Definitions
- the invention relates to a bogie frame for a rail vehicle, comprising two as open or
- Longitudinal member is formed by wall elements which have a certain thickness.
- the invention is both on bogie frame with
- Bogie frame manufactured with high material and manufacturing costs This results in high technical costs as well as high costs
- the production of a weld seam counterpart on the side of the weld root is no longer possible due to lack of accessibility, and therefore the weld seam can not be loaded with the same forces as a counterstay.
- the sheet thicknesses must be increased in order to make the welds in a row thicker and therefore stronger.
- the side rail can be made with a lid, whereby it is possible to weld the welds inside.
- a disadvantage of the method is a significantly increased production costs due to the longer welding time, increased manipulation effort and additionally required
- Hollow profile of the longitudinal member is formed by wall elements, which have a certain thickness, to provide, which has less weight compared to the known bogie frame described above or a lower manufacturing cost and thus lower
- the invention provides that the longitudinal members in the region of the fastening of the at least one cross member each have a wall element with at least one region of reduced thickness.
- the reduced thickness can be realized by the wall element has a cutout at said location.
- a wall element only have a continuous region with reduced thickness.
- a wall panel could also have several separate areas of reduced thickness
- the wall elements have a constant thickness, so that in the region of reduced thickness, the wall element has a reduced thickness in comparison with the rest
- the thickness is constant except for an edge region, wherein the edge region as a transition from the thickness of the remaining wall element to the thickness of the
- Has region of reduced thickness a chamfer.
- Wall element in the region of reduced thickness is not more than 90% of the thickness of the wall element outside the region of reduced thickness, preferably in the range of 10-90%, in particular in the range of 30-70%.
- Cross member is understood to be the section of the longitudinal member on which the cross member attacks, as well as the part thereof
- part of the longitudinal member immediately surrounding this section that is, for example, the part of the longitudinal member which is closer to the cross member than the ends of the longitudinal member, the middle of the longitudinal member or another cross member.
- the area of reduced thickness reduces deformation in the area of the weld seams and thus reduces stress in the welds. This means that the weight can be reduced and no lids are needed, whereby the manufacturing cost decreases.
- the side members each have on a side facing the at least one cross member a wall formed as an internal web wall element with an inside, on which inside
- At least one area of reduced thickness is provided. It is thus at the location of the connection of the cross member, the thickness on the side facing away from the cross member of the
- reduced internal web which particularly reduces the deformation in the area of those welds that are closest to the area of reduced thickness.

- longitudinal members each comprise at least one connecting element, which serves as a connection for the at least one
- Cross member serves and which has at least one wall element with a region of reduced thickness
- connection element refers to the element which is located between the cross member and the remaining longitudinal member and which forms the connection for the cross member.
- box profile refers to a closed hollow profile
- the wall elements must be aligned parallel to another wall element and the wall elements may also have curvatures.
- the connecting webs, as well as the upper flange and the lower flange at the surfaces forms planes which are parallel to the longitudinal axis of the cross member.

- the area of reduced thickness is thus centrally located in the
- the at least one region of reduced thickness is located on an outside of the at least one region of reduced thickness
- the region with reduced thickness is usually produced on the individual part, that is to say on the individual wall element, in particular milled out (and then the individual parts are first welded together).
- the area with reduced thickness is produced on the same side as the weld bevel, whereby a re-clamping of the
- Wall element between the production of the area with reduced thickness and the weld chamfers can be omitted.
- the shape of the region of reduced thickness - as seen in the plane of the wall element - will also usually be substantially rectangular.
- One embodiment of the bogie frame provides that in the connection element the area of reduced thickness corresponds to 20-90%, in particular 40-80%, of the surface of the outside.
- An embodiment of the bogie frame provides that the upper flange of the connection element has at least one region with reduced thickness. This provides a reduction in the utilization of those welds in the upper area that are closest to the area of reduced thickness.
- the area with reduced thickness is usually made on the same item on the same side as the weld bevel, thereby reloading the wall element between the Manufacturing the area with reduced thickness and the weld chamfers can be omitted.
- the stability is further increased when the upper flange of the connecting element is flush with an upper flange of the longitudinal member, in particular in one piece with it.
- an embodiment of the bogie frame provides that the lower flange of the connection element terminates flush with a lower flange of the longitudinal member, in particular in one piece with it, which likewise leads to an increase in stability.
- the longitudinal axis of the at least one cross member comprises.
- the area may be at the other cross member
- Cross member extends, in particular symmetrically to the longitudinal axis of the cross member.
- outer web of the longitudinal member corresponds to 0.5 to 2.5 times the diameter of the cross member.
- the length of the reduced thickness portion may be outside of 0.5 to 2.5 times in both cases
- Diameter of the cross member lie.
