Patent ID: 8001863

Claim:
A bearing arrangement of transmission shafts of a twin-clutch transmission ( 1 ) which has a central first input shaft (W 1 ) connected at an engine side with a first clutch (K 1 ) of a twin-clutch arrangement, a shorter second input shaft (W 2 ), designed as a hollow shaft, being co-axially disposed on the first input shaft (W 1 ) and being connected with a second clutch (K 2 ) of the twin-clutch arrangement and a main shaft (W 3 ) arranged parallel to the first and the second input shafts (W 1 , W 2 ) and being connectable, via a plurality of gear wheel stages, each comprising a fixed gear wheel and a loose gear wheel and, by way of a shift clutch, coordinated with a respective loose wheel being selectively connectable with the first input shaft (W 1 ) and the second input shaft (W 2 ) and one drive constant (K) and being connected with an output shaft (W 4 ) disposed parallel to the main shaft (W 3 ), each of the first and the second input shafts (W 1 , W 2 ) having several toothed gear wheels, loose gear wheels of adjacent gear wheel stages are each located by pairs on a common transmission shaft and being alternatively shiftable by two shift clutches, combined in one shift set, and the drive constant (K) being disposed in an area of a transmission-inner end of the second input shaft (W 2 ) between two pairs of toothed gear wheels, a bearing plane ( 27 ) formed by an inner housing wall ( 23 ) of a transmission housing being provided and being axially adjacent to the drive constant (K), aligned along the bearing plane ( 27 ) in the inner housing wall ( 23 ) are a bearing (L 3 . 3 ) of the main shaft (W 3 ), a bearing (L 2 . 3 ) of the second input shaft (W 2 ), and a bearing (L 1 . 3 ) of the first input shaft (W 1 ) being arranged within the second input shaft (W 2 ) and along the bearing plane ( 27 ).
