Definitions

• the invention relates to a stone impact protection device for protecting at least one arranged in the region of the underbody ei ⁇ nes rail vehicle vehicle component, in particular a wheel set shaft, with at least one elastic shielding member and at least one the shielding tra ⁇ constricting holding means.
• the invention is further based on a rail vehicle for a driving operation on track systems with ballasted track, which has at least one vehicle component and a rockfall protection arrangement in the region of its subfloor.
• 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.

• 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.

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.
