Abstract: Methods for assembling motor vehicle modules that include a shaft, a functional element, and a housing part are disclosed. The shaft may be arranged rotatably in bearing receptacles of the housing part, and the functional element may be fastened by a hub opening on a thickened portion of the shaft. The functional element may first be inserted into the housing part, wherein the shaft can then be pushed in by way of a temperature difference. During the pushing-in of the shaft, the functional element may not yet be in its final axial position and may not yet have its final orientation with respect to the angle of rotation, wherein the positionally correct positioning of the functional element may subsequently take place by way of press compaction. Before the shaft is inserted into the housing part, at least one of the bearing receptacles may be formed in such a manner that a rolling bearing is inserted, in particular pressed, in a receiving opening of the housing part.

Abstract: An actuator for an electrohydraulic gas exchange valve train of a combustion engine is provided. The actuator has an actuator housing which can be mounted on the combustion engine with a borehole, a hydraulic piston, which is mounted therein such that it can carry out a reciprocating movement, for actuating the gas exchange valve and an axial stop which, when the actuator housing is in the unmounted state relative to the combustion engine, limits the piston stroke out of the borehole to a mounting stroke (T). This mounting stroke is smaller than a maximum operating stroke (L) with which the hydraulic piston actuates the gas exchange valve, the piston stroke being only temporarily limited to the mounting stroke by the axial stop and no longer being limited to the mounting stroke once the actuator is in operation.
