Abstract
A clutch arrangement is formed with drive-side and, output-side clutch elements and a clutch piston for operative connection and disengagement between the drive-side and output-side clutch elements. Associated with at least two clutch elements is an elastically deformable clutch element working mechanism through which the corresponding clutch elements can be acted upon in direction away from one another by an axial force to assist disengagement of the drive-side and output-side clutch elements. The clutch element working mechanism provides a considerable change in the gradient of the axial force exerted on the clutch elements as a result of even a small change of shape of the clutch element working mechanism so that a sharply rising axial force of the clutch element working mechanism works against the clutch piston.
