Vehicle drive train has closed coupling bell, inside which friction coupling is engageable and disengageable by central control

摘要

The vehicle drive train has a closed coupling bell (1), inside which a friction coupling (3) is engageable and disengageable by a central control (2). A flow wall (60) is arranged within the coupling bell. The flow wall has a central recess, inside which the central control (2) is arranged. The flow wall on its outer periphery has ribs (61a,61b), which are fixed to a housing wall of the coupling bell. An axially displaceable component of the central control is supportable on a friction coupling by means of a disengagement bearing. A bearing ring of the disengagement bearing has guide plates. The housing wall of the coupling bell on the inside is subjected to a surface-enlarging measure.
