For any CVT owners watching this, change your CVT fluid EARLY and often, using the dealer supplied OE fluids. I recommend every 30-35k miles for most drivers. Some OEs state longer, but they aren’t the ones paying for your $5k USD transmission if and when it fails. Keeping clean fluid with the correct formula and viscosity is about the only thing you can do to try and prolong the life of these things. Honda and Toyota, two of the most highly regarded brands for reliability, have had a hell of a time producing a CVT that can consistently make it to the 100k mile mark. Nissan’s CVTs…I won’t even comment on here. Buyer beware when you’re shopping for your vehicle. CVT is becoming the norm behind 4-cylinders, and it’s still a mixed bag with an unproven record in 2023. Thank you guys for putting this video together! I will share it with friends and customers to help them better understand. 🍻 ✌️

[@KevinATJumpWorks]

The great thing about those things is that you use centrifugal forces to change the transmission ratio so that, for example, the motor always operates in a high-power rpm-band. Most non-electric scooters use such a system. You can adjust the target motor rpm by changing the weights of the centrifugal assembly.

[@actuallyn]

yes but you are forced to cruise on higher rpm (at least on scooter vs motorcycle) and if you want to change it’s “personally” again, you have to tear it down and modify it

I mean it really depends on how you drive and the specific CVT. I personally don't like CVT transmissions (especially the fake shifting). But some people can get away with it if they drive like a grandma and get improvements in efficiency. However it's not worth the tradeoff to me.

It is amazing how such a thin and small belt can transfer enough force to drive a vehicle that weighs thousands of pounds. These transmissions are amazing that they work so well. I realize there are long term reliability issues with CVTs.

[@WeberAuto]

Thanks for watching

[@Jeremy.Bearemy]

Its interesting how it's all designed. Part of the reason the belt can be so small is because it's spinning much faster than the axle. If the wheels are applying hundreds of pounds of force to the ground during acceleration, maybe there are only a few dozen pounds of force on the belt depending on what the reduction is. But all the energy going to the wheels must come through that belt, you're right. It just spins around a lot more than the wheels in order to convey that energy

[@TheKnobCalledTone.]

Long term reliability issues boil down to the manufacturer, as well as how the individual transmission is serviced by its owner (or owners). Honda CVTs can last a very long time as long as the CVT fluid is changed on a regular basis, using the correct OEM Honda fluid. On the other hand, Jatco (Nissan's transmission OEM) seems to use rubber bands in their CVTs, and no amount of maintenance can protect against that.

[@thx1138guy]

I know the guy who held the first patent on a fully functioning CVT and demonstrated it at a World Fair a long time ago. I don't remember what year and he may have passed away now, he was already quite old when I met him in 1999. Somehow his design worked without pulleys and belts and was supposed to be far more mechanically efficient and reliable than the belt design. He had a treadmill with a manual CVT in his apartment as his remaining piece. I struggled to understand the design, and had been attempting to invent one myself for use in heavy duty situations. The man was a genius. The belt driven designs initially were not efficient because of the friction to create gear ratios and reliability was an issue. I haven't been following the auto industry as much for the last 20 years, but I think those are still the same hurdles.

[@WeberAuto]

Thanks for your feedback! Very interesting!

[@ianrasmussen5380]

I know this comment is 5 years old, so I apologize, but would you perhaps be thinking of something called a "toroidal CVT"? I remember seeing a video of it a while back, it's used for much heavier duty situations. Doesn't use a belt at all, instead it uses some kind of friction from spinning wheels, so it's much stronger. I think the Japanese military's main battle tank uses one (which means it can go just as fast backwards as it can forwards, which is neat).

[@superturboawesome1]

@@ianrasmussen5380 good evening, I just googled a toroidal cvt and although this is more on par with what I originally described, it isn't quite the same. Bill Glazier's CVT employed a lot of sprag shafts, or sprag clutches, and to this day I still haven't been able to "crack the code" and decipher how he incorporated them into his design, but I think there was still a lot more to it, unless the toroidal video I viewed was an oversimplification.

[@arkansasmountainman]

When I was a teenager, in the early '60s, I had a Rockford motorscooter that had an automatic transmission based on this principle. The faster the engine turned, the V belt went outward on the engine side and in on the drive side. No shift points just smooth starting and driving. It worked with weights and springs and was base on centripetal force on everything. Not nearly as complicated as this but very similar. As the RPM increased on the engine shaft, weights were pushed outward on the variable pulley and the V belt moved closer to the spindle, this pulled the other end of the V belt into the variable pulley on the wheel. A complete transmission rebuild consisted of replacing a very easy to access V belt.

I had a 1984 Toro lawn tractor that had this very same setup. The transaxle only had forward and reverse, there was no gears, or speeds. The clutch was the control - the further you let the pedal out, the faster the tractor moved. If i remember, the more tension in the idler (driven) variable pulley, it would open up making the driven center smaller, and directly changing the speed the transaxle was spun. It had a really wide V-belt, the whole mechanism looked just like this.

Practically what to expect from a CVT Transmission: - Delay or lag throttle response from a stop acceleration (hazardous when making a left turn at a junction). Delay or lag throttle response for clutch to grab when going to reverse (fellow motorists have to wait on you). - Sooner transmission fluid & transmission filter change intervals. If you a Do-It-Yourself, drain and drop the pan, change out the trans filter, clean out the magnets, add new and correct trans fluid with the exact same amount of old fluid that came out, damp your new trans filter with the new trans fluid, and torque everything to specs. If you're a Go-To-Dealership, than you can only hope IF your fluid is actually changed or did you pay to just have your car sit? And the magnet clean & filter change thing with the dealers, forget it! Best case scenario is just a fluid flush. - Metal chain (belt) constantly moving & rubbing up & down along the inner sidewalls (variator) of two pulleys. Let's see if most CVT can handle up to 200k miles that most standard automatic transmission could without repairs except for fluid maintenance and at normal driving stress. Only time could tell!!! I think there's a reason why some CVTs are discontinued on a same model vehicle platform, for instance, an Audi A4. - Low rpm at cruising speed (saves fuel). So does an automatic or manual transmissions with 7 8 9 10+ gears could cruise at low rev-per-minute as well. - Less cost & parts to manufacture saving auto maker companies manufacturing costs. As a result increases their profits. How about you as a consumer? Take 2 vehicles with equivalent comparisons except for one is equipped with a CVT transmission and the other with a standard automatic. Does the vehicle with a CVT selling price less, more, or same? Even though a vehicle with CVT costed less to manufacture. Do the same comparison between vehicles with a 9 speed and a 6 speed automatic transmissions. I reckon the answer is cost doesn't change for the consumers. Just more profit for the auto companies.

It makes those type of vehicles very responsive to throttle input. From what I have seen for automotive applications, it really inhibits performance. It might be quite fuel efficient, but its not nearly as reliable as a normal auto transmission and acceleration is painfully slow.

[@WeberAuto]

Thanks for your feedback!

[@dhaynie266]

bigger pulleys, sheaves, and an appropriately size (this one is way under what should be used, and is not much bigger than the one on my fourwheeler) belt would make quite a bit of difference. more power could be moved, coupled with a higher ratio and more aggressive tuning for the cvt, and would result in much better performance.

Why don't the car manufacturers take the torque converter type of system that was used on gas powered golf carts and make it work in a car?

[@user-wk4hf7ng9z]

Не. Тут система такакова что в зависимости от оборотов подается разное давлние жижи. Это у механника компрессор с одним давленем. Вот в зависимости от давления и происходят плавные изменения передаточных чисел на валах. Нету ни пинков ни подергиваний..

I think the CVT design is so cool. It’s so complex but so simple. I love driving a CVT vehicle. I really enjoy it’s rubber band effect when accelerating.

Just wait until you have to replace your rubber band trasmission. There is no better trasmission than one that has actual gears.

[@csnoopy]

This means you can accelerate while maintaining the same rpm to stay in the power band. But doesn’t this make it really weird? I mean the engine sound will stay the same while you’re gaining speed

[@fullmetaljacket7]

Yes that's how it works. It's kinda weird but auto transmissions are weird compared to manuals, anyways. It's kinda like a moped but when you put your foot down the ecu lets the engine rev higher or when you're just cruising the ecu tries to keep the rpm down as much as possible.

Here in the Philippines, almost all brand new cars/SUV's (Toyota, Honda..ect) have CVTs. Some have already reached 10 years or more and still display excellent performance. Proper maintenance care and responsible driving practice are the key factors for CVT to last..❤

[@Opalivian]

People who buy Nissans cant afford a car and have lower education. Keeping oil clean is definitely nonexistent.

Great demonstration! IMHO, steel belt is better than a chain, because it is capable of transmitting a "pushing" effort, not just "pulling", like a chain.

Reminds me of an old snowmobile drive system. The difference being, the snowmobile transmission is exposed and dry. Uses centrifugal force to engage the cones to change (gear) ratio.

[@Justinofalltrades1]

i want a manually operated cvt so bad, invent one please!

[@zawar0081]

that's.... strange. the whole point of a CVT is to not change gears.The transmission does the magic by making adjustments to the ratio as you drive. Or am I wrong?

[@Justinofalltrades1]

well my guess was that it would have a computer telling it where to be, but i feel that there are times when i would want the rpms of the engine to be in a different spot then what it wants them to be. also i just think it would be a fun an a very unique driving experience

[@Dr_Xyzt]

Technically, this is an IVT, not a CVT. A true CVT is tailored to defined conditions, like drills on oil wells when they hit a hard spot and need to slow down. An IVT like this one is adjusted with an input like pressurized fluid, or mechanical links. It's worth like 5% better fuel economy, and a given % better 0-60.

[@woohunter1]

Subaru wrx cvt has paddle shifters with simulated shift points and can be either a "6 speed or a 8 speed"

that kinda defeats the point though. id like one that emulates a hydrostatic transmission

[@tanayagarwal6670]

So does overdrive happen when car runs on higher gears?

[@timothylloyd4625]

You can think of the CVT part of the transmission as a variable overdrive/underdrive selector for each gear on the input shaft, adjusting as needed to provide the optimal gearing for the driver's input, the engine's power band, and the currently selected gear. An example is if at the lowest CVT gearing for gear 3 is 0.9:1 and the CVT can adjust by 0.2:1 then the range of gear 3 is 0.9-1.1:1.
