Description

Uppfinnare: G Schtitze, K Rosenbaum och H Hertel Prioritet begard fran den 11 mars 1955 (Forbundsrepubliken Tyskland) Foreliggande uppfinning hanfor sig till vaxeltungor for enskenehogbanor, vid vilka fordonen sadelformigt omgripa barkropp. Vid banor av detta slag 18pa fordonens bdrhjul pa Oversidan av barkroppen, och sidohjulen styras mot sidorna av den balkformiga barkroppen. Inventors: G Schtitze, K Rosenbaum and H Hertel Priority requested from 11 March 1955 (Federal Republic of Germany) The present invention relates to gear tongues for English high-speed railways, in which the vehicles saddle-grip the bar body. On tracks of this kind 18p the vehicle's wheel on the upper side of the support body, and the side wheels are guided towards the sides of the beam-shaped support body.

Vid dylika banor liar redan foreslagits att sasom vaxeltunga anvanda en eller flera med banan svangbart forbundna, raka och stela avsnitt av barkroppen. Vid tungfastena bildas emellertid knackstallen, vilka da fordonen kora snabbt genom vaxeln medfora avsevarda st5tar, varfor dylika sparvaxlar endast kunna anvandas i relativt liten utstrackning. In such tracks, it has already been proposed to use, as a gear tongue, one or more sections of the bar body pivotally connected to the track. At the tongue fasteners, however, the knock stables are formed, which when the vehicles run quickly through the gear unit carry considerable strides, for which reason such spare shafts can only be used to a relatively small extent.

Andamalet med uppfinningen dr att astadkomma sadana vaxeltungor, vilkas barkropp bestar av en eller flera i och for sig stela avsnitt av barkroppen och aro sa utformade, att fordonen kunna koras snabbt och stotfritt genom vaxeln, Liven dA denna Ar installd for banans bispar. The object of the invention is to provide such gear tongues, the support body of which consists of one or more in itself rigid sections of the support body and are so designed that the vehicles can be driven quickly and without impact through the gear.

Detta andamal uppnas enligt uppfinningen darigenom, att vid en sparvaxel for enskenehogbanor med balkformig barkropp, vars oversida bildar en lopbana f8r fordonets barhjul och vars sidoytor var och en bilda atminstone en lopbana for fordonets sidostyrhjul, atminstone en av styrhjulslopbanorna är utford sasom ett element, vilket dr oberoende av vaxeltungans barkropp installbart i en rak riktning eller en svangd riktning med jamn kraning. This object is achieved according to the invention in that in a spare shaft for single-track high beams with beam-shaped bar body, the upper side of which forms a raceway for the vehicle's bar wheels and whose side surfaces each form at least one raceway for the vehicle side wheels, at least one of the steering wheel races is challenged. independent of the barrel tongue of the wax tongue installable in a straight direction or a curved direction with even crane.

Enligt uppfinningen besta de av vaxeltungans barkropp oberoende installbara styrhjulslopbanorna foretradesvis av fjadrande install-barn metallband, vilka medelst mekaniskt, elektriskt, hydrauliskt eller pneumatiskt manovrerbara omstallningsanordningar dro installbara for bildande av en rak bana, dâ vaxeltungan befinner sig i sitt raka lage, resp. en krokt kurvbana med den onskade konstanta krokningen, da vaxeltungan befinner sig I sitt utsvangda lage. According to the invention, the installable guidewire raceways independent of the shaft body of the gear tongue are preferably composed of resilient installer-child metal belts, which by means of mechanically, electrically, hydraulically or pneumatically manoeuvrable adjusting devices become installable for forming a straight path. a crooked curve path with the desired constant croaking, when the wax tongue is in its forced layer.

Den fjadrande omstallningen av styrhjulslopbanorna fordrar en icke ovasentlig kraft. Denna kan enligt en utforingsform av uppfinningen minskas genom att man i stallet for bojliga styrhjulslopbanor anvander 1 och for sig stela »utfyllnadselement», vilka Aro anordnade att lyftas eller sankas for att bringas i resp. arbetslage. The resilient conversion of the steering wheel raceways requires a not insignificant force. According to an embodiment of the invention, this can be reduced by using 1 and separately rigid «filling elements» instead of flexible guide wheel tracks, which Aro are arranged to be lifted or collected in order to be brought into resp. working class.

Figs. 11-16 show a truss body for the Axeltungan challenged in truss construction with two spare tracks for the bar wheels, which are challenged with double spare rings, and with the guide wheel race tracks arranged to be installed by means of filling elements, the tongue body being shown in a side view, a top view .

Vid utforingsformen enligt fig. 1 och 2 be-star den svangbara vaxeltungan av tva barkroppsavsnitt 1, vilka forbinda anslutningsstrackorna 2. Vaxeltungans barkroppsavsnitt 1 vila pa stodfotter 3, vilka Aro rorliga pa styrbanor 5 fastade vid barplattor 4. Omstallning av vaxeltungan utfOres medelst en vid vaxeltungan fast kuggstang 6, win samverkar med ett kugghjul 7. I dndlagena anligga barkroppsavsnitten 1 mot anslag 8, medelst vilka vaxelns kurvform är fastlagd. Forregleringar 9 hAlla stodfotterna 3 i vaxeltungans 2— — andlagen. Barkroppsavsnitten 1 aro svanghart forbundna med varandra och med en av strackorna 2 medelst leder 10. In the embodiment according to Figs. 1 and 2, the pivotable gear tongue consists of two bar body sections 1, which connect the connecting tracks 2. The bar body section 1 of the shaft tongue rests on stand feet 3, which are movable on guide tracks 5 attached to bare plates 4. Adjustment of the gear tongue means the gear tongue fixed rack 6, the winch cooperates with a gear 7. In the lower layers the bare body sections 1 abut against abutment 8, by means of which the curve shape of the gear is fixed. Pre-adjustments 9 All footrests 3 in the gear tongue 2— - andlagen. The corpora cavernosa sections 1 are pivotally connected to each other and to one of the stretches 2 by means of joints 10.

Fig. 1 visar en vy ovanifran av en vaxel enligt uppfinningen i ett rakt utgangslage, och fig. 2 visar samma vaxel i ett kurvlage. For att sparbanan for fordonets barhjul aven i kurvlaget skall ha tillracklig bredd pa alla stallen, aro de sidor av barkroppsavsnitten, vilka i kurvlaget befinna sig p5. kurvans utsida (i fig. 1 och 2 den byre sidan) bagformigt utbuktade, medan insidorna av barkroppsavsnitten 1 aro raka. Fig. 1 shows a top view of a gear according to the invention in a straight starting position, and Fig. 2 shows the same gear in a curved position. In order for the saving path for the vehicle's bar wheels also in the cornering layer to have a sufficient width in all stables, the sides of the bare body sections which are in the cornering layer are p5. the outside of the curve (in Figs. 1 and 2 the straight side) is rear-shaped curved, while the insides of the bare body sections 1 are straight.

Vid flerdelade vaxeltungor och framfor alit i de fall, da barkroppsavsnitten hos vaxeltungan endast aro svangbara relativt varandra i mindre utstraekning, Or utbuktningen av den ena sidan av barkroppsavsnitten onodig. In the case of multi-part gear tongues and above all in cases where the bare body sections of the gear tongue are only pivotable relative to each other to a lesser extent, the bulging of one side of the bare body sections is unnecessary.

Fig. 3 och 4 visa strackningen av de under k5rbanan liggande styrhjulslopbanorna 11 i ett rakt lOge resp. i ett kurvlage. Vid omstallning av vaxeltungan installas styrhjulslopbanorna 11 antingen genom elastisk deformation medelst omstallningsanordningar eller genom anvandande av utfyllnadselement. I fig. 3 visas styrhjulslopbanorna i ett rakt lage och i fig. 4 Oro de installda for en kurvf or-mad bana. Figs. 3 and 4 show the stretching of the guide wheel raceways 11 under the carriageway in a straight position and in a curve layer. When adjusting the gear tongue, the guide wheel raceways 11 are installed either by elastic deformation by means of adjusting devices or by using filling elements. Fig. 3 shows the guide wheel raceways in a straight line and in Fig. 4 they are set up for a curved path.

I fig. 5 visas genom tvarforskjutning installbara, elastiskt eller fjadrande deformerbara styrhjulsbanor 11, varvid barkroppsavsnittet 1 utg8res av en ungefarligen rektangular fackverksbalk. Lopbanan for barhjulen bestar av Ire parallella U-formiga profiler 12 med phsvetsade platar 13. Plattans 13 sidor aro fOrstarkta medelst vinkelprofiler 14, vilkas yttre skanklar Oro riktade neat. Fig. 5 shows instillable, resilient or resiliently deformable guide wheel tracks 11 by transverse displacement, the bare body section 1 being formed by an approximately rectangular truss beam. The raceway for the bar wheels consists of Ire parallel U-shaped profiles 12 with welded plates 13. The sides 13 of the plate are reinforced by means of angle profiles 14, the outer shanks of which are not oriented.

Aven styrhjulslopbanorna 11 besta av en U-profil 15 med en pasvetsad plat 16 och Oro infallda i hogkantstallda, i sidled forskjutbara plattor 17, vilka Oro lagrade mellan tva vertikala, 'Ara varandra liggande fackverksstanger och vim a pa vinkeljarn 18. Vinkeljarnen 18 bilda samtidigt Over- resp. understanger i fackverksbalken. Plattorna 17 ha i den del, som befinner sig inuti fackverksbalken, en relativt stor, cirkelformad urborrning, genom vilken en axel 19 stracker sig och Or forsedd med en havarm eller excenter 20. Allt- efter havarmens 20 'age befinna sig styrhjulslOpbanorna 11 i sitt raka eller 'Ada. lage. De vertikala balkstangerna Oro nedtill forlangda och forbundna med stOdfoten 3, vars rullar 21 vila pa den sasom skena utforda styrba- nan 5. Alit efter den erforderliga utbojningen av styrhjulslopbanorna 11 andrar sig havarmens 20 langd, sit att styrhjulslopbanorna erhalla den onskade konstant krokta kurvformen. The guidewheel raceways 11 also consist of a U-profile 15 with a fitted welded plate 16 and Oro recessed in right-angled, laterally displaceable plates 17, which Oro are mounted between two vertical, adjacent truss rods and which are on angle iron 18. The angle iron 18 forms simultaneously Over- resp. supports in the truss beam. The plates 17 have, in the part which is located inside the truss beam, a relatively large, circular bore, through which a shaft 19 extends and Or is provided with a sea arm or eccentric 20. Depending on the age of the sea arm 20, the guide wheel tracks 11 are in their straight or 'Ada. lage. The vertical beam rods Oro at the bottom are required and connected to the support foot 3, whose rollers 21 rest on the rail challenging the guide track 5. After the required extension of the guide wheel raceways 11, the length of the sea arm 20 changes, so that the guide wheel raceways receive the desired constant shape.

Vid den i fig. 6 cell 7 visade utforingsformen astadkommes den fjadrande eller elas- tiska deformationen av styrhjulslopbanorna 11 medelst excenterskivor 22, vilka var och en aro fastade ph en i vaxeltungans langd- riktning sig strackande vridaxel 23. Pa styrhjuls18pbanorna 11 Oro pa ena sidan fastade platar 24, vilka aro forsedda med. borrningar 25, i vilka excenterskivorna Oro anordnade att kretsa. De pa barkroppens andra sida liggande styrhjulslopbanorna 11 aro ledbart forbundna med platarna 24 medelst stanger 26, sit att de pa omse sidor om barkroppen belagna styrhjulslopbanorna omstallas samtidigt. In the embodiment shown in cell 7 in Fig. 6, the resilient or elastic deformation of the guide wheel raceways 11 is effected by means of eccentric discs 22, each of which is fixed to a pivot axis 23 extending in the longitudinal direction of the gear tongue. fixed plates 24, which are provided with. bores 25, in which the eccentric disks Oro arranged to circuit. The guide wheel raceways 11 lying on the other side of the support body are hingedly connected to the plates 24 by means of rods 26, so that the guide wheel race tracks coated on opposite sides of the support body are rearranged at the same time.

I fig. 8 visas en med tryckmedium arbetande omstallningsanordning. I betongkroppens urtagninuar 27 Oro anordnade ett erforderligt antal tryckcylindrar 28, vilkas kolvar 29 astadkomma omstallningen av styrhjulslopbanorna 11 medelst det pa kolvundersidan verkande trycket mot verkan av en fj Oder 30. DA tryckmediet avgar trycker fjadern 30 kolven 29 till vilolaget och samtidigt foras styrhjulslopbanorna Oven till sitt vilolage. Havarmsforbindelsen 31, 32 Or anordnad att i sitt strackta lage ga nagot Over det vagrata laget for delarna 32 och bildar darigenom ett fast andlage utan att kolven 29 paverkas i detta lage for delarna 32. Fig. 8 shows a switching device operating with a pressure medium. In the recess 27 of the concrete body arranged a required number of pressure cylinders 28, the pistons 29 of which effect the adjustment of the guide wheel raceways 11 by means of the pressure acting on the piston underside against the action of a spring 30. When the pressure medium emits its resting position. The sea-arm connection 31, 32 is arranged to, in its stretched layer, go slightly over the horizontal layer for the parts 32 and thereby form a fixed abutment without the piston 29 being affected in this layer for the parts 32.

Den fjadrande utbojningen av styrhjulslopbanorna 11 erfordrar en icke ovasentlig kraft. Denna kan emellertid minskas om man i still-let for de bOjliga styrhjulsbanorna anvander I och for sig stela »utfyllnadselement›, vilka bringas i sina resp. arbetslagen genom lyftning eller sankning. The resilient deflection of the guide wheel raceways 11 requires a not insignificant force. However, this can be reduced if, instead of the flexible guide wheel tracks, rigid "filling elements" are used per se, which are brought into their respective positions. the work team by lifting or lowering.

En dylik utforingsform visas i fig. 9. De segmentformiga utfyllnadsstyckena 33 Oro fastade pa barare 34, vilka aro vertikalt forskjutbart anordnade, t. ex. medelst kuggstanger 35, vilka kunna omstallas i motsatta riktningar medelst ett ph en axel 36 anordnat kugghjul 37. Such an embodiment is shown in Fig. 9. The segment-shaped filler pieces 33 are fastened to carriers 34, which are arranged vertically displaceably, e.g. by means of gears 35, which can be adjusted in opposite directions by means of a gear 37 arranged on a shaft 36.

Fig. 10 visar en annan utforingsform, dar de ovre styrhjulslopbanorna 11 Oro anordnade att fOrskjutas pit tvaren medelst omstallningsanordningar och darvid bojas elastiskt, n-iedan endast de undre styrhjulslopbanorna installas genom svangning av utfyllnadsstycken 33, vilka Oro svangbart lagrade pa axlar 38. Fig. 10 shows another embodiment, in which the upper guide wheel raceways 11 are arranged to be displaced by means of adjusting devices and thereby bend elastically, n-before only the lower guide wheel raceways are installed by pivoting filler pieces 33, which are pivotally mounted on axles 38.

Uppdelningen av tungans barkropp i endast tva barkroppsavsnitt 11 medfor den out- genheten, att barhjulsbanan pa barkroppen maste utf8ras pa sadant satt, att den liar den erforderliga bredden for barhjulen saval vid vaxelns raka som svangda lage. Harigenom minskas fordonsprofilen i hojd med korba- nan. Denna olagenhet kan enligt uppfinningen minskas samtidigt som vaxeltungans uppdelning i ett flertal barkroppsavsnitt mojliggores, om barhjul med dubbelsparkrans anvandas. The division of the tongue's bar body into only two bar body sections 11 entails the fact that the bare wheel path on the bar body must be designed in such a way that it has the required width for the bar wheels both at the straight and curved bearings of the gear. This reduces the vehicle profile at the height of the track. According to the invention, this inconvenience can be reduced at the same time as the division of the gear tongue into a plurality of bare body sections is made possible, if bar wheels with a double spar ring are used.

Dylika utforingsformer visas i fig. 11-16. Denna konstruktion Or uppbyggd som en fack- verksbalk i jarnkonstruktion. I fig. 11 visas vaxeltungan i en sidovy.
