Strong, Robust Open Differential

[PorkyMonster]

While playing around with the small turntable, I realised it can also be used to make a strong open differential, as follows (the red part of the differential need not be present, depending on usage):

I'll be using this as the center differential for my "Yet Another Supercar (Gen II)" .

Another good place to use this is in mechanisms that uses those inner gears of a differential heavily - e.g. automatic transmissions that rely on a differential to detect overwhelming torque.

Wouldn't the four knob wheels cause a lot of unneeded friction? THree with a separator taking the place of the fourth would be plenty strong for almost all applications.

You're right. 3 of them would be strong enough. I lubricated them that's why I went for 4 .
