Think an elegant and out of the box architecture, but the devil is always in the details...
The coupler latch/pawl is there for the worst case when Mr Murphy crosses your path
To keep the ball from coming out. Never was it designed for this kind of loading
except for braking where the TV has more than the trailer provides
A can do for now, but longevity is the main issue for me.
How long will that latch assembly last over time? What kinds of forces will it
see in 'normal' situation and in emergency and/or shock loading situations?
Another mentioned but not discussed yet. Is the chain/plate pin. Double shear
and assume the ball shank hardened along with the tube welded to the chain/plate
That is what rotates the whole thing against the friction material.
Again, how long will it last? Is the contact PSI distributed to lower that PSI
enough to not deform or work the metal over time?
A new thought that Ron might have a better understanding and explanation: When
the trailer tries to sway and the friction material resists...there is going to
be a push on the TV's rear end. What will that do to the suspension/tires/etc
Or does the whole TV see it and dependent on the tolerances in the food chain
from the ball to shank to receiver to frame...then down to the suspension
Where would the pivot then be? The CG of the TV?
