Ideas on designing a CV axle for 4wd

Xtreme Cartz

I've got an electric rear end that I would like to install on the front of my gas EZGO for on demand electric 4wd assist. It wouldn't be a problem to fit the 6 batteries under the seat, I can get 2 on the side trays, 2 on the cross member in front of the engine(I think), and 2 in the bagwell.

Anybody got a CAD drawing my machinist could use for making the cv axles and spindles?

6 batteries and an electric rear end will add about 5-600 pounds to the vehicle.... Are you sure your gas engine will handle this?

Xtreme Cartz

Yeah if its just a 2 passenger there shouldn't be a problem and all the extra lbs helps traction. It would be close to the same weight as passengers on a cart with a rear seat.

I like the idea of the bad boy buggie, but its electric only range won't cut it off road. I need a cart to ride around the house/neighborhood on electric 2wd mode, gas for long distant driving purposes, and 4wd for when I get wild off road. Plus if something were to break out in the woods, I gots a back up system to get me home!

I think this would be a cool project. Post lots of pics if you decide to build it.

If you hadn't said "around the house/neighborhood in 2wd electric mode", and were ONLY going to use the electric for the 4wd assist, I'd say don't bother putting in 6 - 6 or 8v batts, just go with a few 12v's, since it wouldn't be getting used that much. Should save quite a bit of weight doing that.

I wish I had what you're looking for, because I too have thought of doing basically the same thing. If you do make it happen, please post lots of pics, and sources for parts, so I know what to do if/when the time comes. :)

I so badly want to get my hands on a Jaguar independent rear differential and full suspension, and mate it to the rear of a cart, so I have a fully independent suspension cart.

cheaper would be suburu wagon or car. should be able to get a complete car for less than $500. just resue the front struts with drive axles and rack

SP-Electronics

Yeah, that's true. About a week ago there was a subaru 4wd wagon on craigs for $350, and I was very tempted. It was pretty rough, but probably wouldn't have been great for parts.

Maybe Xtreme should do that. Just get the front driveline/suspension out of a 4wd or fwd car, and mate it to the cart, and mate the electric motor to it. He's got plenty of experience with electric car conversion, and mating electric motors to other transmissions...

Club Car makes an electric 4WD golf cart. It has an extra motor mounted up front and CV shafts and joints on it. Would be too costly to just go buy one of those setups but maybe a local insurance company has one that they had to buy due to damage or theif or what ever. There are several "lots" around the country that deals in insurance sells of vechiles from snow buggies to motorcycles to golf carts. Try one of those, you may find something there fairly cheap to use.

You might have better luck with an ATV front end and adapting the motor to the diff.
The Yamazuki has a locking diff up front so it free wheels in 2WD or push a lever to go 4WD.

SP-Electronics

That's actually the best idea crash12888. Finding a used 4x4 quad to rob the front driveline out of might be the hard part though, without buying the whole quad. I have found loads of regular 2wd quads cheap ($100-500 complete), but the 4x4's, especially ones with locking front diffs instead of full time 4wd, are still pricey.

Xtreme Cartz, did you find anything yet?
