1. Drive mechanism for fully-automatic opening and closing of at least one sliding door (1), which is movable by means of a motor or motors with a greater speed on the prevailing partial opening and closing path than on the last part, and which is movable by means of a coupling device (11, 21), characterized by at least one main motor (2) driving a main shaft (5, 20) to provide the high speed, and by a low-output motor (6) driving an auxiliary shaft (8) to transmit the low speed of the door (1), and whereby both shafts act onto the same follower (11, 21). |
