Torsion Bars on WD Sway hitches
Hey all, I read this article about torsion barsand am having a little trouble understanding it completely. This is the part I'm not understanding "Reese dual cam sway controls unequally increases th...

In a turn the cam rides up and down the crooks of the WD bar. The cam arms do not move and are in a fairly fixed point relative to the length of the chain. So when WD bars move in a turn or in a sway event the amount of pressure increases on the cam arm.
In theory this force should tend to make the hitch settle back into the at rest position at the top of the crook.
You can see the forces with a simple experiment. Take a rubber band and stretch it between two fingers, Now take your other hand and grab the middle of the bands that are stretched.
now, pull the rubber band from the middle. You will feel resistance from the band trying to overcome the pulling force from the middle of the band.
This is similar to the force that is at work in the DC. The cam arm is your fingers grabbing the rubber band in the middle... the rubber band is the WD bar under tension from simple WD. As the band (WD bar) moves it increases the force and the WD arm wants, tries to return to at center.
Hope this helps,
Thanks!
