Ultra-compact Christie Suspension

Just an idea I've had for one of my projects but eventually decided not to use it because it looked wrong for this particular project. It works fine, though, so I'm sharing. It's pretty simple and may be obvious, but perhaps it will help someone.

'Simple, obvious' solutions are often the hardest to come by, so thanks for sharing!

With the new 2x3 l-beam (in the top of the boom of the new excavator set) this will be even easier to accomplish, and stronger too.

This setup should also work for (the rear axle of) small/medium sized buggy like vehicles with regular wheels, route the drive axle upwards along that beam and connect through a 90° mesh over there and it can be RC as well...

The non-driven version looks simple but effective :)

Have you tested the driven version? I would expect a lot of friction because the driving axle is also the load-bearing axle. I'd suggest replacing the first (= on the fixed axle) 16t gear with a red round-holed one and then adding an extra gear on a separate axle that drives that.

Yes Eric, good points. Alternatively, I would consider adding extra support for the pivot on the outer side, to make it more rigid. With a 5 studs wide track, there should be enough room for some supporting structure that could be later covered by the side skirt. I won't be working on this design anytime soon because I'm building this instead:
