An electromechanical linear drive having a housing and having at least one piston rod that passes through an end-located housing cover, projects at one end out of the housing, and is carried by a spindle nut arranged longitudinally displaceably in a housing interior space, the spindle nut sitting on a threaded spindle that extends through the housing interior space and can have a rotary motion imparted to it by means of an electric motor, and is displaceable back and forth in the housing interior space as a result of the rotary motion of the threaded spindle, is characterized in that a lubrication nipple (22) accessible on the outer side of the housing (11), and at least one lubrication passage (23, 24) joined to said nipple (22) and opening into a stop surface (21), located in the housing interior space (31), for the spindle nut (18), are arranged in a housing region (14) constituting an end stop for the motion of the spindle nut (18); and at least one lubrication conduit (25) leading to the lubrication sites of the spindle nut (18) is arranged in the spindle nut (18) in such a way that when the spindle nut (18) is in abutment against the stop surface (21) of the housing (11), the lubrication conduit is joined to the housing-side lubrication passage (23, 24). |
