Abstract

A dual clutch transmission for a motor vehicle including two sub-transmissions, each having at least one input shaft. An output shaft outputs drive from both sub-transmissions. The input shafts are arranged on an input shaft axis and the output shaft is arranged on the input shaft axis or a parallel countershaft axis. An intermediate gear system includes at least one countershaft which is arranged on the countershaft axis. At least four shifting elements are arranged such that, in each case, at least two shifting elements are arranged on the input shaft axis and on the countershaft axis. At least one input shaft can be connected to the output shaft by way of two wheel planes and/or at least one shifting element. Preferably half of the shifting elements are unsynchronized and at least one-third of the shifting elements are synchronized. Also a method for operating a dual clutch transmission.
