In 1984 I did a BSc Thesis on the conceptual design of a light off-road utility vehicle. I investigated several possible propulsion systems.
I was at the time most interested in:
-diesel-electric,
-petrol-electric or a
-diesel-hydraulic drive train.
This was because these concepts gave me the most freedom in designing and laying out the utility vehicle.
But I could not find suitable electric hub motors or hydraulic hub motors as all the available products where far to heavy for a light utility vehicle like I had in mind.
The products I found where mainly for use in heavy earth moving or mining vehicles where weight, and bulk, was not an issue.
My concept vehicle was thus conceived with a mechanical drive train which was rather complex and expensive on to boot.
I need to scan in some drawing of my vehicle as in 1984 most designs where drawn by hand and information distributed in typewritten reports.
Stay tuned - and in the meantime enjoy the huge Rollington Vehicles.
