Abstract
A dual clutch transmission includes a pair of concentric clutches which selectively drive a pair of concentric drive shafts, pairs of gears in constant mesh, a first portion of which are associated with the first drive shaft and a first, parallel countershaft and a second portion of which are associated with the second drive shaft and a second, parallel countershaft. Synchronizer clutches disposed adjacent the gears on the countershafts selectively connect the gears to the countershafts. Both countershafts drive a single output shaft through transfer gears. The output shaft is coupled to a drive (input) pulley of a continuously variable final drive assembly which receives a chain which drives a driven (output) pulley which is coupled to and drives the cage of a differential assembly. A pair of axles are driven by the side gears of the differential and, in turn, drive the vehicle wheel.
