Fuel tank coupling assembly

摘要

A fuel tank assembly includes a fuel tank and a coupling assembly for coupling the fuel tank to the underbody of a vehicle. The fuel tank includes a tank body and a plurality of tabs extending from the tank body. Each tab has a tab opening. The coupling assembly includes at least one strap partially surrounding the fuel tank. The strap defines a strap opening. The coupling assembly further includes at least one fastener extending through the strap opening and the tab opening. Further, the coupling assembly includes a compression sleeve partially positioned in the tab opening. The compression sleeve defines a sleeve opening for receiving the fastener. The compression sleeve has a height that is greater than the height of each of the tabs in order to attenuate the transfer of tensile loads from the at least one strap to the tabs.
