Definitions

  • the present invention relates to a chassis frame for a chassis of a rail vehicle with a frame body which is adapted to be supported on at least one wheel unit of the chassis. It further relates to a chassis with a chassis frame according to the invention and to a corresponding method for producing a chassis frame.
  • the proportion of cost-intensive manual work can be reduced in principle if cast components are used instead of welded constructions. So it is for example from the GB 1 209 389 A or the US 6,622,776 B2 It is known to use steel castings for a chassis frame of a rail vehicle. While according to the GB 1 209 389 A A one-piece cast bogie frame is manufactured according to the US 6,622,776 B2 the long beams and the cross member of a bogie made of one or more components made of standard cast steel and then assembled into a bogie frame.
  • the cast steel has the advantage that it is weldable, so this conventional joining method is also applicable to this production variant.
  • the steel casting also has the disadvantage that it has a relatively limited flowability. This results in an automated production of relatively large components of complex geometry, such as those chassis frames for rail vehicles, to a reduced process safety, which are unacceptable in view of the high safety requirements that are placed on a chassis of a rail vehicle. Therefore, even in the production of such chassis frame cast iron still relatively many steps to carry out by hand, which is why here - if at all - still can not be achieved in terms of economic aspects satisfactory degree of automation.
  • the present invention is therefore based on the object to provide a chassis frame of the type mentioned, which does not have the disadvantages mentioned above, or at least to a lesser extent and in particular allows easy manufacturability and thus an increased degree of automation of manufacturing.
  • the present invention solves this problem starting from a landing gear frame according to the preamble of claim 1 by the features stated in the characterizing part of claim 1. It solves this problem further starting from a method according to the preamble of claim 29 by the features stated in the characterizing part of claim 29.
  • the present invention is based on the technical teaching that one can achieve a simple manufacturability and thus an increased degree of automation in the production of a chassis frame for a rail vehicle when the frame body is at least partially made of a gray cast iron material.
  • the gray cast iron material has the advantage that it has a particularly good flowability during casting due to its high carbon content and thus leads to a very high process reliability. It has been shown that the production of relatively large complex components for the chassis frame can be done in automated molding boxes, making the production of these components much easier and cheaper.
  • the gray cast iron material is not suitable for welding, since the carbon content in the material is too high. Thanks to the good flowability of the gray cast iron material during casting, however, very complex component geometries can be produced in a reliable manner, which would otherwise have to be produced by elaborate welded constructions. Accordingly, can be dispensed with a variety of joining processes. In addition, for the same reason, an optimized geometry of possibly required joints can be achieved, so that with appropriate design, other joining methods can be used without any problems.
  • gray cast iron material lies in its improved damping properties compared to the steel that is commonly used. This is particularly advantageous in terms of reducing the transmission of vibrations into the passenger compartment of a rail vehicle.
  • the gray cast iron material may be any suitable gray cast iron material. It is preferably a globular gray cast iron material (so-called nodular cast iron), in particular GGG40, which is distinguished by a good compromise between strength, elongation at break and toughness. Preferably z. B. GGG40.3 or GJS-400-18U LT used, which is characterized by an advantageous toughness at low temperatures.
  • the frame body may optionally consist of a single casting. However, because of the size which such frame bodies typically have, it may be advantageous to divide the frame body to achieve high process reliability.
  • the frame body therefore preferably comprises at least two frame parts, which are connected to one another in the region of at least one joint. Preferably, the frame parts, releasably connected together to facilitate later maintenance or repair of the chassis.
  • all frame parts consist of a corresponding gray cast iron material.
  • individual frame parts do not consist of a gray cast iron material.
  • parts of the frame body, for example, one or more cross member of the frame body are formed in a conventional manner as a welded construction and / or as a cast steel castings.
  • frame part is understood to mean a structural part of the frame body which decisively determines the coarse geometry of the frame body. In particular, these should not be connecting elements by means of which such frame parts can be connected.
  • the frame parts can basically be joined together directly by a suitable joining method.
  • at least one connecting element is provided in the region of the joint, which is connected to the two frame parts.
  • the connecting element can be integrally formed with one of the two frame parts. It may, for example, be a projection, such as a pin or the like, which is formed during casting or subsequently and, if appropriate, still provided with the corresponding mating surfaces.
  • connection element with at least one of the two frame parts via a non-positive connection and / or a positive connection and / or a material connection is connected.
  • connection element may be a pin or pin, which is connected to the respective frame part via an interference fit (primarily adhesion in the joining direction) or an adhesive connection (primary material connection in the joining direction).
  • a positive connection can be achieved via corresponding projections and undercuts on the connecting element or frame part.
  • the joint extends at least partially substantially in a joining plane and the connecting element forms at least one projection which extends in the direction of the surface normal of the joint plane at least in a corresponding recess in one of the two frame parts.
  • the connecting element forms at least one projection which extends in the direction of the surface normal of the joint plane at least in a corresponding recess in one of the two frame parts.
  • the connecting element can in principle be designed in any suitable manner. Preferably, it is designed in the manner of a pin or bolt, as has already been stated above.
  • the connecting element can also have any suitable cross-section or cross-sectional profile.
  • it can have a substantially constant cross section over its length, that is to say it can be designed, for example, as a simple cylinder pin or cylindrical pin, since such a shape is particularly easy to produce.
  • the connecting element it is possible for the connecting element to have, at least in sections, a cross-section which tapers with increasing distance from the joining plane. Because of the hereby achievable self-centering of the joining partners thereby simplifies the joining process, so that it can also be done automatically in a simple manner under certain circumstances.
  • the cross-section of the connecting element can also basically be formed in any suitable manner.
  • the connecting element at least in sections a circular cross-section and / or at least partially an elliptical cross-section and / or at least partially a polygonal cross-section.
  • a deviating from the circular shape cross-sectional shape has the advantage of a reliable additional anti-rotation and the automated joining oncoming self-adjustment to the joint axis.
  • fasteners with deviating from the circular cross-section are generally more expensive to manufacture.
  • the connecting element is arranged in the region of a section of the frame body subjected to a static load and / or arranged such that it is subjected to shear stress due to the static load of the frame body.
  • the arrangement in a stretched under static load portion of the frame body has the advantage that the support of torques in the pressure-loaded under static load area can be done easily on the two frame parts to be joined.
  • the connection may possibly even without additional fasteners or only using a simple lift-off in the pressure-loaded under static load area.
  • the primary shear stress ultimately has the advantage that the connecting element, such as a pin or bolt, is loaded in operation mainly in a direction transverse to its joining or mounting direction.
  • the strength of the connection between the two frame parts to be joined is thereby at least largely independent of the quality of the joining process (for example, no special tightening torques or the like are to be considered), but depends only on the properties (eg the shear strength etc.) of the From connecting element. If necessary, therefore, a simple securing of the position of the connecting element (eg via securing rings, press-fitting of the connecting parts, etc.) is sufficient to ensure a permanent and reliable connection of the frame parts.
  • At least one connecting element as the joint bridging, formed with two joining partners element is formed.
  • it may in particular be designed as a tie rod acting in the direction of the surface normal of the joining plane or as a lug bridging the joint.
  • the connecting element has at least one recess for receiving a component of a non-destructive material testing device, in particular an ultrasonic material testing device.
  • This component can be a permanently integrated device that is addressed from time to time.
  • This component can furthermore be a corresponding sensor and / or a corresponding actuator which generates a corresponding excitation of the joining partners.
  • At least one of the cooperating in the region of the joint components is at least partially provided with a friction corrosion preventing coating, in particular a molybdenum (Mo) comprehensive coating, to guarantee a permanently reliable connection.
