This is what I know:
The inner CV's outer shell 'stands still' relative to the engine and gearbox, rotation excepted.
So if you can find space to mount said hub motors to that/them and a sprocket on the CV's outer shell; you're good from an engineering standpoint.
The chain or belt tension will put an extra load on the bearing the CV/s fit into, but I'd be willing to bet they can handle it.

As said: Just an idea based on my research and thinking on the:
"How to easily electric assist a car".
If anyone has a better suggestion; I'm all ears!

Er...
Perhaps you're trying to picture a single chain (driven by one motor) around both inner CVs?
I'm seeing one motor and chain per CV/side.

I'd take a look at the internally-mounted front brakes of some ancient CitroŽns such as the 2CV for packaging references.

Sorry that was me being lazy. Allow me to try:


http://www.alfabb.com/attachments/al...nd-jpg.131000/

Any transaxle with inboard disk brakes. You could mill non-ventilated rotors into sprockets.

edit: As soon as I posted I see cRiPpLe_rOoStEr covered it. I picked the Alfa for it's DeDion axle.

2nd edit:
I also picked that picture for a particular implementaion of the Watt's four-bar linkage, the Panhard rod.

i didn't realize that was a "thing" seems like it'd be a pain to do the brakes, but, i wonder what advantages it might offer?

Less unsprung weight.

Not sure exactly why the Humvee resorted to internal brakes, but most likely unsprung weight was not the reason. Most likely another advantage was the brake rotors being at a safer location regarding road debris, also accounting the increased riding height provided by the portal axles.

See the 6 bolts holding the inner CV on:
Thats where I'd bolt a sprocket with an appropriately sized hole in the middle and with the correct tooth ratio to get the desired (top) speed you want from the elec assist.

The hub motors: Wherever there's space.
From what I recall of rear boxed Alfas; Probably mod th chassis to ,make room under the back seat for them..?
Mounted to the gearbox naturally.
