Description

The present invention relates to a door suspension and drive mechanism, in particular for rail vehicles.

There are known and used door suspension and drive mechanisms, in which the drive cylinders lie opposite to each other and rest with one end in the side wall of the car on the sides of the door blank, the other are attached to the door suspension bags, and the locking locks are located on the sides in the lower part door.

Also known is a solution in which one actuator drives two door panels coupled with each other by a chain or a cable.

There are also known solutions presented in the studies of IFE (Industrie Einrichtungen Fertigungs - Aktiengesellschaft, Waidhofen, Austria) entitled "Turen fur Schinenverkehrsmittel".

Also known is a set of sliding doors from the patent PL 162948, used, inter alia, in railway freight cars, providing a method of suspending and securing the running gear along the guides.

The disadvantages of the described solutions are the buckling nature of the actuators' operation, causing their unsealing and premature wear, complex structure of locking locks and difficult access to these locks for their adjustment, difficult adjustment of the door leaf position in relation to the door opening, elongation of chain elements or cables in the case of a coupled drive complex guides for the rolling elements.

The object of the invention is to create such a structure of the door suspension and drive mechanism, especially for rail vehicles, which would provide a simple structure combining all the elements of the drive and suspension mechanism into one whole.

According to the invention, this task has been accomplished by making a simple door and drive suspension mechanism which also prevents deliberate opening while driving.

The essence of the solution of the door suspension and drive mechanism according to the invention is that the door drive actuators are mounted directly one above the other on common brackets and cooperate with external carriages, while the internal carriages cooperate with locking locks, while the locking lock has a three-arm lever with a securing claw, pusher and release, and a bolt with a locking surface and a control surface.

The three-arm lever is controlled by the inner carriage by the pusher and is fixed by the lever spring, while the bolt is actuated by the lock actuator by the control surface, the lock actuator being connected by a pneumatic line to the electropneumatic valve.

The outer carriages and the inner carriages have recesses for securing the slings of the door panels, but the slings have bean-shaped recesses, and the inner carriages have wedge-shaped recesses for mating with the securing claw of the three-arm lock lever.

The locking lock has a three-arm lever with a safety claw, pusher and release, and a bolt with a locking surface and control surface.

The advantage of the door suspension and drive mechanism according to the invention is that it eliminates the indicated disadvantages and inconveniences, as it does not cause buckling of the actuators, allows easy adjustment and simple access to the drive by placing the actuators centrally over the door opening, which allows for simple adjustment of the position of the door leafs in vertical and enables the use of a simple door lock as a function of vehicle speed, which is of great importance for the safety of passengers. Another advantage is that to enable simple installation, a mounting angle was used that connects all the elements of the drive and suspension mechanism into one whole.

The subject of the invention is shown in the embodiment in the drawing, in which fig. 1 shows a general view of the suspension and drive mechanism, fig. 2 - view of the outer trolley with door panel suspension, fig. 3 - cross-section through the suspension and drive mechanism, while fig. 4 - locking locks view.

On the mounting angle 1 fixed to the roof strap 2 with shaped bolts 3 and nuts 4 there is mounted a running rail 5 with external carriages 6 and internal carriages 7 with trolley cutouts 8. On carriages 6 and 7, by means of slings 9 placed in the recesses 8 are hung door panels 10. The slings 9 have slotted cutouts 11 and are connected to the carriages 6 and 7 by means of bolts 12 and pins 13.

Pneumatic cylinders 14 are attached to the mounting brackets 1 via the bracket 15 and the bracket 16. Pneumatic cylinders 14 are connected to the external carriages 6 by the drivers 17, and the internal carriages 7 with wedge recesses 18 cooperate with the locking locks 19. The locking lock 19 has a body 20 fixed to the mounting bracket with 1 bolts 21. A three-arm lever 22 with a securing claw 23, a pusher 24, a release 25 and a lever spring 26 and a bolt 27 with a locking surface 28, a control surface 29 and a bolt spring 30 are mounted on the lock body 20. The bolt 27 is actuated a bolt actuator 31 connected by a pneumatic conduit 32 to an electro-pneumatic valve 33 supplied from the railcar's installation.

The door hold-up operation is as follows:

In the closing phase of the door, the inner carriage 1 of the sling 9 presses against the pusher 24, causing the rotation of the three-arm lever 22 such that the safety claw 23 is placed in the wedge recess 18 of the inner carriage 7. When the desired speed is exceeded, the electro-pneumatic valve 33 supplies air under pressure to the locking cylinder 31, which causes the bolt 27 to rotate and the three-arm lever 22 to be locked in the door locked position. The lock is released by venting the lock cylinders 31 through the electro-pneumatic valve 33, which causes the lock 27 to rotate by means of the spring 26 into the unlocked position.
