    Ballistic protection arrangement for vehicles
    The invention relates to a ballistic protection arrangement for vehicles, in particular for running gears of rail vehicles with at least one first wheel set, which has a first wheel, a second wheel and a wheelset shaft.
    Components of vehicles, for example wheel set shafts of rolling stock for rail vehicles, must be protected against damage. Wheelshafts must be designed durable and high loads, especially on bending and torsion withstand.
    The design methods prescribed in the European Standards (EN), in particular in EN 13104 and EN 13103 as well as in the Russian Standards, in particular in OCT 32.93-97 apply only to non-corroded materials and undamaged surfaces. For this reason, axles must have corrosion protection and this and the wheelset itself must be protected against surface damage, which may be caused by, for example, stone chips, sand, snow and ice as well as exposure to high or low temperatures.
    If surface damage (such as notches) occurs, affected axles must be repaired, causing great maintenance and maintenance costs, as well as low vehicle availability.
    For example, the wheel set shaft protection arrangement Siemens Steel Rubber Axle Protection (SISRAP) is known from the prior art. SISRAP protects a wheel set shaft of a rail vehicle, e.g. before rockfall and includes a low temperature suitable elastomer mat, shells made of stainless steel sheet and mounting straps made of a stainless material.
    The elastomer mat has a thickness of 3 mm and encases a wheelset shaft, on which a corrosion protection coating is provided. The elastomer mat is in turn encased in two semi-cylindrical half-shells with thicknesses of 2mm each. Cross sections of the two half shells have the same radii.
    The wheel set shaft protection arrangement SISRAP is disclosed in DE 10 2010 009 437 A1.
    Said approach has in its known form the disadvantages of a large mass of Radsatzwellenschutzanordnung and a low suitability for speeds of the rail vehicle of greater than 250 km / h. The half shells would have to be designed for driving speeds of greater than 250 km / h in large thickness.
    Furthermore, the fastener tapes, in particular at speeds above 250 km / h in large numbers or have to be particularly thick or executed, whereby mass and inertia of the axle and increase the required drive power of the rail vehicle. In addition, this results in an increased space requirement in the wheelset shaft and an increased effort for assembly and disassembly of Radsatzwellenschutzanordnung.
    Furthermore, WO 00/59764 shows a Radsatzwellenschutz, which is designed as a cylindrical tube. The tube comprises a slot which extends over a lateral surface of the tube and facilitates assembly and disassembly operations.
    The tube may have two layers of different plastics. Furthermore, the tube can be designed in several parts. They are different
    Shutter devices shown, for example, two half-shells are connected to each other via screw connections or the tube has a hook closure.
    The invention has for its object to provide a comparison with the prior art further developed ballistic protection arrangement.
    According to the invention this object is achieved with a ballistic protection arrangement of the type mentioned, in which a shell which comprises at least a first layer of material having a first fiber material, is arranged around the wheelset shaft.
    The use of a first fiber material, which may comprise polyethylene fibers for example, causes a high energy absorption or attenuation of objects (eg basalt stones with a mass of up to 250 g), which at a vehicle speed of greater than 250 km / h hit the wheelset shaft. The wheel set is protected against deformation and other damage and an acoustic insulation is achieved.
    Furthermore, due to the first fiber material, the ballistic protection arrangement can be made with a small thickness and light, whereby a low mass and a low inertia of the wheelset shaft can be achieved.
    It is favorable if the shell has a second material layer.
    The second material layer can be made, for example, in steel,
    Titanium or in a fiber-reinforced plastic and be pressed with the first layer of material. The fiber-reinforced plastic may for example comprise a second fiber material with glass fibers and a matrix of organic material.
    Due to the second layer of material, a high tensile strength of the ballistic protection arrangement and thus an advantageous resistance to impacting objects (e.g., stones, etc.) is achieved.
    A composite of the first material layer and the second material layer may be thin and of low mass.
    An advantageous embodiment is obtained when the first material layer is designed as a fiber-reinforced plastic with the first fiber material and a second fiber material.
    By this measure, a ballistic protection arrangement with only one layer of material, but at the same time has a high energy absorption capacity, high tensile strength and a small thickness and mass achieved. For example, the first fibrous material may comprise polyethylene fibers blended with the second fibrous material, such as glass fibers and a matrix of organic material. This combines properties of high energy absorption capability and high tensile strength.
    A favorable solution is achieved if the shell has at least one zipper.
    This causes easy assembly and disassembly of the ballistic protection arrangement on the wheelset shaft.
    There are no tools required.
    Furthermore, the zipper compared to a hook closure or a screw connection has a small footprint and a low mass. In addition, no additional security locks (e.g., split pins) are required.
    The invention will be explained in more detail by means of exemplary embodiments.
    They show by way of example:
    1 shows a side elevation of a wheelset shaft in a sectional view with a first exemplary embodiment of a ballistic protection arrangement according to the invention, which has a first material layer and a second material layer,
    2 shows a side elevation of a wheel set shaft in a sectional view with a second exemplary embodiment of a ballistic protection arrangement according to the invention, which has exactly one first material layer,
    3 is an oblique view of a shell of a third exemplary embodiment of a ballistic protection arrangement according to the invention, which has a zipper,
    4 shows two side cracks of a wheelset shaft in a sectional view with the third exemplary embodiment of a ballistic protection arrangement according to the invention,
    Fig. 5: A plan view of a section of a
    Chassis with a first wheel, to the wheelset shaft, the third exemplary embodiment of a ballistic protection arrangement according to the invention is arranged, and
    Fig. 6: A plan view of a section of a
    Chassis with a first wheel, to the wheelset shaft a fourth exemplary embodiment of a ballistic protection arrangement according to the invention is arranged with a button closure.
    A side view of a wheel set shaft 4 of a rail vehicle shown in FIG. 1 with a first exemplary embodiment of a ballistic protection arrangement according to the invention comprises a cylindrical shell 5 which has an inner first material layer 6 and an outer second material layer 7.
    The wheelset shaft 4 has a corrosion protection coating, not shown.
    The shell 5 surrounds the axle 4 and is secured by a zipper 8.
    There are no or only negligible movements of the shell 5 relative to the axle 4 possible, i. the shell 5 is fixed on the axle 4.
    The first material layer 6 is pressed with the second material layer 7, wherein an unillustrated, known from the prior art autoclave is used for corresponding Verpressungsvorgänge.
    The first material layer 6 comprises a first fiber material having a fibrous web of synthetic fibers formed in polyethylene, whereby a high energy absorbing ability is achieved.
    The second material layer 7 is made of steel having a high tensile strength.
    Due to the first material layer 6 and the second material layer 7, properties of high energy absorption capability and high tensile strength are advantageously combined.
    According to the invention it is also conceivable to carry out the second material layer 7 in titanium or fiber-reinforced plastic. In a version in fiber-reinforced plastic, the fiber-reinforced plastic has a second fiber material made of glass fibers and a matrix of epoxy resin with flame retardant. However, other organic matrix materials, such as e.g.
    Polyurethane conceivable.
    The shell 5 has a thickness of 6 mm and is used for traveling speeds of the rail vehicle of up to 380 km / h.
    FIG. 2 shows a side elevation of a wheel set shaft 4 of a rail vehicle in a sectional view with a second exemplary embodiment of a ballistic protection arrangement according to the invention, wherein the ballistic protection arrangement comprises a cylindrical shell 5 with exactly one first material layer 6. The wheelset shaft 4 has a corrosion protection coating, not shown.
    The shell 5 surrounds the wheelset shaft 4 and is fixed by means of a zipper 8.
    The first material layer 6 is made of fiber-reinforced plastic. The fiber-reinforced plastic has a first fiber material of polyethylene fibers and a second fiber material of glass fibers. It is a matrix material made of epoxy resin with flame protection provided. However, other organic matrix materials, such as e.g. Polyurethane conceivable.
    The first fiber material is mixed with the second fiber material, whereby properties of a high fiber
    Energy absorption capacity and high tensile strength are combined with each other in an advantageous manner.
    3 shows a perspective view of a shell 5 of a third exemplary embodiment of a ballistic protection arrangement according to the invention with a zipper 8.
    The zipper 8 is arranged on a lateral surface of the cylindrical shell 5. It is rectilinear and aligned parallel to a Radsatzlängsachse 19.
    The zipper 8 is welded to the shell 5, which is made in a fiber-reinforced plastic. According to the invention it is also conceivable, for example, to weave the zipper 8 with the shell 5.
    Furthermore, it is also conceivable that the shell 5 comprises a first material layer 6 and a second material layer 7, the second material layer 7 is made in a metallic material and the zipper 8 is welded to the second material layer 7.
    The zipper 8 has a first staple row 9 and a second staple row 10 and a slider 11. With the slider 11, staples of the first staple row 9 and staples of the second staple row 10 can be hooked into one another and released again to close and open the tray 5. In a closed state of the zipper 8, the shell 5 is fixed on a wheel set shaft 4, not shown in FIG.
    In Fig. 4, a first state of a shell 5 of a third exemplary embodiment of a ballistic protection arrangement according to the invention with a zipper 8 is shown on the left and a second state on the right. The zipper 8 has a first staple row 9 and a second staple row 10.
    In the first state of the zipper 8 is opened and the shell 5 is bent and partially slipped over a wheelset shaft 4.
    In the second state, the shell 5 encases the wheelset shaft 4 and the zipper 8 is closed, i. the first staple row 9 and the second staple row 10 are interlocked.
    The shell 5 is fixed in the second state on the axle 4.
    The shell 5 has a first material layer 6 shown and described in FIG. 1 and a second material layer 7, the first material layer 6 having a first fiber material with a fiber fabric. The second material layer 7 is designed as a thin sheet steel. The ballistic protection arrangement is therefore made thin, light and flexible, whereby a small effort for assembly and disassembly, as shown in Fig. 4 left, the shell 5 is achieved.
    Fig. 5 shows a chassis of a rail vehicle with a chassis frame 13, a connected to the chassis frame 13 drive motor gear unit 14 and a first set of wheels 1 with a first wheel 2, a second wheel 3 and a wheelset 4. The first set of wheels 1 is a first wheelset bearing with a first Radsatzlagergehäuse 15 and a second Radsatzlager with a second Radsatzlagergehäuse 16 coupled to the chassis frame 13. Furthermore, a first primary spring 17 and a second primary spring 18 are arranged between the first wheel 1 and the chassis frame.
    The drive motor gear unit 14 is coupled to the first wheel set 1.
    In Fig. 5, not shown, a second set of wheels, the design and in terms of its coupling to the chassis frame 13 is the same as the first set of wheels 1 executed.
    On the wheel set shaft 4, a ballistic protection arrangement is arranged in a region between the drive motor gear unit 14 and the first wheel set bearing housing 15. This has a shell 5, which surrounds the axle 4. On the shell 5, as shown in Fig. 3 and Fig. 4, a zipper 8 is arranged. This is closed and the shell 5 is fixed on the axle 4.
    In Fig. 6, a chassis of a rail vehicle is shown, which corresponds in terms of constructive principles that suspension variant, which is shown in Fig. 5. In FIG. 6, therefore, the same reference numerals as in FIG. 5 are used in part.
    On a wheelset shaft 4, a ballistic protection arrangement is arranged in a region between a drive motor gear unit 14 and a first wheel set bearing housing 15. This has a shell 5, which surrounds the axle 4. On the shell 5, a button closure 12 is arranged.
    The button closure 12 has on one side of the shell 5 a Knopfreihe with snaps on another side of the shell 5, a series with recesses.
    The push buttons are locked in a state of mounting shown in Fig. 6 in the recesses. The button closure 12 is therefore closed and the shell 5 is fixed on the axle 4.
    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 elastic material. As a result, the shell 5 can be pushed onto it like a stocking after a production process of the wheelset shaft 4. The shell 5 abuts against the wheelset shaft 4 and is fixed on the axle 4.
    Furthermore, it is also possible to arrange a plurality of shells 5 on the wheelset shaft 4, for example, a first shell between the first Radsatzlagergehäuse 15 and a not shown in Fig. 1 to Fig. 6 first shaft brake disk and a second shell between the first shaft and a likewise disc not shown second shaft brake disc etc.
    Moreover, it is conceivable that the shell 5 comprises, for example, a first partial shell and a second partial shell, whose cross-sections have the same radii and which can be connected to one another via a first zipper and a second zipper.
