Further to my previous post in which I promised pics of an entirely wombled design involving recycled escort/orion/fiesta rear hubs.
You will hopefully see from the pics that it is extremely simple, involves no springing medium at all and allows a tilting trailer with a very very
low bed height and no need for ramps.
Comments, Questions ?

P.S. Not my 'facility' - all the locals will work it out easily though

Know as a walking beam axle, had them on ag and industrial trailers for years. The major down side is that with no spring they bounce like hell a high
speed, 40 km/h behind a tractor with one seems to quick.
It can be improved by adding suspension to the draw bar, but still not a nice ride.
You could add suspension to the central pivot meaning you can still get away with not needing rams.

If you have ZERO suspension springing, (i.e. compliance), you may have to severely restrict your towing speed. Unsprung trailers can become
uncontrollable at high speeds.
Don't forget tyre springing changes dramatically, from static condition, to dynamic, rolling condition.
Fair enough chaps. I'll only comment on this trailer as it is my only experience of the concept. It does seem very stable and does seem to be
very much under control.
As an asides, I honestly see this as being quite different to one where the hubs are simply bolted to the chassis with no movement permitted at all.
Surely that is an honest definition of no compliance. This setup does have compliance in practical terms.
I'm listening and more than willing to learn though.
P.S. the builder is a retired trucker and freely admits to having used the idea from HGV practice of many years ago.
wy not make an suspension trailer just wider??
then you can put the car between the otherwheels?
whats the max vehicle with?
maybe with small tyres?
Tks

i thought it was 8 feet max...
I may be totally wrong, but I thought that all trailers for road use have to have suspension.
