Shear mount

摘要

A body mount for absorbing compressive and shear forces in a vehicle is disclosed. The body mount includes a retainer member with a radial portion and an axially extending tubular portion. A microcellular bushing has base, a top, and a passageway extending from the top to the base. The axially extending portion of the retainer member is inserted into the passageway of the bushing. An insert is molded into the bushing to form a one-piece member. The insert has an inner diameter. The microcellular cylinder insert is adjacent to the axially extending tubular portion. A microcellular cylinder sleeve is formed between the inner diameter and the tubular portion and in combination with the insert resists lateral forces and does not interfere with the vertical forces from the frame to the body. The microcellular shear mount design provides excellent lateral shake isolation and excellent vertical rate dissipation over prior art rubber shear mounts.
