Ball Diff on this Car?!?

[dgilpin]

This is the side with the tension screw. The screw tightens against a ball bearing.

With the screw and one half removed, exposing the spur, balls, and one plate.

And with the spur removed showing both plates.

Thanks dgilpin!
Excellent pictures!

The one I've made soaks up more torque than I'd like and I'm trying to figure away to improve this. Does really improve cornering, but at the cost of serious acceleration. Your pictures have already suggested an improvement: locate 6 balls (instead of 3) farther out, .25" instead of the .17".

Still, I think I need more tension. Perhaps if I could get even the inner plate magnetic...
Thanks,

ncredible work, how do you make such tiny stuff? What tools do you use? I hope once you get a final prototype you sell those cause I would buy one!

I'm a shade confused, but I think I get the general idea.
Why not use a 3-gear differential? With 2 gears with horizontal teeth (facing each other) and a 3rd gear spinning freely between them, it would work great. You spin 3rd gear, which spins the other gears in turn. If one side slows down, the center gear adjusts the other one up. And you would get nearly no loss of torque with gears.
You can see what I mean with the LEGO diff-same idea.
Of course, you would have to be a clockmaker to get the gears to mesh....

your probably rite ... when you get this small a 3 gear diff would probably be better (like a Bit Char-G) but Yokomo made this car based on larger RC cars. thats probably why its a 2 gear diff
