Case IH Magnum Tractors with CVT Transmission

3:06 "100% mechanical efficiency" - from now and on will not believe to any word on this video.

[@SvyatoslavKonev]

Они имели ввиду высокий КПД планетарных передач, до 99,6% Естественно 100% быть не может...Видео в целях рекламы, а не описания

[@paull7775]

You are right. I had to go back and listen again. For some reason I took it to mean 100% mechanical not 100% efficient. I think there is little question that mechanical is more efficient than hydraulic but nothing is 100% efficient.

[@nonyadamnbusiness9887]

@Bobby Sue "we achieve 100% mechanical efficiency" is exactly what it says.

[@mitzvahgolem8366]

Awesome! Looks like fun to rebuild someday...lol

[@nicholasfry8695]

ya don't rebuild it, ya buy a new one. lol

[@interman7715]

These seem to be one of the better cvt's but I'll still take a powershift or partial powershift.

[@connerbrandl5103]

Agreed

[@MetrologyEngineer]

2:51 Don’t let their wording deceive you when they say “100% mechanical efficiency” that’s doesn’t mean the transmission is 100% efficient. It’s more like it’s 100% of its maximum efficiency and its maximum efficiency is definitely not 100% ‘energy’ efficient (for lack of a better word).

[@randallbyrd1973]

Very nice TY for sharing

[@halflife103]

gonna need one of those 1950's chevrolet videos to explain this shit

Hello could make a video of how to calibrate the ranges of the case ih magum 235..

transmissão perfeita

[@ADRIAAN1007]

Nothing is 100% efficient. There will be heat and friction loss in the transmission.

[@connerbrandl5103]

They said mechanically, idk how that works

[@austinpaxman503]

@@connerbrandl5103think of a solid shaft. An engine rotates that shaft at 100rpm. That shaft then rotates a pulley at 100rpm. Since the shaft is solid and both turn at the same speed it’s 100% mechanical efficient. Same concept here once they match speeds they are 100% mechanically efficient

[@connerbrandl5103]

@@austinpaxman503 thanks for reply, I’ve actually gone to fox valley and learned in pretty good depth from cnh how the cvx/cvt works. This last year, I hadn’t when I commented.

[@涂寒冰]

Good ! Thank

[@actorzone856]

Its a electronic powershift transmission, same as the rest except the Fendt CVT,

[@brianschulz4271]

Fendt CVT is way simpler, with no clutches,and no shifting ranges..

[@motorist0278]

yes but it need more power from the engine

[@bartdereu]

You would think so, but several tests have shown that it's the most effecient CVT in total. Some CVT's will win this in some area's of speed, but overall the Fendt Vario will win.

[@ukaszsiwik7410]

Fendt 0 case 1

[@omartavano7835]

Credo sia zf costruzione

[@bledlbledlbledl]

"Hydrostatic" ?? is that the same thing as a variable-displacement pump such as the adjustable-tilt-plate pumps some mowers have? Or is it more like what a torque-converter does? or something different altogether?

[@Sausketo]

This would most definately be a swash plate type pump with all the cylinders, its the only pump you can "throttle" at a constant rpm

[@AndyFromm]

Why isn't this making its way into commercial trucks?

[@ccclc6159]

some cars have cvt but I suspect in trucks expense and reliability issues would be the 2 biggest reasons, another issue could be the truck slowing down too much when the transmission is trying to find the most efficient speed? if the truck maintained the speed or flow of traffic any efficiency that might have been gained is lost?

[@AndyFromm]

@@ccclc6159 if it would hold up, I'd think it would be idea. Hold the engine at peak efficiency or power during acceleration and peak braking on deceleration.

[@fransboshoff7700]

Beyond expensive to repair..

[@MrMarkguth]

Why did case decide to put their fwd/rev in such a weird spot? It’s awkward

[@nkagisangsiane381]

can i please know a basic power transmission of CATmachines

[@mitzvahgolem8366]

[@25gwolfable]

I don't understand why it's called a CVT when I don't see any form of CVT belt chain or otherwise I'm just saying

[@tedkahler9738]

Constant Variable Transmission.

[@bartdereu]

It's not using a belt and a variator like you know. It uses a variable hydraulic pump and motor to change the speed of the outer ring of the planetary gear. That way, mechanical power transmission goes from 0-100% in the range .(0% at start, 100% at full speed of that range). When it shifts to another range, it starts again in that range from 0% mechanical to 100% mechanical. Therefor , you can drive at 8km/u 100% mechanical , but at 9km /h only 10% mechanical. In a fendt vario , the procent mechanical power transmission is constantly increasing with it's speed, according to on of the two ranges (0-25 or 0-50 kmu)

[@Bad-eb1dv]

ED 25 there is more than type of cvt

[@nonyadamnbusiness9887]

@Bobby Sue What are you about 13 years old? Practicing to be an asshole when you grow up?

[@nicholasfry8695]

You see Cvt means continously variable transmission, there are many designs for powershift, who said there is one set design for cvt

[@nagyandras8857]

i rather trust a simple 4x4 snychromesh.

[@JCB411abuser]

Nagy Andras imagine having no synchros to fail or shifting forks or linkages. these new boxes have more reliable components that shouldn't wear as much if looked after

[@nicholasfry8695]

maybe but imagine trying to unload on the go with that, or do many other tasks that these do easily, we plant with a cvt and do odd jobs with a different cvt tractor, this transmmision makes a powershift look like garbage

[@nagyandras8857]

@@nicholasfry8695 i do odd jobs, with an 18 forward 4 reverse manual gearbox. and its not even synchro. had a tractor with cvt. the cvt was the first thing that gave up the ghost. glad it suits you, but it does not suit me ;)

AH, what that der yer talkin?

[@cruisingdanny4974]

The think apart from being so expensive if this transmission fails I dislike most, is the fact you are no longer being challenged to become a great driver. Nowadays you just hold the throttle, thats it. Where is the challenge into mastering the skills of driving? Quite boring to be honest.

[@Bad-eb1dv]

Cruising Danny we’re the standard Me and your tracker transmission with for ranges and for gears in each range

[@nicholasfry8695]

Who said that we need to be challenged while driving, these are way better than any outdated powershift

[@damgnj]

Good animation, poor explanation !!!

[@jason.arthur.taylor]

Neither is any good boss. It's not even clear to me that this is a CVT.
