ABSTRACT:
A continuously variable transmission and differential combination including an input shaft 36, a variable speed drive pulley 40 on the input shaft 36, a drive shaft 54, a variable speed driven pulley 500 on the driven shaft 54 and a v-belt 48 trained around the pulleys 40 and 50. A drive sprocket 64 driven by the drive shaft 54 and a driven sprocket 64 with a silent chain 66 trained around them provides a speed reduction drive. The driven sprocket 68 drives a sun gear 88 which drives planet gears 98 that mesh with a stationary ring gear 100. The planet carrier 102 is rotated at a reduced speed. The bevel gears 108 and 112 carried by the planet carrier 102 form a differential that drives axles 114 and 116. A reversing gear drive can be provided between the sun gear 78 and the sun gear 88 to reverse the direction of rotation of the axles 114 and 116.
