Nathanael Kuiper's Jeep Hurricane

[Blakbird]

Actually it does have a function, otherwise he wouldn't have it there. It is balancing out the torque being applied to the small bevel gears on each side.

Nope, the additional spider gear carries no load and has no function^*. In order to carry load, it needs to be anchored to the differential casing with a pin (like the other spider gear). It is not possible for it to react unequal output torques without this anchor. If you want to test it, try building a diff with ONLY the unpinned spider gear (leave the normal one out) and watch it pop right out of the assembly as soon as one of the axles turns.

^*OK, there's one function. It doesn't carry any load, but the combination of that extra gear and the two 1/2 bushes he put in there make the whole thing fit more tightly together which makes it harder for the bevel gears to slip. They can't slip if they can't expand.

I wonder if Nathanael Kuipers' JEEP HURRICANE could be made out of the 9398 4x4 Crawler's parts. They both have four-wheel drive (4WD) and four-wheel steering (4WS). NK's Jeep Hurricane model could not actually DRIVE ITSELF (due to the limitations of available Lego parts at the time), but maybe it could be retrofitted when the orange/black/white 9398 4x4 Crawler is released in August 2012 with the (likely) Power Functions "L" Motors...

I've built this model. The inability of the model to drive has nothing to do with a lack of power, so I don't think the use of a new motor would change anything. The drivetrain is very complicated with a lot of gear pairs, backlash, and compliance. That's the problem with driving. If you apply enough power (like enough to drive), you simply fail or slip something resulting in the wheels being out of sync or disconnected.

By the way, Nathanael has posted some new CAD images of the drivetrain which more clearly show the level of complexity. I did manage to figure out how it all worked before building it, but it took a lot of study to get there.

Yeah, I remember that, inspired me to make my own working version, could not be bothered with the bodywork tho

Since i started visiting this site only from july or something, i missed this model.

What an awesome machine. The looks with the unimog wheels is just fantastic.

I like the functions it has, and would probably be even more stunning when made radio controled.

Good job nathanael!

I´ve seen many really good MOC´s on Eurobricks, but this Jeep Hurricane is just awesome.

I would spend a fortune to get the chance to build it, the look and the functions are just amazing.

Will there be any instruction to rebuild it?

Instructions would be a VERY large project. There is a CAD file, but it doesn't have any kind of building steps in it so it is extremely difficult to build using that file. There are many times you need to remove something to install something else, but it can be done. I think in order to convince anyone to spend so much time doing instructions for this, there would need to be sizable interest.

Can anyone post guide or instructions how to build this masterpiece?

Any info could be useful - parts count, used sets and so on

Omikron, didn't you read one post before yours? There are no instructions and it looks like, there never will be.

That is true. I'll hope with you.
