Drive device
First Claim
1. A drive device comprising:
- a first fastening device (15) connectable to one of a stationary base part and to a movable part;
a second fastening device (24) connectable to one of the movable part and to the stationary base part;
a spindle drive (17) comprising a threaded spindle (16) and a spindle nut (19) mounted on said threaded spindle (16) for moving said first and the second fastening devices (15, 24) axially relative to each other; and
a rotary drive (9) for rotating said spindle drive (17) by way of an overload safety device including a nonrotatable connection between two components which can be released when a predetermined torque is exceeded;
said overload safety device being formed by a clutch device (15) comprising an inner part (32);
a damping element (33);
an intermediate part (34) and an outer part 36;
said inner part (32) connected to said rotary drive (9), said inner part rotating said intermediate part (34) by way of said damping element (33) and, by way of said intermediate part (34), rotating said outer part (36) connected to said spindle drive (17).

Abstract
A drive device includes a first fastening device (5), for connection to a stationary base part, especially a vehicle body, or to a movable part, especially a vehicle (hinged) lid or door; a second fastening device (24), for connection to the movable part or to the stationary base part; a spindle drive (17), which includes a threaded spindle (16) and a spindle nut (19) mounted on the threaded spindle (16) and capable of moving the first and the second fastening devices (5, 24) axially relative to each other; and a rotary drive (9), which rotates the spindle drive (17) by way of an overload safety device, wherein the nonrotatable connection between the two components can be released when a certain torque is exceeded, and wherein the overload safety device is formed by a clutch device (15), which comprises an inner part (32) connected to the rotary drive (9), which inner part rotates an intermediate part (34) by way of a damping element (33) and, by way of the intermediate part (34), rotates an outer part (36) connected to the spindle drive (17).
