Abstract
A double clutch winding transmission, having two sub-transmissions (T1, T2), coaxial transmission input shafts (1, 19), which are each coupled to a clutch (K1, K2), at least one counter shaft (2, 22) and a transmission output shaft (15) that is coaxially aligned with the transmission input shaft (1, 19). In at least one gear shift position, the flow of energy (L1 to L8) in the transmission winds through at least two meshing gear wheels (3 to 14), forming gear wheel levels (Z1 to Z6). The two sub-transmissions (T1, T2) are configured as two, consecutively positioned, single winding transmissions (W1, W2), each having at least four forward gear positions.

A double clutch winding transmission comprising first and second sub-transmissions (T1, T2), a clutch (K1, K2), at least one counter shaft (2, 22) and a transmission output shaft (15), the first sub-transmission (T1) has a transmission input shaft (19) that is coaxially aligned with a transmission input shaft (1) of the second sub-transmission (T2) and the transmission output shaft (15), the transmission input shafts (1, 19) of the first and second sub-transmissions (T1, T2) are each coupled to the clutch (K1, K2), such that a flow of energy (L1, L2, L3, L4, L5, L6, L7, L8) of at least one gear shift position is passed through at least two, meshing gear wheels (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14), forming gear wheel levels (Z1, Z2, Z3, Z4, Z5, Z6), the first and the second sub-transmissions (T1, T2) are two single winding transmissions (W1, W2) that are positioned one behind an another in the double clutch winding transmission and comprise at least four forward gear shift positions.
