Rear axle drive.
« on: 18 Aug 22, 09:28 pm »
Normal setup for a solid axle is to have one hub keyed to the axle and the other free wheeling.
Has anyone ever tried using sprag clutch bearing in the free wheeling hub ? Would it work ?

Wouldnt that act like a solid rear axle, when you turn 1 direction, but only 1-wheel drive when you turn the other? Plus it would only give you 1-wheel braking too?
I'd be interested to hear if anyone has done this too, as that sounds kinda sketchy to me. I guess it could be handy for when the driven wheel loses traction while on the power.

Thinking about it, I think you are correct.  You would need one way bearings in both hubs but that would put them under a lot of pressure, not sure how strong they would be. You would also need disc brakes on each hub rather than the axle.

Some people go with a GoKart differential, however much light, simpler, and cheaper is
Solid axle, with one wheel keyed and the other free to rotate...but what I did to give a
partial diff effect was put a split collar jammed against the wheel hub. Spins with the
axle but can rotate at a different rate to the fixed wheel.
The difference is very noticeable in the levels of tire ware.
Also yes I only have technically one wheel breaking...don't worry about it, it's fine.

This video might be of interest Noel, I don't know how it worked out for him - but interesting...
