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...

Gee, what a breeze. :B
Hensley says:
The secret of the Hensley Arrow rests in its patented converging linkage design. The Arrow allows movement on the ball in every direction except side-to-side. Side-to-side movement is forced to go through the linkage system which is one directional. From the trailer side, the linkage is solid. Pivoting by the linkage must be initiated through the tow vehicle. The system's design is inherently stable. Best of all, it functions mechanically, without the use of friction so it exhibits consistent and predictable behavior regardless of changes in weather or road conditions.
This is exactly what Hensley said. From the trailer side, the linkage is solid. The Arrow allows movement on the ball in every direction except side-to-side. (It is actually locked up from the trailer end).
Once again, making assertions is not good enough from the perspective of the liberal scientific method, and I see a lot of assertions, but no alternatives, and no means of testing the assertions.
And once again, Ron trots out his red herring, stating that I was fortuitous in finding exactly the right angle. There is only one place the cable can be attached that duplicates the strut attachment. Once again, he fails to demonstrate how these forces might come about, or how they may be applied to the hitch except at the mechanical points of connection, which is where the cable is attached.
Tluxon trots out his red herring, how can a pull on one end of an iron bar be the same as a push on the other end of the iron bar. I don't know guy, but with a few decades and a calculator, somebody might figure it out.
JD Whittaker has still not figured out the meaning of a unidirectional device, and needs to go look at the video again, at the part where the trailer is shoved over and the hitch does not bend. JD, what you are referring to is the tow vehicle initiating a turn, and it can, because the hitch is not locked up from that end. As Hensley says, "Pivoting by the linkage must be initiated through the tow vehicle." (It is actually locked up from the trailer end).
I have the Hensley statement, the theory of 4 bar linkages, specifically as it relates to toggle point, and a picture of a 4000 pound come along demonstrating a locked up Hensley Arrow hitch in an easily and endlessly repeatable experiment.
Now show me yours. :B
Burbman, thanks for the film. I wish I had thought of that. :B
On edit, I forgot one of the assertions that needs to be dealt with. Hensley says the following under "Safety,"
The Arrow mechanically locks sway out and creates an inherently stable relationship between your trailer and tow vehicle.
I know how it does that. :p
