Abstract: A body mount for use in motor vehicles in which the mount is sandwiched between the subframe and body. The mount has an insert member with an oblong shape in the lateral displacement direction of the vehicle. The insert member is surrounded by a microcellular urethane body. The oblong shape increases the compression of the microcellular urethane body that can be used to respond to lateral forces. The lateral response rate can be stiffer than the fore and aft response rate. The isolation mount also can facilitate fine tuning thereof by selectively indenting a cup member surrounding the microcellular urethane body to adjust the vibration characteristics of the body mount.

Abstract: A suspension top mount is provided with vibration isolating properties by using a rigid insert combined with a stiff elastomer and a soft elastomer to provide tunable combinations of stiffness and damping.

Abstract: 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.
