Description

Anordning for fjærende opphengning av vognkassen, Device for spring suspension of the wagon body,

fortrinnsvis på skinnekjøretøyer. preferably on rail vehicles.

Foreliggende oppfinnelse angår en anordning for fjærende opphenging av vognkassen, fortrinsvis på skinnekjøretøyer, for å motvirke krengninger, når vognen under gang gjennom kurver utsettes for massekrefter i sideretningen. The present invention relates to a device for spring suspension of the wagon body, preferably on rail vehicles, to counteract tilting, when the wagon is exposed to mass forces in the lateral direction while traveling through curves.

Som bekjent hviler vognkassen nor-malt på fjærende elementer og disse hviler igjen på lagerbokser, som er anbragt på hjulakslene. Når en vogn passerer gjennom en kurve, vil passasjerene utsettes for side-akselerasjoner på grunn av opptredende massekrefter. Det har vært forsøkt å elimi-nere virkningen av disse massekrefter ved å dosere banen, men da en dosering ikke kan utføres slik ta den passer både for et langsomtgående godstog og et rasktgående persontog, er det bare oppnådd en viss forbedring. Hertil kommer at med den ut-førelse av den fjærende opphenging som nå anvendes, vil massekreftene gi kassen en tendens til å krenge, d. v. s. å stille seg på skrå utover. Denne tendens tiltar i styrke jo mykere fjæringen er. En sådan krenging øker den sideakselerasjon som påvirker passasjerene. For at reisen gjennom kurven skal være uten merkbart ube-hag, kreves ta sideakselerasjonen ikke overstiger en viss størrelse. Hvis det altså kan forhindres at vognen krenger, kan den føres frem med høyere hastighet gjennom kurven. As you know, the carriage body normally rests on spring elements and these in turn rest on bearing boxes, which are placed on the wheel axles. When a carriage passes through a curve, the passengers will be subjected to lateral accelerations due to the acting mass forces. Attempts have been made to eliminate the effect of these mass forces by dosing the track, but as dosing cannot be carried out in such a way that it is suitable for both a slow-moving goods train and a fast-moving passenger train, only a certain improvement has been achieved. In addition, with the design of the sprung suspension that is now used, the mass forces will give the box a tendency to tilt, i.e. to position itself at an angle outwards. This tendency increases in strength the softer the suspension. Such heeling increases the lateral acceleration affecting the passengers. In order for the journey through the curve to be without noticeable discomfort, the lateral acceleration must not exceed a certain amount. If the cart can therefore be prevented from overturning, it can be moved forward at a higher speed through the curve.

Det er ganske visst kjent ved toakslet It is certainly known for the two-axle

boggi for skinnekjøretøyer med fjærende opphengning av vognkassen, ved hvilken man vil hindre vognkassens sidebevegelse og krengning ved hjelp av torsjonsstaver, bogie for rail vehicles with spring suspension of the carriage body, which will prevent lateral movement and tilting of the carriage body by means of torsion bars,

som er anordnet slik i forhold til støtfjærer som bærer en til anordningen hørende boggiramme at den geometriske akse i hver torsjonsstav befinner seg i samme verti-kalplan som den geometriske akse for den støtfjær som ligger nærmest torsjons-staven. Til forskjell fra disse anordninger består foreliggende oppfinnelse vesentlig i at vognkassen er forbundet med hjulakslene ved hjelp av pendelelementer og lenkeelementer hvorav det førstnevnte har sine svingepunkter fastlagt på vedkommende hjulaksel og hvor det i de sistnevnte inngår ett eller flere torsjonsfjærelementer som er fast forbundet med vognkassen på slik måte at disse f jærelementer spennes når vognkassen krenger til den ene eller andre siden og derved motvirker denne bevegelse hvorved krengninger helt eller i det aller nærmeste helt elimineres når vognen ved kjøring gjennom kurve utsettes for massekrefter i sideretningen. Herved oppnås en betraktelig forbedring i ovennevnte henseende. Likeoverfor den nevnte anordning med støtfjærer oppnås bl. a. at slike blir unødvendige ved foreliggende anordning. which is arranged in such a way in relation to shock springs that carry a bogie frame belonging to the device that the geometric axis of each torsion bar is in the same vertical plane as the geometric axis of the shock spring which is closest to the torsion bar. In contrast to these devices, the present invention essentially consists in that the carriage body is connected to the wheel axles by means of pendulum elements and link elements, the former of which has its pivot points fixed on the relevant wheel shaft and where the latter includes one or more torsion spring elements which are firmly connected to the carriage body on in such a way that these spring elements are tensioned when the carriage tilts to one side or the other and thereby counteracts this movement whereby tilting is completely or very nearly completely eliminated when the carriage is exposed to mass forces in the lateral direction when driving through a curve. This achieves a considerable improvement in the above-mentioned respect. Directly opposite the aforementioned device with shock springs, the a. that such become unnecessary with the present arrangement.

En utførelsesform for oppfinnelsen er vist på vedføyete tegninger i fire figurer, hvorav fig. 2-4 er utført i større målestokk enn fig. 1. An embodiment of the invention is shown in the attached drawings in four figures, of which fig. 2-4 are made on a larger scale than fig. 1.

Fig. 1 viser et tverrsnitt gjennom Fig. 1 shows a cross section through

kjøretøyet. the vehicle.

Fig. 2 viser et planriss av detaljer som Fig. 2 shows a plan view of details which

ligger under linjen II i fig. 1. lies below line II in fig. 1.

Fig. 3 viser de samme detaljer sett fra den ene side, nemlig fra venstre i fig. 1. Fig. 4 viser et snitt etter linjen IV-IV i fig. 1. Fig. 3 shows the same details seen from one side, namely from the left in fig. 1. Fig. 4 shows a section along the line IV-IV in fig. 1.

I fig. 1 er vognens overbygning betegnet 1, mens den ramme som den hviler på er betegnet 2, hjulene 3 og hjulaksel-forbindelsen 4 samt selve akseltappene for hjulene 5. Setene i vognen er betegnet 6 og en dør 7. In fig. 1, the carriage's superstructure is designated 1, while the frame on which it rests is designated 2, the wheels 3 and the wheel-axle connection 4 as well as the axle studs for the wheels themselves 5. The seats in the carriage are designated 6 and a door 7.

I henhold til oppfinnelsen er den kjøretøyramme 2 som bærer vognkassen hengt opp på hjulakslene ved hjelp av den anordning som nå skal beskrives. Da denne opphengningsanordning forutsettes å være anordnet i forbindelsen mellom ramme og hjulaksel på de steder hvor den trenges, men er av en og samme beskaffenhet på hvert slikt sted, skal den beskrives bare ved en akselende. En lagerhylse eller lager-boks 8 som sitter på akselenden, hensiktsmessig utenfor hjulet, bærer et feste 9 for to pendelelementer 10, som er lagret på hyer sin bolt 12 som sitter i festet. Gjennom et lenkeelement 13 er pendelelementet forbundet med rammen over en spindel e. 1. 14, som er festet i rammen. På denne spindel er det tredd inn en torsjonsfjær 15, f. eks. av gummi. Fjæren er klemt inn mellom de to halvdeler av en todelt lager-eller navhylse som hører til lenken. Denne kan trekkes mere eller mindre til mot torsjonsfjæren og denne igjen mot spindelen ved hjelp av skruer 16 i lagerhylsen. Ved hjelp av denne anordning av torsjonsfjæren vil lenken by en viss motstand mot dreiebevegelser om spindelen. Til hver pendelelement hører en slik lenk og ved hvert opphengningspunkt finnes to pendler og to lenker i henhold til denne utførelses-form. Anordningen virker på følgende måte: Massekreftene P, som angriper i tyng-depunktet T for kassen 1, søker dels å velte kassen, dels å føre den i sideretning. Hvis nå kassen føres f. eks. mot venstre, vil også pendelelementet 10 svinge mot venstre om sitt øvre faste festepunkt. Torsjonsfjæren 15 blir da spent. Ved skråstillingen synker videre fjæren nedover og spennes derved ytterligere. Selvsagt vil samtidig pendelelementet og fjæren på høyre side av kassen bevege seg fra de stillinger de inntar ved kjøring på rett linje. Ved å analysere systemet for hver enkelt konstruksjon kan fjærene gis en sådan karakteristikk at skråstillingen helt siler på det nærmeste helt elimineres. En fordel ved anordningen er at det fjærende element er fast forbundet med kassen. Herved vil fjæren selv tilhøre den fjærende vekt, og det er kjent at det alltid søkes å oppnå en så liten ikke fjæret vekt som mulig. According to the invention, the vehicle frame 2 which carries the carriage body is suspended on the wheel axles by means of the device that will now be described. As this suspension device is assumed to be arranged in the connection between the frame and the wheel axle in the places where it is needed, but is of one and the same nature in each such place, it shall be described only at one axle end. A bearing sleeve or bearing box 8 that sits on the axle end, conveniently outside the wheel, carries a mount 9 for two pendulum elements 10, which are stored on hyer's bolt 12 that sits in the mount. Through a link element 13, the pendulum element is connected to the frame via a spindle e. 1. 14, which is fixed in the frame. A torsion spring 15 is threaded onto this spindle, e.g. of rubber. The spring is sandwiched between the two halves of a two-piece bearing or hub sleeve belonging to the link. This can be pulled more or less towards the torsion spring and this again towards the spindle by means of screws 16 in the bearing sleeve. By means of this arrangement of the torsion spring, the link will offer a certain resistance to turning movements about the spindle. Such a link belongs to each pendulum element and at each suspension point there are two pendulums and two links according to this embodiment. The device works in the following way: The mass forces P, which attack at the center of gravity T for the crate 1, seek partly to overturn the crate and partly to move it sideways. If now the cash register is entered e.g. to the left, the pendulum element 10 will also swing to the left about its upper fixed attachment point. The torsion spring 15 is then tensioned. In the inclined position, the spring further sinks downwards and is thereby further tensioned. Of course, at the same time the pendulum element and the spring on the right side of the box will move from the positions they occupy when driving in a straight line. By analyzing the system for each individual construction, the springs can be given such a characteristic that the slant position completely strainers are almost completely eliminated. An advantage of the device is that the spring element is firmly connected to the box. In this way, the spring itself will belong to the sprung weight, and it is known that it is always sought to achieve as small an unsprung weight as possible.

Den oppfinnelsestanke som det er gitt et eksempel på ovenfor kan tilpasses også ved landeveisbusser og boggier i alminne-lighet for å hindre krengning, og blir ved sin enkle konstruksjon sammenlignet med eldre anordninger for fjærende forbindelse mellom understell og vognkasse lett å ut-føre, lett å montere og også holdbar ved at den ikke omfatter ømtålelige deler. I ste-det for en gummihylse kan det anvendes en skrufjær eller torsjonsstav hvis ender er festet på hensiktsmessig måte. The inventive idea of which an example has been given above can also be adapted to road buses and bogies in general to prevent overturning, and due to its simple construction compared to older devices for a springy connection between the undercarriage and carriage body is easy to carry out, easy to assemble and also durable in that it does not include sensitive parts. Instead of a rubber sleeve, a coil spring or torsion bar can be used, the ends of which are attached in an appropriate manner.
