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 TT end of the linkage (the rear, upper, orange part of the HA) can move side to side and also can rotate (yaw). In fact, it only can move if it simultaneously translates and rotates. This is exactly what a pendulum does. As any given point on the pendulum rod moves to the side, the rod simultaneously changes its angle relative to vertical. If a lateral force is applied to the TT, the TT will swing to the side until the yaw angle is sufficient for the tires to develop an equal opposing force via their slip angles."
The orange head on my Hensley is fixed into position and never, ever moves. Two great big iron bars keep it from moving at all. There is no movement except through the linkage.
Tim,
"The VPP moves only as a result of a change in geometry. The lateral forces may or may not result in a change in geometry. With the Hensley, the vast majority of lateral force is reacted to by the tires of both vehicles due to the nature of the leverage of the linkage."
My point exactly. The leverage of the linkage prevents a change in geometry.
