ABSTRACT:
A bearing system for coaxial input shafts of a twin-clutch transmission mounts the outer input shaft rotatably on the inner input shaft via at least two internal radial roller bearings which are mounted on the inner input shaft. The outer input shaft is secured in an axial direction thereof via two axial roller bearings which are effective in respective opposite directions. The inner input shaft is secured in an axial direction thereof and is rotatably mounted, via a fixed roller bearing, in an external housing wall on the engine-remote side of the transmission housing. The inner input shaft is mounted rotatably and displaceably in the axial direction in an internal housing wall of the transmission on the engine side via an external radial roller bearing which is mounted on the outer input shaft.
