Description

The invention relates to a bridge of a transition between two articulated vehicle parts, such as a multi-unit rail vehicle, comprising a provided for arrangement on each vehicle part base plate and a center plate, wherein the center plate is connectable by at least one variable in length centering device with the vehicle parts, wherein the central plate has at least one pair of telescopes, which is vorschenden for connection with the two vehicle parts, wherein each telescope of Teleskoppaares is vorstellen for arrangement on a vehicle part.

The bridge, as part of a transition between two articulated vehicle parts, is well known in the art. Such a transition includes not only the bridge, but also a bridge surrounding the bridge in a U-shaped or box-like manner. The bridge itself can be present in a variety of designs, for. B. be designed as a link bridge or consist of bridge plates. In this context, from the prior art according to the EP 1 564 101 B1 a bridge of a transition known, comprising a arranged on each one vehicle part base plate, and a resting on the bottom plates footboard. The floor panels are in this case attached by a hinge to the respective vehicle part. In order to prevent lifting of the tread plate of the floor panels with rolling movement of the vehicle parts relative to each other, a support is provided on the underside of the tread plate, which has two arms which engage under the floor panels. A similar device results from the US 6,443,070 B1 , wherein in each case a centering device in the form of a scissors frame is provided for centering the tread plate relative to the two base plates on both sides of the vehicle central longitudinal axis. The scissors frame itself is hinged here on the underside of the footboard.

A similar bridge construction results from the EP 2 157 006 B1 , Inasmuch as there is also provided a tread plate, wherein the tread plate on the underside on both sides of the central longitudinal axis each having two pivotable arms which engage in the initial state of the bottom plates, so as to prevent lifting of the tread plate of the bottom plates.

Also from the EP 1 001 501 3 a similar device is known, in which case the resting on the bottom plates tread plate by two to held on both sides of the central longitudinal axis of the vehicle extending double scissors and is centered.

A bridge of the type mentioned in particular finds application in high-speed trains, in which bridge bridges were previously used. Such link bridges (De 295 00 795.6 U1) have the advantage that they allow the passage of relatively tight curves, without this leading to a gap formation between the links. However, the clear passage width is limited here. In addition, the link bridges are expensive and heavy.

From the DE 29 08 354 A1 a transition device of the type mentioned is known. In this case, two mutually opposite hubs are provided, between which there is a formed as a plate connecting part. Below the turntables are three telescopes, with two hinged to one car body and a middle to the other goods box. The telescopes are also connected to the formed as a plate connecting part. The telescopes are spring loaded.

The object underlying the invention is to provide a bridge of the type mentioned, with the tight curve radii can be traversed, but which is able to provide a large clear transition width, and which is also inexpensive to produce.

To achieve the object, the invention proposes that for receiving the Teleskoppaares on the center plate a support is provided, wherein the carrier receives the centering device, wherein the centering device comprises a pivot arm and two scissor arms, wherein the pivot arm on the carrier and the scissor arms respectively a telescopic rod or the respective vehicle part are rotatably arranged. That is, both the pivot arm and the scissor arms are connected by a hinge with the corresponding components, ie the carrier and in particular the telescopic rod. As already explained, the middle plate has a pair of telescopes on both sides of the central longitudinal axis, wherein each telescope pair is assigned a centering device. Here, a pair of telescopes is located on both sides of the central longitudinal axis of the bridge. By arranging two telescopes as a pair next to each other, each telescope is connected to a vehicle part, it is achieved that when cornering with a corresponding width of the center plate a higher extension distance can be provided, ie, that even with tight curves covering the floor panels with the Center plate is given, without causing this column, which also results in a larger clear passage width, just because of the greater coverage of the bottom plates with the center plate when the center plate is chosen wider.

Advantageous features and embodiments of the invention will become apparent from the dependent claims.

For example, it is provided that the telescope comprises a telescopic sleeve and a telescopic rod guided through the telescopic sleeve, wherein the telescopic sleeve is arranged on the central plate. The telescopic rod itself is articulated to the vehicle part, in particular by a pivot bearing with a horizontal axis in the installed state. This ensures that especially pitching movements can be recorded, as they arise when such vehicles by sinks or drive over hills. To a limited extent, it is also possible to take up rolling movements, although it should be noted that, in particular in the case of high-speed rail vehicles, the rolling movements that occur are rather small.

Of course, such a bridge of a transition must also be able to give way to kinking movements. That is, when such an articulated vehicle drives through a curve, the bridge should be able to follow such movements.

Now it is known that the curve radii are relatively large, especially in high-speed lines. In general, however, when driving through curves, ie when buckling the transition, the two telescope pairs reduce their distance from each other. That is, at least one of the telescope pairs is attached to the center plate or the vehicle part so that it can move to the other pair of telescopes. According to a first embodiment, it may be provided in this case to design the carrier of at least one telescopic pair so that it can move laterally relative to the center plate. This can be accomplished by providing the carrier with a slot extending in the direction transverse to the longitudinal axis of the vehicle, with a bolt provided on the center plate received by the slot in the carrier. Along the slot can thus move the carrier relative to the center plate.

Alternatively, the telescope pairs may be attached with lateral play on the respective vehicle part. That is, the telescopes of each Teleskoppaares are laterally, so articulated in the direction transverse to the longitudinal axis of the vehicle slidably on the vehicle part. It is also conceivable, a combination of both.

According to a further feature of the invention it is provided that the telescope of a telescopic pair is connected by an adapter to the vehicle part. The adapter is in this case connected to the car body by a hinge with a horizontal axis to accommodate pitching movements, such as occur when such a vehicle drives through a dip or over a dome. In connection with the aforementioned lateral play of the telescopes transverse to the longitudinal axis of the vehicle is advantageously provided to store the adapter with lateral play slidably on the horizontal axis.

Now, however, it is also known that the vehicle must be able to follow lateral offset movements, as they occur when such a vehicle, for example, drives over a switch. In this context, it is provided according to a feature of the invention that the telescopic pair is horizontally pivotable in the installed state. In particular, the adapter is connected to the telescope by a vertical axis in the installed state, so that each telescope of a telescopic pair is horizontally pivotable. It follows that the telescope pair can be pivoted horizontally

It has already been pointed out that the base plates in the installed state rest on the middle plate. The floor panels themselves are connected by a hinge with the respective vehicle part. In the area of the support of the bottom plates on the middle plate, sliding strips are provided, in particular made of plastic, in order to avoid a movement of "metal on metal".

The bridge, generally designated 1, comprises the two base plates 2, 3, which are in each case connected via a hinge 4, 5 to the respective vehicle part 6, 7. The bottom plate 2, 3 has in the region of its front end in each case a slide bar 8, 9, with which the bottom plates 2, 3 rests on the middle plate 10. The bottom plates 2, 3 are respectively chamfered in the end region (arrow 2a, 3a), so that when passing through tight curves, the two bottom plates 2, 3 can move very far towards one another in this region.

On both sides of the central longitudinal axis 30 is located on the underside of the center plate a designated 20 Teleskoppaar. The telescope pair 20 comprises two telescopes 21, 22, wherein each telescope 21, 22 has a telescopic sleeve 21 a, 22 a, through which a telescopic rod 21 b, 22 b is slidably receivable. Each telescopic rod 21 b, 22 b is connected at the end by an adapter 23 by a rotary joint 24 with a horizontal axis 24 a with the respective vehicle part 6, 7. The telescopic sleeves 21 a, 22 a are held by the carrier 11 on the underside of the middle plate 10. The span of the bridge is determined by the length of the telescopes and by the fact that both telescopes provide part of the range. The telescopes of a telescope pair thus form a series circuit.

In conjunction with the Teleskoppaar 20 is designated 40 centering device. The centering device comprises in detail a pivoting arm 41 and two scissor arms 43 articulated thereon. The scissor arms are connected at the end to the telescopic rod 22b, specifically in the area of the adapter 23. The connection between the scissor arms 43 and the telescopic rod 21b, 22b is also here articulated. About a hinge 45 with a vertical axis of rotation 45 a, the pivot arm 41 is articulated to the carrier 11.

It has already been pointed out that the carrier 11 serves to receive the telescopes 21, 22. Telescopes are connected via the respective telescopic rod 21 b, 22 b with the respective vehicle part. It is essential here that the middle plate 10 is held supported by the telescopic pair 20 with the carrier 11. That is, both the weight of the center panel and the people passing overhead are received via the telescoping pairs 20 mounted on either side of the center longitudinal axis of the vehicle below the center panel. The centering device itself assumes no supporting function, this has only the task, as is clear from the term "centering", to ensure that the center plate 10, which is always located centrally between the two bottom plates 2, 3.

From the Fig. 3 and 3a It can be seen that the carrier designated 11 has a slot 12 which serves to receive a bolt, wherein the bolt can also be the axis of rotation 45a of the joint 45. The rotation axis 45a is fixed to the underside of the center plate 10. The slot 12 is located exactly between the two telescopes 21, 22 of a pair of telescopes, in particular, each carrier for a pair of telescopes such a slot 12 has to provide the required transverse mobility of the carrier and thus of the telescopic pair when cornering.

Fig. 5 shows in a variant to this, that the adapter 23 is received with the bore 23 a with lateral play 26 through the axis 24 a of the rotary joint 24. This also allows, similar to a parallelogram link, the change in the distance between the two telescope pairs during cornering of the vehicle.

Out Fig. 4 In this context, not only the connection of the telescope 23 by the horizontally extending axis 24a of the pivot joint 24 in the installed state on the vehicle part recognizable, but also the connection of the telescope 21, 22 to the adapter 23 by a vertical axis 25 in the installed state That is, each of the telescopes of a telescopic pair is connected in this way by the adapter 23 to the respective vehicle part 6, 7. Rolling movements can be absorbed by the horizontal axis, as occurs when such a vehicle drives through a depression or a dome, whereas offset movements can be recorded by the vertical axis, as occur when such a vehicle travels over a switch ,
