Transmission for a motor vehicle

A transmission for a motor vehicle, the transmission comprising at least two sub-transmissions, each of the at least two sub-transmissions having at least one input shaft and an output shaft being arranged as a drive output shaft of both the at least two sub-transmissions, the input shafts being arranged on an input shaft axis and the drive output shaft being arranged either on the input shaft axis or on a countershaft axis that is parallel to the input shaft axis, and an intermediate gear system having at least one countershaft, the at least one countershaft being arranged on the countershaft axis, and at least four shifting elements being provided, at least two of the shifting elements being arranged on the input shaft axis and at least two of the shifting elements being arranged on the countershaft axis, and one of the input shafts being connectable to the drive output shaft by way of at least one of at least two wheel planes and at least one of the shifting elements at least two of the at least four shifting elements are unsynchronized shifting elements and at least two of the at least four shifting elements are synchronized shifting elements, and at least one of each of the synchronized and the unsynchronized shifting elements is arranged on the input shaft axis, and

• one of the synchronized shifting elements and one of the unsynchronized shifting elements are combined to form a shifting assembly which is actuated by a common shifting element actuating device.

A dual clutch transmission for a motor vehicle, the dual clutch transmission comprising:

• first and second sub-transmissions, the first sub-transmission having an input shaft and the second sub-transmission having an input shaft, and the input shafts of the first and the second sub-transmissions being coaxially aligned along an input shaft axis;
• a drive output shaft being drivably connectable to the first and the second sub-transmissions and forming a transmission drive output, the drive output shaft being axially aligned along the input shaft axis;
• an intermediate gear system comprising at least one countershaft being aligned along a countershaft axis extending parallel to the input shaft axis;
• first, second, third, fourth, fifth and sixth shifting elements, the first, the second and the third shifting elements being arranged along the input shaft axis and the fifth and the sixth shifting elements being arranged along the countershaft axis;
• first, second, third, fourth and fifth wheel planes being selectively engagable to connect to the input shafts of the first and the second sub-transmissions to the drive output shaft and obtain a plurality of gear ratios;
• one of the input shafts of the first and the second sub-transmissions being connectable to the drive output shaft via at least one of:
• engagement of at least two of the first, the second, the third, the fourth and the fifth wheel planes, and
• engagement of at least one of the first, the second, the third, the fourth, the fifth and the sixth shifting elements;
• the first, the second, the third and the fourth shifting elements being aligned along the input shaft axis, and the first, the second and the fourth shifting elements being unsynchronized shifting elements and the third shifting element being a synchronized shifting element;
• the fifth and the sixth shifting elements being aligned along the countershaft shaft axis, and the fifth and the sixth shifting elements being synchronized shifting elements;
• and
• the third and the fourth shifting elements form a shifting assembly and are actuated by a common shifting element actuating device.
