A cargo management system is described having a slide bushing supported cargo shuttle. The cargo shuttle includes an aft bushing slide plate and a forward bushing slide plate. The cargo shuttle also includes an aft wedge positioned between the top surface and the aft bushing slide plate. The cargo shuttle also includes a forward wedge positioned between the top surface and the forward bushing slide plate. The cargo shuttle also includes a top surface configured to be displaced upward as a first force is applied to the aft wedge and a second force is applied to the forward wedge. The cargo management system also includes an aft shuttle drive belt coupled to the cargo shuttle and a forward shuttle drive belt coupled to the cargo shuttle.

The cargo management system of claim 1, wherein the slide bushing supported cargo shuttle includes: an aft translating lift beam coupled to the aft wedge;a forward translating lift beam coupled to the forward wedge;an aft shuttle draw bar coupled to the aft translating lift beam and the aft shuttle drive belt; anda forward shuttle draw bar coupled to the forward translating lift beam and the forward shuttle drive belt. 3. The cargo management system of claim 1, wherein the aft wedge includes 4 aft wedges and the forward wedge includes 4 forward wedges. 4. The cargo management system of claim 1, wherein the top surface is configured to be displaced less than 6.35 mm. 5. The cargo management system of claim 1, wherein: the aft shuttle drive belt is configured to apply aft-ward force to the slide bushing supported cargo shuttle;the forward shuttle drive belt is configured to apply forward force to the slide bushing supported cargo shuttle;the slide bushing supported cargo shuttle is adapted to move aft-ward in response to more aft-ward force being applied to the slide bushing supported cargo shuttle than the forward force being applied to the slide bushing supported cargo shuttle; andthe slide bushing supported cargo shuttle is adapted to move forward in response to more forward force being applied to the slide bushing supported cargo shuttle than the aft-ward force being applied to the slide bushing supported cargo shuttle. 6. The cargo management system of claim 1, wherein: the slide bushing supported cargo shuttle includes an aft bushing slide plate positioned beneath the aft wedge and a forward bushing slide plate positioned above the wedge; andthe top surface is configured to be displaced upward in response to the aft wedge being moved aft-ward between the top surface and the aft bushing slide plate and the forward wedge being moved forward between the top surface and the forward bushing slide plate. 7. The cargo management system of claim 6, wherein: a first aft bushing is positioned between the aft bushing slide plate and the aft wedge;a second aft bushing is positioned between the top surface and the aft wedge;a first forward bushing is positioned between the forward bushing slide plate and the forward wedge; anda second forward bushing is positioned between the top surface and the forward wedge. 8. The cargo management system of claim 1, further comprising a floor panel having a plurality of bushings. 9. The cargo management system of claim 8, wherein the plurality of bushings are self-lubricating polymer bushings. 10. The cargo management system of claim 8, wherein the slide bushing supported cargo shuttle is adapted to move forward or aft-ward over the plurality of bushings. 11. The cargo management system of claim 1, further comprising: an aft shuttle drive unit coupled to the aft shuttle drive belt and configured to apply aft-ward force to the aft shuttle drive belt; anda forward shuttle drive unit coupled to the forward shuttle drive belt and configured to apply forward force to the forward shuttle drive belt. 12. The cargo management system of claim 1, further comprising support beams configured to receive cargo, wherein in response to the slide bushing supported cargo shuttle being positioned beneath the cargo and the top surface being displaced upward, the top surface lifts the cargo from the support beams. 13. The cargo management system of claim 1, further comprising: an aft spring and damper assembly that is configured to apply forward force to the aft wedge; anda forward spring and damper assembly that is configured to apply aft-ward force to the forward wedge. 14. A slide bushing supported cargo shuttle comprising: an aft bushing slide plate;a forward bushing slide plate;a top surface adapted to be displaced upward;an aft wedge positioned between the aft bushing slide plate and the top surface and coupled to an aft shuttle drive belt that is adapted to apply an aft-ward force to the aft wedge;a forward wedge positioned between the forward bushing slide plate and the top surface and coupled to a forward shuttle drive belt that is adapted to apply forward force to the at least one forward wedge;an aft spring and damper assembly adapted to apply a forward threshold force to the aft wedge; anda forward spring and damper assembly adapted to apply an aft-ward threshold force to the forward wedge. 15. The slide bushing supported cargo shuttle of claim 14, wherein the top surface is adapted to be displaced upward in response to the aft shuttle drive belt applying more aft-ward force than the forward threshold force and the forward shuttle drive belt applying more forward force than the aft-ward threshold force.
