Definitions

  • the invention relates to a chassis of a chassis module for low-floor rail vehicles with the features according to the preamble of claim 1.
  • a chassis module for low-floor rail vehicles with the features according to the preamble of claim 1.
  • Such a base is by the FR-A-2604676 known.
  • Aluminum weldments in particular, must take into account strength losses in the area of the welds, either by reducing the allowable stresses or by increasing the wall thickness resulting in a weight increase.
  • car bodies designed as a welded construction are very cost-intensive and particularly susceptible to fatigue strength in the area of the weld seams, especially at high loads.
  • the invention has for its object to form a base of the generic type with elimination of the aforementioned disadvantages in the simplest possible and cost-wise ago manner so that, above all, a high dimensional accuracy and a strength adapted to the stresses at low weight can be achieved.
  • the Fig. 1 and 2 show each differently designed bases of a low-floor chassis module in perspective view.
  • a bottom plate 1 of a base frame on a central floor panel part 1 a which is arranged horizontally.
  • To the bottom plate 1 further includes two adjacent to the bottom plate part 1a, downwardly inclined ramp sheet parts 1b.
  • side walls 2 With the central base plate part 1a and the ramp sheet metal parts 1b side walls 2 are connected, which extend in the vehicle longitudinal direction and make wheel arches for wheels of a landing gear.
  • the lateral walls 2 each have a bevel 2a made at edges on their end section facing the bottom sheet metal part 1a and the ramp sheet metal parts 1b.
  • the underframe has two identically designed fork profiles as end cross member 3, which are welded using moldings 4 with the ramp sheet metal parts 1b of the bottom plate 1 and the side walls 2. Of the four fittings 4 in the drawing plane diagonally opposite fittings 4 are identical.
  • the central floor panel part 1a and the two ramp sheet parts 1b of the floor panel 1 and the side walls 2 are an assembly made entirely by U-shaped edges of a single sheet.
  • the downwardly inclined course of the ramp sheet metal parts 1b is created by further forming.
  • Fig. 2 It can be seen that the central base plate part 1a and the two ramp sheet parts 1b of the base plate 1 and the lateral walls 2 are each one of a total of three in the longitudinal direction of the underframe arranged behind one another assemblies. Each of these assemblies is generated by edges of a corresponding sheet.
  • the two outer modules are identical.
  • the undercarriage according to the invention is characterized by a cost-effective design, a high dimensional accuracy and a stress adapted strength. These advantages are achieved in particular by the reduction of components and welded joints, which are arranged anyway outside of the high voltage areas.
