I see clutch plates…limited slip differential?
Looks like it to me. Very nicely manufactured!
Looks great. good job guys. Just one question why did you use helical gears?

Nice work! I was really hoping some team with amazing machining capabilities would make an awesome ackermann set up, and you guys pulled it off very well.
Yep. The clutch torque is adjustable. Just dial in the torque you want and off you go. It’s very nice. (Available from Mcmaster-Carr)
The truth is they were lying around the shop from a past prototype and since it’s still a COTS part, we used them. These are actually “Spiral Bevel Gears” from Boston Gear. I was inspired by the Lego Differential in case your thinking there’s something about this design that looks familiar. 
Very nice! Whats the part number for those spiral gears. Those look perfect for a differential project im working on.
This design uses:
(2) LSA110Y-R (Right Hand Spiral)
(2) LSA110Y-L (Left Hand Spiral)
Both are 18 tooth, 18 DP spiral bevel gears.
Mr.Sparks as a fan of drive systems, I am quite impressed with what you have done here looks great. Will 34 be attending the Palmetto if so I will take a look at it there if not Championships for sure. Good luck this year.

should’ve taken it one step further with 4wd, then maybe 1 step past that with 4wd 4wheel steering:D
i wonder if anyone this year is upscaling and high performance rc car 4wd and full independent suspension, that would be awesome to watch drive.
i love the limited slip differential
Unfortunately, we will not be at Palmetto this year. We are attending Peachtree and Bayou.
How difficult would it have been to integrate the clutch plates into the diff housing, like in a normal automotive limited slip rearend? Seems like a lot of extra hardware there…
(when we were considering Ackermann steering, we were planning on using a software differential)
I’ll probably work on this during the off season. This was a simple way to go given the time constraint and limited resources.
