Abstract: The present invention is a spring, comprising a support structure and a substantially straight walled, solid elastomeric column. The support structure has a continuous and selectively vented support wall and a base wherein the support wall has different minimum and maximum inside diameters. The elastomeric column has a diameter less than, equal to, or slightly larger than the minimum diameter of the support structure wall and a height greater than the height of the support structure.

Abstract: An elastomeric bushing for vehicular and non-vehicular applications includes a generally cylindrical body having spaced apart end faces, an axial passageway extending through the body and the end faces, and at least one elongate void formed in a body side and located radially outward from the axial passageway. The void includes opposite lobe end portions, each configured having an elongate major axis and a shorter minor axis. The major axes of the lobe portions are canted in opposite directions away from an imaginary vertical plane therebetween. The void further includes a connective portion between the lobe portions, the connective portion having a concave shape in a radially inward direction that defines a radially outward protruding boss. The shape and location of the lobe portions and the boss protrusion are variable to provide combined optimization of the bushing performance among spring rates, articulation durability, and load capacity.

Abstract: A vehicle body mount comprised of a lower rebound mount and an upper load mount provides a method to fasten the rebound mount to the load mount in preparation for accommodation of a vehicle frame and vehicle body which may be radially eccentric mismatched. While continually maintaining the interlock function, the integral rebound mount and flexible interlock feature allows radial float of the rebound mount relative to the load mount, until the securing bolt seeks, engages, and is aligned with the body mounted nut, during assembly of the body to the frame. The rebound mount is defined by an extending interlock which is expandable at its outermost portion in order to engage the central opening of the upper load mount.
