40 461 969 Sageraffla . 40 461 969 Sageraf fl a.
Tillsammans med detta medger en anordning enligt uppfin- ningen en optimal ákkvalité som uppnås med hjälp av lämpliga successiva och lätt optimerbara modifikationer. Dessa kan med fördel göras pà prototypboggier, varvid det ej är nödvändigt ëâ att stanna standard-massproduktionen, mätande accelerationerna i horisontalplanet under testfärder pà platsen och därmed i a-cåx funktion av spàrets verkliga karaktäristika.Together with this, a device according to the invention allows an optimal ride quality which is achieved with the aid of suitable successive and easily optimizable modifications. These can advantageously be made on prototype bogies, whereby it is not necessary to stop the standard mass production, measuring the accelerations in the horizontal plane during test trips on site and thus in a-cåx function of the track's actual characteristics.
Uppfinningen kommer att beskrivas nedan närmare i detalj utgående fràn en föredragen praktisk utföringsform, som visas pà ritningen endast som exempel angivande den del av en järn- vägsboggi som innehåller den primära fjädringen, i anslutning till vilken anordningen är installerad utgörande ändamålet för uppfinningen. Närmare bestämt visar fig¿_¿ en sidovy av nämnda del och §igå_2 ett snitt längs linjen II-II i fig. 1.The invention will be described below in more detail starting from a preferred practical embodiment, which is shown in the drawing only as an example indicating the part of a railway bogie which contains the primary suspension, in connection with which the device is installed constituting the object of the invention. More specifically, Fig. 2 shows a side view of said part and Fig. 2 a section along the line II-II in Fig. 1.
Den visade delen av boggien är huvudsakligen bildad av , fjädern 2, av hjulaxellagerhuset 3 (en lagerhylsa), av lagren 4, av hjulet 5 och av ramens 6 sidodel.The part of the bogie shown is mainly formed by, the spring 2, by the wheel axle bearing housing 3 (a bearing sleeve), by the bearings 4, by the wheel 5 and by the side part of the frame 6.
Fjädern 2, visad pa ritningen, är av känd typ av gummi.The spring 2, shown in the drawing, is of known type of rubber.
Den uppfyller alla erfordrade funktioner: funktionen att elastiskt uppbära den vertikala belastningen och att elastiskt överföra alla krafter verkande i horisontalplanet mellan lagerhuset 3 (lagerhylsan) och boggiens 6 ram.It fulfills all the required functions: the function of resiliently supporting the vertical load and of resiliently transmitting all forces acting in the horizontal plane between the bearing housing 3 (the bearing sleeve) and the frame of the bogie 6.
Fjädern 2 av gummi kan ha stympat konisk form upptagen och vridbar i metallhuselementen 7 och 8, eller av den stympat koniska ringformade typen, härdad pà nämnda metalldelar.The spring 2 of rubber may have a frustoconical shape received and rotatable in the metal housing elements 7 and 8, or of the frustoconical annular type, hardened on said metal parts.
Fjädern 2 kan även vara av någon annan känd typ, ej visad på ritningen, vid vilken funktionen att elastiskt upp- bära den vertikala lasten och funktionen att elastiskt överföra krafterna i horisontalplanet är skilda ät. I detta fall är den vertikala belastningen elastiskt uppburen med hjälp av en gummifjäder i form av en enda skiva eller av flerskivtyp, eller med hjälp av en skruvfjäder av stàl, medan . krafterna verkande i horisontalplanet överförs med hjälp av en gummiring fritt vridbar i ett metallsäte med cylindrisk yta. « Vid alla dessa typiska tillämpningar framgår det att frihetsgraden för den primära fjädringen i horisontalplanet regleras av den elastiska karaktäristikan i detta plan hos gummiringen. 40 3 461 969 Denna karaktäristika kan, efter det att konstruktionen har avslutats, ej längre varieras på lämpligt sätt eller kan den anpassas och optimeras till de kända boggierna som en funktion av spårtyp och typ av fordon.The spring 2 can also be of another known type, not shown in the drawing, in which the function of elastically supporting the vertical load and the function of elastically transmitting the forces in the horizontal plane are different. In this case, the vertical load is resiliently supported by means of a rubber spring in the form of a single disc or of a multi-disc type, or by means of a helical spring of steel, while. the forces acting in the horizontal plane are transmitted by means of a rubber ring freely rotatable in a metal seat with a cylindrical surface. «In all these typical applications it appears that the degree of freedom of the primary suspension in the horizontal plane is regulated by the elastic characteristics of this plane of the rubber ring. 40 3 461 969 This characteristic can, after the construction has been completed, no longer be suitably varied or it can be adapted and optimized to the known bogies as a function of track type and type of vehicle.
För att övervinna denna nackdel är anordningen enligt uppfinningen framtagen, vilken på ritningen anges med 1.To overcome this disadvantage, the device according to the invention has been developed, which is indicated in the drawing by 1.
Nämnda anordning är bildad av en styrkropp 1 gjord av ett antislitagematerial med lämplig elasticitet och anordnad på löstagbart sätt mellan huset 3 och metallelementet 8 (inne- hållande fjädern 2), vilket är fast anordnat tillsammans med sidodelen 6 hos boggiens ram. Styrkroppen 1 har vertikala antislitageytor i längsgående och tvärgående plan i kontakt- arean mellan huset 3 och elementet 8. Den verkar sålunda som ett tvärgàende och längsgående styrelement mellan huset 3 (och därmed hjulet 5) och elementet 8 (och därmed sidodelen 6 hos boggiens ram).Said device is formed by a guide body 1 made of an anti-wear material with suitable elasticity and arranged in a detachable manner between the housing 3 and the metal element 8 (containing the spring 2), which is fixedly arranged together with the side part 6 of the bogie frame. The guide body 1 has vertical anti-wear surfaces in longitudinal and transverse planes in the contact area between the housing 3 and the element 8. It thus acts as a transverse and longitudinal guide element between the housing 3 (and thus the wheel 5) and the element 8 (and thus the side part 6 of the bogie frame). ).
Företrädesvis är två kroppar 1 anordnade förlagda sym- metriskt pà motsatta sidor om hjulets 5 axel.Preferably, two bodies 1 are arranged arranged symmetrically on opposite sides of the axis 5 of the wheel 5.
Genom att på lämpligt sätt variera tjockleken hos krop- pen eller kropparna 1, kan spelrummets värde mellan huset 3 och sidodelen 6 hos boggien varieras i längdriktningen såväl som i tvärriktningen, lika eller olika och med stöd av de ovan nämnda accelerationsmätningarna.By suitably varying the thickness of the body or bodies 1, the value of the clearance between the housing 3 and the side part 6 of the bogie can be varied in the longitudinal direction as well as in the transverse direction, equal or different and with the support of the above-mentioned acceleration measurements.
Variationen av spelrummet ger en variation pà svaret beträffande frekvens liksom amplitud hos den primära fjädring- en i horisontalplanet. Det är därför möjligt att bestämma, under försök på platsen, det optimala värdet för detta spelrum för vilket, vid det komplexa multimassdynamiska fenomenet betraktas, som funktion av oregelbundenheter hos spåret och hos fordonets hastighet, minimumvärdena alstras av accelera- tionerna och är det därmed möjligt att installera anordningen 1 för den lämpligaste åtgärden för att uppnå ett optimalt uppträdande och en optimal åkkomfort hos fordonet längs hela sträckningen.The variation of the clearance gives a variation of the response in terms of frequency as well as amplitude of the primary suspension in the horizontal plane. It is therefore possible to determine, during on-site tests, the optimum value for this clearance for which, in the complex multimass dynamic phenomenon considered as a function of irregularities of the track and of the vehicle speed, the minimum values are generated by the accelerations and it is thus possible to install the device 1 for the most suitable measure in order to achieve an optimal behavior and an optimal riding comfort of the vehicle along the entire route.
Kroppen 1, som företrädesvis har sitt tvärsnitt U-format kan vara fastsatt på huset 3, som visas på ritningen, eller vid elementet 8 i ett stycke med boggiens ram.The body 1, which preferably has its U-shaped cross-section, can be attached to the housing 3, as shown in the drawing, or to the element 8 in one piece with the frame of the bogie.
Som underförstås av vad som ovan beskrivits kan anord- ningen enligt uppfinningen enkelt installeras i varje typ av primär fjädring av existerande typer eller av någon ny typ med 461 969 fjädrar gjorda av stål och/eller av gummi. 4 “wAs implied by what has been described above, the device according to the invention can easily be installed in any type of primary suspension of existing types or of any new type with 461,969 springs made of steel and / or of rubber. 4 “w
