Definitions

• the present invention relates to a track for a track-bound vehicle, in particular a magnetic levitation train, with a bracket for connecting a carrier to at least one attachment (functional part) attached to the bracket by means of the bracket for guiding the vehicle, and a method for producing a bracket.
• Elevated railways usually have girders spaced from one another, between which plates which accommodate the guideway are arranged and extend from girder to girder.
• the beams absorb both the static and the dynamic forces and must therefore first be dimensioned according to the size of the loads to be absorbed. Since the carriers in many cases, especially in the case of magnetic high-speed trains, also take up functional parts of the same which, due to their function, permit only slight positional deviations, it is very difficult to comply with these relatively narrow tolerances to produce the carriers together with the supporting elements for the functional parts in one go.
• BESWIGUNGSKDP1E EP 0 410 153 A1 discloses a support structure for the route of a track-bound vehicle.
• the required beams are either made of steel or concrete.
• Equipment is attached to the carrier in the correct position.
• connecting bodies are arranged on the carrier, which have first stop surfaces. These first stop surfaces correspond to second stop surfaces which are arranged on cross members connected to the equipment part. After the lugs have been fastened to the carrier with the first stop surfaces, these first stop surfaces are machined so that the required tolerances for the attachment of the equipment parts are maintained when interacting with the second stop surface of the fastening means of the equipment parts.
• the machining of the stop surfaces should preferably be carried out in an air-conditioned factory hall under controlled conditions.
• a disadvantage of this procedure is that the processing of the stop surfaces may be done correctly in relation to the carrier.
• the production of the precise tolerance fasteners appears to be very complex.
• a travel path according to the invention has a console with at least one, preferably two webs, which are connected to the carrier at their first end and an essentially vertical one at their second end have arranged for extending the webs receptacle for attaching the add-on.
• a console according to the invention is thus created, which is particularly advantageously suitable for machining the connection point between the console and the attachment or between the carrier and the attachment. While in known arrangements the supports for the guideway are formed in one piece with the support elements for the functional parts and therefore changes in position of the supports have a direct effect on the position of the support elements for the functional parts and are therefore no longer correctable, the invention is based on the idea of a separation of the supports for the route from the support elements for the functional parts.
• console and / or the add-on part can be produced in a very simple and cost-effective manner.
• the previously very complex manufacture of the console as a cast part is eliminated.
• the present invention has the advantage that there is no longer any need to fear dangers due to destruction of the console due to blowholes contained in the cast part. The cost-intensive inspections of the components are therefore also eliminated.
• rolled profiles can be designed to be substantially more elastic than cast parts in areas that are not critical for driving operation and thus can compensate for thermal expansion occurring in the add-on parts far better.
• the webs are connected to one another at their first and / or their second end.
• the connection creates a special stability with regard to mechanical stress on the webs, for example when connecting to the attachment.
• connection point between the attachment and the console or carrier consists of a receptacle, which forms a contact surface for the attachment.
• This Recording is in particular a head plate, which is attached to the web or webs.
• a separate head plate is arranged on each web.
• the advantage is, in particular, that in the event of bumps in the attachments, which are limited in their lengths, a better compensation for the alignment can take place.
• the separate contact surface of the different head plates can also be processed differently.
• a longitudinal expansion which is caused by temperature influences on the attachments, can be compensated better if a head plate is arranged on each web.
• the head plate has protrusions as a contact surface, it is particularly easy to process the head plate.
• the contact surface is specially designed for mechanical processing.
• the top plate is arranged essentially at right angles to the web. This enables a particularly good introduction of force. In addition, editing is easy. This also facilitates the mounting of the attachments on the head plate or the console, since accessibility is improved.
• L-shaped, T-shaped, Z-shaped or U-shaped designs have emerged as particularly advantageous forms for connecting the head plate to the webs. This allows a particularly good arrangement of the attachments on the head plate with simultaneous good stability or compensation of changes in temperature and length.
• the web and / or the top plate has bores or threads for receiving fastening screws and / or transverse force bolts. With the help of these screws and shear bolts allows the attachment parts to be reliably attached to the console.
• the material of the webs and / or the head plates is metal that can be machined and / or welded, in particular steel.
• the solution according to the invention in which the distance between two brackets in the longitudinal direction of the travel path is essentially an integer part of the length of the add-on unit, offers, due to its modular structure, the further advantage that the brackets and also the supporting elements can be mechanically processed either before and after their attachment and can be easily replaced later for maintenance purposes. Even high tolerance requirements can be met relatively easily in all spatial axes.
• the modular structure also enables simple replacement of supporting elements for the functional parts that have been damaged by accidents, for example.
• the space curve required for the functional level can be realized inexpensively by appropriate design and / or processing of the console items. Gradients are approximated polygonally. It is particularly advantageous if the module length is an integer multiple of a basic grid, for example a stator packet length. With a stator packet length of approximately 1 m, a module length of approximately 3 m has proven to be advantageous.
• the various functional areas of the add-on unit are summarized in the module.
• brackets In order to be able to compensate for particularly large changes in position, different brackets can be provided which have webs of different lengths. As a result, an enlarged bracket can be used in the event of a very large displacement of the carrier from its target position, which finally attaches the attachment in the desired position. Um .
• the webs are connected to one another at their first and / or their second end. The connection creates a special stability with regard to mechanical stress on the webs, for example when connecting to the attachment.
• connection point between the attachment and the console or carrier consists of a receptacle, which forms a contact surface for the attachment.
• This receptacle is in particular a head plate, which is attached to the one or more webs.
• a separate head plate is arranged on each web.
• the advantage is, in particular, that in the event of bumps in the attachments, which are limited in their lengths, a better compensation for the alignment can take place.
• the separate contact surface of the different head plates can also be processed differently.
• a longitudinal expansion which is caused by temperature influences on the attachments, can be compensated better if a head plate is arranged on each web.
• an alternative embodiment provides that the console is screwed to the carrier, in particular to a tie rod arranged in the carrier.
• the tie rod can be concreted in the girder or located in an empty pipe and thus combine two brackets on both sides of the girder with at least one tie rod to form a structural unit.
• a particularly simple design is obtained here, which is very easy to handle both during assembly and when disassembly is required.
• a threaded Rod that extends across the beam from one console to the opposite console.
• the footplate can either be arranged outside the carrier and be supported on the carrier. In another embodiment, however, it can also be concreted into the carrier and thus create an additional connection between the console and the carrier.
• the console can be attached and replaced in a simple manner.
• the centering holes ensure that the console is positioned exactly.
• a bracket is advantageously arranged at the joint between two add-on parts.
• This one console thus reliably connects the two attachments to the carrier.
• the web design of the console makes it easy to compensate for a longitudinal expansion of the add-on parts, which cannot be avoided by temperature influences, without causing tension in the mounting of the add-on part. It is particularly advantageous if the first add-on part is connected to the first web or the first head plate and the second add-on part is connected to the second web or the second head plate. The two webs or head plates can then compensate for the thermal expansion by means of a movement relative to one another.
• a component which is essentially box-shaped in cross section and has an integrated mounting surface, lateral guide surface and stator attachment has proven to be a design for the attachment part. This makes it easy to install- guaranteed when attaching the functional parts to the console or the carrier.
• a number of brackets are manufactured by forming a rolled section strand with essentially at least a partial cross section of the bracket by extrusion rolling. and then the rolled profile strand is disassembled at intervals of the desired bracket width.
• the disassembly is typically carried out by sawing the rolled profile strand, but methods such as cutting firing or laser cutting can also be used.
• the console pieces thus produced can still be reworked, e.g. the cut edges are deburred and the cut surfaces are smoothed.
• the brackets are produced in the process according to the invention without inclusions, such as cavities, and a reproducible, consistently high quality of the brackets can be guaranteed.
• their quality can be increased even further. Since a large number of brackets are cut from the meter-long rolled profile strands, the manufacturing costs are reduced compared to the individual manufacture of brackets by casting.
• a composite rolled profile strand can be produced with a cross section that would not be producible with the conventional rolling processes or only with disproportionately high expenditure.
• the meter-long profile strands can be welded to one another by means of a continuous weld seam, which guarantees a constant quality over the length of the profile strand and promotes automation of the welding process.
• the separation of the rolled section into the individual Consoles advantageously take place after the individual partial cross sections have been joined to form the overall cross section.
• the assembled profile strand is formed from two symmetrically composed rolled profile strands.
• the two rolled profile strands can therefore be produced with the same rolling tool, which reduces the development effort and the manufacturing expenditure for the rolled profiles.
• the welding compound can be distributed over both surfaces to be joined when the two surfaces are welded. This increases the load capacity of the welded connection between the two rolled sections.

• the head plate 3 was made with an oversize on the side of the add-on part to be assembled later (FIG. 1). This is milled after mounting the bracket 1 on the end face of the carrier 2 in order to compensate for manufacturing tolerances of the carrier 2 in the transverse direction of the carriageway in order to ensure the dimensional accuracy of the path width when the attachment 4 is subsequently attached to the head plate 3.
