Good for technic gearboxes!
As for your refreshment, sir, we strongly recommend our 2008 Differentiale, which pairs perfectly with fish or chicken.
Ah yes
D I F F E R E N T I A L E .
New for 2008, the Differentiale 3M Z28, available in 24 great smelling colors, with optional convertible top and "sun and sound" package.

Sorry, supplies are low, due to a chip shortage. (goes to the store to buy more)
An actual Danish part name. Interesting.
Seriously though, what does this part do?
I’m actually indifferent to this part.
I am gearing up to purchase this part.
I prefer the Integrale 3/2M^2 ZM 28M + C. Differentiales downshift too much for my liking.
Oh yeah Differentiale 3M Z 28. I remember when they won the Champions League
Now this is a rare, one of 308,848, Differentiale 3M Z28s in the color dark bluish grey.
Quite a name, but it's to expected from a technical element
So does a smaller cog go in the middle?

Usually three.

It allows axles to spin at different rates when powered by a common source, and is typically used to transfer power to the nonsteering axles on a car or truck.
When I hear about this part I am all gears.
Plus I just noticed that I own 9 out of the 44 sets this part comes in.
My sort of piece, something to get my teeth into....
With my interest in Technic sets and Big rigs, it is used regularly.
Apparently I've got 32 across 21 sets!
It's not much use with out it's additional 3 pieces that are needed.
CONICAL WHEEL Z12
These are normally found in brick yellow though can be found in otcolours. They allow the transfer of energy/momentum to the axles.
It replaced DIFFERENTIALE GEAR CASING
And I think it has subsequently been 'superseded' by a newer alternative part DIFFERENTIALE 3M, NO. 1 though it might be it is actual an alternative not a replacement to that part.
Sorry can't get hyperlinks to work for Parts!

Now that's a good question here, for anyone wondering.
A differential is typically used on a car axle that transmits the power/torque/rotation from the engine to the large gear. The smaller gears in the middle enable one wheel (the outer wheel in case of cornering) to rotate faster than the inner wheel. Therefor, it reduces wringing/friction, making it much easier to make turns and reduce wear on the tyres.
In some cases, differential may be (fully or partially) locked, which may come in handy off road, when drifting, or when there is a need to improve straight line stability at high speed, which I believe was first employed Ferrari 430 from 2004, please correct me if I'm wrong.
In four wheel drive vehicles, there will be a differential in between the front and rear axle as well.
Lego should make a Torsen differential by the way, for increasing the torque transmitted to the wheel that spins faster.
Other uses of a differential are possible in mechanical setups, using some creativity.

Wait, no lore behind this piece?
Wonder when we get a Technic piece that isn't in one of the Supercar sets (Lambo, Chiron, Porsche). I imagine it'll be a wheel, but is that designated a Technic piece?
No-one will answer this as I'm very late to the party today.
