Definitions
- the invention relates to a rail vehicle with at least two main cross members running essentially over the entire width of the rail vehicle, to which floor profiles are attached, which extend essentially parallel to the longitudinal direction of the rail vehicle, the main cross members each having a lower flange and at least one upper flange and webs running between them exhibit
- the bending loads in the floor area that occur during the operation of a rail vehicle and are caused by the loading are primarily absorbed or passed on by the main cross members.
- a frequently used embodiment of a rail vehicle has two bogies, one in the long-side end areas of the vehicle, a main cross member being provided above each bogie in order to introduce the wagon load into the respective bogie.Therefore, it is necessary for the main cross members to have a correspondingly high level Have flexural rigidity. To increase the bending stiffness, the profile height of the main cross members can be increased, which should essentially cover the entire height between the upper edges of the bogies and the floor level of the vehicle in order to achieve maximum rigidity. In addition to the main cross members, other cross members are possible to support the floor ,
- the other embodiment is used when the distance between the upper edge of the bogies and the floor level of the rail vehicle is too small to provide main crossbeams with the required profile-high space.
- the floor profiles for the main crossbeams are cut off and with the long sides of the upper straps and side sections welded in the upper area of the webs
- the upper straps of the main cross members replace the upper sides of the floor profiles, which usually form the floor. This measure serves to ensure that the main cross members have a sufficiently high profile even with a small distance between the upper edges of the bogies and the floor level of the rail vehicle
- continuous floor profiles are that they can be used to carry out the production of the floor fully automatically.
- continuous floor profiles result in a significant improvement for welding the floor profiles to the long beams, and since both the floor profiles and the two long beams are over pass through the length of the carriage, they can be welded mechanically. If, on the other hand, the main cross member is inserted into the floor, the longitudinal weld seam on the underside of the floor can only be machined in sections; In the area of the main cross beams, welding has to be carried out by hand, which increases the production costs considerably.
- Another advantage of using continuous floor profiles is that the fully automatic production also results in a very flat floor
- DE 40 05 287 describes a fish-bellied medium-long girder of a goods wagon which has an upper belt which lies in the floor plane
- the US 753 938 A describes a frame for a railroad car, in which mutually parallel long beams are provided, two of which are designed as medium long beams and two as side long beams, which are connected by means of cross beams and cushion elements between a side and one assigned to it
- a long cushion element is arranged in the middle longitudinal member
- Another cushion element is arranged between the two middle longitudinal members, with the tops of the upholstery elements, the cross member and the longitudinal member lying in one plane.
- Bottom plates are between the side longitudinal members and the assigned middle longitudinal members and between the middle longitudinal members provided in the area above a cushion element, in which these base plates adjoin one another, cover plates are arranged
- An object of the invention is to enable the arrangement of continuous floor profiles even with a very small distance between the upper edge of the bogie and the floor level of the rail vehicle, the main cross members should have the required bending stiffness
- a section of the floor profiles lies in the area of the corresponding main cross member, which increases the profile height and achieves the required bending stiffness without the floor profiles cut off at the main cross member
- a favorable embodiment is that the webs are welded to the underside of the floor profiles.
- An advantageous embodiment for connecting one or more top chords to the floor profiles is that the at least one top chord is welded to the top of the floor profiles.
- an advantageous embodiment consists in that a main cross member has two top chords which are welded to the top of the floor profiles at a predetermined distance from one another. This measure compares the ratio of the belt area to the weld seam area a continuous top chord with the same area is lowered and the adhesion with the floor profiles is considerably improved Since, in a preferred embodiment, an air spring, the diameter of which essentially corresponds to the width of the main cross member, is provided under the lower chord of the main cross member, the air pressure in the spring causing the lower chord to bend, in a favorable embodiment, the plate stiffness is concerned of the lower chord to be increased locally, a web is provided under the area lying between the upper chords
- a low weight of the main cross member is achieved in that the material of the main cross member is aluminum
- a low weight of the floor can be achieved by the material of the floor profiles being aluminum
- main cross member which is light in weight, is that the main cross member is made of cast aluminum
- FIG. 1 shows a cross section through the upper part of a rail vehicle
- FIG. 2 schematically shows a section of the floor of the rail vehicle from FIG. 1 in the area of a main cross member in a perspective view, partly in section, and
- FIG. 3 shows a section along the line III-III in FIG.
- floor profiles 3, the upper sides 3b of which can form the floor, are fastened to a main cross member 2 of a rail vehicle, as can also be seen from FIGS. 2 and 3.
- Exactly two upper straps 5a, 5b of the main cross member 2 are arranged above the floor profiles 3, as can be seen from FIGS. 2 and 3, with the top 3b of the Floor profiles 3 are welded
- the welding of the upper straps 5 a, 5b can be carried out relatively easily since they are simply placed on the continuous floor profiles 3 and then the side surfaces of the upper straps 5a, 5b are welded to the upper side 3b. Since the welded connections 13 have an essentially straight course, this process can also be carried out by machines.
- the time-consuming and cost-intensive, manual welding of the floor profiles 3 with the long beams 8 is omitted
- the floor profiles 3 have diagonal compartments 9. Below the floor profiles 3, webs 6a, b, c are made from a lower flange 4 of the main cross member 2 to the underside 3a of the floor profiles 3 and with the underside 3a Floor profiles 3 welded The welding of the underside 3a to the webs 6 can also be done mechanically because of the widening 7 of the web ends
- a bogie (not shown here) is provided under the main cross member 2, the carriage load being introduced into the bogie via the main cross member 2
- the main cross members 2 are connected to long supports 8, which extend essentially over the entire length of the rail vehicle, to form a supporting structure, the long supports 8 being connected to the lower ends of side walls 10 of the rail vehicle, which are essentially normal run to the upper chords of the long girders 8.
- the upper ends of the side walls 10 have a connection with one another, in the form of a roof 11.
- the embodiment shown here has two upper chords 5a, b for each main cross member 2. As already described above, this embodiment creates a particularly good connection between the upper chords 5a, b and the floor profiles 3, since this results in the ratio of the area of the upper chords 5a, b to the area of the weld seam 13, as shown in FIG. 3 , significantly improved compared to a variant with only a very wide top flange 5.
- an air spring (not shown in the drawing) is provided under the lower flange 4, which exerts pressure, which results in a bending load on the lower flange 4, the plate stiffness in the area between the two upper belts 5a, 5b is increased locally of the main cross member 2, a further web 6b is provided.
- This is connected to the lower flange 4, but is not welded to the underside 2a of the floor profiles 2, since it exclusively performs a supporting function and only absorbs compressive forces
- diagonal infills 9 transmit the loads that occur between the upper chord 5 and lower chord 4, in particular shear stresses due to transverse forces that occur.
- the diagonal infills 9 assume the function of the webs 6 of the main cross member 2
- the invention allows the installation of continuous floor profiles 3 even with a very small free space between the upper edge of the bogie and the floor level of the rail vehicle, since the position of the floor profiles 3 in the area between the lower flange 4 and the upper flange 5a, 5b of the Main cross member 2 its profile is increased to the height h and thereby the required bending stiffness is achieved without requiring additional space below the floor profiles
- the webs 6a, 6c are each connected to the underside 3a of the floor profiles 3 by an external weld seam 14, the webs 6a, 6b, 6c and the lower flange 4 being simple and inexpensive to manufacture from one piece
- main cross member 2 in addition to the main cross member 2, other cross members, not shown in the exemplary embodiment shown, are provided for further supporting the floor, which, however, do not have to take up such great loads and can therefore have a lower profile height than the main cross member 2, as a result of which they are all under the floor profiles 3 Find space
- the main cross member 2 in the present invention is made of cast aluminum for cost reasons
