An isolation mount for use in motor vehicles in which the mount is sandwiched between the subframe and body. The mount includes an elastomeric upper mount and lower mount and a threaded fastener drawing the two elastomeric mounts together. The upper mount has an insert member with an oblong shape in the lateral displacement direction of the vehicle. The oblong shape increases the volume of elastomer that can be used to respond to lateral forces and reduces the stresses developed on the elastomer. The lateral response rate is stiffer than the fore and aft response rate and both are stiffer than the vertical response rate.

Isolation mount

An engine mount bushing for use on a motor vehicle. The bushing includes a hard case, and a core located within that case. The bushing further includes an elastomer isolator contacting the core and case. The bushing also includes a foamed elastomer isolator contacting the core, the case and the elastomer isolator.

Foamed elastomer engine mount isolating bushing

An isolation mount for use in a motor vehicle is disclosed. The motor vehicle has a body portion and a subframe portion. The subframe has a through hole. The isolation mount includes a thimble member having a flanged portion and an axially extending tube portion. An annular foamed elastomeric member is adjacent to the thimble member. The annular member having a radially outwardly extending one end portion, an opposite end portion and an inner passage. The opposite end portion is acceptable in a slidable fit into the through hole from one side of the subframe portion to the other side. The opposite end portion being movable radially outwardly when the opposite end is axially advanced past said through hole and said one end portion being axially advanced to be adjacent to the one side of the subframe portion. The length of the annular member is related to the length of the through hole so that when the tube portion is inserted into the inner passage at the opposite end portion, the thimble member advances axially toward the one end and the flanged member compresses the radially outwardly potion until the end of the tube portion is adjacent to the one end portion of the annular member. Optionally, a rubber bushing member is disposed around the axially extending portion to improve the stiffness and the stiffness rate in the lateral and fore and aft directions.

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.
