Flipping the axle voids warranty on a Winnebago 1706FB ??

these axles don't seem like the ones in the picture above
see attached
each axle is a bit offset from the center of the wheel, then there is an attachment at a right angle, at the end of the axle, which then is attached to a very short piece at the center of the wheel
not sure what you call this
I think I heard someone mention a torsion axle?

been trying to attach an image but don't see how, and clues?
thx
