Continuously variable transmission

good animation, bad design concept.

Tokyo Mitsubishi raja ridu

Amazing

Why don't you make an real project?....

Интересно, как добьются равномерного выдвижения 12-ти поршней, ведь нагрузка на них ремня будет неравномерной.

Please keep music out of vids, This is an intelligent design & folks don’t appreciate the added music.
Thanks.

🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️

I have design one similar but it a 2 speed for my project. And it need a lock and pulley ideler wheel on the slacker side, or bottom on mine.

Guys I have a question. Wouldn't this work if it was a regular belt instead of v ribbed?

great

It will be so much vibration

magnificent

no veo la aplicación practica si la polea que debe ser fija tiene que desplazar su eje hacia adelante en un avance a medida que la polea variable de agranda

,✌️

In high speed, belt teeth and pullies holes, won't exactly FIT.
Will wear out in 1 Mile.

After 300-500 rpm starting vibrassion.Not logical

👍👍🌹🌹🌹Guy🌹🌹🌹👍

Uh

First thing wrong is it's belt not gear driven. Belts will break, or stretch, ect. Your going to have problems. The car makers don't care. They no longer make cars to last. 75% plastic. Death traps. Yeah the old battle wagons, big cars of the 60, and early 70s drank gas, but you didn't have belt driven transmissions. Who's stupid idea is this?? But you sheepeople the blame for it. They make it, you sheepeople buy it without and questions about how many miles before you have to change the belt. Like a lawnmower!!!! Car makers don't care if these car are going to last. They build em to throw away after a couple years and you sheepeople never get the. Paid off. It's all planned out. Buy junk, you get junk!!!

Kudos to the ingenuity, but too many moving parts. Plus oil and seals are involved, opportunity for leaks.

Even if it did work it wouldn't work for long. That's a lot of unnecessary moving parts. Let's just go with the proven method

Great applied to a bicycle!

Golf cart transmission with a big rubber band on it HA HA HA HA!!

This design is a disaster, ask any
machanic. Made by Jatco and always
failing after 100,000 miles.

traslate to spanish: traccion continua.

This is brilliant, for sure. But the fact that the outdrive has to move towards or away from the source as the gear ratio changes makes it impractical for many applications.

Harmonics, control and all that aside, biggest issue I can think of is the fact that it would have extremely little contact area of the belt on the driven side. The amount of power you’d be able to transfer at the driven side would be near nothing compared to the belts theoretical designed rating. Contact area and pulley wrap is everything in a belt drive, especially a cog belt, and this design has literally none of it at the driven end

Christ they make eight speed automatics nowadays if you need more than eight gears than you've got bigger issues going on.

now you just need an engine that slides sideways

Just trying to figure out what this would be used for, a motorcycle transmission comes to mind. But, it does have some flaws. Too many moving parts.

Каждое изменение диаметра приводит к повышенному износу ремня...

Я об этом 20лет назад знал

What's it going to hook to though? your output/input shafts move.... Going to find a fit for something that can use that is going to be hard.

おーい　間違ってないかー？

Centrafug compressia?

brilliant, this just may save the cvt. does anyone know if there is a mechanical seal at the oil input or a labyrinth type

Spielerei, viel zu teuer und daher nie konkurrenzfähig zu den längst bekannten, komerziell genutzten Variatorgetrieben!

Durabilitas dan ke gagalkan sistem dan terlalu banyak komponen.. .. problem mesin ini

Saying the rubber band broke wont be a joke anymore

Não entendi a idiotice do uso das polias no setor variável. Se fossem funcionar como tal, o eixo de tração não funcionaria.

Um, this is not what a CVT looks like at all, this mechanism would just fly apart unless it’s for a bicycle?

Нихуя не понял
Но очень интересно

This mechanism will not work as envisaged in the figure. I can't speak English. It's meaningless to write a complete explanation. You won't understand. I am a technician with 20 years of experience. I tell you that this mechanism does not work. The speed at the outlet will jump continuously, and when six pistons are connected, the belt will wedge in a specific position.

Мне кажется, такая трансмиссия имеет существенный недостаток. У нее не зафиксирована вторая ось. Получается, ее невозможно поставить, скажем, между двигателем и колесом, потому и тот и другой не будут сдвигаться друг к другу. А что мешало сделать сразу два колеса с раздвижными ступицами? Тогда расстояние между осями было бы неизменным и эффективность выше за счет одновременного увеличения одного колеса и уменьшения второго. Кроме того у колеса с раздвижной ступицей зачем было делать шестерни? Он же все равно не вращаются. Достаточно было сделать неподвижные башмаки с зубьями под ремень.

A lot of free good comments.

Quite fine but transmission ratio is not constant for given shape oh hexagon wheel. Cvt is better here.

What animation tools used for this demo?

To je docela k ničemu ne? když osy otáčení nejsou pevně uloženy a cestují... To někde reálně funguje nebo jen ukázka, co umíš namodelovat?

Whats the point of those 6 small gears? If they can be rotated freely, then they wont drive the belt. Aside from that, the design seems to be very bulky.
