Patent ID: 7437964

Claim:
A double clutch transmission with an input shaft ( 10 ) and an output shaft ( 20 ) and two intermediate shafts ( 12 , 14 ) arranged in a transmission housing ( 95 ) coaxially with the transmission input and output shafts ( 10 , 20 ) and two clutches (K 1 , K 2 ), each connected to one of inner and outer intermediate shafts ( 12 , 14 ), the transmission output shaft ( 20 ) being supported by means of a rolling bearing arrangement ( 97 and 96 or 85 or 90 ), the rolling bearing arrangement ( 97 and 96 or 85 or 90 ) comprising two tapered-roller bearings ( 97 and 96 or 85 or 90 ), the inner intermediate shaft ( 12 ) being arranged inside the outer intermediate shaft ( 14 ) which is a hollow shaft, the rolling bearing arrangement comprising a third rolling bearing ( 85 ) and a fourth rolling bearing ( 90 ) , the rolling bearing arrangement ( 97 and 96 or 85 or 90 ) being preloaded and the third rolling bearing ( 85 ) and the fourth rolling bearing ( 90 ) being in an X arrangement in relation to the rolling bearing ( 97 ) which supports the transmission output shaft ( 20 ) in the transmission housing ( 95 ), the rolling bearing ( 96 ) which supports the transmission output shaft ( 20 ) in relation to the radially inner intermediate shaft ( 12 ) being arranged radially inside, and extending axially into, a gearwheel ( 48 ) of the inner intermediate shaft ( 12 ) which gearwheel ( 48 ) belongs to a first gear constant (C 1 ) and is also connected to the inner intermediate shaft ( 12 ) is supported by the third roller bearing ( 85 ) within the hollow gearwheel ( 66 ) of the outer intermediate shaft ( 14 ) which hollow gearwheel ( 66 ) belongs to a second gear constant (C 2 ) of the double clutch transmission.
