Abstract (en)

[origin: EP2226453A2] The drive has a driving motor (2), and a spindle-spindle nut transmission (3) provided downstream to the driving motor for production of linear drive movements and comprising two connections (4, 5) for recovery of drive movements. An integral helical compression spring aligned to a spindle longitudinal axis is provided for pre-stressing the drive in a withdrawn position. The helical compression spring has spring coils of different diameters for adjustment of the helical compression spring at geometrical conditions.
