Description

The invention relates to a bridge of a transition with a tunnel-shaped circulating bellows between two interconnected by an articulated vehicle, the bridge comprising a tread plate and two floor panels, each floor panel is in the region of the front of a vehicle with the vehicle in communication, said Tread plate rests on the bottom plates, wherein for centering the Tread plate is provided relative to the bottom plates in the passage direction on the underside of the bridge at least one centering, wherein the at least one centering member is on the one hand with the tread plate and on the other hand with the respective vehicle in combination.

Bridges of the type mentioned are known. Thus, in particular link bridges are known, which are used in short coupled vehicles with central buffer coupling. The use of link bridges in such short-coupled vehicles with central buffer coupling takes place insofar as sets in these vehicles when driving through curves, a relatively high transverse offset. Link bridges, as for example from the EP 0331121 A2 are known, are in principle able to meet the requirements for the transverse offset when passing through curves. Other embodiments of link bridges are for example from the EP 0669243B1 , the EP 0958981 B1 and also from the EP 0722873 B1 known.

In addition, bridge constructions are known, consisting essentially of a so-called tread plate, which rests laterally on a respective bottom plate, wherein the two bottom plates are each hinged to a vehicle part. In order to prevent lifting of the tread plate of the floor panels, devices are disposed under the tread plate, which engage under the bottom plate. A bridge of the type described above is for example from the EP 2157006 A1 known or even from the EP 1564101 B1 , Such bridges have been used in vehicles that have bogies, for example, so-called Jakobs bogies. In a multi-unit vehicle in which the individual vehicle parts rest on such Jakobs bogies, occurs essentially no cross-offset when driving through curves.

In this context is from the US 6,443,070 B1 a bridge of a transition between two articulated vehicles known, in which a tread plate is provided which rests on two floor panels, wherein each floor panel is disposed on a vehicle part. To control the movement of the tread plate relative to the floor panels when driving through curves, a scissor rack is provided under the bridge on both sides of the central longitudinal axis of the bridge. The scissor frame is connected on the one hand in the region of the bottom plates with the respective vehicle part and on the other hand, centered with the footboard. The connection of the respective scissors-type frame with the footboard is obviously carried out by at least one floating bearing. In this respect, this design is capable of briefly coupled vehicles z. B. to be used with a central buffer coupling, so in vehicles in which when driving through curves, a relatively large transverse offset between the tread plate on the one hand and the bottom plates on the other hand occurs.

From the EP 24 57 796 A1 is a bridge of a transition between two interconnected by an articulated connection vehicles of the type mentioned above, wherein the bridge comprises a tread plate and two bottom plates. The articulated connection is in this case designed in particular as a central buffer coupling. Each base plate is in the region of the front of the vehicle with the vehicle in conjunction. Between the two floor panels, which are arranged on the vehicle, there is a footboard, which rests on the floor panels. For centering the tread plate relative to the bottom plates seen in the passage direction during the travel movement, at least one centering member is provided on the underside of the bridge. This one centering is on the one hand with the tread plate and on the other hand with the respective vehicle in conjunction, so that the tread plate is always centered centered between the two vehicles on the two floor panels.

The transition includes a bellows next to the bridge. The bellows may be formed tunnel-shaped circumferential between the articulated connection on the one hand and the bridge on the other hand, but it may also include the articulated connection, in particular a central buffer coupling. The space below the bridge, which, as already stated, is formed by the tread plate and the two bottom plates, is not hermetically sealed by the bridge. Especially in winter, dirt, salt, grit and the like accumulates in the bottom area of the bellows. In addition, there is often water on the bottom of the bellows or even ice in winter.

It is therefore necessary that the bellows bottom is cleaned at certain intervals in order to obtain the life of the bellows as a whole, as well as to allow access to the clutch for maintenance purposes.

Insofar is already out of the aforementioned EP 24 57 796 A1 it is known to remove the footboard to clean the bellows floor from the inside with the tread plate and raised floor panels. However, located below the tread plate and and the two bottom plates, the two parallel to the longitudinal axis of the vehicle extending centering members, in the case of the aforementioned EP 24 57 796 are designed as double scissors. These scissors prevent easy access to the bellows bottom.

The object underlying the invention is therefore to ensure at a bridge of a transition between two interconnected by an articulated connection vehicles of the type mentioned in that the bottom of the bellows is to clean without restrictions and the clutch is optionally accessible.

To achieve the object, the invention proposes that between the at least one centering member and the respective vehicle a first or a second connection means is provided, wherein the first and the second connection means are formed such that the at least one centering member from the region of the bellows bottom can be brought , If on both sides of the central longitudinal axis of the vehicle, in each case such a centering member is provided, which is designed in particular as a scissors-type frame and in particular as a pair of scissors, both centering members should be able to be brought together from the region of the bellows base.

Advantageous features and embodiments of the invention can be found in the dependent claims.

Thus, according to a first embodiment, the bridge to both ends by a releasable connection means with the respective vehicle in connection, or in other words between the bridge and the car body, a releasable connection is provided. This has the consequence that the bottom plates including the tread plate and the centering or the members of the bellows bottom are removable.

Another embodiment, which is much easier to handle, according to the invention is characterized in that the first connecting means comprises a pivot joint, wherein the pivot joint is in communication with the one vehicle, wherein the other second connecting means forms a detachable connection with the other vehicle , From this it is clear that when the second connecting device is released from the corresponding vehicle, the bridge can be pivoted upwards, that is, in the direction of the bellows roof. It is then almost perpendicular or inclined in the direction of the vehicle, so then from the other side, the is called from the other vehicle ago the bellows bottom is accessible from the inside.

In detail, it is provided in this connection that the first connection device comprises a first carrier arranged on the first base plate, which receives the one end of the at least one centering element. In this case, preferably, a first carrier in the horizontal position of the at least one centering member is mounted on a first cross member arranged on the vehicle, wherein the cross member may be connected to the vehicle by the pivot joint. That is, the connecting device comprises both the carrier and the cross member, but the traverse forms the bearing point for the carrier. Here, the bottom plate is pivotally mounted on the first pivot joint. The first pivot joint itself is located on the vehicle, in particular in the region of the front side of the car body of the vehicle.

For releasably connecting the at least one centering member to the vehicle, the second base plate has a second carrier for receiving the at least one second end of the at least one centering member. The second bracket communicates with the second floor panel through a second pivot joint, the second pivot joint further showing an overlap panel to the floor of the vehicle. The second carrier rests on a arranged on the corresponding second vehicle second crossmember, which is arranged on the end face of this second vehicle. In order to prevent that this detachable, aufschwenkbare end of the bridge moves in the vertical direction while driving, the second carrier is releasably connected by a locking device with the second vehicle. The locking device has a finger which can be disengaged from an opening arranged on the carrier. Specifically, it is provided in this context that at the respective lateral end of the carrier, a wall is provided which has a corresponding opening for the finger. The finger itself is mounted in a bearing block, wherein the bearing block is fixed to the front side of the vehicle. The axial displaceability of the finger can be carried out by, for example, pivoting a lever via a rotatable square, wherein the one end of the finger is articulated to the lever in an articulated manner. Preferably, in this case, the finger is under the load of a spring, so that while driving, that is, in the position of use of the bridge, the finger is kept pressed by the spring in the opening. This type of locking is advantageously provided on both sides of the bridge, that is to say with respect to the support on each side of the bridge, so that to remove the tread plate with the centering members, the locking devices on each side of the bridge must be released.

Both at the end of the bridge, where a detachable from the corresponding vehicle connection is provided, as well as at the end of the bridge on which the bridge is pivotally mounted, the bottom plates are held by a respective pivot joint, said pivot joint and the pivot joint for Swing up the bridge can form. This has the consequence that the bottom plates are swung open. The tread plate is preferably releasably connected to the at least one centering, so that after removing the foot plate, the bottom plates are swung open and the floor space of the bellows so far, although limited, because of the centering, but still accessible.

As shown FIG. 1 the bridge has the reference numeral 1 as a whole. The bridge 1 connects the two vehicles 2, 3, the bridge comprising the two base plates 4, 5, on which the foot plate designated 6 supports. The bridge is surrounded by the bellows 1a, which is arranged schematically between the vehicles. The bellows 1a forms with the bridge 1 the transition. That's the two vehicles connecting joint has been omitted for the sake of clarity. The bottom plate 4 is connected to the bottom 2 a of the vehicle body 2 by a pivot joint 4 a in the form of a hinge. The bottom plate 5 also shows a pivot joint 5a in the form of a hinge which communicates with an overlap plate 7 with the bottom 3a of the car body of the vehicle 3. That is, the overlapping plate forms the transition to the bottom 3a of the car body of the vehicle 3. This means that the bottom plates 4, 5 can be swung open after lifting the tread plate.

The details of the structural design of the bridge are now in intuition FIG. 2 , In particular, it can be seen that on both sides of the central longitudinal axis 8 in each case a scissors-type frame 10 is arranged as a centering element for the tread plate 6 between the two vehicles 2, 3. The scissors-type frame 10 comprises scissor arms 13, 14, 15 as double scissors, wherein at the point of intersection 12 of the two scissor arms 13, 14 the connection between the scissor frame 10 on the one hand and the step plate 6 on the other hand is effected by the coupling device 20. As already stated, each of the two scissor racks 10 in the region of the respective crossing point 12 is connected to the tread plate 6 by the coupling device 20.

The coupling device 20 is described in detail in the FIG. 3 and also in the FIGS. 3a . 3b shown. In the following, the connection of the tread plate to the scissor frame will first be shown as a detachable bearing (floating bearing). The tread plate 6 has on its underside on a support plate 6a, wherein on the support plate 6a, two guide rails 23, 24 are arranged. The guide rails 23, 24 each have a slot 23 a, 24 a, wherein between the two guide rails 23, 24 as this continues to be in the view of FIG. 3a results, the carriage 22 is provided, which has two guide pins 25, wherein by means of the guide pins 25, which protrude on both sides of the carriage and in the slot 23a, 24a are guided, a displacement of the carriage 22 in the direction of the arrow 26 is made possible, which means that this connection of the tread plate is formed on the scissors frame as a floating bearing. The carrier plate 6a, the guide rails 23, 24 and the carriage 22 form the carrier 21st

The arranged on the opposite scissors frame coupling device may be formed as a fixed bearing, which means that the mobility of the carriage 22 is prevented in the direction of the double arrow 26.

The carriage 22 as part of the carrier 21 has on its underside the locking member 27. The locking member 27, which is fixedly connected to the carriage 22, has on its circumference a circumferential groove 27 a. The groove 27a is part of the latching device 28, comprising a latching tooth 29, a spring 30 and a pull cable 31. The latching device is mounted in the head bolt 33, which is in communication with the scissor rack. In the circumferential groove 27a engages the designated notch tooth 29, as this is in the view of FIG. 3 results. The latching tooth 29 is under the load of the spring 30, wherein the latching tooth 29 is also in communication with the pull cable 31 that through the corresponding openings 6 b (FIG. Fig. 2 ) is guided in the lateral edge region of the tread plate 6 upwards to disengage the locking tooth 29 against the force of the spring 30 from the circumferential groove 27 a. The latching tooth 29 is mounted in a sleeve 29 a, which is firmly connected to the scissors frame. That is, move the scissor arms 13, 14 due to a movement of the scissors-type frame 10, then the locking tooth 29 rotates relative to the locking member 27 in the circumferential groove 27 a. In the starting position, that is, when standing in a line vehicle, it is, however, so that the locking tooth 29 extends in its longitudinal direction transverse to the longitudinal axis of the vehicle, that is, that the traction cable 31 does not engage at an angle to the locking tooth.

The scissors-type frame 10 is articulated on the spherical bearing 11 (FIG. Fig. 5 Each of these scissor arms is a spring element 40 is arranged as a support element, the end has a head 41, wherein the head 41 made of a plastic resiliently against the respective bottom plate 4, 5, is pressed. Thus, if the bottom plate 4, 5 under the load of the spring elements 40, then this is the bottom plate 4, 5, since it is connected by the hinge 4a, 5a with the vehicle part, held pressed against the footboard. This with the result that due to the elastically yielding design of the tread plate itself, for example by the use of a PU material, the step formation between the bottom plates on the one hand and the tread plate on the other hand is prevented. From this it is clear that in extreme roll, pitch and kink movements possibly also with transverse offset of the vehicles, by the pressure of the bottom plate against the tread plate, the tread plate is deformed in the installed state upwards and thus biased in the vertical direction. The support member may also be a buck, z. B. plastic.

Out FIG. 4 is also the connection of the scissors-type frame 10 to the vehicle 2, 3 recognizable, wherein the FIG. 5 an enlarged view of the detail V from FIG. 4 shows. This in FIG. 5 shown spherical bearing 11 comprises a bearing pin 11 a with a spherical collar 11 b on which a likewise spherically formed saddle 11 c rests, which is in communication with the scissor arm 15, 14. Such spherical bearings are state of the art, and so a detailed description of this bearing is unnecessary.

Out Fig. 6 In detail, the pivotable connection of the bridge 1 to the car body of the vehicle 2 by the first connection means 53. In this case, a pivot joint 4a is provided in the form of a hinge or hinge strip, for example, in the region of the bottom 2a of the car body of the vehicle 2 is attached by a weld. Bridge side takes the pivot joint 4 a, the bottom plate 4 pivotally. Approximately at right angles to the bottom plate 4, the first cross member 50 extends. The Traverse is hereby arranged directly on the car body. It can also be additionally attached to the pivot joint 4a. This first cross member 50 is formed at right angles in the cross section in the manner of an "L". In the direction of the bridge 1, a likewise right-angled, L-shaped first carrier 51 is arranged on the bottom plate immediately in front of the pivot joint 4 a, which runs approximately parallel to the also right-angled cross member 50. The first carrier 51 serves to receive the spherical bearing 11. The first carrier 51 is supported relative to the cross member 50 via plastic buffer 55 both laterally and downwardly, as shown directly in the view of FIG Fig. 6 results.

Looking now at the Fig. 7 , the following results with respect to the second connecting device 63: The car body of the vehicle 3 receives the second cross member 60. The second cross member 60 is formed in cross section as well as the first cross member substantially rectangular (L-shaped). This second cross member 60 is attached to the end wall of the vehicle 3, as is shown in the view of Fig. 7 results. Furthermore, a pivot joint 5a is provided, wherein the pivot joint 5a on the bridge side receives the bottom plate 5. Running at the opposite end in an alignment with the base plate 5, there is the so-called overlap plate 7 on the pivot joint 5a. The overlap plate 7 rests on the floor 3a of the car body of the vehicle 3. Running at right angles to the bottom plate 5, the joint also has the also in cross section rectangular, L-shaped second carrier 61, wherein the carrier 61, the spherical bearing 11 of the scissors frame 10 absorbs. Also, the carrier 61 is supported on plastic buffer 65 both laterally and vertically on the second cross member 60 from.

As can be seen, the second carrier is mounted on the horizontal leg of the second cross-member 60. That is, when driving the vehicle, there is the possibility, especially on uneven road, that the bridge lifts unintentionally. This means that the overlap plate or the entire bridge in the region of the second cross member pivots vertically upwards. To prevent this, a locking device 70 is provided ( Fig. 8 ). This locking device 70 comprises a finger 71, which is connected by a lever 72 with a rotatable square 73, wherein the lever is pivotally mounted on the finger 71. By pivoting the lever 72 is pivoted in the clockwise direction by turning the square 73 of the fingers 71 from an opening 67, wherein the opening 67 is located in a vertical wall 68 on the horizontal leg of the second carrier. This wall 68 is arranged at the end of the carrier, so that the locking device 70 is fixed by the bearing block 69 for receiving the square 73 on the front side of the car body of the vehicle 3. The finger 71 is under the load of a spring 71 a, which ensures that the finger is always in the opening 67.

There is the possibility of the formation of the second connection means 63 according to the FIGS. 7 and 8th provided to both ends of the bridge, so that then after releasing the fingers 71 of the locking devices 70, the complete bridge including the centering, that is, the scissor racks and the bottom plates, can be removed. It is also conceivable to show the locking device on both sides of the bridge.

However, the connection of the bridge is taken in the form as they are in the FIGS. 6 on the one hand and 7 and 8 on the other hand, so only the finger 71 of the locking device 70 is released at the first end of the bridge to then pivot the entire bridge including the overlap plate 7 in the direction of the bellows roof, and thus free access to get to the bellows bottom, since, as stated, the centering members so in the present case, the two scissor racks are swung with.
