Again it's description but I'd say T-34 had compartmented springs, there's no access from inside the veh to the springs as far as I can see, have to look at the service manual a bit more. Length I'd...

Tension springs wouldn't work well in a vehicle suspension, because you have to include the space for the spring's extension somewhere in the design. You could pull on such a spring with a bell crank...

For interest do you know of any veh that have used Belleville washers? Ju-88s did but I can't recall land veh use.

Rubber cone suspension such as found on the original Mini/Mini Mokes in the sixties could be called a variation on the theme. Considered for military use.

Rubber was used as a spring on the LVTs, arranged in a torsion tube - like a bar but with rubber between two concentric tubes doing the springing.

Aha, now you mention it yes, one or more of the Es. Didn't know about Pz61.

Belleville springs can be wondrously non-linear, but need to be stacked to get enough deflection for a useful suspension. As for (coil) springs working in tension vs compression, I think one problem...

That wouldn't be the problem exactly, designing to prevent it would. Assume you do that purely by the spring having excess travel and you never hit bump stops nor bottom out the spring - that means a...

What he is referring to is the spring being pulled (in tension) can be pulled far enough to permanently stretch the spring, which would mean that wheel would no longer sit properly, and the hull would...

Even compression springs and torsion bars had bump stops. So the overextension of a tension spring would not likely be a real operational issue. Compression springs just made more sense, for whatever...

Compression springs would over compress under too much hard usage. I've just finished reading a book on WWI where there is a description of gunners with the recoil springs out of their 18pdrs,...

Almost any metal spring will do that. One of the theoretical advantages of gas springing.

AIUI not a huge problem with Chally; what has been is that if you don't drive them for a while the units take on a set and the tank settles at an odd angle. At least one Cav regt returned from a...
