Problems solved by technology

[0005] This structure has basically been verified and has been used for a long time as mentioned above, but it still has some defects: the power of the door leaf along the axis of the guide rail is transmitted through the connecting rod, and the connecting rod is generated due to this huge force. bend and shear
This force has to be transmitted via the two swivel joints, which necessitates a correspondingly robust and therefore heavy and expensive design of the connecting rod

Embodiment Construction

[0016] Fig. 1 shows the very important part for the present invention from a kind of door drive device according to the prior art, promptly a guide rail 1 that is fixedly installed on the carriage, a slide 2, a rotatable, but in addition just fixed on Main shaft 3 on the carriage, a main shaft nut 4 and a connecting rod 5 that slide seat 2 is connected with main shaft nut 4.

[0017] The carriage 2 is arranged longitudinally movable along the guide rail 1 and can pivot as indicated by the positions drawn with dotted lines. At the lower end of the slide 2 is indicated schematically by a hole 6 that a door leaf (not shown) can be fitted. The longitudinal movement of the carriage 2 along the guide rail 1 is produced by a spindle nut 4 which runs along said spindle by rotating the spindle 3 by means of a drive not shown.

[0018] The connecting rods 5 are each connected via a rotary joint to a radial projection of the spindle nut 4 and to a bearing part of the carriage 2 and are ...

Abstract

The invention relates to a drive for a sliding door or a swinging-sliding door of a rail vehicle, comprising a guide rail (1) which is fixed inside the rail vehicle and on which a carriage (2) carrying a door leaf is arranged in a longitudinally displaceable and optionally rotatable manner, and a spindle drive provided with a spindle (3) which extends parallel to the guide rail (1) and a spindle nut (4) which is connected to the carriage (2) in a fixed manner in the direction of the axis (13) of the spindle (3). The invention is characterised in that the spindle nut (4) and the carriage (2) are connected by means of a rotative sliding joint (7, 8, 10). The invention also relates to different embodiments of said basic idea.

Description

technical field [0001] The invention relates to a drive for a sliding or swinging sliding door of a rail vehicle, comprising a guide rail fixed relative to the rail vehicle and a spindle drive, on which a carriage is arranged longitudinally displaceable and optionally rotatable On the guide rail, the slide has a door leaf, the main shaft of the spindle drive extends parallel to the guide rail and the spindle nut of the spindle drive is fixedly connected to the slide along the axis of the main shaft. Background technique [0002] A similar drive is known from EP 0 461 104 A of the applicant. In this case, instead of the spindle drive, an axially acting drive is provided, the drive body of which can only be moved along a straight line extending parallel to the guide rail. The force transmission from the drive body to the slide is carried out in such a way that the drive body is arranged between the two leaves of the slide, said drive body extending perpendicularly to the guid...
