Abstract:
Drive apparatus, for the automatic actuation of a sliding door of a motor vehicle, comprising a fast running motor, the motor shaft of which is connected to a transmission with a large step-down ration, the transmission having a first gear wheel, which is secured against rotation, via a releasable blocking device that allows rotation of the first gear wheel when released, and a second rotatable gear wheel, which is rotationally fixedly connected to an output drive gear and which is rotatable relative to the first gear wheel by the rotation of the motor when the first gear wheel is blocked, with the number of teeth of the first gear wheel only differing by a few teeth from the number of teeth of the second hear wheel and with the large step-down ration being determined by this difference of the tooth numbers.
