if i put this on my car it's heavy i weight 1kg does it go faster? or stays at 1:1 fear ratio ?

Also no mather what u use ur limited by traction

The one with aded with yellow gear can be used for dct transmisson

solid design wonder if you could make the bottom 1 2x1 instead of 1 1x1 and 1 bushing

Everyone makes the same mistake... In an OPEN differential, BOTH axles get the SAME torque, no matter what!! In other words, the torque does NOT get divided by both axles as it is claimed in this video (0:25 and 0:55). However, the power gets shared, 50-50 in a straight line, both tires with full traction, or 0-100 (0 being the non-moving side). For example, if you lift up one tire, there is almost zero torque (just enough to overcome friction) on BOTH axles. The opposite side has traction, but since almost zero torque is not enough to move the vehicle, that tire does not move at all (almost zero torque, zero speed, zero power). The lifted tire rotates at a higher speed (almost zero torque creates high speed, remember Power = Torque x Angular Speed, so Angular Speed = Power / Torque, and if you divide the power by almost zero torque, you get a relatively high angular velocity), and all the power from the drive shaft (assuming 100% efficiency) goes to the lifted tire as wasted energy because the vehicle does not move. Note: the opposite tire consumes ZERO power (because of ZERO angular velocity), that is why all the power from the drive shaft goes to the lifted tire, and that is why the tire rotates 2 times faster than it would normally rotate. I hope this makes it clear. Torsen is different. It "sen"ses the torque difference. Typically, there is a 1:3 Torque Bias Ratio between both sides.

It should’ve had a longer tail, then the structure would look more like Anguirus’s structure… or something. Idk.

Does the lower gear create more torque?

Gracias, realmente gracias, al ver este vídeo me ah ayudado para un proyecto que tenía a se mucho tiempo, y gracias a este video lo podre hacer, eres el mejor.

...why not use gears and oil? or even make it so that you have a stack of gears like a bike

This is tge beat gearbox I've ever seen like how did you vome up with this its so genius

Very nice explanations. This is the first time I have ever understood how a CVT works.

Good explaination! Thanks

Very well explained! Thanks!

If we replicate this in a bigger set, and put this original in the middle, can we get a 3 speed gearbox?

So, it's more like a clutch slipping than a gearbox, since a gearbox is supposed to increase torque wile on lower gears, not the opposite like here where power is getting lost at lower speeds...still, interesting solution to avoid stalling the motor

Could you make a tutorial please I need this

Sadly very inefficient. In low gear a lot of energy get's lost in the transmission, resulting in only a very slight increase in torque at the output compared to high gear.

The ball looks like an apple 🍎

Hi. I found this video because my son's 42114 is not functioning properly, so i searched about differentials. When it was new, the 42114 could go over obstacles easily. After about 1 month time, it cannot go over even a pen. I checked the gears but couldn't notice anything wrong. Do you have any idea what the problem could be? Should I reassemble the whole hauler and try again? He is quite frustrated, and so am I. Thanks for reading, and I hope you can give me some insights. Thank you!

Parts list?

i am speechless about this auto-gearbox its... unbelivable simple

O went on AliExpress and bought 10 of these friction gears right away, thank 😂

Really clever! Nice and compact, simple, efficient. You can put more than one in a row as well.

I have watched this (and similar) video(s) multiple times and I still don't understand a part of it. I do understand how the gearbox works but do you actually get more torque? I am starting to become confused at 3:13. If you have the driving force in the engine and you simply divide it in two pathways why does it get more powerful when it goes through only one of the pathways? Is it because you have a high gear ratio in the second pathway (lower path at 3:55) and when you "turn it off" via the clutch you get the full in the first pathway? As a thought experiment, if both pathways have the same gear ratio, it wouldn't increase the torque, would it? And some of the power goes into the clutch as friction, doesn't it get worn out very quickly, have you used it in an extended period of time? Thanks!

It's funny to me how I saw this Video years ago and when I needed this I was able to find it so easy! It's an amazing Idea for a CVT and this never really left my mind. I wonder if the parts can be changed out to get more torque since I would guess that this example slips easily because of the parts used.

Amazing, brilliant and genius.

I am impressed. Thanks for sharing this amazing automatic transmission idea. I will definitely use this design and will pray for you when having fun. Awesome :)

What will happen to the low ratio if you double up the white slip gears and another gear to connect to the white gear ofc

If you put few of them in series, will it become 4 speed or even 8 speed transmission?

this is NOT how torsen/helical LSDs work there are no wormgear/wheel pairs in a torsen/helical diff, no gear pair in those diffs approaches anywhere near the gear ratio a worm wheel/gear pair has Torsen/Helical diffs work because the helical cut gears (which look vaguely like a worm gear in that it's spiral-y but not nearly as aggresively) generate significant axial load and thus friction against the differential housing when load is applied

And always remember to sync your balls guys! Jokes aside great video, really cool little transmission

Is the clutch gear a must have?

take care: in an open differential the torque provided by the power unit is always distributed 50% per side in every (but really in every) condition, even if a single wheel is slower, blocked or turns in the opposite direction.

So, if you were to put one of these gearboxes on both the front and rear axles, and then a third one to split between the axles as a transfer gearbox, you could theoretically put all the torque into a single wheel if the other three were slipping? Sounds like the ultimate 4WD to me.

It would be interesting to see you use the flyweights to maintain a constant output speed with variable input speeds.

great idea, i have to test it out, but isnt there lot of power lost by slipping the clutch?

This is wrong idea because friction on lower gear don,t make output stronger, low velosity only.

For the standard you can use the locked difrential method

amazing!!!

whoa!!!! my son will love it!!!

Awesome videos, thank you so much for share.

Tutorial?

That first gearbox is in a Lego set I have

Instructions for the whole car?

rly good but looses 2 much energy over the slow-clutch-way..

Would be great if you add a torque sensor made out of a differential and an elastic band (Kinda I saw in another video) to control the cvt automatically

Yes this is the right approach when you try to use a differential like a gear box, (in the lego world)

This makes me want to take engineering in college. But I already know how depressed engineering students are.

Suspensions on the wheels will make it go up that ramp.
