Here's a _very_ interesting concept: http://www.fallbrooktech.com:80/NuVinci.asp Sort of makes the CVT obsolete. > Here's a _very_ interesting concept: > http://www.fallbrooktech.com:80/NuVinci.asp > > Sort of makes the CVT obsolete. You have to love it when someone comes up with technology that is simpler than that that it replaces. It's what defines good engineering, IMO. I couldn't make too much out from the article and schematic but it definitely has few moving parts. Especially when compared to a conventional transmission. I also think the scalability part is interesting. This thing can be used on everything from bicycles to semis. > > Here's a _very_ interesting concept: > > http://www.fallbrooktech.com:80/NuVinci.asp [quoted text clipped - 7 lines] > conventional transmission.

In 1956, McCulloch set up a special automotive division, Paxton Superchargers (his middle name), to handle the supercharger division. The same year the company changed the name of the ball drive supercharger to the VS-57 and developed a new variable rate supercharger called the VR-57. The new supercharger incorporated a variable rate internal planetary drive ratio that could alter the step up ratio from 3.5:1 to 5.5:1. The variable rate was achieved by a spring pack that would change the distance between the ball races based on RPM. The supercharger experienced a one-year victory in NASCAR causing officials to ban superchargers in the sport. The supercharger was most notably used as the F-option on the 1957 Ford Thunderbird (211 produced). http://www.paxtonauto.com/history.html for the complete story. It also had a drive pulley that was squeezed by a bellows. At the set boost pressure the bellows would squeeze the pulley and force the belt higher. Had a big six volt solenoid to put spring pressure on the bellows when you pressed the gas pedal far enough to trip a switch. In 57 Ford built some Paxton supercharged 312's. 312 HP. They were faster than the hot 283's.

Another interesting point is that this thing can be used in virtually any application where gear reduction is needed, as it scales extremely well. >> Here's a _very_ interesting concept: >> http://www.fallbrooktech.com:80/NuVinci.asp [quoted text clipped - 4 lines] > simpler than that that it replaces.
