That is correct...not slipping means constant velocity in this case...as if the tire pushing slipped, the velocity would decrease.

So V = Rw as I stated, under the conditions that we are both discussing...as if the tire slips....then its not rolling at a contant velocity, and its WHEN it slips that is of interest.



What is happening at the pictured "unloading point" that you don't like is unclear...it seems to be at the end of the droop, far after the regular shackle lost ground contact anyway...

....plus, the graph does not show any reduction in downforce on the regular shackle, as the leaf starts to hold it up, rather than push it down...as the progressive loss of leaf pressure happens rather soon in the droop cycle.



Of course...the angle would play some roll in the lever action...as the weight on the stuffed side spring is also pushing down the drooped tire as well.

As I am primarily comparing the Revolver to a regular lift shackle...and at the same points...the regular shackle is losing or is out of down force before the Revolver...but, is getting the same leverage that the revolver is getting as far as that stuffed leaf pack's push, etc...

...its just fighting that force, because the regular lift shackle's drooped leaf is pulling back up on the drooping tire on the way to its full droop.

I'd like to take a fork lift and a truck scale, and just plop the X on it one corner at a time...lift the front tires to droop the rears, and see what the real #'s are.

The other Myth we could then kill is the one about any old live axle, like the 2 the jeeps come with...having no down force on the drooped tire unless the coil spring is reaching all the way at full droop.

Its pretty much the same principle.
