Six-speed double-clutch transmission

摘要

A six-speed double-clutch transmission comprises a driven double clutch (20), one clutch (K1) of which drives a first gear set (24/28) via a first input shaft (24) and the other clutch (K2) of which drives a second gear set (33/35) via a second input shaft (11) concentric to the first input shaft (24). One gear (25, 33) of each gear set (25/28, 33/35) is seated on an input shaft (11, 24), while the other gear (28, 35) is seated on a layshaft (13). An output shaft (12) and a predetermined number of further gear sets (42/41, 45/46, 48/49, 53/54) for the forward gears are furthermore provided. One gear (42, 45, 48, 53) of each of these gear sets is seated on the output shaft (12) and the other gear (41, 46, 49, 54) is seated on the layshaft (13). One of the forward gears is engaged by direct rotational connection of the input shaft (11) and the output shaft (12). Two different, adjacent forward gears are formed by means of the same further gear set. Four further gear sets are provided. The other three forward gears are each formed by one of the further gear sets (Fig. 1). <IMAGE>
