3 wheel drive?

[TrailerRider]

Been done before on ATC?
Here is a mock up (mspaint). It is possible I think. Hardest would be getting sprocket for wheel. Keep in mind the motor is not straight (mspaint) but with the chain/sprocket/motor lined up it could pull pretty good. Maybe a 6 hp briggs. I know our little kart with a 6hp briggs hauls with me (230lb) with a kid next to me. With the motor being mounted on the front rack you get extra weight and being as it is mounted on the front rack you would have normal steering still. Just have another drive wheel. Maybe for that hunter trying to pull that dear in to camp..

I go through some pretty good mud holes and once in awhile I get stuck with the front wheel on dry land and the back sitting spinning. Imagein getting stuck and reaching up and starting the little 6hp briggs (without standing in the mud) and throtteling the 3 together. Or the Snow for you cold weather wheelers If your motor crapped out and would not start you could run in 1 wheel drive (slowly) back to camp Then have a and say man that was a close call. Heck if you lost spark on the atc you could fireup the briggs/tech and give the atc back spark to get ya home if you did not want to run the little motor by it self.

Needed:

1. Briggs/Tech 6 HP motor
2. Wheel drive sprocket
3. Centrifigual clutch
4. Chain
5. Front rack with solid mounting points for motor.
6. Remote throttle from Briggs/Tech motor for revving both same time..
7. Build update: Added front braces to stop shock from working temporarly.

If there is not to many na-sayers then I might give this a shot.


Yellow lines is Chain
Red is throttle cable/likage
"Black" is gas line (If your briggs/tech ain't got a tank you share off atc)
Purpule is support braces to keep shocks temporarly locked from absorbing shock.

i doubt there would be enought weight for the front wheel to get any traction. And if the front forks had suspension everytime you hit a bump the front chain or belt would fall off.

[TrailerRider]

Hmm, intresting. I did not consider the shock as they were pretty well mud covered. lol. Ok So add 2 small braces that connect from rack to wheel. That will resolve the poping chain. Don't think a 30lb motor sitting directly on front froks will apply enough pressure to atleast help the process along? Maybe you could lean forward and give more weight. Plus "if" you have gas in the little motor gas tank thats atleast a few more pounds.

that would be cool if someone could make this happen. i bet it would do awesome in the mud! but yea the shocks would be a problem. you could swap out the front for one that doesn't have shocks.

I've seen three wheel drive bunker rakes before for golf courses. We don't have any at the course I work at but they are made by Toro and called Sand Pros and they are hydraulic drive. Not sure if there is one motor or two for the rear but there is a motor for the front wheel as seen here:





Not me in the pics btw, just some google pictures. We have these at our course, but not 3WD



With this idea you'll need a hydraulic pump and reservoir, and know how to build the rest of the hydraulic sytem to work properly

KTM has a prototype 2 wheel drive dirtbike, you could do something like this:

well guys I have the most logical answer to all of your questions and or ideas, I had the master plan for this but lost interest in the idea, I have a rokon 2 wheel drive off-road motercycle, it spins with the front wheel and the rear wheel, I put a honda 90 3-wheeler engine in the frame with high and low range and is now a 4 speed, Now this was my plan- take off the rear wheel and transplant a kawasaki differential type rear axle in its place, boom boom done, now you have a reliable, not cobbled up 3wheeldrive machine with a differential, now if anyone may be interesed I want to sell my rokon 2 wheel drive bike, it runs and drives with a honda 90 engine, goes just great shaifts through all the gear s and goes into high and low just fine.

I think the 6 horse is way overkill... the added weight will be very detrimental to handling, and the front wheel drive would really only benifit at very slow speeds or in mud... I would use a much smaller engine... a small 2-cycle engine geared super low would be my choice... or even electric drive system with a directional clutch... because for 99% of situations the added weight is just going to be a burden

2 wheel drive bikes have been around awhile. check out the Christini 2wd bike system.

you could just weld the forktubes, they don't do to much anyways.

[01ps]

If you were interested in only low speed traction, like for mud or an assist for climbing, would an electric winch motor work, if geared properly? And the front wheel hub is so deep I wonder if the motor could be mounted inside the bell of the wheel?

3wd would be cool though, especially those times you need just a little more traction...

[NewfieBish]

hey man.. what if you ditched the whole second motor idea, and welded another sprocket onto the one already on the motor. then run a couple of chains, so you could have it comin from the original motor. you could even solve the problem of the chain popping off the front that way. run the chain from the original location of the sprocket, then down to a solid sprocket welded onto the frame, then weld another sprocket onto that, and run that one to the front, so when the forks compress, just like the rear suspension it will simply pivot.. want me to draw a paint? haha

[300rman]

want me to draw a paint?

YES. i failing to understand how this will work when you turn the wheel lol

[NewfieBish]

YES. i failing to understand how this will work when you turn the wheel lol

you know what, i didnt even think about that... ANYWAYS lets forget andrew just said that idea there hey boys! the only way this is gonna work is if you wanna use the 2 back tires and thats all. unless you wanna do some crazy universal joint or some shiznit

[MyMistress86R]

I don't see how any multiple motor solution could work here because you could never get the gearing to be exactly the same and it would be more than difficult to get them both to rev at the same rate. The only way it would be useful is if you only ever rode in crap that didn't get the same amount of traction all around, i.e. snow, ice, wet mud etc.
