- This is my LEGO 2 speed automatic gearbox that does not use a limited slip differential.

Thanks for watching!

That is soooo cool,
and the instructions, that is so cool too, reversing it makes it so satisfying
Is the assembly instruction actually a reversed clip of disassembly? It’s like wonderful magic tricks!
Yeah! It’s the easiest way to make buildings Instructions😂
@@DumbleDork I laughed so hard because it looks like you are adding the bricks with very much speed xD
duh
@@darvinde I tried that once when I was like 12, very painful
@@DumbleDork and it looks cool as hell
Really appreciate this :)
Hey could you make a 3 or more gear automatic transmission ?
Cool! Is there any way to increase the 2 speed to 3 or 4?(without differential)
me again, does this handle reverse motor direction as well? I'm thinking of adding a gearbox to my walking machine and your version is nice and compact 👍🍺
Yes, it seems to me like it locks the gearbox on the 2nd speed.
@@npljojo there appears to be a.problem with torque sensing with Lego. I'm kind of feeling like quitting on automatic gearboxes as they can't handle rpm (power) and the motors I am using are 10x, even 30x the reg limit of the puny Lego motors. After a lifetime of supporting Lego, I'm officially bored and frustrated with how feeble it is compared to RC modelling.
Is it possible to build instructions or more detailed photos?
thx
Your welcome
amazingly compact set - how does this work in reverse? i'm looking for a compact working solution to try and install on my modified version of the 8880 supercar
I just build it, super cool, but does not work in reverse
When i put resistance on the output, the output gets faster - it should get slower so it is stronger up a hill, so there would be no benefit???
You've flipped a pair of gears.
it looks like when the box is shifting, the direction is change from the output... ??
No, it’s the same
your right. it turns the same direction. i made one, modified it a bit because it turns to fast. and make is shifting with a shockabsorber instead with a rubber band. but my rc 4x4car is to heavy
@@DumbleDork no it changes, buy glasses
@@curtisnewton895 I already have glasses
It doesn’t change… I built it myself and believe me, I know
@@curtisnewton895 It doesnt change - it looks like it does because of the rpm of the cog and the fps of the video combined
What are the two ratios (default gearing?)
Depending on which ratio you use. To calculate LEGO gear ratios I'd recommend sariels gear calculator.
Dumble: as you can see it doesnt have a differential. Me who doesnt know what a differential is: i guess im blind then :(
It is a part in most cars that allows both wheels that the differential is connected to spin at different speeds, which helps when a car is turning, but it is not good for offroad. If you search “lego differential”, you will see what it looks like and there are some videos that might help you to understand what a differential does
The gears keep slipping away
Mine makes a horrible cracking noise,can anyone help?
This is normal. In the first and second gears of the gearbox, there is an intermediate section (between the gears corresponding to the first and second gears). The movement of the gears in the first and second gears is not synchronized, which consumes some traction and changes the movement status, causing the gears to jam at that moment. This is unavoidable unless you use a gearbox made of a differential😅
completely useless as the rotation gets inverted
