Opfindelsen angår en automatisk rangerkobling af den i krav l's indledende del angivne art.The invention relates to an automatic rank coupling of the kind specified in the preamble of claim 1.
Fra DE-OS 27 45 158 kendes en automatisk rangerkobling, ved 5 hvilken der på begge sider af fangemunden strækker sig en næse indad, som i en retning eller begge retninger er svingelig i et vandret plan og ved hjælp af en fjeder fastholdes i den indsvingede stilling, medens den under indføring i fangemunden værende trækhage trykker de svingelige næser udad, hvorpå de 10 efter trækhagens indføring igen vender tilbage til udgangsstillingen og således fastlåser og fastholder trækhagen i fangemunden, hvorefter koblingsoperationen er afsluttet. En ulempe ved denne kobling består dels deri, at såfremt den næserne i indsvinget stilling trykkende fjeder falder ud, vil 15 det ikke længere være muligt at opnå sammenkobling, da de under indføringen af trykhagen til åbnesti 11ing trykkede næser ikke mere vil gå tilbage til koblingsstilling, dels at en fastklemning af de svingelige næser som følge af ydre påvirkninger, såsom smuds, is eller lignende, vil forhindre, at næ-20 serne igen bevæger sig tilbage til lukkestilling, så at der heller ikke i dette tilfælde yderligere kan foretages sammenkobl i ng.From DE-OS 27 45 158 there is known an automatic ranger coupling, at which 5 on both sides of the catch mouth extends a nose inwards which in one direction or both directions is pivotable in a horizontal plane and is held in the pivoted by a spring position, while the towbar during insertion into the catch mouth presses the pivotal noses outwardly, after which, after the introduction of the towbar, the 10 returns to the initial position and thus locks and retains the towbar in the catch mouth, after which the coupling operation is completed. A disadvantage of this coupling partly consists in the fact that if the noses in the swivel position depressing spring fall out, it will no longer be possible to obtain coupling, since during the introduction of the pressure hose to open pressure 11 nozzles will no longer return to coupling position secondly, that clamping of the pivotal noses due to external influences, such as dirt, ice or the like, will prevent the noses from moving back to the closing position so that in this case no further interconnection can be made in ng.
Yderligere kendes fra DE-OS 32 04 406 en rangerkobling, ved 25 hvilken to om en fælles akse svingelige tangvægtstænger danner koblingsøjet, og idet hele den tangvægtstængerne bærende koblingsdel er forskydelig i en sådan grad, at denne del ved hjælp af hager forbindes med tilkoblingsstykket. Denne kobling har den ulempe, at den er forholdsvis kostbar, og at sammen-30 låsningen mellem koblingsdelen og tilkoblingsstykket kræver et forholdsvis kraftigt stød af det påkørende køretøj.Furthermore, from DE-OS 32 04 406 there is known a ranking coupling, at which two pivot forceps forming a joint axis form the coupling eye, and the whole coupling part carrying the pair of forceps bars is displaceable to such an extent that this part is connected to the connection by means of hooks. This coupling has the disadvantage that it is relatively expensive and that the locking between the coupling part and the coupling piece requires a relatively strong impact of the moving vehicle.
Fra US-patentskrift nr. 1.067.384 kendes en automatisk rangerkobling, der lukkes ved indføring af en hanpart imellem tang-35 vægtstænger eller kæber. Kæberne er forsynet med et anslag, som hanparten påvirker, hvorved kæberne presses sammen omkring denne. Når kæberne er lukket helt sammen føres en låseblok indUS Patent No. 1,067,384 discloses an automatic ranger coupling which is closed by inserting a male part between forceps or jaws. The jaws are provided with an impact that the male part influences, thereby compressing the jaws around it. When the jaws are fully closed, a locking block is inserted

Ved åbning trækkes låseblokken ud af indskæringen og kæberne kan åbnes, og hanparten kan trækkes ud af kæberne igen.2 between the extension of the jaws behind the pivots, thereby preventing the jaws from opening. Upon opening, the locking block is pulled out of the notch and the jaws can be opened and the male part can be pulled out of the jaws again.

Formålet med opfindelsen er at tilvejebringe en rangerkobling, som udviser god sikkerhed for at sammenkoblingen gennemføres.The object of the invention is to provide a rank coupling which shows good security for the coupling to be carried out.
Dette er ifølge opfindelsen opnået ved den i krav l's kende-10 tegnende del angivne udformning.This is achieved according to the invention by the embodiment of claim 1.
Herved opnås at der tilvejebringes en rangerkobling, som udviser god sikkerhed for at sammenkoblingen gennemføres. Dette skyldes især, at de to tangvægtstænger er således koblet sam-15 men, at der til enhver tid udføres en tvunget synkron bevægelse, selv om den trækhage, som skal indgribe med rangerkoblingen ikke er nøjagtigt centreret i forhold til tangvægtstængerne. Rangerkoblingen har vist sig også at fungere tilfredsstillende sammen med trækhager med forskellig tykkelse og form, 20 og selv om trækhagen kun rammer imod den ene af tangvægtstængerne.This results in the provision of a ranking coupler which shows good assurance that the coupling is carried out. This is mainly because the two forceps bar are thus coupled together, while a forced synchronous movement is performed at all times, even though the towbar which is to engage the ranger coupling is not exactly centered on the forceps bar. The ranger coupling has also been found to work satisfactorily with drawbar of different thickness and shape, 20 and although the towbar only hits against one of the forceps.
Rangerkoblingen ifølge opfindelsen har den fordel, at den kan fremstilles ud fra forholdsvis få elementer, og at alle fejl-25 muligheder nærmest er udelukkede. Koblingen virker således endnu sikkert, selv om alle fjedre skulle være knækkede. Således kan trækhagen også trækkes bort fra koblingsstilling, selv om de fjedre, der trækker tangvægtstængerne til åben stilling, er knækkede, idet tangvægtstængerne, når de udsættes 30 for træk fra trækhagen, automatisk åbnes. På den anden side kan kun et yderligere brud på en tangvægtstang åbne koblingen, når låseblokken er indsat. Yderligere kan låseblokken være således anbragt, at den alene som følge af tyngdekraften bevæger sig til låsestilling.The ranking coupling according to the invention has the advantage that it can be manufactured from relatively few elements and that all error options are virtually excluded. The clutch thus still works safely, even though all springs should be broken. Thus, the towbar can also be pulled away from the coupling position, although the springs which pull the forceps to the open position are broken, when the forceps, when exposed to the towbar, are automatically opened. On the other hand, only a further break of a forceps bar can open the clutch when the locking block is inserted. Further, the locking block may be positioned such that it moves to the locking position solely due to gravity.
En udførelsesform for en rangerkobling ifølge opfindelsen vil i det følgende blive nærmere beskrevet under henvisning til tegningen, på hvilken 35 3An embodiment of a ranger coupling according to the invention will be described in the following with reference to the drawing, in which
DK 160242 BDK 160242 B
fig. 1 viser koblingen, set fra siden, delvis i snit, og fig. 2 et snit efter linien 11 — 11 i fig. 1.FIG. 1 is a sectional side view of the coupling; and FIG. 2 is a sectional view taken along line 11 - 11 of FIG. First
5 Den viste kobling har en bæreplade 11, på hvis forside der er anbragt en fangemund 12. To tangvægtstænger 13 og 14 er svin-gelige om lodrette bolte 15 på bærepladen 11. Tangvægtstangen 14 er udformet med et anslag 16 for en trækhage, der skal tilkobles. En tværstang 17 er dels på i og for sig kendt måde 10 svingeligt forbundet med en bolt 18 på tangvægtstangen 14 og med en bolt 19 på tangvægtstangen 13, så at tangvægtstangen 14's bevægelser tvangsmæssigt overføres til tangvægtstangen 13 og de to vægtstænger samtidigt udfører de fornødne tanglåse-og tangåbnebevægelser. Bevæges således tangvægtstangen 14 til 15 åben stilling, vil tangvægtstangen 13 gennem tværstangen 17 ligeledes blive svinget til åben stilling og omvendt. Tangvægtstængerne 13 og 14's bagud forbi boltene 15 forlængede ender, henholdsvis 13A og 14A, er indbyrdes forbundet ved hjælp af en trækfjeder 20, der i tangvægtstængerne 13 og 14's lukke-20 stilling er spændt. Hver ende 13A og 14A er udformet med en lodret flade 21, som er parallel med boltene 15. Disse flader 21 har i tangvægtstængerne 13 og 14's 1 ukkesti 11 ing, fig. 2, en indbyrdes afstand Z og er indbyrdes parallelle. Mellem fladerne 21 befinder sig i tandvægtstængerne 13 og 14’s lukke-25 stilling en låseblok 22, hvis bredde kun er lidt mindre end afstanden Z. Låseblokken 22 er ved hjælp af en bolt 23 svingeligt forbundet med en på koblingen anbragt håndvægtstang 24, der til muliggørelse af en lodret bevægelse heraf ved sin ene ende ved hjælp af en bolt 25 er svingeligt forbundet med kob-30 lingen, og ved hjælp af en fjeder 26 trykkes til den i fig. 1 viste stilling, i hvilken låseblokken 22 er indskudt mellem de to flader 21. På koblingens bageste ende er anbragt en lodret hydraul- eller pneumatikcylinder eller en elektrisk servomotor 27 under vægtstangen 24.5 The coupling shown has a support plate 11, on the front of which is a catch mouth 12. Two forceps 13 and 14 are pivotal about vertical bolts 15 on the support plate 11. The forceps 14 are formed with a stop 16 for a towbar to be armed. A transverse bar 17 is pivotally connected in a manner known per se 10 to a bolt 18 on the forceps 14 and to a bolt 19 on the forceps 13 so that the movements of the forceps 14 are forcibly transmitted to the forceps 13 and the two forceps simultaneously perform the necessary forceps. and pliers. Thus, if the forceps 14 to 15 are moved open position, the forceps 13 through the transverse bar 17 will also be pivoted to the open position and vice versa. The rear end of the tongs 13 and 14 past the extended ends of the bolts 15, 13A and 14A, respectively, are interconnected by means of a tension spring 20 which is tensioned in the closing 20 position of the tongs 13 and 14. Each end 13A and 14A is formed with a vertical face 21 which is parallel to the bolts 15. These faces 21 have in the tongs 11 and 14 of the tongs 13 and 14 for the week 11, FIG. 2, are spaced apart Z and are parallel to one another. Between the faces 21, in the closing position of the toothed rods 13 and 14, is a locking block 22, the width of which is only slightly smaller than the distance Z. The locking block 22 is pivotally connected to a dumbbell bar 24 arranged on the coupling to enable of a vertical movement thereof at one end by means of a bolt 25 is pivotally connected to the clutch and by means of a spring 26 is pressed to the one shown in FIG. 1 in which the locking block 22 is inserted between the two faces 21. A vertical hydraulic or pneumatic cylinder or an electric servomotor 27 is mounted on the rear end of the coupling under the lever 24.
Når koblingen skal tages i brug, sættes tryk på cylinderen 27, hvorved håndvægtstangen 24 svinges opad og derved trækker lå- 35When the clutch is to be used, pressure is applied to the cylinder 27, whereby the dumbbell bar 24 is pivoted upwards thereby

4 seblokken 22 bort fra fladerne 21. Når denne bevægelse er afsluttet, vil tangvægtstængerne 13 og 14 af fjederen 20 blive trukket til åben stilling, så at de to forreste tangvægtstangsender svinges til siden og anslaget 16 bevæges ind i 5 fangemunden 12. Derpå er koblingen driftsklar. Køres nu koblingen mod en trækhage eller kører en trækhage mod koblingen, vil den til sammenkoblingen bestemte hage indfanges af fangemunden og styres således, at den støder mod anslaget 16, som bevæges bagud indtil trækhagen støder mod fangemunden 12's :o bageste ende. Ved denne forskydning af anslaget 16 svinges tangvægtstangen 14 om bolten 15 til låsestilling, fig. 2, og idet samtidigt gennem tværstangen 17 også tangvægtstangen 13 svinges til låsestilling. Når tangvægtstængerne 13 og 14 har nået den i fig. 2 viste stilling, vil deres flader 21 på bag-15 enderne 13A og 14A have den indbyrdes afstand Z, og låse blokken 22, der har en noget mindre bredde end afstanden Z, vil af fjederen 26 gennem håndvægtstangen 24 blive trykket ind mellem fladerne 21. Nu er koblingsoperationen afsluttet, idet tangvægtstængerne 13 og 14 begge ligger inde i øjet af den 20 trækhage, der er blevet tilkoblet, og de danner således et koblingsøje, der fatholder trækhagen. Heller ikke et træk i trækhagen er i stand til igen at åbne tangvægtstængerne 13 og 14, da dette forhindres af låseblokken 22.4 the seal block 22 away from the faces 21. When this movement is completed, the forceps 13 and 14 of the spring 20 will be pulled to the open position so that the two front forceps ends are pivoted to the side and the stop 16 is moved into the 5 catch 12. serviceable. If the coupling is moved against a towbar or driven by a towbar to the coupling, the hook intended for the coupling will be captured by the catch and guided to abut the stop 16, which is moved backwards until the towbar hits the catch end of the catch 12. In this displacement of the stop 16, the forceps 14 are pivoted about the bolt 15 for locking position. 2, and at the same time through the crossbar 17 the tong bar 13 is also pivoted to the locking position. When the tongs 13 and 14 have reached the position shown in FIG. 2, their faces 21 on the rear ends 13A and 14A will have the spacing Z, and locking the block 22 having a somewhat smaller width than the distance Z will be pushed in by the spring 26 through the dumbbell 24 between the faces 21 Now the coupling operation is completed, the forceps 13 and 14 both being in the eye of the 20 towing hook that has been engaged, thus forming a coupling eye holding the towing hook. Also, a pull in the drawbar is not able to open the tongs 13 and 14 again, as this is prevented by the locking block 22.
25 Til udløsning af koblingen er det derpå kun nødvendigt enten med hånden eller gennem cylinderen eller servomotoren 27 at svinge håndvægtstangen 24 opad, hvorved låseblokken 22 trækkes bort fra mellemrummet mellem fladerne 21, så at fjederen 20 kan trække de to tangvægtstænger 13 og 14 fra hinanden og oo derved frigive den tilkoblede trækhage. Selv om fjederen 20 imidlertid skulle være knækket, vil trækhagen under træk svinge tangvægtstængerne 13 og 14 til åben stilling, idet disse vægtstængers svingakser 15 ligger uden for kraftangrebsretningen. Låseblokken 22 vil i koblingens åbne stilling 35 ligge mod tangvægtstængernes ender 13A og 14A under påvirkning af fjederen 26, Koblingen er nu klar til en ny koblingsoperation.25 To release the clutch, it is then only necessary either by hand or through the cylinder or servomotor 27 to swing the dumbbell 24 upwards, thereby pulling the locking block 22 away from the space between the faces 21, so that the spring 20 can pull the two forceps 13 and 14 apart and oo thereby releasing the coupled tow bar. However, even if the spring 20 is to be broken, the tow bar will in turn swing the forceps 13 and 14 to the open position, the pivot axes 15 of these barbs being outside the direction of force of attack. The locking block 22 will lie in the open position 35 of the clutch against the ends of the tongs 13A and 14A under the influence of the spring 26. The clutch is now ready for a new clutch operation.

Fjederen 20*s fjederkraft kan ganske vist indstilles på i og for sig kendt måde, men under alle omstændigheder vil koblingen blive åbnet, når låseblokken 22 trækkes bort fra fladerne 21. Når dette er tilfældet, vil tangvægtstængerne 13 og 14 un-5 der trækhagens udkørsel blive svinget til åbnesti 11ing og også forblive der, så at koblingen, selv om fjederen 20 skulle være knækket, er koblingsberedt. Låseblokken kan også bære i og for sig kendte midler, hvormed tangvægtstængerne ikke selvhæmmende holdes i åbnestilling f.eks. være udformet med skråflader på 10 låseblokkens underside og tilsvarende skråflader på tangvægtstængerne, således at det forhindres, at tangvægtstængerne i tilfælde af en knækket fjeder 20 under kørsel af sig selv skal gå til låsestilling som følge af køretøjets rystelser.The spring force of the spring 20 * can be adjusted in a manner known per se, but in any case, the clutch will be opened when the locking block 22 is pulled away from the surfaces 21. In this case, the tongs 13 and 14 under the towbar will exit is pivoted to open path 11 and also remains there so that the clutch, although the spring 20 should be broken, is clutch prepared. The locking block may also carry means known per se, by which the tongs are not self-inhibiting in the open position, e.g. be designed with sloping surfaces on the underside of the locking block and corresponding sloping surfaces on the forceps, so that in the event of a broken spring 20, the forceps do not have to go into locking position as a result of the vehicle shaking.
15 Låseblokken 22 kan også skydes ind imellem fladerne 21 i anden retning, f.eks. svinges ind bagfra.The locking block 22 may also be slid in between the faces 21 in another direction, e.g. swung in from behind.
Man kan også gøre den ene af eller begge fladerne 21 let skrå og give låseblokken 22's tilsvarende flader en tilsvarende 20 skråning, så at de også nu er parallelle med fladerne 21. Til forhindring af selvlåsning, der ville forhindre en udtrækning af låseblokken 22, kan man ved hjælp af et anslag for håndvægtstangen 24 eller et anslag for låseblokken sørge for, at denne kun kan skydes så langt ind mellem fladerne 21, at der 25 endnu er et ringe spillerum mellem disse og låseblokken 22's tilsvarende flader, hvorved der ikke kan opstå selvlåsning. Udformes dette anslag eftersti 1leligt, kan man efter slid indstille indføringsgraden for låseblokken 22 således, at tangvægtstængerne 13 og 14 altid er i fuld låsestilling.Alternatively, one or both of the faces 21 may be slightly inclined and the corresponding faces of the locking block 22 inclined to a corresponding slope 20, so that they are also now parallel to the faces 21. To prevent self-locking which would prevent the locking block 22 from being pulled out, by means of a stop for the dumbbell bar 24 or a stop for the locking block, make sure that it can only be pushed so far in between the faces 21 that 25 there is still a little space between them and the corresponding faces of the locking block 22, so that no self-locking. If this stop is designed in a desirable manner, the wear rate of the locking block 22 can be adjusted after wear so that the forceps 13 and 14 are always in full locking position.
30 Sædvanligvis fastholdes trækhagen som følge af fangemundens form således i den dannede koblingstang, at den ikke kan svinge ned og derved bort fra denne.30 Due to the shape of the catch mouth, the drawbar is usually held in the formed coupling rod so that it cannot swing down and thereby away from it.
