ABSTRACT:
An automatic dual clutch transmission includes an input clutch which selectively connects a prime mover to an electric motor. The electric motor output, in turn, drives a pair of gears, one of which is in constant mesh with a first gear on a first quill and a second gear on a second quill, the other being in constant mesh with a third gear on the first quill and a fourth gear on the second quill. On each quill, between each pair of gears driven by the input is a pair of dog clutches which connect one of the two gears to the associated quill. Each of the quills drives an input of a respective pair of friction clutches which drive a respective pair of layshafts or countershafts. A similar arrangement of a second pair of gears flanked by dog clutches connects each layshaft or countershaft through one of a pair of gears which are in constant mesh with a pair of output gears coupled to and driving a differential cage.
