New differentials, are they THAT good?

[Zerobricks]

I hope it's not too offtopic, but here's how you can use the new diff as a gearbox clutch gear component:

• Yellow axles are inputs, they can be on both sides of the gearbox
• The red axle is the output and it can only be on one side of the gearbox
• Same goes for the orange axle - the wave actuator

It has a massive gear ratio of 3,5 in low gear and 0,8 in high gear, giving the gearbox the total range of 4,375.

II think we can use this idea with a combination of the 24-16 differential and the usual clucth gears to make a linear gearbox with 4 gears with the following meshes and ratios:

• First gear: 8:28 - ratio of 3,5
• Second gear: 12:24 - ratio  2
• Third gear: 16:20 - ratio 1,25
• Fourth gear:  20:16 - ratio 0,8

How will the wave selector activate the gears in the right order?  Right now you have 1-N-4-N as the wave selector rotates.  You can't squeeze two gears from the 16/24 differential into one wave selector position.

Simple fix.

Rearange the gear pairs so they follow the right order.

And here it is, the 4 speed linear gearbox, with as few gears as possible:

Hmm, this is pretty cool and simple even with this trick using the differentials as clutch gears. Imagine how more compact it could be if those appropriate sized clutch gears existed! And TLG would say it does not exist because they never needed it. Not that the Defender gearbox could have been simplified with them..

BTW, I think a 16T gear is missing from the lower axle of the lower image, under the blue gear.

Indeed, pretty functional and relatively easy to place in models.

I also found a way to use this differential as a central differential Lo-Hi gearbox and diff lock, but maybe I should post that in a seperate topic?

I think it deserves a particular topic. 

Let's keep this one for the lights and shadows of the new (and old) diffs, isn't it?

Not much more one can say about it.

You mean like a 2-in-1 build? I'd definitely be interested in that!
