Claim Text:
1. A drive system for a sliding door system comprising at least one door leaf guided along a transom, the drive system comprising: a pulley which can be rotated by a drive device; a shaft passing through the pulley and fixed relative to the pulley; an endless traction mechanism guided around the pulley for moving the at least one door leaf linked to the traction mechanism; a rotational body which is separate from the pulley and configured to be mounted for rotation in the transom, said rotational body being fixed to the shaft so that the rotational body rotates with the shaft and the pulley, the rotational body is bell-shaped and formed by a bottom wall and a circumferential envelope wall, the circumferential envelope wall having at least one aperture; a locking bolt which is configured to be displaceably supported in the transom and movable to engage the at least one aperture of the rotational body thereby preventing rotation of the pulley; and an electromechanical actuation device which moves the locking bolt in response to an impulse emitted by a locking control.
