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.

An apparatus comprises a base plate configured to be coupled to a door, the door configured to be positioned in an open position and a closed position; a closing mechanism coupled to the base plate and configured to be coupled to a hinge of the door and having an unprimed state and a primed state, the closing mechanism configured to be transitioned between the unprimed state and the primed state by a user; wherein in the unprimed state the closing mechanism is decoupled from operation of the door; and in the primed state the closing mechanism is configured to move the door into the closed position responsive to receipt of a signal, and the closing mechanism is configured to allow movement of the door between the open position and the closed position in absence of the signal.

A belt tensioning system (170) for tensioning a belt (171) of a belt drive system (970) for transferring torque from a drive unit (112) of a door operating system (100) to a sliding door leaf (101) of a sliding door assembly (200), the belt tensioning system comprising a belt wheel (176) connectable to the belt (171) for torque transfer between said belt wheel (176) and an additional belt wheel (175) of the belt drive system (970); a belt wheel guiding arrangement (330), the belt wheel (176) being movably connected to said belt wheel guiding arrangement (330); and a belt tensioning arrangement (470) operatively connecting the belt wheel (176) and the belt wheel guiding arrangement (330) for adjusting the position of the belt wheel (176) relative the belt wheel guiding arrangement (330).
