Abstract
In a dual clutch transmission with a main group and final shift group, with a coupling device for coupling a transmission element of the main group to a final shift group transmission element of the final shift group, the transmission comprises two transmission gears (V4L, V5L, V1 H, V2H) which can be formed simultaneously with one of the transmission gears (V4L, V5L) assignable to a lower group of the final shift group and another of the transmission gears (V1H, V2H) assignable to an upper group of the final shift group.

A dual clutch transmission with a main group (10) and final shift rear-mounted group (11), with a coupling device (12) for coupling a main group transmission element of the main group (10) to a final shift group transmission element of the final shift group (11), said transmission comprising two transmission shift gears (V4L, V5L, V1H, V2H) with the same transmission ratio so that a power path can be established simultaneously via one of the transmission gears (V4L, V5L) of the main group (10) and another via one of the transmission gears (V1H, V2H) of the final shift group (11), the final shift group (11) comprising a planetary wheel transmission (14), and the final shift group transmission element being a planetary wheel carrier (15) of the planetary wheel transmission (14).
A method for a dual clutch transmission device with a main group (10) and a final shift rear-mounted group (11) and a coupling device (12) for coupling a main group transmission element of the main group (10) to a final shift group transmission element of the final shift group (11), said transmission comprising two transmission gears (V4L, V5L, V1H, V2H) which can be formed simultaneously with one of the transmission gears (V4L, V5L) assignable to a lower group of the final shift group (11) and another of the transmission gears (V1H, V2H) assignable to an upper group of the final shift group (11), with a main group transmission element of the main group (10) coupled to a final shift group transmission element fo the final shift group (11), the final shift group (11) comprising a planetary wheel transmission (14), and the final shift group transmission element being a planetary wheel carrier (15) of the planetary wheel transmission (14), said method comprising the step of:
- forming two transmission gears (V4L, V5L, V1HL, V2H) and assigning one of the transmission gears (V4L, V5L) to a lower group of the rear-mounted group (11) and one of the transmission gears (V1H, V2H) to an upper group of the rear-mounted group (11).
