" From: Mark Price <markprice242@xxxxxxxxxxxx> " " Someone and I can't remember who, was it White?, made a variable transmission back in the 1910's that was a large heavy flywheel mounted to an engine and the way the car was driven was the engine speed was a constant and you moved a lever which moved the drive along the face of the flywheel. Starting close to center for low speed and torque moving out toward the edge as speed increased. " I remember reading the artice that stated the things had so much torque you could put a front tire against a tree and the car would climb it vertically! " What I can't remember is the specifics of how it was made and worked nor who made the thing! I know I remember it was never mass produced. I assume it was due to a lack of reliabilty. -probably- the driven disk slid along a splined shaft which took the power out. related schemes have been tried in recent decades; the most interesting looked a little like a torque converter. imagine a bagel, split in half and hollowed out. now imagine two wheels inside it on a horizontal shaft crossing the middle, but free to roll independently. the front half of the bagel turns, the wheels roll, and the back half of the bagel turns the other way. now imagine the shaft the wheels are on is two shafts, one for each, and they are mounted in vertical yokes that can pivot like u-joints. pivoting the wheels has to be coordinated, but toe them in and they roll in the inner edge of the front bagel half and the outer edge of the rear bagel half, producing speed reduction. toe them out and you get speed multiplication. the problem is that you have to make them extremely precisely and from very hard materials to be efficient [because what you have is very much like a ball bearing] so that you can run very high contact pressures because slippage is death. monsanto even developed a special lubricant that turns solid under extreme pressure [santotrac iirc] but apparently the technology wasn't there yet or we'd all be driving them. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
