Abstract
A driving device with a first and second fastening device which can be connected to a stationary base part, particularly a vehicle body, or can be connected to a movable structural component part, particularly a hatch or door of a vehicle, a spindle drive which has a threaded spindle and a spindle nut arranged on the threaded spindle and by which the first fastening device and the second fastening device are movable axially relative to one another, and a rotary drive which drives the spindle drive in rotation by an overload protection device, and the rotationally rigid connection thereof can be canceled when a determined torque is exceeded. The overload protection device is a ring element arranged on a driveshaft of the rotary drive.
Claims9
A driving device comprising:
- a first fastening device connectable to one of a stationary base part of a vehicle body and a movable structural component part of the vehicle;
- a second fastening device connectable to the other of the stationary base part of the vehicle body and the movable structural component part of the vehicle;
- a spindle drive comprising
- a threaded spindle;
- and
- a spindle nut arranged on the threaded spindle configured to move the first fastening device and the second fastening device axially relative to one another;
- a rotary drive having a driveshaft configured to drive the spindle drive in rotation, a portion of the driveshaft projects into an adapter sleeve coupled to the threaded spindle;
- and
- an overload protection device comprising a ring element arranged on the driveshaft of the rotary drive configured to couple the rotary drive and the spindle drive, the overload protection device further configured to cancel a rotationally rigid connection between the rotary drive and the spindle drive when a predetermined torque is exceeded.
