  • 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.
  • the axle protection arrangement SISRAP is in the DE 10 2010 009 437 A1 disclosed.
  • 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.
  • the half-shells would have to be thick.
  • 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.

  • objects e.g. basalt stones with a mass of up to 250 g
  • the wheelset is protected against deformation and other damage and acoustic insulation is achieved.
  • 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.
  • the shell has a second layer of 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.
  • a composite of the first material layer and the second material layer can be thin and have a low mass.
  • first material layer is designed as a fiber-reinforced plastic with the first fiber material and a second fiber material.
  • 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.
  • a favorable solution is achieved if the shell has at least one zipper.
  • the zipper has a low Space requirements and a low mass.
  • no additional locking devices e.g. cotter pins
