Abstract: A multi-group transmission of a vehicle having a motor connected to an input shaft of the transmission, via a starting element, and the transmission comprises a splitter group, a main group and a main transmission shaft, on the drive output side. A powershift unit can couple the input shaft to the main transmission shaft for engaging an intermediate gear during a gearshift. The powershift unit and a shifting device for engaging gear constants of the splitter group are an integrated unit. During operating the transmission, with the starting element at least partly engaged during intermediate gear engagement, the powershift unit operates in a slipping mode and supports torque of the motor at the main transmission shaft while rotation of the motor is synchronized with a target gear. After which, an original gear is disengaged while free from load, the target gear is engaged when synchronized, and the intermediate gear is again disengaged.

Abstract: A motor vehicle transmission having at least two transmission groups and a method for operation of the transmission in which a mechanism is provided for maintaining traction force during gearshifts. A first friction clutch is an intermediate-gear clutch connected to a driveshaft of the motor and to a main transmission shaft which is connected with a transmission output shaft, the second friction clutch is a change-under-load clutch connected to the driveshaft and to a loose wheel of a second gear constant of a splitter group, and the third friction clutch is a change-under-load clutch connected with the driveshaft and with a loose wheel of a first gear constant of the splitter group. A direct connection can be formed in the transmission between the driveshaft and the main transmission shaft by way of the intermediate-gear clutch and the gear constants of the splitter group can be shifted, under load, by the change-under-load clutches.

Abstract: A multi-group transmission of a vehicle is arranged in a drivetrain and includes traction force support during gearshift operations. A clutch mechanism, including a frictional clutch and two shifting clutches is arranged between a drive motor with a driveshaft and a transmission input shaft, such that the driveshaft can be connected to the transmission input shaft by one shifting clutch in a first shift position in combination with the frictional clutch or in a second shift position with bridging of the frictional clutch, such that the driveshaft can be directly connected to a main transmission shaft by the other shifting clutch in a shift position in active combination with the frictional clutch. In a method for operating the transmission, the frictional clutch is controlled and operated in combination with the first shifting clutch as a starting clutch and with the second shifting clutch as an intermediate-gear clutch.

Abstract: A transmission of a vehicle and a method for its operation. The transmission has a range group arranged downstream from a main group. The main group output couples a sun gear and a transmission output to a planetary gear carrier of the range group, with a starting element and a change-under-load device, which is integrated in the range group for engaging a traction-force-supporting direct intermediate gear during a gearshift, to connect the transmission input and output shafts. An input component of the change-under-load device is connected to the transmission input shaft and an output component of the change-under-load device is connected to the planetary gear carrier. To increase the efficiency of drive during gearshifts at least one change-under-load device is provided for engaging at least one gear of the main group and/or at least one constant positioned upstream from the main group, which enables shifting under at least partial load.

Abstract: A motor vehicle transmission and method of its operation. The transmission has at least two transmission groups including a way of maintaining traction force during gearshifting operations. Two change-under-load clutches and an intermediate-gear clutch enable traction-force-maintaining gearshifts to be carried out on a splitter group. The first change-under-load clutch has an input connected to a drive motor and an output side to a loose wheel of a first gear constant, the second change-under-load clutch has an input connected to the motor and an output to a loose wheel of the second gear constant. The intermediate-gear clutch has an input connected to the loose wheel of the second gear constant and an output to a shaft of the main group, such that a direct gear can be engaged as an intermediate gear, and the gear constants can be shifted under load by the first and second change-under-load clutches.

Abstract: A multi-group transmission of a motor vehicle which includes at least two transmission groups arranged in a drivetrain and a way for supporting traction force during gearshifts such that traction-force gearshifts are maintained with improved shifting comfort at comparatively low cost, little design effort and compact installation space demands. At least one electromagnetic clutch is a change-under-load unit by which, bypassing the force flow of at least one main group made as a gear-change transmission, an active connection can be formed between a driveshaft and a main transmission shaft or a transmission output shaft. During a gearshift operation, an active connection is temporarily made between a driveshaft and a main transmission shaft or a transmission output shaft by way of at least one electromagnetic clutch designed as a change-under-load unit.

Abstract: The invention relates to a multi-group transmission of a motor vehicle with at least two transmission groups (2, 3) arranged in a drive train, in which the means for switching an intermediate gear are provided, in order to diminish or avoid interruptions in tractive force during gear changes. A planetary transmission (41) is arranged between a first transmission group (2) and a second transmission group (3), in order to enable gear changes without interruptions in tractive force with a variably selectable intermediate gear, as well as efficient operation that involves as little wear as possible, whereby a transmission input shaft (17) can be brought into a functional connection with a transmission main shaft (30) via the planetary transmission (41).
