    I hear ya on the rocks ,dirt i dont think would be a problem ,those belts are pretty tough,and theres a lot of different grades and brands.

    Basically just replacing a differential and axle with a light weight tubular housing and a pulley.the rest is basic truck 3-link.

    What about the side loading/wear on the belt when it twists? Am I wrong in thinking you are talking about a cogged belt? If it is a cog belt I really have concerns in it ability to allow twist without wearing out the cogs.I'm intrigued but still have my doubts.

    Heres a pic of a 3 or 4 link whatever.

    Pretty simple.

    Now just replace the axle/diff with my pulley/tube setup.

    All comes down to the belt ?

    "I'm intrigued but still have my doubts." *Me too.

    Yes, cog belt ,stock 7/8 harley drive pulley and *belt.

    I'm trying to think,once the belt is on the pulley is there really any more side load on it than normal?

    I'm thinking of a guide/tensioner that will align the belt on the bottom of the pulley.

    Good luck with it...
    I won't say you can't make it work...but the money and effort you will be putting into a system that has been tried and never worked on a non drive shaft set up. could be better used somewhere else...I know this cuz I know a guy who designed the same thing about 6 years ago...and I think that set up has been recycled into a chinese POS. for at least 5 years...
    I think it's cool that you are thinking out side of the box...

    I say go for it. Take a look at the Trophy Karts, they run solid axels, but it moves like a 3/4 link on a truck. They run a chain too, not a belt.

    I am going to go for it.

    Do they really work like a 3/4 link or just a swing axle?I dont think they articulate much.

    bullnerd, I think that when your setup articulates the belt will have to grow, won't it?

    Just for grins and giggles ,how about making the pulley remain perpendicular to the horizon on some sort of narrow swingarm and putting a cv in the center of the driven pully to allow articulation while at the same time keeping the belt properly aligned with no twist? In other words the cv outer race is the driving element connected to the pulley while the cv star has the axle running through it as the driven element.Did that make any sense????? [smilie=banghead.gif] I know you can make something like that work and get about 25degrees *+- articulation.
