Abstract
A bushing assembly employed in an engine mount comprises a cup-shaped outer housing, a cup-shaped inner housing having an engine support trunnion mounted therein, and an annular elastomeric bushing compressed between the cylindrical side walls of the outer and inner housings. An elastomeric pad is interposed between an end wall of the outer housing and an end wall of the inner housing to substantially absorb axially directed loads imposed thereon by the trunnion. Air openings are provided for facilitating assembly in the first embodiment in the outer housing and pad and in the second embodiment in the inner housing. In the second embodiment, the pad is spaced from the end wall of the inner housing and further includes a radially directed rib on the inner housing positioned to contact the annular member so as to assist in damping axial movement.
