Patent ID: 7963191

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 and having an output shaft, a first drive gear and a second drive gear coupled to said output shaft, a first quill having a first input gear rotatably disposed thereon and in constant mesh with said first drive gear and a third input gear rotatably disposed thereon and in constant mesh with said second drive gear, a first dog clutch for connecting one of said first and third input gears to said first quill, a second quill having a second input gear rotatably disposed thereon and in constant mesh with first drive gear and a fourth input gear rotatably disposed thereon and in constant mesh with said second drive gear, a second dog clutch for connecting one of said second and fourth input gears to said second quill, a first countershaft disposed coaxially with said first quill and a first countershaft clutch for connecting said first quill and said first countershaft, a second countershaft disposed coaxially with said second quill and a second countershaft clutch for connecting said second quill and 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 dog clutch assembly disposed on said first countershaft between said first and said third output gears for selectively connecting said first and third output gears to said first countershaft, a fourth dog clutch assembly disposed on said second countershaft between said second and said fourth output gears for selectively connecting said second and said fourth output gears to said second countershaft, and a differential assembly driven by said first and said second differential input gears and having a pair of coaxial outputs.
