摘要： A transmission includes a transmission housing, a dual clutch assembly, a first through seven gear sets, a first transmission input shaft member rotatably supported in the transmission housing, a second transmission input shaft member rotatably supported in the transmission housing, a first countershaft rotatably supported within the transmission housing and spaced apart from and parallel with the first and second transmission input shaft members, a second countershaft rotatably supported within the transmission housing and spaced apart from and parallel with the first and second transmission input shaft members and five synchronizer assemblies each for selectively coupling at least one of the gears of the gear sets with at least one of the first countershaft and the second countershaft. The dual clutch assembly and the synchronizer assemblies are operable to achieve at least eight forward speed ratios and a reverse speed ratio between an input member and output member.

摘要： An eight forward speed dual clutch transmission includes a pair of input clutches which selectively provide drive torque to a pair of concentric input shafts. Gears coupled to and driven by the input shafts are in constant mesh with gears freely rotatably disposed on a pair of parallel countershafts or layshafts. A plurality of synchronizer clutches selectively synchronize and connect the various gears to the countershafts or layshafts to provide a desired gear ratio in the proper sequence. Reverse gear is similarly provided through a three gear gear train. Upon the synchronization and engagement of a particular gear, the associated input clutch is activated or engaged to supply drive torque to the input shaft, through the synchronized and engaged gear pair and out the countershaft or layshaft. An additional gear on each countershaft or layshaft engages a common gear that directly drives a differential which, in turn, drives a pair of drive axles.
