Abstract
A door drive for a motor vehicle door or motor vehicle flap, which is provided with an electromotive drive, a transmission downstream of the drive, and a force-transmission element. The force-transmission element is operatively connected to a leaf of the motor vehicle door or motor vehicle flap. An output element of the transmission and the force-transmission element are coupled by a toothing with compensation for play. According to the invention, the output element and/or the force-transmission element are not only designed to be moveable for play compensation, but can also be permanently fixed after the compensation for play.
