Second, the door panel must move sideways to clear the door opening
[0005] However, drive motors that can be displaced relative to the vehicle or mounted on movable parts require movement of the supply cables, which is disadvantageous in terms of reliability and production costs
Another disadvantage of this type of door drive is that due to the heavy drive motor and corresponding drive mechanism, a huge mass has to be moved out and back together with the door panel, which slows down the opening and closing process of the sliding door
The known door operators therefore require a relatively large installation space

Embodiment Construction
[0032] figure 1 A box body 3 of a public transport vehicle is shown, which box body 3 includes a box body body 31 , a box body window 32 and several doors 2 . Each door 2 comprises two door panels 20A, 20B. In order to open and close the door panels 20A, 20B, the door 2 is equipped with a door drive 1 (not in figure 1 shown in ). The door operator 1 will be described in more detail with reference to the drawings.
[0033] figure 1 The car body 3 is a car body 3 of a public transport vehicle, in particular a car body 3 of a subway train, and figure 1 The car body 3 is used as an example for all other public transport vehicles such as railway trains, buses, airplanes, cable cars, trams and others.
[0034] such as having figure 1 Public transport vehicles such as the public transport vehicles of the box body 3 shown in the figure are to get on and off the vehicle through the door. Typically, sliding doors such as figure 1 The door 2 shown in is for this vehicle.

The invention relates to a door drive device for a door (2) of a wagon (3), comprising at least one door panel mount (12A, 12B) displaceable along a first spatial axis (Y) substantially vertical to the plane of a door panel (20A, 20B) mounted on the at least one door panel mount (12A, 12B) and along a second spatial axis (X) extending substantially horizontal in use and substantially vertical to the first spatial axis (Y), a drive motor (14) and a spindle (15) which may be rotated by means of the drive motor (14). It is provided, that a displacement of the at least one door panel mount (12A, 12B) along the first and / or second spatial axis (Y, X) is effected by means of a guide fork (13A, 13B) being displaceable by an associated spindle nut (16A, 16B) slidably engaged with the guide fork (13A, 13B), wherein the spindle nut (16A, 16B) is driven by rotation of a spindle (15) and wherein the spindle (15) and the drive motor (14) are fixed with respect to the wagon (3).
Description
technical field [0001] The invention relates to a door operator according to claim 1 , to a door according to claim 14 and to a car body according to claim 15 . Background technique [0002] Sliding doors are commonly used in public transport vehicles. In the closed state, the door panel of such a door is located in the wall of the vehicle, and in the open state, the door panel is located on the top of the wall of the vehicle adjacent to the door opening. In order to bring a sliding door from a closed position to an open position, the door panel must first be moved outside the walls of the vehicle, ie almost perpendicular to the longitudinal axis of the vehicle. Second, the door panel must move sideways to clear the door opening. In order to return the sliding door from the open position to the closed position, the same movement must be performed in the opposite direction and in the reverse order. [0003] A door drive or actuator is necessary to carry out said movement o...
