Description

Vrtilna ogrodja in večosni tekalni mehanizmi tirničnih vozil so običajno uležajenl s pomočjo centrično nameščenega ležaja pod vagonsko karoserijo. Pri tem se zlasti pri vožnjah v krivini pojavlja različna kolesna obtežba vrtilnih ogrodij tekalnih mehanizmov. Ta različna obremenitev koles, lahko privede do tega, da so kolesa notranje krivine ali kolesa vrtilnega ogrodja, ki stojijo na strani, ki je nasproti povišanja tračnice, tako malo obremenjena, da varnost proti iztirjenju ni več zagotovljena.The rolling stock and the multi-axle rolling stock of the rolling stock are usually mounted by means of a centrally mounted bearing under the wagon body. Especially when cornering, there is a different wheel load on the running gears. This different load on the wheels may cause the wheels of the inner curvature or the wheels of the bogie to stand on the side opposite the rail elevation so low that the derailment is no longer guaranteed.

Pred izumitelja se torej postavlja tehnični problem s kakšnimi konstrukcijskimi ukrepi odpraviti ali vsaj zmanjšati različno obremenitev koles vrtilnega ogrodja tirničnih vozil, kar bo pri predmetu izuma doseženo z uporabo bočnih elastičnih podpor nameščenih med karoserijo vagona in vrtilnim ogrodjem tirničnega vozila.Therefore, the inventor is faced with the technical problem of what design measures to eliminate or at least reduce the different wheel load of the rolling stock of the rolling stock, which will be achieved with the use of lateral elastic supports placed between the wagon body and the rolling stock of the rolling stock.

* Stanje tehnike* The state of the art

Iz prakse so znane izvedbe pri katerih je pri vrtilnih ogrodjih, ki so centrično vodena s pomočjo vrtilne ponve, vrtilnega venca, vodilnega tečaja ali sličnega namestijo med vagonsko karoserijo in okvir vrtilnega ogrodja elastične opore, ki omogočajo zasuk vrtilnega ogrodja in ki s pomočjo vmes vstav( ljenih vzmetnih drsnih delov omogočajo relativna gibanja med karoserijo vagona in vrtilnimi ogrodji, tako da dobimo v bistvu enakomerno obtežbo s karoserijo vagona in da se prepreči nezažeI lena prevelika tlačna razbremenitev posameznih koles. Pritisna sila vzmetnih drsnih delov in s tem delna razbremenitev vodilnih sredstev vrtilnega ogrodja se lahko spremeni z odgovarjajočo prednapetostjo vzmetnih drsnih delov.In practice, embodiments are known in which, for rotary frames centrally guided by a rotating pan, a rotating pivot, a guide hinge or the like, elastic supports are provided between the wagon body and the pivot frame, which allow rotation of the rotary frame and which by means of insertions (Suspended sliding parts allow for relative movements between the wagon body and the pivot frames, thus giving a substantially uniform load to the body of the wagon and preventing undesirable undue pressure on the individual wheels. the frame can be modified by the appropriate prestressing of the sliding components.

Pri znanih elastičnih oporah je praviloma predvidena trdno nameščena drsna plošča, ki se opira ob ovzmeteno drsno ploščo. Ovzmetena drsna plošča je pri tem pri navedenih znanih izvedbah opremljena z vzmetnimi elementi, ki v omejenem obsegu omogočajo vertikalni vzmetni pomik navedene elastične drsne plošče. Z namestitvijo vzmetnega elementa za vertikalno podajnost drsnega dela je tu potrebna namestitev dodatnih vodil, da bi bil drsni del pri relativnih gibanjih vrtljivega ogrodja v odnosu na karoserijo vagona točno voden.In the case of known elastic supports, as a rule, a rigidly mounted sliding plate is provided which rests against a suspended sliding plate. In the above known embodiments, the spring sliding plate is provided with spring elements which, to a limited extent, allow the vertical spring displacement of said elastic sliding plate. By installing a suspension element for the vertical support of the sliding part, additional guides are needed here to ensure that the sliding part is precisely guided relative to the wagon body relative to the wagon body.

Iz patentne literature so iz zahodno nemških odobrenih patentnih prijav DE-AS i 926 298, 2 457 907 i¹¹ 2 200 6J0 znane izvedbe, ki so podobne predhodno opisanim iz prakse znanim konstruk cijam.From the patent literature, embodiments similar to those previously known in the art are known from the West German patent applications DE-AS i 926 298, 2 457 907 and ¹¹ 2 200 6J0.

Iz zahodno nemške objavljene patentne prijave DE-OS 2 527 504 je znana izvedba listnate vzmeti, ki je od sredine svoje dolžine proti obema koncema naleganja izvedena s parabolično se zmanjšujočo višino prečnega preseka. Pri tem so na koncih vzmeti z zakrivljenjem materiala navzdol izoblikovana ležajna očesa.From the West German patent application DE-OS 2 527 504, a known embodiment of a leaf spring is made from the middle of its length towards both ends of the bearing with a parabolic decreasing cross-sectional height. In this case, the ends of the springs with the curvature of the material are downwardly shaped bearing eyes.

Pomanjkljivost predhodno opisanih znanih namestitev elastičnih opor so v tem, da so praviloma zelo drage ali pa povzročajo težave pri postavljanju karoserije vagona na vrtljiva ogrodja.A disadvantage of the previously known known mounting of elastic supports is that they are generally very expensive or cause problems in placing the wagon body on rotating frames.

Nadaljnja pomanjkljivost znanih izvedb je v tem, da so vzmetni drsni deli tudi v obremenjenem stanju opremljeni z vodoravno vzdolžno zračnostjo. Zaradi tega pri vožnji naravnost manjka zaželeni zadrževalni učinek vrtenja stranskih drsnih delov, tako da vrtilna ogrodja pri višjih hitrostih kažejo nagnjenost k zibanju.A further disadvantage of the known embodiments is that the spring sliding parts are also provided with horizontal longitudinal clearance in the loaded state. As a result, the drive naturally lacks the desired retention effect of rotating the lateral sliding parts, so that the rotating frames at higher speeds show a tendency to rock.

Opis rešitve tehničnega problema s primeri izvedbe in seznamom slikDescription of a solution to a technical problem with examples of implementation and a list of images

Rešitev predhodno obravnavanega tehničnega problema je v tem, da pri bočnih elastičnih podporah karoserije vagona oz. tirničnega vozila napram njegovemu vrtilnemu ogrodju ali tekalnemu mehanizmu - uvodoma navedene vrste odpravi ali vsaj zmanjša različno obtežbo koles, kar je doseženo z bočnimi elastičnimi podporami med karoserijo vagona in vrtilnim ogrodjem tirničnega vozila - po izumu, pri čemer je vsakokratna bočna elastična podpora konstruirana brez dragih konstrukcijskih delov in omogoča da se doseže direktno delujoče zaviranje vrtenja vrtilnega ogrodja napram karoseriji vagona.The solution to the previously discussed technical problem is that with the lateral elastic supports of the wagon body or. of the rolling stock against its bogie or running gear - of the above mentioned type eliminates or at least reduces various wheel loads, which is achieved by lateral elastic supports between the wagon body and the rolling stock of the rail vehicle - according to the invention, whereby the lateral elastic support is constructed without expensive structural components and allows direct acting braking of the rotation of the bogie against the body of the wagon.

Rešitev tehničnega problema je v tem, da je trdno nameščeni drsni del bočne elastične podpore med karoserijo vagona in vrtilnim ogrodjem - kotznano - izveden z ravno drsno ploskvijo, vsakokratni vzmetni drsni sklop v smislu izuma pa ima nekoliko konveksno drsno ploskev, ki jo oblikuje zunanja površina listne vzmeti, ki pripada vzmetnemu drsnemu sklopu, po izumu. Pri tem je vsakokratni vzmetni drsni sklop izveden iz podolgovate osnovne plošče za pritrditev bodisi na vrtilno ogrodje ali na karoserijo železniškega vagona, pri čemer sta na enem koncu osnovne plošče pritrjena dva ležaja v katerih je s pomočjo sornika zgibno uležajen v uho zapognjeni konec listne vzmeti, ki se z nasprotnim nekoliko ukrivljenim koncem drsno opira na drsni blok opornega čevlja, ki je pritrjen na nasprotni konec osnovne plošče, pri čemer _ baje v sredini dolžine osnovne plošče oz. listne vzmeti nameščen na osnovno ploščo pritrjeni omejevalnik nad katerim poteka listnata vzmet, ki pri elastični deformaciji listnate vzmeti pri pritisku s strani karoserije vagona naleze na omejevalnik.The solution to the technical problem is that the rigidly mounted sliding portion of the lateral elastic support between the body of the wagon and the pivot frame is indented - with a flat sliding surface, and each spring sliding assembly according to the invention has a slightly convex sliding surface formed by the outer surface leaf springs belonging to the spring sliding assembly according to the invention. In this case, the respective spring sliding assembly is made of an elongated base plate for attachment to either the bogie or the body of a railway wagon, with two bearings fixed at one end of the base plate in which the end of the leaf spring is articulated in the ear by means of a bolt, which, with the opposite slightly curved end, slides on the sliding block of the support shoe, which is fixed to the opposite end of the base plate, with _ being in the middle of the length of the base plate or. a leaf spring mounted on the base plate a restraint above which a leaf spring extends, which, upon elastic deformation of the leaf spring, enters the restraint when pressed by the wagon body.

S to konstrukcijo se na smotrn način izoblikuje drsna naležna ploskev vsakokratnega vzmetnega sklopa z zunanjo površino listne vzmeti, ki je obrnjena k protiopori l - t.j. k trdno nameščenem drsnem delu (ki je trdno pritrjen bodisi na karoserijo ali na vrtilno ogrodje tirničnega vozila).With this construction, the sliding bearing surface of the respective spring assembly with the outer surface of the leaf spring facing the counter-support l - i.e. to a rigidly mounted sliding part (which is firmly attached either to the body or to the rolling stock of the rail vehicle).

S tem je preprečena potreba po dragih konstrukcijskih delih. S predhodno opisanim uležajenjem ušesa listne vzmeti je dosežena zgibna pritrditev brez vzdolžne zračnosti z enostavnimi sredstvi. Listna vzmet ima presek v vzdolžni smeri parabolično izoblikovan, pri čemer se višina preseka približno od sredine njene dolžine zmanjšuje proti obema njenima oporama. S pomočjo paraboličnega izoblikovanja poteka debeline listne vzmeti je pri določeni konstrukcijski dolžini zagotovljena maksimalna elastičnost vzmetnega drsnega sklopa. Nadaljnja prednost paraboličnega izoblikovanja listne vzmeti vzmetnega drsnega sklopa je v tem, da listno vzmet lahko predhodno nastavimo, da bi s tem dosegli večjo obremenitev pri isti kvaliteti materiala.This eliminates the need for expensive structural work. The previously described bearing of the leaf spring ear achieves articulated attachment without longitudinal play with simple means. The leaf spring has a longitudinal cross-section in a parabolic fashion, with the cross-sectional height decreasing from about the middle of its length toward both of its supports. With the help of parabolic shaping of the leaf spring thickness, the maximum elasticity of the spring sliding assembly is ensured at a certain design length. A further advantage of the parabolic design of the leaf spring of a spring sliding assembly is that the leaf spring can be pre-adjusted in order to achieve greater loading at the same material quality.

Z uležajenjem listne vzmeti v vodoravnem ležajnem ušesu s pomočjo sornika^je celo pri zračnosti v ležajnem ušesu doseženo uležajenje brez kakršnekoli vzdolžne zračnosti listne vzmeti. V zvezi s stalno delujočo prednapetostjo in z njo ustvarjenim ploščinskim pritiskom listne vzmeti na trdno pritrjenem opornem čevlju se že pri najmanjših zasučnih gibanjih vrtljivega ogrodja nasproti karoseriji vagona ustvari določen moment brez kakršnegakoli prostega hoda.By mounting the leaf spring in a horizontal bearing with the help of a bolt ^, even with the clearance in the bearing eye, the bearing is achieved without any longitudinal clearance of the leaf spring. With regard to the continuous acting prestress and the resulting surface pressure of the leaf spring on a firmly attached support shoe, a certain torque is created without any idling in the slightest rotational motion of the rotating frame against the body of the wagon.

Z izbiro prednapetosti in torne vrednosti drsne ploskve se lahko doseže optimalno zaviranje vrtenja, ki vse do visokih hitrosti zadržuje oz. zavira nestabilnost (zibanje) vrtilnega ogrodja in ki istočasno za tek v loku vzdržuje še zadosti majhne vodilne sile na kolesnem obodu.By selecting the prestress and friction value of the sliding surface, optimal rotation inhibition can be achieved, which holds up to high speeds at high speeds. it inhibits the rocking instability (rocking) of the bogie and maintains at the same time sufficient small steering forces at the wheel circumference for running in the bow.

Prosti konec listne vzmeti nalega^ voden vzdolžno pomično in s stransko zračnostjo na drsnem bloku opornega čevlja. S tem naleganjem prostega konca listne vzmeti na drsnem bloku je pri vzmetnem posedanju listne vzmeti omogočen prosti vzdolžni pomik njenega prostega konca.Free end of leaf spring ^ guided longitudinally movable and with lateral play on the sliding block of the support shoe. This alignment of the free end of the leaf spring on the sliding block enables the free longitudinal movement of its free end when springing the leaf spring.

Izum bomo podrobno obrazložili na osnovi izvedbenega primera in pripadajočih načrtov, v katerih kaže: sl. 1 stranski pogled vsakokratnega vzmetnega drsnega sklopa bočne elastične podpore po izumu,delno prikazan v prerezu sl. 2 tloris vzmetnega drsnega sklopa bočne elastične podpore po sl . 1 , sl. 3 namestitev bočnih elastičnih podpor po izumu med karoserijo vagona in izvrtilnim ogrodjem na tovornem železniškem vagonu.The invention will be explained in detail on the basis of an embodiment and accompanying plans, in which: FIG. 1 is a side view of the respective spring sliding assembly of the lateral elastic support according to the invention, partly shown in cross-section of FIG. 2 is a plan view of a spring sliding assembly of lateral elastic support according to FIG. 1, FIG. 3 the installation of lateral elastic supports according to the invention between the wagon body and the bogie on a freight wagon.

Kot je razvidno iz sl. 1 in 2 vsakokratni vzmetni drsni sklop 1 sestoji iz podolgovate osnovne plošče 7 za pritrditev na vrtilno ogrodje. Na enem koncu osnovne plošče sta pritrjena dva ležaja 4, v katerih je nameščen z glavo 3 izvedeni sornik 2. Na tem sorniku 2 je zasučno uležajeno uho 1” listne vzmeti 1a, katere prosti nalahno zapognjeni konec 1’ prosto nalega na k drsnem bloku 5” opornega čevlja 5. Oporni čevelj 5;sestoji iz podnožnega bloka 5\ ki je pritrjen na osnovno ploščo 7, in iz na podnožnem bloku 5’ nameščenega drsnega bloka 5”. Na čelno ploskev drsnega bloka 5” je z zvarom pritrjena čelna plošča 5’”, ki je s pomočjo vijakov 8 pritrjena na podnožni blok 5’. Na bočnih oz. vzdolžnih straneh drsnega bloka 5” sta pritrjeni stranski vodili 5a.Na sredini dolžine osnovne plošče Jje pritrjena podnožna plošča 6” cilindričnega čepa 6’ omejevalnika 6 listnate vzmeti 1a. V načrtih sl. 1 in 2 ( ni prikazan z ravno drsno ploskvijo izvedeni trdno pritrjeni drsni del ob katerega nalega zunanja v bistvu konveksno izoblikovana drsno naležna ploskev 1a’ listne vzmeti 1a.Figures 1 and 2 show the detailed construction of the spring sliding assembly 1 in the outline and the plan. As can be seen from FIG. 1 and 2, each spring assembly 1 consists of an elongated base plate 7 for attachment to the pivot frame. At one end of the base plate, two bearings 4 are mounted, in which a head 3 is provided with a head 3. This pin 2 has a pivotably mounted ear 1 ”of a leaf spring 1a, whose free, slightly bent end 1 'rests freely on the sliding block 5. "Support shoe 5. The support shoe 5; consists of a base block 5 \ attached to the base plate 7 and a sliding block 5" mounted on a base block 5 '. The front face of the sliding block 5 ”is welded to the front face plate 5 '', which is fixed to the base block 5 'by screws 8. On the side or. the side guides 5a are attached along the sides of the sliding block 5 ". At the middle of the length of the base plate, the base plate 6" of the cylindrical pin 6 "of the limiter 6 of the leaf spring 1a is fastened. In the plans of FIG. 1 and 2 (not shown by a flat sliding surface, a rigidly fixed sliding portion adjacent to the substantially convexly sliding bearing surface 1a 'of the leaf spring 1a.

Iz sl. 3 je razvidna namestitev bočnih elastičnih podpor med karoserijo vagona in vrtilnim ogrodjem tirničnega vozila, obstoječih iz drug nasproti drugim ležečih trdno pritrjenih drsnih delov in vzmetnih drsnih sklopov 1.From FIG. 3 shows the positioning of the lateral elastic supports between the wagon body and the rolling stock of the rail vehicle, existing from each other, firmly attached sliding parts and suspension sliding assemblies 1.

Omenjeni z ravno drsno ploskvijo izvedeni trdno pritrjeni drsni del (ob katerega nalega konveksno izoblikovana drsna naležna ploskev 1a’ listne vzmeti 1a) obstoji iz vodoravno nameščene - na svoji spodnji strani ravne plošče, katere drsna ploskev je eventualno lahko opremljena z dodatno oblogo z visoko obrabno trdnostjo ali z nizkim tornim koeficientom. Izoblikovanje tega trdno pritrjenega drsnega dela (oz. drsne protiopore), na katerega nalega drsna naležna ploskev la’ listne vzmeti 1a, ki pripada vzmetnemu drsnemu sklopu 1, pa ni predmet pričujočega izuma, zaradi česar ga ne bomo podrobneje opisovali.Said with a flat sliding surface, a rigidly fixed sliding portion (supported by a convexly sliding bearing surface 1a 'of the leaf spring 1a) consists of a horizontally mounted flat plate on its underside, the sliding surface of which may optionally be provided with an additional high-wear pad strength or low friction coefficient. The design of this rigidly fixed sliding part (or sliding protopore), to which the sliding bearing surface of the leaf spring 1a belonging to the spring sliding assembly 1, is not, is not an object of the present invention, which will not be described in more detail.

Listna vzmet la je v svojem vzmetno delujočem področju izvedena s paraboličnim presekom pri katerem se višina preseka zmanjšuje proti obema navedenima koncema.The leaf spring la is made in its spring-acting region with a parabolic cross-section in which the height of the cross-section decreases towards both ends.

Vzmetni drsni sklop 1 je prednostno nameščen na vrtilnem ogrodju ali na tekalnem mehanizmu timičnega vozila, medtem ko je trdno pritrjeni drsni del pritrjen na karoseriji vagona. Za zmanjšanje specifičnega površinskega pritiska se drsna naležna ploskev 1a’ listne vzmeti 1a vzmetnega drsnega sklopa 1 na sredini njegove dolžine na kratkem po dročju lahko izoblikuje ravno, ne da bi bila s tem oškdovana vzmetna karakteristika vzmetnega drsnega sklopa 1.The suspension sliding assembly 1 is preferably mounted on a rotary frame or on a running gear of a thymic vehicle, while a rigidly mounted sliding portion is attached to the body of the wagon. In order to reduce the specific surface pressure, the sliding bearing surface 1a 'of the leaf spring 1a of the spring sliding assembly 1 in the middle of its length in a short span may be formed straight without damaging the spring characteristic of the spring sliding assembly 1.

-11-SUMMARY

The object of the invention is the lateral elastic supports between the wagon body and the rolling stock of the rail vehicle, which have against each other, firmly fixed sliding parts and spring sliding assemblies 1, which solve the technical problem of eliminating or at least reducing the various loads of the wheels of the rotating frame.

Each firmly fixed sliding part is fixed to the wagon body and to it is mounted opposite the spring sliding assembly 1 on the rolling stock of the rail vehicle.

The rigidly mounted sliding part has a flat sliding surface. The spring sliding assembly (1) is provided with an approximately convex contact sliding surface (1a *) and consists only of at its ends without a longitudinal clearance of the leaf spring. The leaf spring forms a non-movable sliding surface (1a *) facing its fixed sliding part to support the non (movable sliding part).

By mounting the fixed sliding parts on the suspension sliding assembly 1, a clearly effective rotation restraint is achieved between the wagon body ^ and the rotary frame, which prevents the transverse swinging and / or rolling. oscillation of the wagon around the longitudinal axis of the wagon at higher speeds.
