Definitions

  • the invention relates to a head structure for connection to the base plate of the wagon body structure of a railway vehicle; to form the body shell structure of the rail vehicle.
  • head structures for rail vehicles are embodied as a welded part. Structures have also been implemented in which plates or profile structures which are screwed underneath form the main transverse beam - sometimes even one or two central longitudinal beams - or form the coupling plate. They are prefabricated as one large assembly comprising sectional structures and are then connected to the base plate by means of screwed attachment lines.
  • Such welded structures are highly complex welded assemblies because there is a multiplicity of force application points in the region of the head structure and to pass on the forces induced there in an optimized structural fashion requires supporting structures to be formed in a multiplicity of different directions of action and within different planes of action. This requires an extremely high fabrication expenditure as each discrete element of the supporting structure has to be welded on individually.
  • these elements are additionally composed of normal semi-finished products or individually formed extrusion profiles, there is a significant disadvantage that, owing to their prismatic structure, they have the same cross section over their entire length, which cross section has to be configured in accordance with the maximum stress occurring - which is possibly very limited locally.
  • greatly reduced residual strength properties have to be allowed for in the region of the weld seams.
  • a cast steel main frame for a locomotive formed by a single casting including bolsters, end frame members and a centre supporting member is known from US 1 659 361 .
  • the object of the invention is thus to provide a structure which is easy to manufacture, optimized in terms of weight and comparatively easy to mount for the body shell structure of the base group of a rail vehicle. This object is achieved according to the invention if the head structure of the base group is fabricated as a large light alloy cast part, in accordance with Claim 1.
  • the inventors have surprisingly not only detected that, counter to the previous assumption and practice, such a complex construction of a respective head structure for the body shell of the base group of a rail vehicle can advantageously be manufactured as a light alloy cast part, but according to the invention they also propose doing this using conventional light alloy casting methods.
  • the light alloy cast part which is produced and mechanically finished in an optimum way in terms of propagating technology in the regions of mechanical interfaces in order to connect the draw and buffer equipment and the interfaces with the bogey, including the support points of the wagon body in an optimized way in terms of fabrication technology, is integrated into the rest of the wagon body shell according to the invention optionally by means of welding, screwing, riveting, connection by bolts, bonding or compatible combinations of these methods.
  • the essential advantages of the invention over the prior art are the comparatively low fabrication expenditure, even with complex cast parts.
  • the manufacture and processing can be automated to a much greater extent than the manufacture and processing of welded structures.
  • the head structure which is manufactured according to the invention hardly has any thermal warping and requires only a small amount of post-processing.
  • the wall thicknesses can be adapted to the local variable necessary cross-sectional requirements with relatively little expenditure by simply changing the cast shape. It is particularly advantageous here that the invention provides the possibility of connecting the part to the rest of the wagon body structure by bonding owing to the large surfaces of the interfaces, despite the very high forces which are applied to the large cast part.
  • the head structure according to the invention is designated in its entirety by 1. It has essentially a base plate 2, a head plate 3, a longitudinal support 4 and one or more local reinforcing elements 5.
  • a main transverse beam 6 is provided adjoining the base plate 2, the head structure according to the invention being connected by means of said main transverse beam 6 to the base plate 7 of a wagon body of a rail vehicle. This connection can be made, as mentioned at the beginning, for example by means of welding, screwing, riveting, connection by bolts, bonding or the like.
  • the head structure according to the invention is defined in that it is fabricated in its entirety of a large cast part made of light alloy, for example an aluminium alloy.
  • the base plate 2 of the head structure 1 can be bonded here over a large area, possibly the entire area, to a wagon body-mounted base plate in a thick bed method by means of an adhesive with defined oscillation-damping properties.
  • it acts on the wagon body as a novel tertiary spring stage.
  • each individual screw connection or retaining ring bolt connection being configured such that it also clamps a cushion which is composed of a metal mesh and which has defined oscillation-damping properties and thus acts on the wagon body as a tertiary spring stage.
