Super smooth switching off the differential. It's also a very small and efficient Lego Technic 2 speed automatic transmission. 1:1 and 1:3 gear ratios.
I called my dad, woke him up from watching tv and told him to watch your video. I had to pull the phone away from my ear because he was ecstatic when he saw it work. Congratulations, you got the dad seal of approval!
Wow that's actually really clever, love the way the 16 tooth gear slowly moves then snaps at a certain torque level. Most importantly it scales up to a usable model and still works. I'm a purest and don't like modifing parts apart from a very limited number of reasons, but this is one reason I would. Thanks for sharing this :D
If you build this you might need to make some small alterations. The correct spring might be hard to find, use rubber. I used a special slippy dark grey gear. There are plenty of ways to build this gear set up.
This gearbox is so awesome and made me so curious, that i instantly wanted to figure out how it works by replaying the first 15 seconds over ond over again until i got it. Then i realized, the video actually goes longer and includes a full detailed explanation LOL.
Ohhh snap! That's freakin sweet! I love the open diff used as an automatic shifting mechanism. If you had made this 70 years ago, it would have been on every offroad-duty truck in America.
And yet again a guy who knows where he’s talking about! I want to ask the viewers to learn forms these kinda guys whom are showing us tons of informations not asking for loads of money like some of the MOC builders do, but share it with us, free! These kinda guy’s deserves lots of thumbs up 👍 So for this, well done my AFOL friend, thanks for sharing this beautiful video with us.👍👍🇳🇱
Brilliant. It's been a long time since I've played with Technic, so I didn't quite remember how the differential parts worked - so it took some thinking to understand how the arm is moved, but it makes sense! Very cool!
most wonderful part is that, when gear is moved to the gap between diff and other gear, the whole thing becomes like a cvt due to both differentials. so technically this whole concept is a cvt gearbox . Well done, sir, beauty of engineering.
@@Cobaltthefluffywagon well yes, but actually no. At the time of the comment I did NOT notice that the first differential was not connected to the drive shaft directly. But it's very plausible to create a cvt using 2 differentials.
This isn’t a CVT. there are no continuously variable gear ratios. The ratios are discrete. If you had a CVT it would not just snap into a gear, it would glide continuously between different ratios.
If you make that video just say," While I was working on this I saw this guys video(link). I guess I'm not the only person thinking about this...(or just put it in the description)" Then you can give credit while not diminishing your own creativity.
This is amazing to look at, as a layman (that's the correct term, I think) like myself. Especially after watching that Jam Handy film on the no-noise transmission.
intriguing! now this I can see working on large models. There's a couple of nice gearshift technologies developing in the lego universe. Awesome stuff! I still want to develop cvt further simply because of the numerical advantage of infinate ratios, but I need to build a working brake. Theory is to use 3 diffs, one as sensor, the others as the two path ways. Then the sensor applies a brake to the high torque side, but NOT locking it. Progressive is the key, and so there are no actual gears moving, and the friction is a factor of the loading, not a constant drag. This way we get all the ratios, with little loss. Anyway awesome project, I may have to borrow the idea and see where I get to.
Very clever and very nice! The only small drawback is that it starts in high gear from a standstill instead of low gear. But it should quickly switch to low gear if the torque is high enough to start moving the vehicle anyway, but there will be a small delay. Thanks for sharing!
That's a very clever design! I still need to visualize why the arm (that locks the output differential) doesn't oscillate back and forth, from the moment is unlocks the output differential.
@@diywalkers7898 hi! long time no hear. Hope all's well? I saw something like that and thought it impressive as a prototype - but for my way of doing stuff I wouldn't post a prototype, I keep I hidden until the big reveal. Ok I did my MK1 walker and posted that before it was anywhere near polished, but that was an exception. Hello Max! what are your thoughts? 👍🍺🇬🇧
How a little bit of spring can take a big step . Changing the gray colored 8 tooth gear to a red colored 8 tooth gear would help. The red version of the 8 tooth gear is frictionless so it can slide with ease on the axle

I can see automatic transmissions in my lifetime. Wonderful :D
nice compact gearbox! No slipping, awesome
One of the coolest things I have ever seen!
The idea of using two differencial for the smooth operation is ingenious!
popped up in my recommended, gained a sub. good job algorithm and too you my good sir. looking forward to watching ever video!
Wow this is super clever, it took me a good while to understand the principle behind this. Might try it one day, when I've found the damn spring.
Great but quite simple, that is the best combination for any reliable mechanism!
Awesome work my friend!

Nice piece of engineering.
Nice engineering👍
i learned so much about gearboxes by watching lego videos
Lego is amazing !! Really cool 😎
Nice job!
Thats amazing!!!
It's the PowerGlide of the Lego World!! Sick Build!!
For it's simplicity, it's a very interesting piece of engineering.
My favorite design so far :)
If there is a will, there is always a way...
Very cool, done with "just" LEGO.
Truly amazing mate.......
Amazing!! Well done! Thumbs up from Denmark ;.)
Subscribed! Nice work 💪🏼
That’s brilliant!
This has got to be the smartest thing I have ever seen on LEGO. Hats off to you, sir
Then you havent seen very smart things in LEGO xD

I've never seen a makeshift 4x4 drive in lego form... This is just brilliant...
Genius. Always wanted to build a manual when i was a kid did not have enough gear but an automatic. Omg
So feicking unbelievable
Clever, nice idea.
I have too little brain cells to understand anything technical about this but this is an awesome design
I bet you do. Just keep learning!
@@MaxBrix The right attitude.

WOW 😳🤩 .. I‘m speechless 👍🤙
Very nice
That's nuts. Never would I have guessed... With Legos...
That is awesome
You made a automatic gearbox
I’m impressed
Omg I need to build that right now
Dope dude
oh my god that is genius

Is a very cool video.
Very clever .
smoooooth
You have made something that would take Lego another century
I think some of the first auto transmissions were 2 speed that shifted down with torque.
I have a tiny CVT that works in a car for the next video. Then no more gears!
I wanna see this! hurry up and post it! 👍🍺🍻😀
@@carlbModels The functionality is not quite there yet but it functions.

Hello Max! what are your thoughts? 👍🍺🇬🇧
Hey Max - I asked a question clumsily in this thread (I think my comment's alert went to CarlB?)
Lego should reach out and sponsor a lego kit to make one of these incredible prices of Engineering!
so cool
that is actually pretty wild. idk why but i would figure some sort of visible shearing would happen between the plastic gears.
1diff is analog torque mesuring device. 2nd diff assembly is a 2speed craskgearbox with input from the torque meter.
Smart and compact i like it
sick af
Two minutes ago I didn't know that my life was incomplete.
Genius
Would appreciate a tutorial on building it, i’m to dumb to figure it out from a video and I would like to try it
That is super smart. An automatic transmission with only 1 motor
Briliant
Smooth gearbox, grindy worn synchros money shift explanation Xd
That's clever
Thats smart
that's the kind of dude we need to build the new world
MadMaxBrix Lego apocalypse.
So smart :-)
How does the torque force the shifter upward?
Nem szoktam legókat nézni de ez technikai újítás és érdekel elképesztő!
Köszönöm
That's clever...
That’s a fantastic and clever little transmission right there!!!!
So as there is more resistance from the carpet,the motors are geared down for more torque so that the vehicle can drive over the carpet?
Question, can I use 2 one in front of the other for a heavy vehicle for more torque? Jw

My grey gear is frictionless. But for those that don't like modding, great advice.
I’ve got to put one of these together. I’ve got several places it would be perfect for.
