Description

Die Erfindung betrifft eine ballistische Schutzanordnung für Fahrzeuge, insbesondere für Fahrwerke von Schienenfahrzeugen mit zumindest einem ersten Radsatz, der ein erstes Rad, ein zweites Rad und eine Radsatzwelle aufweist.The invention relates to a ballistic protection arrangement for vehicles, in particular for undercarriages of rail vehicles with at least one first wheel set, which has a first wheel, a second wheel and a wheel set axle.

Komponenten von Fahrzeugen, beispielsweise Radsatzwellen von Fahrwerken für Schienenfahrzeuge, müssen vor Schäden geschützt sein. Radsatzwellen müssen dauerfest ausgelegt sein und hohen Belastungen, insbesondere auf Biegung und Torsion, standhalten.Vehicle components, such as wheelset axles of bogies for rail vehicles, must be protected against damage. Wheelset axles must be designed to be durable and withstand high loads, especially bending and torsion.

Die in den Europäischen Normen (EN), insbesondere in der EN 13104 und der EN 13103 sowie in den russischen Normen, insbesondere in der OCT 32.93-97 vorgeschriebenen Auslegungsmethoden gelten nur für nicht-korrodierte Werkstoffe und unbeschädigte Oberflächen. Aus diesem Grund müssen Radsatzwellen einen Korrosionsschutz aufweisen und dieser sowie die Radsatzwellen selbst müssen vor Oberflächenschäden, die beispielsweise von Steinschlag, Sand, Schnee und Eis sowie einer Einwirkung hoher oder tiefer Temperaturen verursacht werden können, geschützt sein.The design methods prescribed in the European standards (EN), in particular in EN 13104 and EN 13103 and in the Russian standards, in particular in OCT 32.93-97, only apply to non-corroded materials and undamaged surfaces. For this reason, wheelset axles must have corrosion protection and this, as well as the wheelset axles themselves, must be protected against surface damage that can be caused, for example, by stone chips, sand, snow and ice as well as the effects of high or low temperatures.

Treten Oberflächenschäden (z.B. Kerben) auf, müssen betroffene Radsatzwellen repariert werden, wodurch ein großer Instandhaltungsaufwand und hohe Instandhaltungskosten sowie eine geringe Verfügbarkeit der Fahrzeuge verursacht werden.If surface damage (e.g. notches) occurs, the wheelset shafts affected must be repaired, which results in a large amount of maintenance work and high maintenance costs as well as low vehicle availability.

Aus dem Stand der Technik ist beispielsweise die Radsatzwellenschutzanordnung Siemens Steel Rubber Axle Protection (SISRAP) bekannt. SISRAP schützt eine Radsatzwelle eines Schienenfahrzeugs z.B. vor Steinschlägen und umfasst eine tieftemperaturtaugliche Elastomermatte, Halbschalen aus nichtrostendem Stahlblech sowie Befestigungsbänder aus einem nichtrostenden Material.The Siemens Steel Rubber Axle Protection (SISRAP) axle protection arrangement, for example, is known from the prior art. SISRAP protects a wheel set axle of a rail vehicle against stone chipping, for example, and includes an elastomer mat that is suitable for low temperatures, half-shells made of stainless sheet steel and fastening straps made of a non-rusting material.

Die Elastomermatte weist eine Dicke von 3mm auf und ummantelt eine Radsatzwelle, auf der eine Korrosionsschutzbeschichtung vorgesehen ist. Die Elastomermatte ist wiederum von zwei halbzylindrischen Halbschalen mit Dicken von je 2mm ummantelt. Querschnitte der beiden Halbschalen weisen gleiche Radien auf.The elastomer mat has a thickness of 3mm and encases a wheelset axle with an anti-corrosion coating is provided. The elastomer mat is in turn encased by two semi-cylindrical half-shells, each 2mm thick. Cross sections of the two half-shells have the same radii.

Die Radsatzwellenschutzanordnung SISRAP ist in der DE 10 2010 009 437 A1 offenbart.The axle protection arrangement SISRAP is in the DE 10 2010 009 437 A1 disclosed.

Der genannte Ansatz weist in seiner bekannten Form die Nachteile einer großen Masse der Radsatzwellenschutzanordnung sowie einer geringen Tauglichkeit für Fahrgeschwindigkeiten des Schienenfahrzeugs von größer als 250 km/h auf. Die Halbschalen müssten für Fahrgeschwindigkeiten von größer als 250 km/h in großer Dicke ausgeführt sein.In its known form, the mentioned approach has the disadvantages of a large mass of the wheel set shaft protection arrangement and a low suitability for rail vehicle travel speeds of more than 250 km/h. For driving speeds of more than 250 km/h, the half-shells would have to be thick.

Weiterhin müssen die Befestigungsbänder insbesondere bei Geschwindigkeiten über 250 km/h in großer Anzahl oder besonders dick oder ausgeführt werden, wodurch Masse und Trägheit der Radsatzwelle sowie erforderliche Antriebsleistungen des Schienenfahrzeugs steigen. Darüber hinaus ergeben sich dadurch ein erhöhter Platzbedarf im Bereich der Radsatzwelle sowie ein vergrößerter Aufwand für eine Montage und Demontage der Radsatzwellenschutzanordnung.Furthermore, the fastening straps have to be large in number or particularly thick, especially at speeds of over 250 km/h, which increases the mass and inertia of the wheelset shaft and the required drive power of the rail vehicle. In addition, this results in an increased space requirement in the area of the wheel set shaft and increased effort for assembly and disassembly of the wheel set shaft protection arrangement.

Weiterhin zeigt die WO 00/59764 einen Radsatzwellenschutz, welcher als zylindrisches Rohr ausgebildet ist. Das Rohr umfasst einen Schlitz, der sich über eine Mantelfläche des Rohrs erstreckt und Montage- und Demontagevorgänge erleichtert.Furthermore, the WO 00/59764 a wheelset shaft protection, which is designed as a cylindrical tube. The tube includes a slot that extends across an envelope surface of the tube and facilitates assembly and disassembly operations.

Das Rohr kann zwei Schichten aus unterschiedlichen Kunststoffen aufweisen. Weiterhin kann das Rohr mehrteilig ausgebildet sein. Es sind unterschiedliche Verschlussvorrichtungen dargestellt, wobei beispielsweise zwei Halbschalen über Schraubenverbindungen miteinander verbunden sind oder das Rohr einen Hakenverschluss aufweist.The tube can have two layers of different plastics. Furthermore, the pipe can be made in several parts. Different closure devices are shown, with two half-shells being connected to one another via screw connections, for example, or the tube having a hook closure.

Ferner zeigt die DE 20 2014 008 476 U1 eine röhrenförmige Schlagschutzvorrichtung, welche zwei Halbschalen und trichterförmige Endabschnitte aufweist. Es ist eine Trägerschicht aus Metall oder kohlefaserverstärktem Kunststoff vorgesehen, mit welcher Elastomer oder mit Elastomer durchsetztes Gewebe verbunden ist.Furthermore, the DE 20 2014 008 476 U1 a tubular impact protection device which has two half-shells and funnel-shaped end portions. It is one Support layer made of metal or carbon fiber reinforced plastic is provided, with which elastomer or fabric impregnated with elastomer is connected.

Die EP 1 942 040 A1 offenbart einen Schutzmantel für eine Radsatzwelle eines Schienenfahrzeugs, bei der eine äußere Abschirmschicht und eine innere Dämpfungsschicht vorgesehen sind. Die äußere Schicht ist mit einem metallischen Film ummantelt und es kann mit ihr eine Verschlussvorrichtung verbunden sein.The EP 1 942 040 A1 discloses a protective casing for an axle of a rail vehicle, in which an outer shielding layer and an inner damping layer are provided. The outer layer is covered with a metallic film and may have a closure device associated therewith.

Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber dem Stand der Technik weiterentwickelte ballistische Schutzanordnung anzugeben.The invention is based on the object of specifying a ballistic protection arrangement that is further developed than in the prior art.

Erfindungsgemäß wird diese Aufgabe gelöst mit einer ballistischen Schutzanordnung mit den technischen Merkmalen des Anspruchs 1.According to the invention, this object is achieved with a ballistic protection arrangement having the technical features of claim 1.

Der Einsatz eines ersten Faserwerkstoffs, der beispielsweise Polyethylen-Fasern aufweisen kann, bewirkt eine hohe Energieabsorption bzw. Dämpfung bei Objekten (z.B. Basaltsteine mit einer Masse von bis zu 250 g), die bei einer Fahrgeschwindigkeit des Fahrzeugs von größer als 250 km/h auf die Radsatzwelle auftreffen. Der Radsatz ist gegen Deformationen und sonstige Schäden geschützt und es wird eine akustische Dämmung erzielt.The use of a first fiber material, which can have polyethylene fibers, for example, causes a high level of energy absorption or damping in objects (e.g. basalt stones with a mass of up to 250 g) that occur at a vehicle speed of more than 250 km/h strike the wheelset shaft. The wheelset is protected against deformation and other damage and acoustic insulation is achieved.

Weiterhin kann die ballistische Schutzanordnung aufgrund des ersten Faserwerkstoffs mit geringer Dicke und leicht ausgeführt sein, wodurch eine geringe Masse und eine geringe Trägheit der Radsatzwelle erzielt werden.Furthermore, due to the first fiber material, the ballistic protection arrangement can be designed with a small thickness and light weight, as a result of which a low mass and low inertia of the wheelset axle are achieved.

Es ist erfindungsgemäß vorgesehen, dass die Schale eine zweite Materialschicht aufweist.It is provided according to the invention that the shell has a second layer of material.

Die zweite Materialschicht kann beispielsweise in Stahl, Titan oder in einem faserverstärkten Kunststoff ausgeführt und mit der ersten Materialschicht verpresst sein. Der faserverstärkte Kunststoff kann beispielsweise einen zweiten Faserwerkstoff mit Glasfasern aufweisen sowie eine Matrix aus organischem Material.The second layer of material can be made of steel, titanium or a fiber-reinforced plastic, for example, and pressed with the first layer of material. The fiber-reinforced plastic can have, for example, a second fiber material with glass fibers and a matrix made of organic material.

Aufgrund der zweiten Materialschicht wird eine hohe Zugfestigkeit der ballistischen Schutzanordnung und somit eine vorteilhafte Resistenz gegen auftreffende Objekte (z.B. Steine etc.) erzielt.Due to the second material layer, a high tensile strength of the ballistic protection arrangement and thus an advantageous resistance to impacting objects (e.g. stones, etc.) is achieved.

Ein Verbund aus der ersten Materialschicht und der zweiten Materialschicht kann dünn und mit geringer Masse ausgeführt sein.A composite of the first material layer and the second material layer can be thin and have a low mass.

Eine alternative, jedoch nicht beanspruchte, Ausgestaltung erhält man, wenn die erste Materialschicht als faserverstärkter Kunststoff mit dem ersten Faserwerkstoff und einem zweiten Faserwerkstoff ausgeführt ist.An alternative, but not claimed, configuration is obtained when the first material layer is designed as a fiber-reinforced plastic with the first fiber material and a second fiber material.

Durch diese Maßnahme wird eine ballistische Schutzanordnung mit nur einer Materialschicht, die jedoch zugleich eine hohe Energieabsorptionsfähigkeit, eine hohe Zugfestigkeit sowie eine geringe Dicke und Masse aufweist, erzielt. Der erste Faserwerkstoff kann beispielsweise Polyethylen-Fasern aufweisen, die mit dem zweiten Faserwerkstoff, beispielsweise mit Glasfasern und einer Matrix aus organischem Material, vermengt sind. Dadurch werden Eigenschaften einer hohen Energieabsorptionsfähigkeit und einer hohen Zugfestigkeit kombiniert.This measure achieves a ballistic protection arrangement with only one layer of material, which, however, at the same time has a high energy absorption capacity, a high tensile strength and a low thickness and mass. The first fiber material can, for example, have polyethylene fibers which are mixed with the second fiber material, for example glass fibers and a matrix made of organic material. This combines properties of high energy absorbency and high tensile strength.

Eine günstige Lösung wird erzielt, wenn die Schale zumindest einen Reißverschluss aufweist.A favorable solution is achieved if the shell has at least one zipper.

Dadurch wird eine leichte Montier- und Demontierbarkeit der ballistischen Schutzanordnung auf der Radsatzwelle bewirkt. Es sind keine Werkzeuge erforderlich.This makes it easy to assemble and disassemble the ballistic protection arrangement on the axle. No tools are required.

Weiterhin weist der Reißverschluss im Vergleich zu einem Hakenverschluss oder einer Schraubenverbindung einen geringen Platzbedarf sowie eine geringe Masse auf. Es sind außerdem keine zusätzlichen Verschlusssicherungen (z.B. Splinte) erforderlich.Furthermore, compared to a hook fastener or a screw connection, the zipper has a low Space requirements and a low mass. In addition, no additional locking devices (e.g. cotter pins) are required.

Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen näher erläutert.The invention is explained in more detail below using exemplary embodiments.

The button closure 12 is therefore closed and the shell 5 is fixed on the wheel set axle 4 .

Erfindungsgemäß ist es auch denkbar, auf einen Verschluss auf der Schale 5 zu verzichten und beispielsweise die Schale 5 aus einem besonders dehnbaren Material zu fertigen. Dadurch kann die Schale 5 ähnlich einem Strumpf nach einem Fertigungsvorgang der Radsatzwelle 4 auf diese geschoben werden. Die Schale 5 legt sich an die Radsatzwelle 4 an und ist auf der Radsatzwelle 4 fixiert.According to the invention, it is also conceivable to dispense with a closure on the shell 5 and, for example, to manufacture the shell 5 from a particularly stretchable material. As a result, the shell 5 can be slid onto the wheelset shaft 4 in a manner similar to a stocking after a manufacturing process. The shell 5 rests against the wheel set shaft 4 and is fixed on the wheel set shaft 4 .

Weiterhin ist es auch möglich, mehrere Schalen 5 auf der Radsatzwelle 4 anzuordnen, beispielsweise eine erste Schale zwischen dem ersten Radsatzlagergehäuse 15 und einer in Fig. 1 bis Fig. 6 nicht dargestellten ersten Wellenbremsscheibe und eine zweite Schale zwischen der ersten Wellenbremsscheibe und einer ebenfalls nicht gezeigten zweiten Wellenbremsscheibe etc.Furthermore, it is also possible to arrange several shells 5 on the axle 4, for example a first shell between the first axle box 15 and an in Figures 1 to 6 first wave brake disc, not shown, and a second shell between the first wave brake disc and a second wave brake disc, also not shown, etc.

Darüber hinaus ist es denkbar, dass die Schale 5 beispielsweise eine erste Teilschale und eine zweite Teilschale umfasst, deren Querschnitte gleiche Radien aufweisen und die über einen ersten Reißverschluss und einen zweiten Reißverschluss miteinander verbunden werden können.In addition, it is conceivable that the shell 5 comprises, for example, a first partial shell and a second partial shell, the cross sections of which have the same radii and which can be connected to one another via a first zipper and a second zipper.
