Dual-clutch transmission for use in powertrain of e.g. commercial vehicle, has spur gear stage whose idle gears are arranged on input shaft and connectable with another input shaft in torque-proof manner over gear shift element

摘要

The transmission (1a) has spur gear stages (R3-R5) whose jackshaft-side gear wheels (Z3-Z5) are arranged on a sleeve shaft (HW), which is coaxially and rotatably arranged on a jackshaft (VW1) and torque-proofly connected with the jackshaft over a coupling shift element (SK). One of the spur gear stages forms an axial innermost spur gear stage of odd gears. Idle gears (Z15) of the spur gear stage are rotatably arranged on an input shaft (EW1) and connected with another input shaft (EW2) in a torque-proof manner over a supplementary gear shift element (S5asterisk). The input shafts are designed as sleeve shafts.
