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.

摘要： A transmission is disclosed having an input member, an output member, first, second and third planetary gear sets, a first interconnecting member, a second interconnecting member and six torque-transmitting mechanisms. The torque-transmitting mechanisms are selectively engageable in combinations of at least three to establish at least eight forward speed ratios and at least one reverse speed ratio between the input member and the output member. The planetary gear sets each have first, second and third members. The six torque-transmitting mechanisms are selectively engageable to interconnect one of the first, second, and third members with another of the first, second, and third members.
