TWIN CLUTCH TRANSMISSION FOR A MOTOR VEHICLE
The invention relates to a twin clutch transmission (1) for a motor vehicle. This twin clutch transmission (1) has two input shafts (2, 3), two clutches (K1, K2) and at least one first and one second driving shaft (4, 5). The first input shaft (2) can be actively connected to the first clutch (K1), and the second input shaft (3) can be actively connected to the second clutch (K2). The first driving shaft (4) is situated underneath the input shafts (2, 3) and the second driving shaft (5) is situated above the input shafts (2, 3) (or reversed). The input shafts (2, 3) and driving shafts (4, 5) comprise intermeshing gear wheels, and at least two gear wheels (Z1 to Z18) form a gear step. At least one gear wheel of a gear step is provided in the form of an engageable and/or disengageable idler gear, and the other gear wheel is preferably provided in the form of a fixed gear. Each driving shaft (4, 5) has a driving gear wheel (19, 20) for transferring rotatory force to the axle drive (21). Another shaft is provided for realizing the reverse gear RG. The aim of the invention is to realize a versatile highly designed and compact transmission. To this end, the additional shaft is provided in the form of a third driving shaft (22), this third driving shaft (22) has a drive gear wheel (23) for transferring rotatory force to the axle drive (21), and the drive gear wheels (19, 20, 23) of the driving shafts (4, 5) engage with an axle drive gear (21a) of the axle drive (21).
