Patent ID: 8070649

Claim:
A dual clutch automatic transmission comprising, in combination, a input clutch having an input adapted to be driven by an engine and an output, an electric motor coupled to said output of said input clutch, a pair of clutches having inputs coupled to said electric motor and having a first clutch output and a second clutch output, a first countershaft and a second countershaft spaced from and parallel to said first countershaft a first gear coupled to said first clutch output and in constant mesh with a first input gear disposed on said first countershaft and a second input gear disposed on said second countershaft, a second gear coupled to said second clutch output and in constant mesh with a third input gear disposed on said first countershaft and a fourth input gear disposed on said second countershaft, a first synchronizer clutch assembly disposed on said first countershaft between said first and said third input gears for selectively connecting said gears to said first countershaft, a second synchronizer clutch assembly disposed on said second countershaft between said second and said fourth input gears for selectively connecting said gears to said second countershaft, a first output gear disposed on said first countershaft and in constant mesh with a first differential input gear, a second output gear disposed on said second countershaft and in constant mesh with said first differential input gear, a third output gear disposed on said first countershaft and in constant mesh with a second differential input gear, a fourth output gear disposed on said second countershaft and in constant mesh with a said second differential input gear, a third synchronizer clutch assembly disposed on said first countershaft between said first and said third output gears for selectively connecting said gears to said first countershaft, a fourth synchronizer clutch assembly disposed on said second countershaft between said second and said fourth output gears for selectively connecting said gears to said second countershaft, and a differential assembly driven by said first and said second differential gears and having a pair of coaxial outputs.
