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...

The front link translates when the TV is turned. As long as the TT/TV combination is generally straight AND THE TT WHEELS ARE ON THE GROUND, no realistic side force imparted to the TT can be great enough to translate the rear link of the HA.
Ed, if the TT tires are rolling, then the necessary side force on the TT might be much less than you think. Following is a response I posted earlier:
"There is a difference between tire static friction (when the tire is not rolling) and the lateral force generated by a tire when it is rolling. A rolling tire does not generate lateral force unless is has some degree of "slip angle" relative to the direction of travel. This is why a moving TT swings when subjected to a lateral force. The TT must develop enough yaw angle to generate sufficient side force to counteract the imposed lateral load. The side force is proportional to the tire's cornering stiffness, the load on the tire, and the amount of yaw."
