    摘要： An input brake assembly is provided for selectively grounding a transmission input member. The packaging location of the input brake assembly does not interfere with, and thus still allows the option of providing a bypass clutch for a flex plate-type flywheel connecting the engine with the transmission input member. The input brake assembly includes a flywheel, preferably a flex plate, for transferring rotary torque between the engine and the transmission input member and a ring gear secured to the outer periphery of the flex plate. A pinion gear is axially movable into and out of meshing engagement with the ring gear. A grounding device is operatively connected to the pinion gear and is operable to prevent rotation of the pinion gear, thereby braking the flex plate as well as the transmission input member operatively connected thereto when the pinion gear is in meshing engagement with the ring gear.

    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.
