Patent ID: 8601891

Claim:
A driving device comprising: a housing tube connectable to one of a stationary base part and a movable structural component part; a protective tube connectable to the other of the stationary base part and the movable structural component part; a spindle drive by which the housing tube and protective tube are movable axially relative to one another, comprising: a threaded spindle: and a spindle nut arranged on the threaded spindle; a rotary drive that drives the spindle drive in rotation via an overload protection device, a rotationally rigid interconnection of the overload protection device configured to be canceled when a determined torque is exceeded; a sensor element arranged so as to be stationary with respect to the housing tube; and a magnetic ring having a plurality of north poles and south poles arranged to be rotationally movable near the sensor element, the magnetic ring cooperating with the sensor element, wherein the magnetic ring is arranged at a part of the overload protection device that is connected to the threaded spindle to be fixed with respect to rotation relative to the threaded spindle.
