HI: I am the group photo MoBike CVT guy. Please help me find a name for this. In following the discussions recently involving one way clutches and one way...
Hi i am a current student of mechanical engineer in LOS ANDES UNIVERSITY in colombia, my final work project is to design and construct a cvt for a 2 wheel...

Is there anybody familiar with geared CVT's, especially epicyclic or differential types with dual transmission paths? What are the problems with this type, and...
The advantabe of an eicyclic differential split power transmission is the theoretical capability to vary output speed from zero and the multiplication ratios...
i ve been using this page so far, but i wanna know in the input pulley i should put a clamping force for a given ratio and for a given power at that rpm, but...

Thanks allot for your reports and impressions John and Jim. I would be very nice if some members ho visited the conference; if they want to post some pictures,...
Hi Huw, Thanks for the link. What I'm talking about is a purely geared CVT, no hydraulics. Power is split through a differential or planetary gearset, one side...
Jerry How do you propose to control the the speed of one side of the planetaries? What you describe is exactly what it is that CVT engineers do anyway. The ...
Hi Paul, Thanks for the reply. The patent I mentioned is an epicyclic differential split power transmission. The power has two paths, one way through the...

Hi Dudley, Thanks for the reply. Yes, it seems as though you need a CVT to control the CVT. A flywheel or generator on the low gear side is the simplest, but...

Hi Omar, Looks like the formula is at the bottom of the page. Axial clamping.force = ( Pe/Belt_speed )/ mu.e = [N]. Or (HP divided by Belt Speed) Divided by...
Hi Huw, Yes, an electric motor would be nearly ideal for controlling a dual path transmission. It would be stepless and controlled by an array of sensors. I'm...
Hi, I want to know the relationships between between gear ratio, engine speed, vehicle speed, and power requirement for a theoretical vehicle with an "ideal"...
All differentials split equal power to all shafts all the time. If all output shafts do not contribute all power directly to the final total output that is a...

Hi Ken, If you lock one of the differential output shafts, doesn't all power flow through the other output at twice the speed, and half the torque, with only...

Yes, that is true, and might be considered the only exception to the rule, but in reality it is not since the equation cannot consider a non rotating shaft. In...
Let's say a gear is driving a rack in a rack and pinion system. The gear delievers a certain torque and this get translated into a force on the rack. But I...
Ken, I disagree with your statement on equal power going through a differential. The classic differential on a rear drive vehicle supplies an equal amount of...
