Break-away cradle or sub-frame mount and retainer washer assembly

摘要

An isolator assembly ( 20 ) such as a cradle mount or a body mount assembly incorporates break-away features. An insert ( 70,70 ') includes a thinned cross-sectional region ( 100 ) or a gap/interface ( 90 ) between insert portions ( 70 a, 70 b) that allow a bolt ( 24 ) to break-away under a predetermined load in a fore direction ( 80 ) and an aft direction ( 90 ). In addition, a retainer washer ( 50 ) may have an irregular configuration such as a tear-drop or clover-leaf configuration that cooperates with the insert ( 70, 70 ') to allow the isolator assembly ( 20 ) to pull away in the negative z-direction under a predetermined load.
