Definitions

  • the invention relates to a rail vehicle with a component to be protected against ballast, such as a bottom flap, with a baffle plate, which is arranged on an outer side of the component.

  • the baffle plate a composite of stacked, woven and with a Tough elastic material as binders interconnected mats made of solid plastic fibers or glass fibers has.
  • Such a composite of solid plastic fibers (Kevlar) or glass fibers has the advantage that the baffle plate has a compliance, whereby they are when charged with
  • the mat composite acts in a similar manner to a tennis racket, i. An impinging scotch deflects the matting from a flat position, then swings back and carries the ballast in a direction away from the component to be protected.
  • a binder for the mat composite is preferably a thermoplastic used, which is characterized by a high toughness.
  • the baffle plate can be constructed in a simple embodiment exclusively from the composite of the mats.
  • the baffle plate may be formed as a sandwich plate having a core layer, on one side of which
  • Mats composite are attached.
  • the core layer has a stiffness that is so pronounced that the flapper acts in a similar manner to the fabric of a tennis racket.
  • the core layer ensures a lower overall thickness.
  • Such a sandwich panel is characterized by a high availability under reliable ballast protection.
  • superficial damage can be easily repaired by subsequent application of, for example, thermoplastic. the.
  • thermal loads can be recycled with low energy consumption.
  • the materials that make up the panels are light-weight fabrics that have a lower density compared to traditional solutions, which opens up the possibility of reducing weight and reducing energy consumption.
  • the structure of the sandwich panel can be adapted to particular applications. Thus, their properties can be varied and optimized by the mat construction of individual layers and the thickness of the mat, the number of layers, and in particular the stiffness and elasticity of the sandwich panel. It is possible to absorb large impact forces in the way of lightweight construction.
  • the two mat composites may be bonded together with the core layer by thermoplastic material or tough elastic adhesive. It is particularly possible that the baffle plate is made in a single process step of the superposed mats and the core layer using a viscoelastic binder.
  • the core layer may preferably be formed by a (tough) elastic honeycomb or rigid foam structure.
  • Honeycomb known honeycomb structure may be metallic, for example.
  • the baffle plate is arranged such that one of the mat composites facing the component and the other mat composite is directed outwards, wherein the outwardly facing mat composite has a higher layer thickness than the component facing mat composite.
  • the outer mat composite layer is thus thicker than the inner, to ensure better protection against ballast.
  • the values for the entire thickness of the baffle plate as well as those for the inner and the outer has a thickness in the range of 10 mm - 30 mm, the component facing mat composite has a thickness of 1 mm - 5 mm and the outwardly facing mat composite has a thickness in the range of 1.5 mm - 10 mm, in particular Baffle plate has a thickness in the range of 15mm - 25mm, the component facing mat composite has a thickness of 1mm - 3mm and the outwardly facing mat composite has a thickness in the range of 2mm - 6mm.
