The idea is you get the pluses of the independent's low unsprung weight (good for ride and handling) and the live axle setup (wheels planted firmly to the road by maintaining camber independant of suspension travel). As a way of doing things it works pretty well but with some new compromises.
'Splain it to me some more...
I understand the camber advantages, but maybe I'm not clear on the way
the tube works. As far as I can see the tube is simply bolted to the
wheel hubs in a static manner. The two halves of the tube slide
laterally, but they do not rotate with respect to each other, and the
tube is stiff. Therefore, when one bounces or leaves the road, I would
think that the other wheel would have to be affected. In fact, I'm not
sure why something doesn't break. If the two wheel centers are on the
same plane and the camber is fixed, how can one wheel go over a bump
without changing the camber of the other wheel just as it would in a
live axle setup? Are you saying that the DeDion tube flexes? I can't see
where it is designed to do that.
I've read the theory, but how does it actually work?
