Abstract: A mount assembly for attaching a cradle to a vehicle frame includes an inner sleeve. The inner sleeve defines an inner sleeve aperture having a first aperture portion having a first diameter and a second aperture portion having a second diameter. The mount assembly also includes a bushing having a bushing body and configured to extend through the first aperture portion. The mount assembly additionally includes a fuse fixed to the bushing body to separate the first and second aperture portions. The mount assembly also includes a fastener configured to extend through the bushing body and an aperture in the vehicle frame for attaching the cradle to the frame. The fuse is configured to separate from the bushing body under a predetermined load to permit the fastener to shift from the first aperture portion to the second aperture portion and the cradle to shift relative to the frame.

Abstract: A releasable joint configured to attach a cradle to an underbody of a vehicle subjectable to an external force includes a fastener, an attachment portion of the cradle, and a partial sleeve. The fastener attaches the cradle to the underbody. The attachment portion of the cradle encircles the fastener and includes a breakaway portion that fractures when the external force exceeds a threshold force. The partial sleeve is attached to and disposed within the attachment portion of the cradle and partially encircles the fastener so as to form an opening that provides a horizontal pathway for the fastener to move through to exit the cradle when the breakaway portion fractures. The cradle may separate from the underbody at the releasable joint with no vertical motion of the cradle relative to the underbody when the external force exceeds the threshold force.

Abstract: An engine mount assembly includes a frame member and a cradle member. The frame member defines a frame hole and the cradle member defines a cradle hole. A bolt fixedly mates the frame member to the cradle member. The bolt has a bolt body, which is disposed within the frame hole and the cradle hole, and a bolt flange oriented downward relative to the vehicle. A well is defined by the frame hole or the cradle hole. The well is a volume around the bolt body capable of retaining water in contact with the frame member and or cradle member. A washer, having an interior hole and a perimeter edge, is disposed between the bolt flange and the well. At least one channel is defined in the washer and provides fluid communication between the well and the perimeter edge.
