The invention relates to a bearing arrangement of the transmission shafts of a twin-clutch transmission ( 1 ) which has a central first input shaft (W 1 ) connected at the engine-side with a first clutch (K 1 ) of the twin-clutch arrangement, a shorter second input shaft (W 2 ) designed as a hollow shaft which is co-axially disposed on the first input shaft (W 1 ) and is connected with a second clutch (K 2 ) of the twin-clutch arrangement and a main shaft (W 3 ) arranged parallel to the two input shafts (W 1 , W 2 ) and can be selectively connected by way of a plurality of gear wheel stages each of which comprises one fixed wheel and one loose wheel, and a shift clutch coordinated with the respective loose wheel can be connected with the first input shaft (W 1 ) and the second input shaft (W 2 ) and the drive constant (K) formed by two fixed wheels is connected with an output shaft (W 4 ) disposed parallel to the main shaft (W 3 ), wherein each of the two input shafts (W 1 , W 2 ) is coordinated with a plurality of toothed gearwheels, wherein the loose wheels of adjacent gear wheel stages are disposed by pairs on a common transmission shaft and can be alternatively shifted by two shift clutches combined in one shift set and wherein the drive constant (K) is situated in the area of the transmission-inner end of the second input shaft (W 2 ) between two pairs of toothed gear wheels. For optimal bearing arrangement of the transmission shafts (W 1 , W 2 , W 3 ) there is provided a bearing plane ( 27 ) formed by an inner wall ( 23 ) of the transmission housing and lying axially adjacent to the drive constant (K), there being situated in one bearing (L 3.3 ) of the main shaft (W 3 ) in the housing wall ( 23 ), one bearing (L 1.3 ) of the first input shaft (W 1 ) in the second input shaft (W 2 ) and one bearing (L 2.3 ) of the second input shaft (W 2 ) in the housing wall ( 23 ).
