Front wall door with automated door operation for a double-decker car transport railway carriage

The invention relates to a front wall door with automated door operation for a double-decker car transport railway carriage according to the preamble of claim 1.

DE 40 20 020 A1 describes a railway carriage for transporting passenger cars. The railway carriage essentially has two side walls, two end walls, a barrel-shaped lifting roof and two loading levels for transporting the vehicles. In order to enable cars to drive into the area between the two side walls on the respective loading level, the front side must be able to be opened. It therefore consists in the upper area of a front wall flap that swings upwards like a visor and in the lower area of a roller door consisting of several door segments. When opened, this roller door is pulled under the upper loading level if it is in a horizontal position. In order to ensure that there is sufficient space to move when loading and unloading the upper loading level, the lifting roof must also be extended upwards. Electric motors, hydraulic working cylinders, cable pulls and others are provided as means of moving the lifting roof, the front wall flap and the roller door. For practical purposes, the individual movement sequences of the aforementioned elements are necessarily coupled with one another so that a single control command triggers the necessary movement sequences.

The described design of the front wall door and its operation is structurally complex and complicated. This results in a complex and laborious workflow when opening and closing the front wall. 30

The object of the invention is to provide a bulkhead door with automated door operation for

To create railway carriages of the type mentioned above, which are simpler and
is less complicated in its construction and operation.

According to the invention, this object is achieved by the features of claim 1. Advantageous embodiments of the invention are described in more detail in the subclaims.

The solution according to the invention results in a number of advantages. The design of the front wall door in the form of a vertical swing door and the associated automated operating mechanism result in a simple and clear construction. The opening and closing process of the front wall door is safe and avoids the manual actions that were previously common.

The invention is explained in more detail below using an exemplary embodiment. The accompanying schematic drawings show:

Fig. 6 is a front view of the operating device showing the door leaves on both sides of the railway carriage and

Fig. 7 is a side view of the actuating device according to Fig. 6. 5

As can be seen from the drawings, the double-decker car transport railway wagon is designed as a covered freight wagon, essentially consisting of two side walls 1, a vehicle roof 3, a front wall door as well as a lower loading level 11 and an upper loading level 10.

The front wall door of one end consists of two front wall doors 2 with a vertical pivot axis, arranged in the same way to the vertical central longitudinal plane of the railway carriage. In a preferred embodiment, the front wall door 2 of one side consists of two door leaves 2a and 2b, the inner door leaf 2a and the outer door leaf 2b, connected to one another by a joint 14. The inner door leaf 2a is hinged to a corner column 15 of the carriage structure in a hinge 16.

To operate the door leaf 2a, a linear actuator 4 is provided, which is connected in an articulated manner to its housing at a pivot point 12 on the side wall 1. The actuator 4 can be provided with a motor or hydraulic drive. The push rod of the actuator 4 is connected to a connecting arm 5, which is mounted at the other end near the hinge 16 on the inside of the door leaf 2a at a pivot point 13. The connecting arm is advantageously designed with a double crank so that it forms a slight S-shape when viewed from above.

A link 6 is mounted on the corner column 15, which is hinged with its free end to the connecting arm 5. The link 6 should be connected in such a way that when the door leaf 2a is swung open, the connecting arm 5 is swung around the corner column 15. It is advantageous that the connection is in the first third after the

Ggr;Ngr;-Pgr;.vngr;&iacgr;&iacgr;

Connection point push rod/connecting arm 5.

A control rod is connected to the free end of the outer door leaf 2b at the articulation point 9, the other end of which is mounted on the carriage side in a bearing 8 on the carriage structure. This control rod 7 guides the door leaf 2b in a defined manner when the front wall door 2 is swung open.

It is conceivable that the bearing 8 is arranged on the height-adjustable upper loading level 10 and the articulation point 9 is arranged so that it can be adjusted in height in the door leaf 2b. The height adjustment is carried out by the positive locking of the bearing 8 with the upper loading level 10 when the door leaf 2b is swung in, see Fig. 7.

The sequence of movements when opening the front wall door 2 is described below.

In the closed state, the front wall door 2 is locked to the vehicle structure in a manner known per se. To open it, the lock is released. The push rod of the actuator 4 is extended in the direction of the front wall door 2 and the opening process of the inner door leaf 2a is initiated via the connecting arm 5. The link 6, which is operatively connected to the connecting arm 5, describes a horizontal, circular movement, whereby the door leaf 2a is hinged.

is pivoted around the corner column 15. The push rod is extended until the desired position or the end position of the front wall door 2 is reached.

As a result of the hinge connection with the inner door leaf 2a, the outer door leaf 2b is pivoted during the opening process and is forcibly guided in a defined manner by the control rod 7.

In the final position of the opened front wall door 2, a pivot angle of significantly more than 90 degrees is realized, with the outer door leaf 2b forming an acute angle to the inside of the inner door leaf 2a.

This degree of opening allows unhindered loading and unloading of the double-decker car transporter.

The closing process is initiated by retracting the push rod of the actuator 4.
