Abstract

This invention relates to a pivot-hung door drive system with an electro-mechanical device that supplies the closing moment required for the opening and closing of the door, comprising a transmission which varies its translation ratio over the angle of rotation of the door, a guide that is connected with an output shaft and a driver roller that can execute a translation movement relative to the guide and in the guide, which driver roller is connected with a pinion that is engaged with a toothed rack that is connected with the spring system, whereby the axis of rotation of the output shaft is at a defined distance from the axis of rotation of the pinion, and the axis of rotation of the driver roller is at a defined distance from the axis of rotation of the pinion, such that when the output shaft and pinion are rotated, the translation ratio changes as a result of the changing axial distance between the output shaft and the driver roller.
