or the fluid flow characteristics between the first and the second chamber in response to a stimulus to selectively isolate and dampen undesired vibration.

Abstract: Briefly, according to this invention there is provided a viscous fluid mount for interconnection between a vibrating body and a base. The viscous fluid mount includes a chamber, a high viscosity damping fluid contained within the chamber and a flow resistance device. Input energy from the vibrating body is dissipated by shear friction of the damping fluid moving parallel to the shear surface area of the flow resistance device.

Abstract: A slipper bushing assembly including a series of concentric members for permitting controlled sliding movement between a support element and a movable element. The concentric members of the slipper bushing assembly include a rigid one piece inner metal member joined to the support element, a hollow cylindrical elastomeric member, a rigid, one piece hollow outer metal member, a solid slip surface and structure for preventing the inner metal member from disengaging from the outer metal member. The inner metal member has a pair of opposing ends and an outer cylindrical-like surface. The elastomeric member encircles the outer surface of the inner metal member and has a pair of opposing ends, an outer surface and an inner surface. The outer metal member is joined to the movable element and has a pair of opposing ends and an outer cylindrical surface. The slip surface is contiguous to the inner or outer surface of the elastomeric member and coextensive therewith.

Abstract: The present invention relates to a hydraulically damped powertrain mount (10) which includes an inner and outer in-series elastomeric springs (12, 14), having a cylindrical form with an oval cross section. The powertrain mount is secured to a supporting object by a flange extending outwardly from the periphery of an outer support housing (18) conforming generally to the shape of the outer elastomeric spring. Adjoining the inner and outer springs is a intermediate metal plate (16) utilized to assemble the springs concentrically in a partially nested relation therewith. A mounting member (22) is received within a centrally located recess portion formed in the inner spring and projects freely from the inner spring for attaching the engine or motor which is to be supported. A diaphragm (32) is secured to the intermediate metal plate and cooperates with the inner spring to define a fluid filled chamber. The fluid chamber is divided by a partition assembly (28) into two fluid filled holding chambers (A, B).

Abstract: A stabilizer bar bushing adapted to receive a metal stabilizer bar and to be secured within a mounting assembly that is attached to a vehicle frame for cooperatively resisting excessive sway when a vehicle is turning and a method of manufacture. The stabilizer bar bushing includes an elastomeric member and a low coefficient of friction film layer. The elastomeric member has an outer diameter, an inner diameter defining a bore and a slot extending the longitudinal length of the elastomeric member from the outer diameter to the inner diameter. The low coefficient of friction film layer is adhered to the inner diameter and the slot to facilitate ease of insertion of the stabilizer bar within the bore and reduce frictional engagement of the elastomeric member with the stabilizer bar.

Abstract: A fluid damped bushing (10, 100) comprising a metallic sleeve (12, 112) and an annular elastomeric body (14, 114) mold bonded to the exterior of the metallic sleeve. The elastomeric body has a spaced apart pair of fluid containing recesses (18, 118 and 20, 120) in its exterior surface with a serpentine shaped inertia track (26, 126) in the outermost surface of the elastomeric body to provide communication between the recesses. A window metal sleeve (16, 116) is encapsulated within the elastomeric body by mold bonding, and the window metal sleeve has a longitudinally spaced apart pair of rings (30, 130 and 32, 132) above and below the level of the recesses, respectively, and a diametrically opposed pair of webs (38, 138 and 40, 140) extending between the rings. In a first embodiment, a plurality of outwardly projecting pads (28) is located in one of the webs in the region of the inertia track to prevent deformation of the inertia track under lead.
