Patent number: 8567273Abstract: A dual clutch transmission having improved packaging and reduced spin losses provides a five, six or seven forward speeds and reverse. An input shaft includes two or three gears which are in constant mesh with and directly drive associated gears freely disposed on a pair of parallel quills. Synchronizer clutches associated with these driven gears selectively synchronize and connect the gears to the quills which are, in turn, connected to countershafts residing within the quills. Additional gears which are in constant mesh with a pair of ring (output) gears are synchronized and connected to the countershafts by additional synchronizer clutches. Activation of two synchronizer clutches and one input clutch provides a selected gear ratio and transfers torque from the input shaft to the output ring gears.Type: GrantFiled: June 14, 2010Date of Patent: October 29, 2013Assignee: GM Global Technology Operations LLCInventors: Edward W. Mellet, James B. Borgerson
