ABSTRACT:
A bushing-sleeve combination for a vibration-isolating mounting. The bushing takes the form of a resilient, generally cylindrically shaped elastomer having a uniform-diameter axial bore. A hollow, cylindrical metal sleeve is fixed within the bore. The bushing includes an outwardly radiating flange portion adjacent one end of a cylindrical body portion, and an outside-surface-tapered portion joined to the other end of the body portion. When mounted in place, the bushing is compressed axially, and under this circumstance, the unique differential-diameter characteristics of the body portion and the tapered portion cause the tapered portion, and the lower part of the body portion, to flare and bulge outwardly in a manner seating the bushing-sleeve combination so as to assure maximum-performance behavior.
