Abstract:
A device for operating a shifting element of a drive mechanism, having a piston positioned in a piston space to slide between first and second end positions. The piston is operated hydraulically and depends on the hydraulic pressure in the piston space and a force of a resetting mechanism acting on the piston, which opposes the activating force that is equivalent to the hydraulic pressure in the piston space. The transmission capacity of the shifting element is reduced by a force acting on the piston in the direction of the first end position and is increased by a force acting on the piston in the direction of its second end position. The piston is held by a mechanical holder against a force acting on the piston in the direction of the first end position in at least one preset position which is different from the first end position.
