DUAL CLUTCH TRANSMISSION AND HYBRIDIZED DRIVE TRAIN HAVING A DUAL CLUTCH TRANSMISSION

摘要

The invention relates to a dual clutch transmission (11, 211, 411, 611), comprising a gear-change transmission (15, 215, 415, 615) for forming eight gear steps having two countershafts (29, 31, 229, 231, 429, 431, 629, 631, 829) and having a common output shaft (33, 233, 433, 633). Said dual clutch transmission is configured in such a way that all gear steps are designed as forward gears. Hereby, a double clutch (13, 213, 413,613) has two clutch packs (17, 19, 219, 417, 419, 617, 619) arranged on a central axis (23, 223, 423, 623) of the double clutch transmission. A drive input shaft (21, 221, 421, 621) of the dual clutch transmission is seated on the central axis (23, 223, 423, 623), on which drive gearwheels (41, 241, 441, 641; 43, 243, 443, 643; 45, 245, 445, 643; 47, 247, 447, 647; 49, 249, 449, 649; 51, 251, 451, 651) of the individual gear steps are seated.
