A hydraulic assembly for actuating a setting unit in a motor vehicle may include at least one hydraulic actuating unit which acts on the setting unit, as well as at least one piston pump with a piston which is displaceably positioned in a housing, wherein, when the piston moves, there is built up a hydraulic pressure for loading the actuating unit. There is provided a driveshaft with an axis of rotation and an eccentric, wherein the eccentric acts on the piston of the at least one piston pump and, when the driveshaft rotates, builds up a hydraulic pressure. Furthermore, the hydraulic assembly may be integrated within a coupling assembly.
