摘要:
A dual clutch transmission for a motor vehicle, having a dual clutch with two start up clutches which, via a prime mover, can be respectively connected with one of first and second transmission input shafts arranged coaxially in relation to each other, such that a group of gears is allocated to each of the transmission input shafts. To minimize the size of the transmission, the gear groups are constructed as sub-transmissions that are mounted laterally with respect to the dual clutch. Each gear group has a counter shaft and a main shaft, with the main shaft being a transmission output shaft. Each sub-transmission has a single sub-transmission connection that transmits drive from the associated transmission input shaft to the counter shaft of the sub-transmission.

摘要:
A split power transmission with a variable drive, a brake, a clutch, an integrating transmission containing a planetary set, the internal gear forming the output of the transmission, and an additional planetary set located between the drive shaft and the transmission. A portion of the transmission drive shaft power is transferable to the transmission which includes a secondary shaft located axially parallel to the variable drive. The power of the variable drive is directed towards the integrating transmission via the secondary shaft by using a defined transmission ratio. Torque division in the low cruising range and is achieved by locking the brake connecting the internal gear of the planetary set located between the drive shaft, and the transmission to the unit. Whereas in the high cruising range, by engaging the clutch the sun gear of the transmission is interlocked with the internal gear of the transmission.
