No bro- Jatco CVTs in Nissans and some older Chrysler products are just garbage. Take it from someone who worked on them.

I used to think it was just Jatcos, but this recent Toyota experience has me convinced CVTs just suck for passenger cars.
CVT in scooters don't go via torque converter to connect with the ICE. They getaway with a centrifugal clutch. It's a dry setup and far more efficient than the torque converter. Torque converters with 1 way clutch included. I think some manufacturers even tried electro magnetic clutches to pair the ICE to the CVT. The day will be, when the ISG from a mild hybrid takes over during stalling speeds allowing the ICE to be paired directly to the CVT without any clutch interface. That way Direct Drive would have finally arrived in the automobiles.

Same idea as CVT was used on the Massey-Harris Number 27 combine harvester. It had two adjustable pulleys which were called sheaves. They functioned in the same way as a CVT with the pulley halves opening and closing. Forward speed was adjusted by setting the control lever to different positions. The sheaves themselves were forced into position by springs. The pulleys were connected by a very heavy belt. Slippage was taken care of by spraying some belt dressing on the belt. Very reliable technology.
Its not invented by one man...but an evolution of mechanical (automotive engg) with the contribution of several engineers during the last millennium...
@@DeltaTeamSoldier it also can't transmit much power, that's why it's mostly used in scootrs and economy cars. Williams even tried developing a CVT for F1, they couldn't find a belt material that would be able to hold up for more than a couple of runs

Some people think cvt and dct classify as auto. If they were auto, they wouldn't call them dual clutch "transmission" or continious variable "transmission"
Really is an ingenious design, used in most scooters, some cars (mini cooper, Nissan, etc.) and all snowmobiles. They have their downsides, but there is a lot of beauty in their simplicity. Their weaknesses show trying to move too much weight or at too low of speed, or being undersized.
Buen sistema para poco peso y trayectos cortos xk con peso y trayectos largos no sirve se gasta la banda y los rodillos se asen cuadrados ojalá más adelante se mejore el sistema
An imbalance in a rotating assembly, or just a guess, a belt to loose slapping around? Could be parts missing/worn/broken. They're easy enough to take apart.
Keep in fighting guys but Toyotas CVT are pretty durable. The one in my cars been there for 8 years, and perhaps over 200k miles, without any oil change 💀 . Still going strong, although will admit there is a little noticeable issue sometimes. The car will jerk a little when slowly accelerating from 10mph to above. But other than that, its still the daily driver without any issues
When I was a kid I knew why cars needed transmissions and I imagined that something like this would have to be what was inside of snow mobiles and scooters but it was hard to believe they could get it work.
Works great for light weight applications. Very cost effective for what it is. Avoid any road cars with these, they are garbage. Anyone who brings up f1 forgets that it's f1 and definitely like 100x the price of your Nissan cvt.
as a snowmobile owner i will tell you that the bands will never snap even when you are pushing 200+hp they will burn and start slipping and come of but they wont snap
@@einar8019 yep and as long as they're easily accessible, a relatively cheap "weak link" to replace. Not a huge fan of CVTs but they do have their applications.
This transmission is very efficient at converting power into heat. In my country it is very common to find a Clutch cover (or bowl as we call it) that has turned bluish with purple gradient when servicing a scooter because of how hot it gets
My mitsubishi has one of these, and with turbo and neutral shifting (I rev up in neutral then gear into cvt), I'm faster than 99% of the drivers out there. Heck, I can spin out my tires and I'm using an automatic.
I had a lot of fun tweaking the CVT on my 50cc scooter. you can play with the variator and roller/slider weights for torque vs. top speed. I miss that thing.
They have used cvt transmissions in Formula 1 cars. I think i heard somewhere the cvt was actually invented specifically for f1 cars to increase their top end power not sure how close that is to the truth, though
Nissan looked at that and said "yes! this will work in a 3,000 lb car"

This one is tuned properly, notice how the belt reaches the very top of pulley. Perfect. Would of liked to see the rear working in combination
On the edge of the front pulley there is a nest of rollers.The roller plays a role in adding/reducing torque to the cvt's energy.Scooter users can increase the amount of roller weight/decrease the amount of roller weight according to the suitability of the local road.The heavier the roller,the higher top speed.As the weight of the roller decreases,the engine power becomes stronger but the top speed decreases.
Example:
(1) If the road is hilly,scooter users can reduce the amount of roller weight to ensure the motor is powerful enough to climb the hilly road.
(2) If the road is long,scooter users can increase the amount of roller weight to increase top speed.
THE TOTAL WEIGHT OF THE ROLLER IS DETERMINED ACCORDING TO THE SUITABILITY OF THE SURROUNDING ROADS

actually i have the same scooter with over 80000 miles and no problem whatsoever
and in case if something goes wrong
then fixing it costs about 15$ here in india
Dgx fig d
Jokes on you, i have gone 559,000 miles with it. Never change anything.
(Han g 2 lakh 50 hazar). Euro 2.+1 Centribeatel left gas ⛽ centrifugal right. Electric . And fuel is it's 💶 3
Damn that secondary clutch is shot
Using the law “centripetal force” 😊
Some people think cvt and dct classify as auto. If they were auto, they wouldn't call them dual clutch "transmission" or continious variable "transmission"
Really is an ingenious design, used in most scooters, some cars (mini cooper, Nissan, etc.) and all snowmobiles. They have their downsides, but there is a lot of beauty in their simplicity. Their weaknesses show trying to move too much weight or at too low of speed, or being undersized.
Ly hợp chuyển động rất tốt 👍
Buen sistema para poco peso y trayectos cortos xk con peso y trayectos largos no sirve se gasta la banda y los rodillos se asen cuadrados ojalá más adelante se mejore el sistema
Yes
Thank you so much!
after seeing the film. what causes the cvt to vibrate at 40km/hour?
An imbalance in a rotating assembly, or just a guess, a belt to loose slapping around? Could be parts missing/worn/broken. They're easy enough to take apart.
a broken spring probably, maybe something fallen off?
I dont know bro but still every scooter have this problem at 42 to 46 kmph speed. Including belt drive electric stooters also
Motor rotator. Fuel.
High pressure high motor movement low presure low movement.
Keep in fighting guys but Toyotas CVT are pretty durable. The one in my cars been there for 8 years, and perhaps over 200k miles, without any oil change 💀 . Still going strong, although will admit there is a little noticeable issue sometimes. The car will jerk a little when slowly accelerating from 10mph to above. But other than that, its still the daily driver without any issues
When I was a kid I knew why cars needed transmissions and I imagined that something like this would have to be what was inside of snow mobiles and scooters but it was hard to believe they could get it work.
解りやすくていいね！( ´∀｀)b♥️
Bien vu,le variateur centrifuge !!!
Infinit amount of gear ratio 💖
not quite infinite, there are upper and lower limits to each side of the ratio.
The Volvo 340 (DAF) had a similar transmission system. It drove each rear wheels directly. Early 340 models didn't have a differential.
just like a snowmobile clutch you need to take apart and clean the guts in both clutches if you blow up a belt !!!
When my mechanic told me I had a belt in the trans of a Hyundai I stopped smashing out on it
принцип КПП-вариатора
30 years ago just know now
I'm traveling to Thailand myself. Can't wait to hear so much broken English in person and enjoy your country
Don't expect any changes with the CVT. Car companies are not researching and developing them. They've switched to electric vehicles.
Works great for light weight applications. Very cost effective for what it is. Avoid any road cars with these, they are garbage. Anyone who brings up f1 forgets that it's f1 and definitely like 100x the price of your Nissan cvt.
Title should be “What it’s like to have no soul”
whos CVT is this... with a rubber belt?!
They are all belt driven 🤦♂️
@@puntachu i said with a RUBBER belt... Nissan has a steel belt and Hyundai & Kia use a steel chain.. you thought you were smart didnt you
@@ArExsTee hahahaha nicely rekt
Scooters and large motorcycles use rubber belts with steel interlaced through them, even a newer harley davidson will use a belt drive that's visible.
you can clearly see the scooter's kick stand that it's on
Another reason to own a real bike! No rubber bands to snap!
This is one of the Indian scooters which lasts more than 10yrs depending on usage never heard complain here.
The gearbox will straight up not work before your to the point of actualy breaking it. Chains will snap tough
as a snowmobile owner i will tell you that the bands will never snap even when you are pushing 200+hp they will burn and start slipping and come of but they wont snap
@@einar8019 yep and as long as they're easily accessible, a relatively cheap "weak link" to replace. Not a huge fan of CVTs but they do have their applications.
@@programmingwithsunny6121 yes because a scooter does the same things as a motorcycle LOL all you goofy ass people
Hatte ich schon in meinem Volvo 340 Baujahr 1978👍
War Zoll damit zu fahren. Gleichmäßige Beschleunigung ohne Ruckeln und so👍
geil
High rpm is truly where they live, at least my 125cc scooter while commuting. Butter smooth at high rpms.
What makes the drum to move "axially"?
Thanks.
Centrifugal force makes rollers inside drum roll away from the center, which pushes against a fixed plate, making the drum move forward.
@@gabiferreira6864 Thanks for the clarification.... Keep it up...
how they ratio that? minimum maximum?
Min to max
According to the engine rpm and speed
Nice Demo, thanks
I think honda is one of the only companies that can actually build a good cvt
Toyota makes the best cvt’s
subaru better
Opened motor cycle.
A pipe to it you get air pressure for filing cylinder of your tank pipe .
This transmission is very efficient at converting power into heat. In my country it is very common to find a Clutch cover (or bowl as we call it) that has turned bluish with purple gradient when servicing a scooter because of how hot it gets
That means its not efficient. Heat causes the bearings and hydraulics to fail not to mention glazes the belt.
Activa??
Yes 👍
La cinghia sale troppo nel variatore supera il raggio massimo può essere pericoloso perché la cinghia può uscire e tagliarsi
皮帶快斷了
My mitsubishi has one of these, and with turbo and neutral shifting (I rev up in neutral then gear into cvt), I'm faster than 99% of the drivers out there. Heck, I can spin out my tires and I'm using an automatic.
Torque O Verter They Use Them on Go Carts Too 😮😮😀👍🏼
When she touches yours for first time
Tell me a normal automatic doesn’t look like it’s gonna last 100x as long as this janky shit
About the same one is just harder to fix
Normal (planetary) automatic is too bulky for scooters, though.
These last just fine for lightweight, low power vehicles like scooters. Also very light and inexpensive.
I had a lot of fun tweaking the CVT on my 50cc scooter. you can play with the variator and roller/slider weights for torque vs. top speed. I miss that thing.
They have used cvt transmissions in Formula 1 cars. I think i heard somewhere the cvt was actually invented specifically for f1 cars to increase their top end power not sure how close that is to the truth, though
Мелодия. 👍🎶🎼🎵👍
非常危險的示範啊🙏🏻
