Thanks guys! :yes:

Hi, pardon my ignorance but what is there a benefit for a belt driven off roader, or is this just one of those projects where the main reason behind it is "because I can" (something I have done plenty of times :)). Just curious is all.

Well done, your workmanship is top shelf.

I Love your projects MMan. I thought the CORR truck was amazing but I didn't expect to see yet another sweet project none the less an extremely ingenuitive one. This is what the true meaning of this hobby is. This is like seeing the first electric conversions, it just awed me.... I can't wait to see how this turns out. I only wish I could make things as awe inspiring as you can make em.

After that rant I must point out my user name has nothing to do with you, thankfully. :eyes: I am referring to the music genre of metal, and that I like to listen to it. :smile: I made it up long before I joined this site... :wink:

I'm curious to see how the belt holds up. I would hope there would be no diff problems. I would expect this to be a more efficient drivetrain also.

Dunno about benefits at this point, but I do know that this truck won't experience any torque twist like ALL shaft driven vehicles do. Also, if the belt layout were optimized it would be possible to place the motor and battery directly on the centerline of the chassis which would improve handling considerably. My current layout isn't the best, unfortunately.

The main point behind this project is because I can, and because it's never been done before. Most of my projects are unique :neutral:

My username also has to do with the music I listen to, but we probably listen to different genres of metal. I also got my big start in RC by working with aluminum so that helped too.

Thanks for the comments guys!

hey i think it time for an update!

It is... still waiting for another front belt to come in, and for my homework load to lessen. And I've been working on the final project for my Solidworks class:

A digital representation of the belt drive Mammoth ST Pro! Figured I would start with the center motor unit. Just a quick note: the motor actually rotates JUST like in real life, as do the pulley and gear on its shaft. The other shaft and its gear and pulley also rotate. However, I don't know how to link up the rotation of the two gears (so that the motor spinning causes the other shaft to spin). Anyone know how to do that?

Nice work, u did all the machining urself? what tool do u use if so?

great CG, Looks strong.

I'm not familiar with Solidworks. How did you go about "syncing" the other components? On that interface, can you select the direction of rotation and add a ratio between the first and second axles, then sync the second gear/pulley set to that second axle?

Looks good.

Have you checked out the mechanical mates in solidworks? There is an easy option for gearing. You should be able to work it out.

Did all the work myself, with a scroll saw for cutting, drill press for drilling, also chucked an end mill into the drill press for light milling.

Thanks :yipi:

The other components are "locked" together as mates, not synced together.
Sounds like I need to look into mechanical mates and add a ratio.

Thanks guys!

That's is pretty much it. You might need to add a circle sketch to your gears for the pitch diameters which you can then easily mate together using the gearing option under mechanical mates. Just line them up, and mate, and all should be sweet. Then you are a step away from connecting the front, center and rear pulleys together with belts.

Solidworks is fun. :)

So is Inventor..... :whistle: :mdr:

Okay, thanks for the tips guys! Drew a circle (sketch) on each the original gear files (diameter equal to the pitch diameter), and hid the circle sketches. Mechanical mates worked perfectly! This is very exciting :yes:

Awesome. Got any video yet? :lol:
