Low Speed Manuevering Prototype
We wanted to see if we could utilize the drive motors on the vehicle to create a feature that would allow a user to easily back their trailer up without a vehicle. To do so I conceptualized, designed, and built a steering system made out of 1/2” steel, a few custom components such as a custom bearing carrier, a custom machined steel caster wheel support, and a custom shaft cap that allowed us to use a convential 36mm socket and a long breaker bar to do the steering.
With testing we found that since the trailer is a dual axle, the trailer tires scrub quite a bit so the turning radius is limited.
Baby’s first steps..

CAD of the low speed manuevering system. It had to be really stiff so that it wouldn't deflect given the loads so I built it out of 1/2" steel.

Side view, everything in light gray is a custom part designed by me, as you can see the wheels have around 10 degrees of caster to allow them to self correct while steering.
