Description

The invention relates to a nose flap assembly for track guided vehicles according to the independent protection claim 1. In particular, the invention relates to a Bugklappenanordnung for rail vehicles, wherein the Bugklappenanordnung is designed to cover a coupling device of a rail vehicle or expose.

From rail vehicle technology, it is known the front side, d. H. To provide the bow of a track-guided vehicle with a protective cover to protect a provided on the vehicle front side coupling, in particular the coupling head from the weather, such as snow, icing, moisture and dirt, as long as the clutch is not used and in its uncoupled state. For this purpose, so-called front modules are often used, which are mounted on the vehicle front side. A front module usually has at least one nose flap, which is pivotable relative to the vehicle undercarriage and provided on the vehicle front side coupling to expose the coupling shaft when needed.

The term "nose flap" is understood here as the cladding of the coupling shaft, which covers the coupling shaft in the front in its closed state, on the one hand to protect the coupling components from the weather and on the other to avoid aerodynamically adverse frontal, which is particularly important for streamlined trainsets, such as high-speed trains ,

From the prior art it is known in this regard to form a said protective cover of the front modules with a Bugklappenanordnung consisting of several flap segments. In particular, conventional bow flap assemblies often include two flap segments which are synchronously pivotally mounted to the front module of the rail vehicle. In order to pivot the flap segments, at least one actuating device is usually provided, which serves to pivot the flap segments and thus, if necessary, to expose the coupling head. Of course, the conventional actuator also serves to convert the flap segments back to their closed position to protect the clutch from the weather. In addition, it is known that the individual flap segments are pulled into the interior of the front module when opening the Bugklappenanordnung. It is a well-known problem that within the front module, a relatively large space is provided to allow pulling the flap segments into the interior of the front module. In addition, it is considered problematic that the known Bugklappenanordnungen have a high susceptibility to wear and often are to operate only with considerable effort.

Due to the above-mentioned problem, the present invention seeks to provide a Bugklappenanordnung for track-guided vehicles, which requires only a small space within the front module and also has a reduced probability of failure.

According to the invention a Bugklappe according to the independent protection claim 1 is given to achieve the above object.

Accordingly, the invention relates to a Bugklappenanordnung for track-guided vehicles, especially rail vehicles, wherein the Bugklappenanordnung is designed to cover a coupling device of a vehicle or uncover. The Bugklappenanordnung invention has at least one first flap segment, which is pivotally connected to a frame of the track-guided vehicle and can be converted from a first closed position to a second open position. In addition, the Bugklappenanordnung comprises at least a second flap segment, which is slidably mounted on the frame of the track-guided vehicle and can be converted from a first closed position to a second open position. The at least one first flap segment and the at least one second flap segment can be independently transferred from their first closed position to their second open position.

The Bugklappenanordnung invention has a number of advantages over conventional solutions. Thus, the combination of the pivotally executed at least one first flap segment and the at least one displaceably executed second flap segment can be used to significantly reduce the space requirement of the Bugklappenanordnung invention in the interior of the front module. Also, the proposed actuation variant proves to be particularly long-term stability, which is why the Bugklappenanordnung invention can be used without failure even in extreme weather conditions. In addition, the space requirement can be further reduced by the independent movement of the individual flap segments and the reliability of the Bugklappenanordnung invention can be significantly increased.

Advantageous developments of the Bugklappenanordnung invention are given in the dependent claims.

Thus, it is provided according to a first embodiment of the invention Bugklappenanordnung that at least two first flap segments and at least two second flap segments are used. By dividing the Bugklappenanordnung in at least four independently movable flap segments easier positioning within the front module is possible because the individual flap segments each have a lesser extent. Also, the load on the bearings is reduced by the flap segments to be held, whereby the arrangement has a lower susceptibility to wear. Of course, it is also conceivable in this context that the Bugklappenanordnung consists of more than four (eg six) individual flap segments.

Preferably, the at least two second flap segments are arranged opposite the at least two first flap segments such that the at least two first flap segments are locked by the at least two second flap segments in the first closed position as long as the two second flap segments are in their first closed position. In other words, the at least two first flap segments according to this embodiment can be transferred to their second opened position only if the at least two second flap segments are already in their second opened position. Thus, the Bugklappenanordnung invention despite the many individual segments on a very high stability, whereby a failure of the protective cover during driving can be virtually eliminated.

Another aspect of the invention provides that the at least one second flap segment is displaceable substantially parallel to the longitudinal axis of the track-guided vehicle. In this way, the at least one second flap segment can be pulled into the front module at any time without the risk that the at least one first flap segment or the front module will be damaged.

It is also advantageous if the at least one first flap segment of the flap arrangement according to the invention is detachably connected via a carrier element to the frame of the track-guided vehicle. Accordingly, the at least one first flap segment can be easily exchanged for maintenance purposes, for example, without having to disassemble the entire front module. In addition, the at least one first flap segment is accordingly completely independent of the movement of the at least one second flap segment, since the first flap segment is connected directly to the frame.

The carrier element can be advantageously designed as a destructive or reversible energy dissipation element, whereby then the first flap segment fulfills the function of an energy dissipation device. In this context, it is conceivable that the support elements are formed, for example, as cylindrical energy-absorbing elements which serve to absorb slight shocks which occur, for example, during the maneuvering operation of the rail vehicle.

The Bugklappenanordnung invention may also comprise at least one first actuating element, which is connected to the carrier element on the one hand and with the frame on the other hand, and is adapted to transfer the at least one first flap segment from the first closed position to the second open position. By attaching a first actuating element directly to the carrier element, a simple and reliable pivoting mechanism for the at least one first flap segment is realized. The at least one first actuating element can be designed as an electrical, pneumatic or hydraulic actuator. This has the advantage that already existing energy sources such as electricity or compressed air can be used to control the flap segments.

It is also advantageous if the at least one second flap segment is connected via a guide element releasably connected to the frame of the track-guided vehicle. As already mentioned, this also serves the easier maintenance of the Bugklappenanordnung invention.

The thus fixed Bugklappenanordnung may further comprise at least one second actuating element, which is connected to the guide element and / or the at least one second flap segment on the one hand and with the frame, and is designed, the at least one second flap segment from the first closed position to the second open Position to convict. As with the at least one first actuating element, the at least one second actuating element may also be an electrical, pneumatic or hydraulic actuating element. The actuating element is arranged such that it can easily pull the at least one second flap segment into the front module or slide it out of the front module. In particular, the at least one second actuating element should be aligned parallel to the guide element in order to generate the lowest possible shear forces on the guide element.

If the Bugklappenanordnung fails unexpectedly, it is provided in a preferred development that the Bugklappenanordnung further comprises an emergency unlocking mechanism for transferring the at least one first flap segment and / or the at least one second flap segment from the first closed position to the second open position. The emergency unlocking mechanism may in particular be located at the front of the at least one first flap segment, wherein an actuation of the emergency unlocking mechanism results in that the second flap segments and / or the first flap segments are manually displaceable or pivotable.

In the following, the Bugklappenanordnung invention will be explained with reference to the embodiment shown in the drawings.

Showing:

1 : An external perspective view of an embodiment of the Bugklappenanordnung invention;

2 : a schematic view of the in 1 illustrated embodiment of the Bugklappenanordnung invention; and

3 : a cross section from the side through in the 1 illustrated embodiment of the front door according to the invention in the open state.

In the following description of the figures, identical or equivalent components are provided with the same reference numerals for reasons of clarity.

In the 1 to 3 an embodiment of the Bugklappenanordnung invention is shown for track-guided vehicles. The Bugklappenanordnung invention is designed especially for rail vehicles and serves to a coupling device 6 cover or expose the vehicle.

In detail, the Bugklappenanordnung has at least a first flap segment 1a . 1b which is pivotally connected to a frame of the track-guided vehicle and is transferred from a first closed position to a second open position. In addition, at least one second flap segment 2a . 2 B which is slidably mounted on the frame of the track-guided vehicle and can be transferred from a first closed position to a second open position. As it is in 1 and 2 is shown, the at least one first flap segment and the at least one second flap segment are arranged directly laterally next to one another in their first closed position and thus form a protective lining for the coupling device. It should be noted that the at least one first flap segment 1a . 1b is formed pivotable while the at least one second flap segment 2a . 2 B is formed displaceable in the front module. In this way, the space requirement of the front module within the front module can be significantly reduced.

The at least one first flap segment 1a . 1b and the at least one second flap segment 2a . 2 B are independently convertible from a first closed position to its second open position. While that at least a first flap segment 1a . 1b Furthermore, it can be given individually from its first closed position to its second open position, it is also completely independent of any time possible, the at least one second flap segment 2a . 2 B move from its first closed position to its second open position.

As can be seen from the drawings, the Bugklappenanordnung invention preferably four, ie at least two first flap segments 1a . 1b and at least two second flap segments 2a . 2 B on. Of course, it is also possible that the Bugklappenanordnung more than four (for example, six or eight) individual flap segments, each of which independently from their first closed position to a second open position can be transferred. The illustrated at least two second flap segments 2a . 2 B are so opposite to the at least two first flap segments 1a . 1b arranged that the at least two first flap segments 1a . 1b from the at least two second flap segments 2a . 2 B be locked in the closed position as long as the two second flap segments 2a . 2 B in their first closed position. In the embodiment shown, the at least two first flap segments 1a . 1b for example, horizontally pivotable, while the at least two second flap segments 2a . 2 B in each case next to the at least two first flap segments 1a . 1b are arranged and thus enclose them from the side. In other words, according to this embodiment, it is not possible, the at least two first flap segments 1a . 1b to pivot into its open position as long as the two second flap segments 2a . 2 B in their first closed position.

As the individual flap segments 1a . 1b . 2a . 2 B are individually controlled, it is of course also conceivable that only one side of the Bugklappenanordnung shown (for example, flap segments 1a . 2a ) while the second side (for example, flap segments 1b . 2 B ) in their closed position. For this it is only necessary, the second flap segment 2a from its first closed position to its second open position and then the first flap segment 1a to pivot in its open position.

With reference to in 2 illustrated schematic view of the Bugklappenanordnung invention should be mentioned that the at least one second flap segment 2a . 2 B is displaceable substantially parallel to the longitudinal axis of the track-guided vehicle. As can be seen, this becomes at least a second flap element 2a . 2 B to do so via a guide element 4a . 4b guided substantially parallel to the longitudinal axis. The said guide element 4a . 4b this is due to the at least one second flap segment 2a . 2 B attached and preferably detachable with the frame 3 connected to the track-guided vehicle. It should be noted that in the schematic view according to 2 only parts of the frame 3 of the track-guided vehicle are dargstellt.

For moving the at least one second flap segment 2a . 2 B has the Bugklappenanordnung on at least a second actuator, which with the guide element 4a . 4b or the at least one second flap segment 2a . 2 B on the one hand and with the frame 3 on the other hand connected and adapted to transfer the at least one second flap segment from the first closed position to the second open position (ie to move). The at least one second actuating element is preferably designed for this purpose as an electric, pneumatic or hydraulic actuating cylinder to use existing energy sources can.

The in 3 shown sectional view of the embodiment of the Bugklappenanordnung invention can be seen that the at least one first flap segment 1a . 1b is connected via at least one support element preferably releasably connected to the frame of the track-guided vehicle. In particular, this is at least one carrier element 7 over a pivot bearing 8th with the frame 3 connected to the track-guided vehicle. As can be seen, it is provided in the illustrated embodiment that the at least one first flap segment 1a . 1b with several carrier elements 7 which at the top and bottom of the at least one first flap segment 1a . 1b are arranged is connected. The at least one carrier element 7 can be advantageously designed as a destructive or reversible energy dissipation element to collisions, for example, during the Rangierbetriebs catch.

Of course, the Bugklappenanordnung also has a first actuating element (not shown), which with the support element 7 on the one hand and with the frame 3 on the other hand connected and adapted to the at least one first flap segment 1a . 1b from the first closed position to the second open position. The at least one first actuating element can - as well as the second actuating element - be designed as an electric, pneumatic or hydraulic actuating cylinder.

Finally, it should be noted that the Bugklappenanordnung invention, as in the 1 and 2 dargstellt, also an emergency unlocking mechanism 5 for manually transferring the at least one first flap segment 1a . 1b and / or the at least one second flap segment 2a . 2 B from the first closed position to the second open position. In other words, after pressing the emergency unlocking mechanism 5 is it possible to use the individual flap segments 1a . 1b . 2a . 2 B manually to pivot or move to the coupling device 6 uncover or cover.

The invention is not limited to the exemplary embodiment shown in the drawings, but results from a synopsis of all the features disclosed herein.
