Isolation mount

Abstract

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.
