Fioroni Tractive IV diffs exposed

[Sammus]

pimp: that is how the ofna torsen diffs are designed, they have an exploded pic in a manual on their website (im pretty sure it's what your talking about)

brushless boy: the fioroni diff is a kind of torsen diff just not the worm gear type that ofna call torsen, and theyre nothing like the diffs in the new xray xb808 at least (well, according to the exploded view in the manual which shows a standard oil diff, i dont own one to pull apart here though)

Heres a pic I found, looks alot like the true trac. Interesting, I may have to try one of these...

Linc, what are you planning on putting this in first? I would like to see it fit into Mike's hybrid diff case for the revo. It should work seeing as the description says they fit the hot bodies lightning as well as the ofna buggies. The price I see on tower for what you get doesn't look too bad, only 120 per diff.

I would like some more info on the diff. I am guessing that off power it will work as a conventional diff, but on power will effectively lock the outputs.

Looking at the gear design it is basically like a worm gear setup where rotation can only be applied to the worm gear and not the other gear, as the force will be applied in the wrong direction. This allows the output shafts to rotate freely off power when turning, but will lock when power is applied to the diff assy. I was going to use it as a center diff, as I generally like the feel of a locked center drive but find the decreased turning circle of a center diff equiped vehicle desireable as well.

Plus I like cool do-dads, and am planning on buying a true trac for my big block f250 (1:1 project) and do not want to go with a rachet style locking diff (detroit locker for example).

This is a pic of the Xray active diff.Its the very simular to the Fioroni Tractive IV.
