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 cro ss- sectional region (100) or a gap/interface (90) between insert portions (70a, 70b) that allow a bolt (24) to break-away under a predetermined load in a fo re 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 isolato r assembly (20) to pull away in the negative z-direction under a predetermined load.
