Double-clutch transmission unit with parking gear function has facility whereby during parking process the first input element and reverse input element are in engaged states at same time so that parking function is implemented

摘要

The double-clutch transmission unit, with a parking gear unit, has a number of input elements with a first input element (S1) which in an engaged state transmits torque to the gear train of a first shift stage, and a reverse input element (SR) which in the engaged state transmits torque to the gear train of the reverse gear train, wherein during a parking process the first input element and the reverse input element are in engaged states at the same time so that a parking function is implemented.
