It sounds like you're trying to power a wheel and a live axle independently from the same gear, which is driven via its gear train. If that's correct, then what's the problem with just driving the axle and using the axle to drive the wheel? A relatively simple key or hex setup will work quite well to do this; you might even be able to do it with a single keyway/key on the axle.

Sorry, I should have spent more time to explain this...
The reason the wheel and axle are simultaneously driven is that the axle also transmits torque to a second wheel opposite the bevel gear set. To avoid the problem of creating a torque nightmare when both wheels pivot (think duelly's on a coaxial swerve), I minimized the distance between the two wheels to less than 1/2". Doing this required mounting the wheel directly on the bevel's hub and building the driven bevel into the wheel itself. Thus the need for pinning...
