Hensley Arrow: How does it REALLY work?
There have been several discussions on this hitch that have become somewhat 'controversial'. I am NOT trying to stir this controversy/bashing back up. Instead, I'd like to see a good, intelligent di...

Tim,
Excellent drawings(Figs. 1-3), they depict the only movement that the HA is capable of, well except for the opposite motion of course. It should also be noted that this type of motion can only be created by the TV, as in the case of a TV initiated turn...unless something is very wrong. Big hockey puck, or unsafe travel on very slick roadways or the like. It seems that alot of people posting in this discussion are interpeting other peoples posts as absolute statements...ie. can not happen, or can only happen this way, when in fact I think most people are trying to say something can't happen, or can only happen a certain way under normal circumstances. My interpetation to the forces and motion associated with sway are different to the forces and motion in the figures above. I see sway as a rotational moment with it's center at approximately the center of all of the axles on the TT, and it's affect on the TT and TV. The HA all but eliminates that type of motion except in the case of extreme conditions. I'll attempt to make and post a little sketch of the forces that I'm describing, as well as a short video of the HA moving while mounted only on the stinger(as Milt and I have done). I think the video will really clear up alot of misconceptions about the motion of the HA.
I am still looking for an explanation of the Virtual Pivot Point, and it's role in all of this, that I can follow. Anybody?
Tim, you must have 40 or more hours invested in this discussion, I don't know where you find the time. Thanks
