I found a diagram of a Ferdinand suspension bogie here: http://www.tiger-tank.com/secure/history2.htm
The diagram shows a torsion bar internal in the bogie assembly running the length of the bogie. The front axle was solidly mounted to the bogie. The aft axle was attached to the torsion bar by a linkage that is not well documented in the diagram. So the action is the bogie pivots on the hull and the springing action is provided by the aft axle which moves in relation to the bogie arm. I can see why this design was not widely used. It's very highly stressed and doesn't provide much suspension travel. It does have the benefit of taking up no internal hull volume. The closest design to this built by our members would be the pivoting unsprung bogie system used by Marc on his big Leopard. http://members.upc.nl/m.methorst9/7.JPG http://members.upc.nl/m.methorst9/8.JPG http://members.upc.nl/m.methorst9/9.JPG Steve Tyng On Mar 9, 5:40 am, Pete Arundel <[email protected]> wrote: > I'm not planning on building a Ferdinand / Elefant or a Porsche Tiger > but does anyone understand how it's suspension works?
