Definitions

  • Rail vehicle with a device for the protection of passers-by and a device for the protection of passers-by
  • the invention relates to a rail vehicle with a device for the protection of pedestrians in the event of a collision with the vehicle front of the vehicle according to the preamble of claim 1, as well as a device for pedestrian protection for use
  • Rail vehicles such as Low or medium-floor trams or light rail vehicles, usually run in mixed driving. This means that they represent participants in public transport and thus interact with people as road users.
  • an obstacle of appropriate size e.g. represents a person lying in front of the vehicle, on a directly at the beginning of the gap on the vehicle front hanging vertically hangs structure.
  • This structure is designed to hinder obstacles to a certain extent. However, if an obstacle is such that it can not be pushed further either for reasons of too great mass or too much friction against the direction of travel, this structure allows another structure to be folded down from the underbody onto the roadway before the first one threatens to break. In this case, this second down-folding structure forms a "ramp" immediately in front of the first chassis, so that in case of breaking through the
  • a disadvantage of these protective systems is therefore that the majority of vehicle types using them are high or medium floor vehicles, which are usually equipped with a suitable ground clearance. Another disadvantage is that it can come to sharp-edged deformations or fractures of the existing protective structures, if they can not support the burden of the "person to be pushed".
  • Protective structure is not "carrying” executed.
  • these first structures or brackets are already at a significant distance from the front of the vehicle. On the one hand, this means that an overridden person must have already gotten far enough under the vehicle before coming into contact with the first structure.
  • this structure is not designed to push the person further in front of him, but merely to let down the final "catching structure".
  • the invention includes a rail vehicle with a device or a
  • the respective structure can not only open, but also represent a closed body.
  • the structures may consist of metallic materials.
  • the structure consists of a welded, flexible double plate which can be inflated by internal pressure deformation via a feed line or a gas generator connected directly to the structure with a gas medium.
  • the metal structure can be changed either by choosing the wall thickness or substituting it with other flexible metal structures.
  • the invention describes a selected embodiment of the inflatable structure as a closed welded metallic double board with a small wall thickness. This choice represents only one of the possible combinations of the invention and is not limited to this selection.
  • a special metallic diaphragm material is to be used, which consists primarily of a metallic, fine-meshed wire mesh.
  • the structure has flexible, inflatable, crack-resistant and contact-resistant properties.
  • the structure may consist of a metallic membrane material, which has a meshed wire structure, wherein the meshed wire structure can be formed in one or more layers.
  • the meshed wire structure has inner and / or outer protective layers of elastic materials.
  • the structure is laminated from the inside with an elastic film, which reduces or completely prevents the gas outlet. For very close-meshed network structures, this inner film, depending on the required
  • the inflation of the metal structure is triggered by a sensor, which is arranged on the vehicle front.
  • the sensor system is provided with measuring means which detect and / or detect the frontal impact of a person on the vehicle front.
  • the metal structure in the activated state forms a geometrieadaptiven shaped body, which fills the cavity between the vehicle body and the rail.
  • the inflation of the metal structure is advantageously carried out with a corresponding expansion speed, which prevents the risk of pulling a person under the vehicle.
  • the invention combines the basic principle of the complete "rejection" from the danger zone of a person in front of the vehicle by using a
  • the invention prevents both the retraction / driving over an unexpected and immediately before the vehicle front on the driveway coming to rest person in the nominal gap on the front of the vehicle, as well as any further risk of rolling over the rail wheels.
  • the closed metal structure may remain under the vehicle as it adapts to changing ground clearance.
  • the present invention can be integrated in all rail vehicles with front panel. It is basically irrelevant, whether it is low-floor, mid-floor or high-floor vehicles.
  • the protection system according to the invention can be installed in all new rail vehicles and also in all in use

  • FIG. 5a-5c show schematically the structure of the inflatable structure, in Fig. 5b with only a single-layered structure (5b) and with an additional optional tear-resistant layer (5c),
  • FIGS. 6a-c show various forms of formation of the structure in FIG.
  • the device 4 consists of at least one structure 7, which is inflatable by means of a gas medium 6 in order to survive in that dimensionally stable form in which the vehicle can be brought to a standstill.
  • the risk of injury is to be significantly reduced by filling the cavity between rail vehicle 1 and ground 3 immediately before or after the collision by the device 4 mounted on the underside of the rail vehicle front such that the person 2 involved in the collision does not can fall under the rail vehicle 1 and preferably in addition to the
  • a structure material selection of the device according to the invention is based on a structure 7, pronounced as a metal structure, namely on a thin sheet structure, which is expanded or inflated by a gas medium 6 introduced via feed lines 11 (different inflator states 8, 9, FIGS. 3 and 4) ).
  • the structure can also be connected directly to a gas generator (not shown). It is advantageous that the flexibility of the metal structure can be set by the wall thickness and this structure can be in the form of "tailored blank" in the form of welded double plates, whereby alternative, softer metal materials are also conceivable.
  • the device is triggered by a sensor system 10, which is adapted to the rail vehicle front and which detects the frontal impact of a person 2 or predicts the impact by optical, mechanical or other measurement principles is with respect to the
  • Expansions are designed so that the complete final geometry of the molding is already reached before the risk of "pulling in” of the person arises. These are usually a few milliseconds.
  • the structure must have flexible, inflatable, crack-resistant and contact-resistant properties.
  • a special metallic diaphragm material is to be used, which consists primarily of a metallic, fine-meshed wire mesh.
  • the meshed wire structure 12 may be single-layered or multi-layered and have inner and / or outer layers of elastic materials.
  • the structure can be laminated from the inside with an elastic film 13, which reduces or completely prevents the gas outlet. At very low pressure
  • FIGS. 5a to 5c schematically show the structure of the inflatable structure 7.

  • Mesh density the structure of the wire mesh (mesh density, Wire diameter, weave pattern) is case-specific too
  • the nets can also be annealed after weaving.
  • the structure can also be annealed after weaving.
  • planar wire nets are placed one on top of the other and joined together (FIG. 6a), toric wire nets are joined at both ends (FIG. 6b)
  • the rail vehicle 1 comprises a device (deflector obstacle deflector), which is upstream of the shock absorption system of the vehicle and which does not respond without triggering by an activation device. This should be the full
  • the triggering of the deflector obstacle deflector is either by the driver by means of a device on the driver's desk or by the automatic
  • Detection technology (not content of this invention) of the integrated in advance of the rail vehicle detection device.
  • the first response of one of these devices triggers the deflector obstacle deflector.
  • a gas generator inflates the closed metal structure, which lies folded in the starting position.
  • an additional deflecting movement is performed during inflation and deployment in the direction of the travel path, which moves the person (s) who are being driven over, so to speak under the vehicle.
  • This requires a coordination of the geometry of the closed metal structure to the relationships between the front panel and the track.
  • the closed, folded attached metal structure can also be designed in several parts to compensate for particular curvatures of the shock bar.
  • metal structure can rather be adapted to changing vertical space conditions such as e.g. to adapt to a reduction in nominal ground clearance between bumper and track: it is quite simple by the weight of the vehicle
  • the present invention is intended to supplement the parallel action for the protection of persons with regard to overrunning: the timely stopping of the override
