Transmission for a motor-vehicle

At least one of a passenger vehicle and a utility vehicle in combination with a dual clutch transmission for a motor vehicle, having at least two part-transmissions, each part-transmission comprising at least one input shaft (EW1, EW2),

• wherein an output shaft is arranged as the drive output shaft (AW) of both of the at least two part-transmissions,
• the at least one input shafts (EW1, EW2) is arranged on a main axis (2) and the drive output shaft (AW) is arranged either on the main axis (2) or on a secondary axis (3) which is parallel to the main axis (2),
• an intermediate transmission (4) having at least one countershaft (VW1, VW2, VW3) that is arranged on the secondary axis (3),
• at least one of the at least one input shafts (EW1, EW2) is connectable to the drive output shaft (AW) by at least one of:
• at least two gear planes (I, II, III, IV, V, VI), and
• at least one shifting element (S1, 32, S3, S4, S5, S6, S7, S8),
• at least first, second, and third shifting mechanisms (SE1, SE2, SE3, SE4) are provided, and at least the second shifting mechanism (SE2, SE3, SE4) is arranged on the main axis (2) and at least the first shifting mechanism (SE1) is arranged on the secondary axis (3) in such manner that a first gear plane is arranged directly between the first and the second shifting mechanisms and a second gear plane is arranged directly between the second and the third shifting mechanisms, and the first gear plane is arranged upstream from the second gear plane with respect to torque flow through the at least one input shafts to the drive output shaft.

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

• at least first and second part-transmissions, of the first part-transmission comprises an inner input shaft and the second part-transmissions comprises a hollow input shaft (EW1, EW2) which are both connectable to a common drive output shaft (AW) that outputs drive from the transmission;
• the first and the second input shafts (EW1, EW2) of the first and the second part-transmissions and the drive output shaft (AW) are coaxially aligned on a main axis (2), the first input shaft extends through the second input shaft;
• an intermediate transmission (4) comprises an inner countershaft and a hollow countershaft (VW1, VW2, VW3) that are coaxially aligned on a secondary axis (3) that is parallel to the main axis, the inner countershaft extends through the hollow countershaft;
• the inner and the hollow input shafts (EW1, EW2) of the first and the second part-transmissions are connectable to the drive output shaft (AW) by way of at least one of:
• at least two gear planes (I, II, III, IV, V, VI), and
• at least one shifting element (S, S2, S3, S4, S5, 56, S7, S8);
• a second and a third shifting mechanism (SE1, SE2, SE3, SE4) are coaxially aligned with the main axis (2) and a first shifting mechanism (SE1) is axially aligned with the secondary axis (3), such that, with respect to the main and the secondary axes, a first gear plane (II) is aligned directly between the first and the second shifting mechanisms and a second gear plane (III) is aligned directly between the second and the third shifting mechanisms, the first gear plane is arranged upstream from the second gear plane with respect to torque flow from the inner and the hollow input shafts to the drive output shaft.
