Multi-group transmission of a motor vehicle

摘要

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.
