Abstract:
A continuously variable transmission comprising:an input shaft;an intermediate shaft;an output shaft;a variable ratio drive mechanism having an input, and an output driveably connected to the input and intermediate shaft, for producing a continuously variable ratio of the speed of the input to the speed of the output;a fixed ratio drive mechanism having a first element, and a second element driveably connected to the first element and intermediate shaft;a first gearset driveably connected to the input shaft, output shaft and first element;a transfer clutch for selectively driveably connecting and disconnecting the input of the variable ratio drive mechanism and input shaft; anda low brake alternately holding against rotation and releasing an element of the first gearset, whereby the output shaft is driven at a slower speed than the speed of the input shaft when the low brake is engaged.
