Dual clutch transmission i.e. countershaft transmission, for front-transverse structure for drive train of motor car, has switching units directly rotationally rigidly connecting wheels of gear wheel planes with each other, respectively

摘要

The transmission has switching units (S7a, S8a) directly rotationally rigidly connecting loose wheels (Z22a, Z32a, Z53a) of gear wheel planes (Z2a, Z3a, Z5a) with each other, respectively. The loose wheels are arranged coaxial to a countershaft (14a). Input shafts (11a, 12a) are provided for attachment to load switching clutches (K1a, K2a). The countershafts are arranged offset parallel to the input shafts. The gear wheel planes and the switching units produce a connection between the input shafts and the countershafts.
