摘要

The releasing system has fixer on a clutch cover (2) and a release bearing (3) axially sliding on a guide bush (1) for operating a disk spring (5). A bell-crank lever unit is provided between the axially sliding release bearing and a fixed bearing (4) arranged on the guide bush at a distance from the release bearing. An axial pressurization of the release bearing is obtained for operating the disk spring by a Bowden cable engaging in a knee point (K) of the bell-crank lever unit.
