Definitions

  • the present invention relates to a bumper device for a rail vehicle, in particular rail vehicle with laterally arranged crash elements, with at least one baffle protection device having impact body with a facing away from the rail vehicle baffle and with a support structure which connects the baffle with a front end of the rail vehicle.
  • Impact devices in the context of the invention are assemblies on vehicles, in particular rail vehicles, which absorb energy in the event of a collision or an impact and thereby prevent damage to the vehicle and the cargo and passengers.
  • a bumper usually comprises one or more baffles and / or buffers which are connected to the rail vehicle at its end side via a support structure, for example a resilient linkage, in particular a plurality of telescopically cooperating hollow cylinders, into which a helical compression spring can be inserted End are connected.
  • the impact devices are arranged laterally. Between the two shock devices, the clutch is then often arranged. But there are also constructions with only one, centrally located central buffer or combinations of both variants known.
  • the following configurations of impact devices are known at the vehicle end: two lateral buffers and one central towing hook; two lateral crash buffers and one central pull hook; two side crash buffers, the second with two connected side crash elements, and a central zughaken; a central central buffer (central buffer); two lateral crash buffers and a central center buffer clutch; two lateral crash elements and a central central buffer coupling; two lateral crash buffers connected to two lateral crash elements and one central center buffer clutch.
  • the following configurations of impact devices are known: two lateral buffers and one central towing hook; two lateral crash buffers and one central pull hook; two lateral crash bumpers connected to two lateral crash elements and one central towing hook; two side bumpers connected to two side crash elements and a central center buffer clutch; central short couplings; lateral crash elements and central short couplings.
  • the anti-climb device has a grid of travel-open cells formed by interconnected planar webs such that high stiffness sites alternate with locations of lesser rigidity within the vertical plane of the grid is intended to give in the event of a collision sections of the grid and cause a toothing of the colliding vehicle fronts.
  • the anti-climb protection device only works optimally if the collision-infringing vehicle has a largely corresponding anti-climbing device, so that the two anti-climb devices can interlock with one another.
  • a vertical force arises on the usually convexly curved buffer plates of the collision-infringing vehicle, which leads to climbing.
  • the baffle is formed by a plurality of projections whose front facing away from the rail vehicle ends on a concave line and / or surface are arranged.
  • the concave shape is provided at least in the vertical, but may also be provided in the horizontal direction transverse to the direction of travel.
  • the side buffers of the collision-infringing vehicle need not necessarily have a convex curvature, as is customary in the prior art, in particular no convex curvature, which corresponds to the concave curvature of the baffle of the impact device according to the invention, but the climb is also in collision-infringing vehicles with a flat buffer surface effectively prevented.
  • the plurality of projections of which at least one, preferably all, can be formed by a horizontally extending rib, forms a Aufkletterschutz adopted that interlocks with a largely corresponding Aufkletterschutz adopted in the event of a collision such that not one of the vehicles can climb over the frame structure of the other vehicle.
  • the projections are arranged on a base plate, in particular a flat base plate, which is preferably arranged vertically.
  • the base plate may be formed integrally with the projections.
  • Such a base plate has been found to be particularly suitable to receive in a collision with a side buffer vehicle transmitted from the buffers forces, in particular vertical forces, and forward it to the support structure.
  • At least one of the projections tapers towards the front end.
  • the at least one projection preferably all the projections, tapers towards their front end.
  • the at least one projection preferably all the projections, widening towards their base, ie towards the base plate, their stability is also increased.
  • the lateral flanks of the at least one of the projections, preferably all projections at an angle of 10 to 40 °, in particular from 15 to 25 ° to run towards each other.
  • said angular range is provided at the projections, in particular at the ribs, over their entire horizontal extent. Just this angle range leads to a respect of stability and the recording of responsive anti-climber optimized shape.
  • At least four, preferably at least six projections are arranged side by side in the vertical.
  • the number of at least four, preferably at least six, projections also has the advantage that in this way the concave shape of the baffle can be realized particularly easily and that the impact energy can be distributed over many projections.
  • the baffle body or the anti-climbing device of the bumper device according to the invention can have different geometries. It has proved to be advantageous if the vertical distance between the projections is at least 20 mm, preferably at least 30 mm. With the vertical distance, the distance of the projections in the region of their base, ie at the point where they go into the base plate, meant. A large vertical distance has the advantage of optimally cooperating with the oncoming anti-climber.
  • the projections In addition to the distance between the individual projections and the vertical width at the front end may be important. It has proved to be advantageous if the projections have at their front end a vertical width of at least 10 mm, in particular of at least 20 mm, but preferably not more than the spacing of the projections in the region of their base, so that upon collision similar vehicles a mesh is guaranteed. This ensures a relatively large contact area in the event of a collision with a convex buffer of an anticollision vehicle.
  • the projections relative to the base plate by at least 10 mm, preferably by at least 15 mm, protrude.
  • the concave line is a circular arc or concave surface a spherical cap according to yet another embodiment of the inventive device in a maximum number of collision-opposing vehicles with convex domed buffers, especially side buffer vehicles, which have no suitable anti-climber protection.
  • the radius of the concave line or surface is therefore constant in this case. Basically, however, other waveforms are conceivable.
  • the radius is in a range of 1000 to 2000 mm, in particular from 1300 to 1700 mm.
  • the radius is 1500 mm.
  • the usual bulges of the baffles are optimally covered.
  • the usual distances between two side buffers and the usual vertical distances between the buffers and the rail top is in accordance Yet another embodiment of the invention shock device provided that the baffle and / or the base plate has a vertical width of at least 300 mm, in particular of at least 350 mm, and / or a horizontal length of at least 300 mm, in particular of at least 350 mm.
  • the support structure which may be formed for example by one or more cylinders, a vertical width or in the case of a cylinder has a diameter which is or is chosen so that most of the projections at least partially lie within the horizontal projection surface of the support structure.
  • a horizontal projection surface therefore, the projection surface of the component forming the support structure, for example of the cylinder, in the horizontal is meant.
  • the support structure can also be formed from one or more cylinders, wherein in the case of several cylinders, for example, these can be telescoped into one another.
  • a supporting structure can at the same time take on the function of a buffer, for example a crash buffer, and / or a crash element, preferably in the interior of the support structure, in particular in the interior of the exemplified at least one cylinder, a spring element or another force-absorbing Device is provided.
  • baffle body and support structure form a unit that combines the function of a climbing protection and the function of a buffer and / or crash element.
  • the bumper device according to the invention alone ensures the anti-climb protection and additionally at least one buffer and / or crash element, preferably two side buffers and / or crash elements, are provided at the front end of the vehicle.
  • the object is achieved by a rail vehicle, in particular a rail vehicle with laterally arranged crash elements, with at least one impact device as described above.
  • a bumper 1 of a rail vehicle 2 is shown in a side view, wherein the bumper 1 an impact body 4 with Aufkletterschutz worn 3 and facing away from the rail vehicle 2 baffle 5 and a support structure 6, here in the form of a cylinder 11, which the impact body 4 with the front end 2 'of the rail vehicle 2 connects.
  • the baffle 5 is formed by a plurality of projections 7a, 7b,..., 7f, the front ends 7a ', 7b', ..., 7f 'facing away from the rail vehicle 2 of the projections 7a, 7b, ... , 7f on a concave line X, which forms a circular arc with a radius R of 1500 mm and is part of a concave surface are arranged.
  • the projections 7a, 7b,..., 7f are arranged on a flat base plate 8, which extends vertically, that is to say perpendicular to the vehicle movement direction.
  • the vehicle movement direction is referred to as horizontal H and the vertical direction thereto as vertical V.
  • All projections 7a, 7b, ..., 7f are formed by a horizontally extending rib 9 which extends transversely to the horizontal H and vertical V.
  • the projections or ribs In a vertical section, the projections or ribs have a shape tapering towards the front end 7a ', 7b', ..., 7f '.
  • the lateral flanks of all projections 7a, 7b, ..., 7f extend over the total horizontal extension of the projections or ribs at an angle a of about 20 ° towards each other.
  • projections 7a, 7b, ..., 7f are arranged side by side in the present embodiment, in a vertical distance A of about 30 mm.
  • the projections have at their front end a vertical width B V of about 15 mm and are opposite to the base plate 8 all more than 10 mm out.
  • the middle protrusions 7c and 7d are the least prominent, whereas the protrusions, which are provided vertically outwardly, are always protruding further and further.
  • the projections 7a and 7f are the furthest, here about 30 mm with respect to the base plate 8 out.
  • Fig. 1 It can be seen clearly that the support structure 6, that is, the cylinder 11, has a horizontal projection area P T which is so large and arranged so that the projections 7c and 7d are complete and the projections 7b and 7f mostly within the horizontal projection surface P T lie.
  • FIGS. 2a ) and b) are now two different scenarios of a collision between two rail vehicles (not shown here for clarity) shown. It is in Fig. 2a ) illustrated the case that both rail vehicles have a shock device 1 according to the invention, whereas in Fig. 2b ) a case is shown in which a rail vehicle has the bumper 1 according to the invention and the other rail vehicle side buffer 1 'and no Aufklettertik.
  • Fig. 2a It is in Fig. 2a ) in the middle view of the case in which the baffles 4 of the colliding vehicles are arranged at an identical height.
  • the upper and the lower view in Fig. 2a shows an offset of 40 mm, once upwards, once in the opposite direction. In all three cases, climbing up in the vertical direction of one rail vehicle to the other is effectively prevented.
  • Fig. 2b are also shown three views in which in the middle view the baffles 4 and 4 'are arranged at the same height, while in the upper and lower view, an offset of 40 mm is shown.
  • Fig. 2b Unlike the scenario in Fig. 2a ) is according to Fig. 2b ) only one vehicle with a baffle 4 with Aufkletterschutz worn 3 is provided.
  • the other vehicle has a conventional buffer whose impact body 4 'has a convexly curved impact surface 5'. Since the baffle 5 of the impact device 1 according to the invention is concave, that is curved inwardly, this corresponds in an optimal way with the convex curvature of the buffer 1 '. This causes in all three views in Fig. 2b ), so even with an offset of 40 mm, a vertical component of the impact force on the projections of the impact body 4 of the bumper 1 according to the invention can be added and removed to the support structure 6. The danger of climbing one vehicle to the other is also in this case, although only one vehicle with a Aufkletterschutz adopted is provided, significantly reduced or does not exist.
