Description

-1- DK 172648 B1 BESKRIVELSE.-1- DK 172648 B1 DESCRIPTION.

Den foreliggende opfindelse omhandler et sammenkoblings-5 aggregat mellem en traktor og en påhængsvogn med bogie, fortrinsvis en gyllevogn, der er udformet med hver sin trækbom med henholdsvis en trækkrog og et trækeje, og som omfatter en tvangsstyringscylinder.The present invention relates to a coupling assembly between a tractor and a bogie trailer, preferably a slurry carriage, each having a tow bar having a towbar and a tow bar, respectively, comprising a forced steering cylinder.

Ved kendte sammenkoblingsaggregater er der monteret en 10 hydraulikcylinder til traktorens trækbom. Denne cylinder registrerer, hvor meget traktoren drejer sig i forhold til påhængsvognen og bestemmer derved, hvor meget det bagerste hjulpar på påhængsvognens bogie skal dreje.In known coupling assemblies, a 10 hydraulic cylinder is fitted to the tractor drawbar. This cylinder records how much the tractor rotates relative to the trailer and thereby determines how much the rear wheel pair on the trailer's bogie should rotate.

Der er forskellige ulemper ved de kendte sammenkoblings-15 aggregater.There are various disadvantages to the known interconnecting units.

Således er hydraulikcylinderen ved trækbommen meget udsat for sand og vand, hvorfor den slides hurtigt. Sløret mellem traktorens trækkrog og påhængsvognens trækøje medfører utilsigtede drejninger af påhængsvognens drejbare hjul, og da 20 pladsforholdene, hvor hydraulikcylinderen er anbragt, er trange, kan der ikke opnås store udsving i drejebevægeIsen.Thus, the hydraulic cylinder at the tow bar is very exposed to sand and water, which is why it wears off quickly. The blurring between the tractor's towbar and the trailer's towing eye causes unintended turns of the trailer's swivel wheels, and since the 20 space conditions where the hydraulic cylinder is placed are tight, large swings in the pivot movement cannot be achieved.

De kendte sammenkoblingsaggregater er ikke udformet med en vægtoverføring, der kan overføre vægt fra påhængsvognen til traktorens forhjul, hvilket er nødvendigt for at store gylle-25 vogne skal kunne håndteres på en sikker og betjeningsvenlig måde.The known coupling assemblies are not designed with a weight transfer which can transfer weight from the trailer to the front wheel of the tractor, which is necessary for large slurry trucks to be handled in a safe and easy to operate manner.

Endvidere er de tilkoblingsanordninger i form af trækkroge, trækbomme og trækøjer, der indgår i de kendte sammenkoblingsaggregater, ikke i stand til at klare de belastnin-30 ger, som de udsættes for, og slør i tilkoblingsanordnlngerne er årsag til store chockpåvirkninger på såvel traktor som påhængsvogn.Furthermore, the coupling devices in the form of tow hooks, tow barriers and towing eyes included in the known coupling assemblies are unable to cope with the stresses to which they are subjected, and blurs in the coupling devices cause great shock effects on both the tractor and the trailer.

Det er formålet med den foreliggende opfindelse at anvise et sammenkoblingsaggregat af den indledningsvis angivne art, der 35 ikke har ulemperne ved de kendte sammenkoblingsaggregater.It is the object of the present invention to provide an interconnecting assembly of the type initially specified which does not have the disadvantages of the known interconnecting assemblies.

Figure 2 shows, on a larger scale and in perspective, parts of an interconnecting assembly according to the invention, where the drawing bowl is out of engagement with the drawing ball; 3 is a view similar to that of FIG. 2 shows the corresponding picture, in which the drawing bowl is in engagement with the drawing ball, 20 fig. 4 is a schematic, top view, of a tractor, which is clamped on a triple-bogie trailer, by an interlocking device according to the invention, fig. 5 is a schematic top plan view of portions of an interconnecting assembly according to the invention wherein the weight transfer cylinder is inserted into the pivot bracket; and FIG. 6 is a view similar to that of FIG. 5 shows the weight transfer cylinder being pulled out of the swivel bracket.

30 Som vist på fig. 1 er en traktor 1 forspændt for en gyllevogn 2 ved et sammenkoblingsaggregat ifølge opfindelsen.30 As shown in FIG. 1, a tractor 1 is biased for a slurry 2 by a coupling assembly according to the invention.

Sammenkoblingsaggregatet omfatter som vist på fig. 2 og 3 en -4- DK 172648 B1 trækkugle 3, der er monteret på traktoren 1, og en trækskål 4 med en vandret akseltap 5, der er drejeligt monteret i et leje 6 med et beslag 7, der er monteret på gyllevognen 2.As shown in FIG. 2 and 3 a -4- DK 172648 B1 traction ball 3 mounted on the tractor 1 and a traction bowl 4 with a horizontal shaft pin 5 rotatably mounted in a bearing 6 with a bracket 7 mounted on the slurry 2.

5 Sammenkoblingsaggregatet omfatter tillige en drejekonsol 8, der er anbragt i højde med traktorens 1 topstang. Drejekon-sollen kan som vist bestå af en øverste plade 8' og en neder-ste plade 8", der ved beslag holdes i afstand fra hinanden, så der mellem pladerne dannes et hulrum 9.The coupling assembly also comprises a swivel bracket 8 which is positioned at the height of the top bar of the tractor 1. As shown, the swivel bracket may consist of a top plate 8 'and a bottom plate 8 "which are held apart at a distance from each other so that a cavity 9 is formed between the plates.

10 Fortil, ved traktoren, er drejekonsollen 8 svingeligt hængslet ved en lodret akseltap 10 til et beslag 11, der ligeledes kan bestå af en øverste plade 11' og en nederste plade 11", der er anbragt i en indbyrdes afstand, der er lidt mindre end afstanden mellem pladerne 8' og 8" således, at beslaget 11 15 som vist på fig. 2 kan optages i hulrummet 9.10 Furthermore, at the tractor, the swivel bracket 8 is pivotally hinged at a vertical shaft 10 to a bracket 11, which may also consist of a top plate 11 'and a bottom plate 11 "spaced slightly apart. than the distance between the plates 8 'and 8 "so that the bracket 11 15 as shown in FIG. 2 can be accommodated in the cavity 9.

Pladerne 11' og 11" er fastgjort til en vandret akseltap 12, der ved hver ende som vist kan have en neddrejet recess 13.The plates 11 'and 11 "are attached to a horizontal shaft pin 12 which at each end may have a rotated recess 13 shown.

På traktoren 1 er der ud for hver recess monteret et lodret holdebeslag 14, der foroven er udformet med et opadtil åbent 20 U-formet spor 14'.On the tractor 1 a vertical holding bracket 14 is mounted next to each recess, which is formed at the top with an upwardly open 20 U-shaped groove 14 '.

I hulrummet 9 er der som vist på fig. 5 og 6 indbygget et styr 15 for en vægtoverføringscylinder 16 med en stempelstang 17, der ved enden ved en lodret akseltap 18 er svingeligt koblet til påhængsvognen 2. Aksel tappen 18 er anbragt i samme 25 eller tilnærmelsesvis samme niveau som akseltappen (10).In the cavity 9, as shown in FIG. 5 and 6 incorporate a guide 15 for a weight transfer cylinder 16 with a piston rod 17 which is pivotally coupled to the end of a vertical shaft 18 by the trailer 2. The shaft pin 18 is arranged at the same 25 or approximately the same level as the shaft pin (10).

Styret 15 er således udformet, at det kan optage cylinderen 16. Bagtil har styret 15 en åbning 19 således, at cylinderen 16 kan skydes ind i og tages ud af styret, og fortil er styret 15 udformet med en endevæg 20, mod hvilken enden af 30 cylinderen 16 kan komme til anlæg således, at der kan overføres belastninger, der er orienteret fra påhængsvognen 2 i retning mod traktoren 1, fra påhængsvognen over stempelstangen 17 gennem cylinderen 16 til drejekonsollen 8 og derfra til traktoren 1. Da vægtoverføringscylinderen er 35 anbragt i niveau over traktorens baghjulsaksel, vil denne belastning blive overført til traktorens forhjul. For modsat rettede belastninger, hvorved stempelstangen 17 påvirkes til -5- DK 172648 B1 træk, vil cylinderen 16 trækkes delvist eller evt. helt ud af styret 15. Vægtoverføringscylinderen 16 er som vist på fig. 1 forbundet til traktorens hydrauliksystem ved hydrauliske 5 ledninger 21. Herved kan olietrykket og dermed størrelsen af den belastning, der overføres fra påhængsvognen 2 til traktorens 1 forhjul varieres fra førerhuset.The guide 15 is designed so that it can accommodate the cylinder 16. At the rear, the guide 15 has an opening 19 such that the cylinder 16 can be slid into and taken out of the guide, and in the front the guide 15 is formed with an end wall 20, towards which the end of the The cylinder 16 may come into contact so that loads oriented from the trailer 2 in the direction of the tractor 1 can be transferred from the trailer over the piston rod 17 through the cylinder 16 to the rotary bracket 8 and thence to the tractor 1. As the weight transfer cylinder 35 is placed in level above the tractor rear axle, this load will be transferred to the front wheel of the tractor. For opposite loads, whereby the piston rod 17 is actuated to a pull, the cylinder 16 will be partially or possibly pulled. completely out of the guide 15. The weight transfer cylinder 16 is shown in FIG. 1 connected to the hydraulic system of the tractor by hydraulic 5 lines 21. Hereby the oil pressure and thus the amount of load transferred from the trailer 2 to the front wheel of the tractor 1 can be varied from the cab.

Som det fremgår af tegningen er der på hver side af vægtoverføringscylinderen 16 monteret en tvangsstyringscylinder, 10 der består af en hydraulisk cylinder 22 med en stempelstang 23. Cylinderen 22 er ved den frie ende svingeligt hængslet til drejekonsollen 6 ved en lodret akseltap 24, og stempelstangen 23 er ved enden svingeligt hængslet til beslaget 11 ved en lodret akseltap 25. Tvangsstyringscylinderen 26, der 15 er anbragt på den til cylinderen 22 modstående side af vægt-overføringscylinderen 16 kan have samme størrelse som cylinderen 22 og være placeret spejlvendt i forhold til cylinderen 22 om et lodret plan gennem vægtoverføringscylinderen 16.As can be seen from the drawing, on each side of the weight transfer cylinder 16 is mounted a forced steering cylinder 10 consisting of a hydraulic cylinder 22 with a piston rod 23. The cylinder 22 is pivotally hinged to the pivot bracket 6 by a vertical shaft pin 24 and the piston rod. 23 is pivotally hinged at the end to the bracket 11 by a vertical shaft pin 25. The forced guide cylinder 26 disposed on the side opposite the cylinder 22 of the weight transfer cylinder 16 may be of the same size as the cylinder 22 and be positioned flush with the cylinder 22. about a vertical plane through the weight transfer cylinder 16.

Som det især fremgår af fig. 4 er begge cylindre 22 og 26 20 dobbeltvirkende. Cylinderen 22 er ved hydrauliske ledninger 27 koblet til en dobbeltvirkende styrecylinder 28, der er monteret på og koblet til et hjul 29 på påhængsvognens 2 bogie 30.As can be seen in particular from FIG. 4, both cylinders 22 and 26 are double acting. The cylinder 22 is connected by hydraulic lines 27 to a double-acting control cylinder 28 mounted on and coupled to a wheel 29 on the bogie 30 of the trailer 2.

Styrecylinderen 28 har samme størrelse som tvangsstyrlngs-25 cylinderen 22, og de hydrauliske ledninger 27 er koblet således, at de to cylindre 22 og 28 har modsat bevægelsesretning.The control cylinder 28 is the same size as the forced control cylinder 22, and the hydraulic lines 27 are coupled such that the two cylinders 22 and 28 have the opposite direction of movement.

I tilfælde af, at påhængsvognen 2 er udstyret med triple-bogie, er den anden hydrauliske cylinder 26 ved hydrauliske 30 ledninger 31 koblet til en styrecylinder 32, der er monteret på og koblet til et hjul 33 på triplebogiens forreste aksel 34.In case the trailer 2 is equipped with a triple-bogie, the second hydraulic cylinder 26 at hydraulic 30 leads 31 is coupled to a steering cylinder 32 mounted on and coupled to a wheel 33 on the front axle 34 of the triple bogie.

Styrecylinderen 32 har samme størrelse som tvangsstyring-cylindren 26, og de hydaruliske ledninger 31 er koblet såle-35 des, at de to cylindre 26 og 32 har modsat bevægelsesretning.The control cylinder 32 is the same size as the forced control cylinder 26, and the hydraulic lines 31 are coupled so that the two cylinders 26 and 32 have the opposite direction of movement.

For ikke at overbelaste de hydrauliske systemer, er der som DK 172648 B1 -fe- vist på tegningen monteret trykekspansionsbeholdere 35 i de hydrauliske ledninger 27 og 31.In order not to overload the hydraulic systems, pressure expansion vessels 35 are mounted in the hydraulic lines 27 and 31 as shown in the drawing.

Som vist på fig. 3 kan der på traktoren vsre monteret beslag 5 36, på hvilke der aftageligt kan monteres en spærreaksel 37, der ligger an mod oversiden af trækskålen 4, når denne er nedsænket over og er indgreb med trækkuglen 3.As shown in FIG. 3, bracket 5 36 can be mounted on the tractor, on which can be removably mounted a locking shaft 37 which abuts the upper side of the draw bowl 4 when it is submerged and engages the tow ball 3.
