I have a question regarding the CVT shifting control. Let's say it's shifting from a low gear to a high gear. How does the computer decide the speed of the...
Bonjour, IMHO, 1) If you want maximum power transfer, the engine shall turn at max HP rpm. Period. 2) If you want maximum acceleration but minimum consumption,...
PerfectObsession2004, Very clear statements. I've been ridiculed (maybe too strong) for saying similar things (with different words) is another forum. For ...

PO, I'm not really sure what you meant by this: <snip>You have both parts of the previously stated equation.<snip>. I understand that "A well calibrated cvt...
Here is the equation: <<demanded "car" torque equal offered "wheel" torque>> Left side: car's mass times car's acceleration is the force applied onto the...
Hi all Its only about 5 months late ;), but at last we have run our cvt (which we call an svt for some obscure reason) at around 120kW with 2700Nm through it ...
To carry this thread forward as requested, I believe you when you say that this traction control idea is possible, but is it actually happening in a car like...
Hi, I wonder how the torque output graph of a 4cylinder engine looks like. For example, when they say the engine delivers 200 ft lb of torque at 3000 rpm. Is...
Ok! Let's go for traction control Vs CVT ! To help understand controling traction or not, I will talk about, first, race snowmobile (dont) and, second, race...
I'll simply say "Thanks, PO" I'm seeing a new view into these devices. You are really saying here that to have traction control differentiated left and right...
PO, Very cool website links! The first one is broken (gives an error "Error 404 occurred") but the second has quite a good collection of DAF pictures and...
... That's a neat site. I'm kind of curious, how did reverse work on these cars? If the CVT could be made to handle more power, and tuned appropriately I...

OK, now we're back to where I started. That DAF F3 photo needs some explanation, as may the DAF33 or DAF55 photos. In the road car pictures, drive is split...
Q: Do the rear pulleys, the driven clutch, move up and down, independly, with the attached wheel? A: Yes. And belts will shake on bump too. Q: What is the...
PO, So you are saying that the F3 car is not transmitting power through what appears to be a single differential? Are there two paths for torque to flow? How...

OK, I like this. That means that the center case we can see in the picture carries TWO torque paths ("fixed ratio [a single gear at each end of that tube?] ...
Who are the leading manufacturers of CVTs? Ford seems to be adopting them broadly for the Freestyle and 500 and I'm curious who is building these sliders......
