Patent ID: 6869380

Claim:
A driveline for a mobile vehicle having one planetary transmission ( 7 ) in which a rotatable part of the planetary transmission ( 12 ) is connectable, via a multi-disc brake ( 14 ), with a non-rotatable housing ( 4 ), wherein the multi-disc brake ( 14 ) is activatable in a closing direction by a piston which moves in an axial direction against tension of a spring ( 20 ), an automatic resetting device limits movement of a piston stroke of the piston when the multi-disc brake ( 14 ) is actuated in an opening direction, and the automatic resetting device has at least one clamping element ( 22 ) which is situated in a hole ( 40 ) of the piston ( 18 ) and transmits axial force of the at least one clamping element ( 22 ) to a washer ( 23 ) which is displaceable along a defined path between first and second stops.
