To provide a vibration control bush that ensures improved durability of a rubber elastic body. An inner pipe film portion of the vibration control has an inclined surface whose inclination angle with respect to an axis O direction is set to one degree or more and less than three degrees, and the inner pipe film portion has an end portion in the axis O direction whose thickness dimension is set to a quarter or less of a dimension in an axis O perpendicular direction from an outer peripheral surface of an inner pipe to an apex of the protruding portion. This ensures reducing a rubber elastic body to deform so as to bend (close contact) between the inner pipe film portion and the outer pipe film portion when a load in a wrenching direction is input. Accordingly, a durability of the rubber elastic body can be improved.

An elastomeric bearing includes a first race having an axis of rotation, a second race coaxially arranged relative to the first race and spaced from the first race by a gap and a bearing body in the gap connecting the first race to the second race. The bearing body is formed from a first plurality of elastomeric laminae coaxial with the first race and a second plurality of carbon fiber laminae coaxial with the first race, and the elastomeric laminae and the carbon fiber laminae alternate in a direction from the first race to the second race. The carbon fiber laminae may each include multiple sheets of carbon fibers embedded in a thermoplastic such as polyether ether ketone (PEEK).

The metal end cap includes an at least partially hollow interior and/or is formed by an additive manufacturing process.

A bearing bush for a vehicle is disclosed. The bearing bush includes an inner ring, an outer ring, and an elastomer element between the inner and outer rings. An actuator is configured to cause an application of a force on the elastomer element in a radial direction against at least one of the inner ring and outer ring to alter the rigidity of the bearing bushing. This provides a system for mechanically altering the rigidity of the bearing bush, making the bearing bush switchable between at least two rigidity states.

In a suspension bush in which an intermediate member is arranged between an inner shaft member and an outer tube member that are connected by a main body rubber elastic body, a central portion in the axial direction of the inner shaft member includes an inner bulging portion projecting toward the outer periphery, the outer tube member includes an outer curved portion concave toward the inner periphery, and the intermediate member includes an intermediate curved portion concave toward the inner periphery. The main body rubber elastic body is pre-compressed by diameter reduction of the outer tube member, an inclination angle of both axial end parts of the outer curved portion with respect to the axial direction is increased by diameter reduction of the outer tube member 14, and both axial end parts of the outer curved portion are pressed against axial end portions of the main body rubber elastic body.

An object of the present invention is to provide a vibration-damping device which enhances the durability of a rubber elastic body; and inhibits the occurrence of voids in an outer cylinder. The vibration-damping device includes: an inner cylinder; a resin-made outer cylinder arranged outside the inner cylinder in a radial direction of the outer cylinder; and a rubber elastic body connecting the inner cylinder and the outer cylinder.

Provided is a vibration control bush configured to improve durability of a rubber elastic body. The vibration control bush includes: a shaft member that includes a spherical convex portion; a tubular member that is arranged on a radially outer side of the shaft member; and a rubber elastic body that joins the tubular member and the shaft member. The rubber elastic body is joined to a first portion and a second portion of the tubular member. The first portion is positioned on the radially outer side of the convex portion, and the diameter of the inner circumferential face gradually decreases axially outward from the center. The second portion is positioned on the axially outer side with respect to the first portion, and the diameter of the inner circumferential face gradually increases axially outward.

A bearing assembly is for supporting a pivotable member and includes a laminated bearing having a generally cylindrical body with a centerline and a central bore for receiving at least a portion of the pivotable member. The body is formed of a plurality of alternating, generally tubular elastomeric and metallic laminae nested coaxially about the central axis, each one of the elastomeric and metallic laminae having opposing axial ends. At least one and preferably two thermally conductive members are coupled with a separate one of the two axial ends of one of the metallic laminae and each extends generally axially from the bearing body so as to provide a heat sink.

Provided are a cylindrical vibration isolator and an intermediate sleeve. In the cylindrical vibration isolator, an inner shaft member and an outer cylindrical member are connected by a main body rubber elastic body, and a cylindrical intermediate sleeve extending in a circumferential direction between the inner shaft member and the outer cylindrical member in a radial direction is fixed to the main body rubber elastic body. A slit penetrating axially is formed in a part of the intermediate sleeve in the circumferential direction. Both end parts of the slit are straight parts extending axially. A direct overlap margin of the straight parts on both sides in axial view is smaller than a radial thickness of the intermediate sleeve.
