Claim:
A double clutch transmission ( 1 ), for a motor vehicle, comprising a transmission housing ( 13 ) in which a clutch chamber ( 2 ), for accommodating a double clutch ( 4 ), is filled with a clutch oil and a transmission chamber ( 3 ), for accommodating a double clutch transmission wheel set ( 5 ), is filled with transmission oil, first and second drive shafts ( 7 , 8 ), which are supported coaxially one inside the other whereby the first drive shaft ( 8 ) being configured as an interior central shaft emerging from the second drive shaft ( 7 ), which is configured as an exterior hollow shaft, at an end of the second drive shaft ( 7 ) inside the transmission chamber ( 3 ), and in which the first and the second drive shafts ( 7 , 8 ) being sealed by at least one sealing element to seal the clutch chamber ( 2 ) from the transmission chamber ( 3 ), a mounting component ( 12 ) being arranged inside the transmission housing ( 13 ) and fixed thereto for holding first and second adjacent sealing elements ( 19 , 20 ), the first sealing element ( 20 ) forms a seal radially on the hollow drive shaft ( 7 ) and the second sealing element ( 19 ) forms a seal radially on the central drive shaft ( 8 ), the first and the second sealing elements ( 19 , 20 ) being double sealing rings, each of which comprises two radial shaft, sealing rings ( 21 , 22 , 23 , 24 ), an intermediate area ( 29 ), which is connected to the clutch chamber ( 2 ), is formed between the double sealing rings ( 19 , 20 ) which, via an area of an interior radial shaft, the sealing rings ( 21 , 23 ) are supplied with the clutch oil for lubrication, and outside of the double sealing rings ( 19 , 20 ) an exterior area is formed which is connected to the transmission chamber ( 3 ), via exterior radial, shaft sealing rings ( 22 , 24 ), and supplied with the transmission oil for lubrication; wherein the mounting component ( 12 ), in addition to accommodating the sealing elements ( 19 , 20 ), also accommodates an intermediate wheel bearing for a reverse gear intermediate wheel ( 18 ).
