摘要
An electrical actuating drive for remote control of structural elements, for example windows, by means of a push rod which can be displaced longitudinally, comprises a motor (3) whose rotation direction can be reversed and which drives a worm gear shaft (8) via an epicyclic transmission (4 to 6), which worm gear shaft, for its part, engages with a worm gear (14), the worm gear being supported on a bearing carriage which can be displaced in the axial direction of the worm gear shaft (8) against the influence of compression springs (12). The side of the worm gear (14) opposite the worm gear shaft (8) engages with a rack (15) which represents the push rod for operating the structural element. The arrangement permits energy-destroying absorption of the flywheel energy of the motor (3) into the springs (12) when the rack (15) is blocked. IMAGE
