- the protection of axles for example, consists elas ⁇ -Nazi coatings with different materials, or even sheaths of the shafts with additional rubber-like materials.
- a disadvantage is that the thick coating makes the inspection of the surface of the shaft more difficult and thus also the maintenance of the rail vehicle.
- the invention has for its object to provide a rockfall protection arrangement and a rail vehicle with Steinschlag- protection arrangement, which easily and effectively avoids the damaging effect of whirled ballast stones or other foreign body, but allows a simple inspection.
- a plurality of elastic strips having formed as a flexurally ⁇ te shielding members are provided which are held by means of the least rich Minim ⁇ a holding means at their respective two Endbe-.
- Each of the bars held at their end regions ⁇ chen particularly well absorbed elas ⁇ shows the energy of a rock slide with their resilient bending midsection.
- the holder of the Leis- in / at the at least one holding device is to be understood in particular as a storage in the sense of a fixed storage and / or ei ⁇ nes movable bearing.
- Such a rockfall protection arrangement has the advantage that it can be assembled and disassembled relatively quickly and therefore makes it possible to inspect the at least one component to be protected.
- the flexurally elastic strips are preferred as of Federble ⁇ chen formed sheet metal strips, or as pultruded fiberglass slats (GFRP: glass fiber reinforced plastic) is formed.
- the rockfall protection arrangement can serve to protect one or more vehicle components in the region of the underbody of the rail vehicle.
- the rockfall protection arrangement is a rockfall protection arrangement for protecting a wheelset shaft of the rail vehicle.
- about ⁇ covers a flächi- ge shielding structure formed by the flexurally elastic strips the outer surface of the shaft (with the exception of narrow gaps between the ridges) is preferably in full.
- the longitudinal axes of the strips are preferably kept aligned parallel to one another.
- the at least one holding device is thus designed to keep the longitudinal axes of the strips parallel.
- a flat shielding structure can be formed in a simple manner, which covers / shields the at least one vehicle component.
- the stone chipping protection arrangement on a relatively homogeneous rigidity.
- two holding devices are provided, of which one holding device holds the respective one end region and the other holding device the respective other end region of each of the strips.
- the holding means are designed to allow a low-tension bending of the strips elastic and / or elastically connected to each other.
- the at least one holding device is a holding device for a spaced storage of the strips relative to the vehicle component to be protected.
- the distance a between the ridges and the surface of the component to be protected or the components to be protected is in accordance with the typically occurring kine ⁇ tables energy of the objects and the rigidity of the strips determined.
- at least one Sicke- is configured entspre ⁇ accordingly.
- the at least ei ⁇ ne holding device on the formed as Radsatzwelle vehicle component by means of at least one clamp, in particular ⁇ special a worm thread clamp is fastened.
- Such attachment of the stone impact protection arrangement for the wheel set shaft has the advantage that it is mon ⁇ animal and dismantled relatively rapidly and therefore an inspection of the least allows a minimum components to be protected. Retrofitting existing waves is possible without structural changes to the wheelset.
- the rockfall protection arrangement is an above-mentioned rockfall protection arrangement.
- the vehicle component to be protected is completely or at least partially covered by the rockfall protection arrangement.
- the vehicle component in the region of the vehicle underbody is in particular a wheelset shaft.
- the lateral surface of the wheelset shaft is of the totality of the strips
- Rockfall protection arrangement - each with a radial distance a - surrounded circumferentially.
- the strips have a corresponding vaulting on.
- the holding device or the Halteeinrich- lines is attached to the at least one vehicle to be protected ⁇ component ⁇ / are.
- the holding device or holding means can also be at least one other vehicle component, preferably a benachbar ⁇ th vehicle component to be fastened.
- the strips are held by the at least one holding device of the rockfall protection arrangement transversely to the direction of travel of the rail vehicle.
- Fig. 2 shows a rockfall protection arrangement for the protection of a
- FIG. 3 shows a sectional view through the rockfall protection arrangement and the wheelset shaft along the section line III - III of FIG. 2, and
- FIG. 4 shows a detailed illustration of the attachment of the rockfall protection arrangement to the shaft.
- 1 shows a schematic representation of the functional principle of a rockfall protection arrangement or a rockfall protection device 10 for protecting a vehicle component 12 of a rail vehicle, not shown.
- the vehicle component 12 of the rail vehicle to be protected is a wheel set shaft 14 of a wheel set of the rail vehicle in this example.
- the rockfall protection arrangement 10 consists of a plurality of designed as flexurally elastic strips 16 Abtranele ⁇ ments. These strips 16 are at their respective each other in the longitudinal extent of the respective bar 16 oppositely disposed two end portions 18, 20 mounted such that the flexurally elastic strips 16 in a central portion 22 in the direction of the component to be protected 12, so here radially in the direction of the shaft 14th , can bend. In this case, the end regions 18, 20 are held at a distance a spaced from the vehicle component 12. In the undeformed state, the strips 16 extend parallel to the axis of rotation 24 of the shaft 14.
- the strips 16 are formed, for example, as metal strips or metal strips of a spring plate or as pultruded fins made of GRP (GRP: glass fiber reinforced plastic).
- FIG. 2 shows a wheel set 30 with the wheelset shaft 14 and the two wheel disks 32, 34.
- the wheel set shaft 14 is surrounded by the rockfall protection arrangement 10 between the wheel disks 32, 34.
- This comprises the strips 16 and two annular holding devices 36, 38 which respectively hold one of the end regions 18, 20 of the strips 16 or store.
- FIG. 3 shows a sectional view through the vehicle component 12 to be protected formed as a wheel set shaft 14 and the rockfall protection arrangement 10 along the section line III-III shown in FIG.
- the strips 16 are circumferentially distributed at the same radial distance around the shaft 14 and its axis 24 around.
- a rockfall protection arrangement 10 is shown with six lamellar strips 16 but it can also less or more, for example, four or eight, strips 16 are used.
- the strips 16 continue to have a curvature. This curvature has the one hand, advantageous effect on the flexural strength of the strips 16, on the other hand results in a ⁇ a uniform distance a from the circumferential surface of the shaft fourteenth
- FIG. 4 is a detailed illustration of one of the holding devices 36 of the rockfall protection arrangement 10 and shows the attachment of this holding device 38 to the component 12 to be protected, namely the wheelset shaft 14 (area IV of FIG. 2).
- the other holding device 36 and its attachment are designed accordingly.
- the holding device 36, 38 for mounting / storage of the strips 16 is designed to be elastic within the protective device 10, so that a free bending of the strips 16 is possible.
- the holding device 36, 38 has a base 40 consisting of two parts (more precisely two half shells), a profile 42 also consisting of two parts and a clamp 44 designed as a screw thread clamp.
- the parts of the Ba ⁇ sis 40 are made of an elastic material, in particular egg ⁇ nem rubber-like material.
- the base 40 forms together with the base 40 circumferentially surrounding profile 42 receptacles for the end portions 18, 20 of the strips 16.
- the Tei ⁇ le of the profile 42 are optionally made of metallic materials or plastics.
- the connection of the holding device 36, 38 to the shaft 14 takes place in each case by the clamp 44, which is introduced into a shoulder of the profile 42, thereby being protected against gravel flight itself.
