My smoothest 3+R gearbox ever !

[piterx]

Hello everyone!

It's been a while since last time i posted somethinng!

You know I was trying to make the fiat panda dakar for the TC6.... i had some problems with that as i didn't like how the gearbox was working..

So i started from scratch and now i can easily say that i've built my best and smoothest gearbox so far :)

connectors of the black gearbox in the pic below couldn't give it the strenght it needed to run smoothly... so i rebuilt the grey one using only beams and it works great now as everything's perfectly straight and there are even less pieces so it's probably lighter as well....

i apologize for big pictures but i made em like this so if you want you can rebuild it from pics and test it :)

I'll build something around it even if i don't know yet what xD

hope you'll like it!

[Epic Technic]

Seems really strong and I'll probably use it. I was wondering where or how do we change gears?

[PKW]

for sure this is a great idea! What about finishing your panda?

[jorgeopesi]

I like gearboxes sure I will build it to learn how it works .

Can you share the LXF? Thank you!

[piterx]

this isthe way it's operated....

[PROlego]

Hello. I haven't got any driving rings so I wonder if you could fit the new version of the driving rings only removing the extender and moving the changeover catch half a stud to the side?

[piterx]

i think it's possible but not that sure because where's the extension there's the R gear

Is there any way of compacting this, however? At this size, Sariel's 4 Speed With 2 Servos seems better.

[piterx]

no way of making it more compact than that....

everything depends on what you wanna do with it... this one is meant for performances, it requires one servo only and it's meant to work with an autoclutch that guarantees good shifting while moving :)

gears have a good progressive ratio wich worked well with pajero, for this one is gonna work even better as it's synchronized

[VKTechnic]

Hmm, might have to build this someday... In the meantime, I'll wait for your next model to see how this performs!

How does it work with only 1 servo, and what is the auto clutch? I'm intrigued...

[Graydingo]

Posting in a thread. Been looking for a solid 3 plus R! Thanks Piterx

[Kelkschiz]

Looks solid and pretty. I'd love to see a video of it in operation.

I tried to build an LXF but can't complete it as I need more views/photos of the 'inner' gears.

[piterx]

im building a single block with 2 xl motors, clutch, gearbox, servo for operating it and brakes on the driveshaft

btw it's gonna work the same way as the pajero one so a rotation of 90 degrees is gonna activate the gears wich are placed like 1 - 3 on same shaft and 2 - R on the other

a single servo will be enough :)

Thank you. I'll upload the LXF as soon as done.

This sounds really cool! Can't wait.

As promised, here is the LXF, thanks to piterx. I added few parts to hold the gear shifters.

The new gearbox looks good.

Everyone is posting gearboxes, but what I would like to see is gear switching mechanisms with servo.

I use one in my latest MOC, but it tends to jam in between gears when switching gears one way. So you can say that it works only one way

Also it needs a lot of space. If anyone have some comapact ones, please share!

[EDIT] Ah, one more question. Did the gear ratios change?

there is one gear missing - small black - working together with internal Z24, but any way - thx, I will try to build it, maybe think on something for my current project... (supercar really needs a gearbox? )

That is really freaking sweet man! I shall have to give it a shot sometime soon.
