Abstract
A mount bushing includes an outer mounting ring adapted for connection to a mount structure. An outer structural ring is disposed inside of the outer mounting ring. A main elastomeric isolation arrangement is disposed between the outer structural ring and an inner structural insert, wherein the main elastomeric isolation arrangement is supported between the outer structural ring and the inner structural insert by elastomer material. An outer ring isolation layer of elastomer is disposed between the outer mounting ring and the outer structural ring, wherein the outer ring isolation layer is isolated from the main elastomeric isolation arrangement by the outer structural ring. A mounting bolt is inserted through a bore in the inner structural insert.
