Abstract: A vehicle suspension system for large vehicles includes at least one elastomeric bearing. The bearing includes at least one substantially cylindrical elastomeric portion, at least one substantially frustospherical elastomeric portion, and at least one non-extensible shim disposed between and bonded to the substantially cylindrical elastomeric portion and the substantially frustospherical elastomeric portion.

Abstract: An elastomeric bushing assembly including a substantially cylindrical elastomeric bushing segment having a recessed channel manufactured into a portion of an outer surface thereof and a rigid member disposed within the recessed channel manufactured into the portion of the outer surface of the substantially cylindrical elastomeric bushing segment. The substantially cylindrical elastomeric bushing segment is configured such that it may be disposed within a first structure comprising an inner surface having edges defining a gap and the substantially cylindrical elastomeric bushing segment is configured such that it may receive a second structure comprising an outer surface. The substantially cylindrical elastomeric bushing segment is configured such that it may be disposed within the first structure comprising the inner surface having edges defining the gap such that the rigid member is substantially aligned and in direct contact with the edges defining the gap.

Abstract: A vibration damper for mounting on a structure for damping out resonance frequencies on the structure has a bushing assembly consisting of inner and outer coaxial spaced metal sleeves joined together by an intervening elastomeric member. A metal mass is secured to the outer metal sleeve of the bushing assembly and oscillates about the fixed inner sleeve upon flexing of the elastomeric member. A fastener extends through the bore of the inner sleeve for rotatably suspending the damper on the structure. An extension arm is secured to the inner sleeve and extends radially outwardly and passes between a pair of nubs formed on an outer annulus of the elastomeric member to prevent excessive rotation and erratic motion of the mass due to non-translational forces on the structure.

Abstract: An elastomeric clamp for securing an associated tubular member to another object and for isolating and dampening vibration comprises upper and lower elastomeric portions. The upper and lower elastomeric portions are joined at one end by an elastomeric hinge and near the other end by a closure means. An associated tubular member is compressively received within the opposing faces of the upper and lower elastomeric portions. The compressive force provided by the closure means deforms the elastomeric upper and lower portions about the tubular member, providing improved vibration isolation through the elastomeric nature of the upper and lower portions and hinge.
