ON [X2 (Tv PJ 2 Tryckelementets tryck kan med fördel vara inställbart och det kan vara företrädesvis elektroniskt reglerbart i beroende av dragfordonets färdhastighet/eller släplastens totalvikt.ON [X2 (Tv PJ 2 The pressure of the pressure element can advantageously be adjustable and it can preferably be electronically adjustable depending on the travel speed of the towing vehicle and / or the total weight of the trailer.
Tryckelementet kan besta av en cylinder-kolv-enhet med tallriks- fjädrar anordnade mellan kolven och cylindern, och cylindern, med inställbar totallängd, kan vara ledat fäst vid det svängbara bär-elementet medan kolven, under mellankoppling av ett ledat vid denna infäst stangorgan, med en axel ingriper i en raklinjig kuliss med tva förskjutna ändlägen för axeln.The pressure element may consist of a cylinder-piston unit with disc springs arranged between the piston and the cylinder, and the cylinder, with adjustable overall length, may be hingedly attached to the pivotable support member while the piston, during interconnection of an articulated rod member, with one shaft engages in a straight line with two offset end positions for the shaft.
Axeln kan vara förskjutbar i kulissen medelst ett handtag.vilken a ena sidan är längsförskjutbar i ett vid axeln angripande ledorgan och a andra sidan med detta ledorgan kan svängas fran ett läge i rät vinkel med axeln.The shaft can be displaceable in the setting by means of a handle, which on the one hand is displaceable longitudinally in a hinge member attacking the shaft and on the other hand with this hinge member can be pivoted from a position at right angles to the shaft.
Vidare kan anordningen med fördel vara utformad pa sa sätt att stangorganets ledpunkt vid kolven i cylinder-kolv-enheten i tryckelementets driftslåge ligger i överdödpunktsläget utanför förbindningslinjen mellan cylinderns ledpunkt vid det svänghara bärelementet och stangorganets led- punkt vid axeln.Furthermore, the device can advantageously be designed in such a way that the joint point of the rod member at the piston in the cylinder-piston unit in the operating position of the pressure element is in the dead center position outside the connecting line between the cylinder joint point at the pivot bearing member and the rod member joint point at the shaft.
Ett anslag kan vara anordnat vid cylinder-kolv-enhetens kolv vid vilken en pa axeln befintlig rulle anligger i cylinder-kolv-enhetens överdöd- punktsläge.A stop may be provided at the piston of the cylinder-piston unit in which a roller present on the shaft abuts in the dead center position of the cylinder-piston unit.
För att kunna utjämna tillverkningstoleranser och eventuellt slitage hos bromsklossarna, kan ledpunkten för cylinder-kolv-enhetens cylinder vara försedd med en justerbar excenter vid det svängbara bärelementet .In order to be able to equalize manufacturing tolerances and possible wear of the brake pads, the articulation point for the cylinder of the cylinder-piston unit can be provided with an adjustable eccentric at the pivotable support element.
I ritningen visas ett utföringsexempel enligt uppfinningen.The drawing shows an embodiment according to the invention.
Här visar: figur l: i sidovy en kulledskoppling med bromsskiva och en icke tillkopplad dragstang hos en släpvagn med de delar som samverkar med bromsskivan, . figur 2: föremalet enligt figur 1 med dragstang kopplad vid kulledskopplingen och figur 3: en planvy av illustrationen enligt figur 2.Here shows: figure 1: in side view a ball joint coupling with brake disc and an uncoupled drawbar of a trailer with the parts that interact with the brake disc,. figure 2: the object according to figure 1 with a drawbar connected to the ball joint coupling and figure 3: a plan view of the illustration according to figure 2.
I enlighet med figur l är en bromsskiva 3 medelst skruvorgan 4 fäst vid kulhalsen 2 som bär kopplingskulan 1 i en kulledskoppling som är anordnad vid ett motorfordons bakdel, pa sa sätt att bromsskivan sträcker sig bakat i horisontell riktning. Kulhalsen 2 skjuter härvid med kopplingskulan 1 genom en borrning i bromsskivan 3 vilken väsentligen är cirkelformigt utformad, och sasom närmare framgar i figur 3 sträcker sig över en omkrets 462 526 3 pa cirka 2800. Pa båda sidor om infästningsstället vid kulhalsen 2 är urtag- ningar 5 anordnade pa bromsskivan 3 vilka ligger pa en cirkelbage och vilka sträcker sig ungefär till en linje 6 som gar genom bromsskivans centrum och som ligger tvärs kulhalsen.In accordance with Figure 1, a brake disc 3 is attached by means of screw means 4 to the ball neck 2 which carries the clutch ball 1 in a ball joint coupling which is arranged at the rear of a motor vehicle, in such a way that the brake disc extends backwards in horizontal direction. The ball neck 2 then projects with the coupling ball 1 through a bore in the brake disc 3 which is substantially circular, and as can be seen in more detail in Figure 3 extends over a circumference 462 526 3 pa of approximately 2800. On both sides of the attachment point at the ball neck 2 there are recesses 5 arranged on the brake disc 3 which lie on a circular bag and which extend approximately to a line 6 which passes through the center of the brake disc and which lies across the ball neck.
Ett bärelement 8 är fäst vid en släpvagns dragstang, vilket är försedd med en nedat riktad bromskloss 9 och vid bärelementet 8 är ett bärelement 10 anordnat vilket är svängbart runt axeln 10a pa bärelementet 8 och uppvisar en uppat riktad bromskloss ll. Det svängbara bärelementet 10 hänger nedat. Vid dettas fria ände är, vid ledpunkten 12, cylindern 13 hos ett som ett cylinder-kolv-enhet utformat tryckelement 14 ansluten, vars kolv 15 under mellankoppling av ett ledat anslutet stangorgan 16 är fast förbundet med en axel 17 vilken medelst ett handtag 21 är förskjutbar i en vid bärelementet 8 anordnad, väsentligen horisontellt liggande kuliss med tva nedat förskjutna ändlägen 19, 20 för axeln 17. l-Iandtaget 21 är förskjutbart i sin längdriktning i ett vid axeln 17 fäst ledorgan 22 (fig 3), och kan dessutom med detta ledorgan svängas ur ett läge i rät vinkel med axeln 17.A support element 8 is attached to a drawbar of a trailer, which is provided with a downwardly directed brake pad 9 and at the support element 8 a support element 10 is arranged which is pivotable about the axis 10a of the support element 8 and has an upwardly directed brake pad 11. The pivotable support element 10 hangs downwards. At its free end, at the articulation point 12, the cylinder 13 of a pressure element 14 designed as a cylinder-piston unit is connected, the piston 15 of which, during interconnection of an articulated connected rod member 16, is fixedly connected to a shaft 17 which by a handle 21 is displaceable in a, substantially horizontally lying scenery arranged at the support element 8 with two downwardly displaced end positions 19, 20 for the shaft 17. The handle 21 is displaceable in its longitudinal direction in a hinge member 22 (Fig. 3) attached to the shaft 17, and can also this hinge member is pivoted from a position at right angles to the shaft 17.
Tallriksfjädrar är anordnade i tryckelementet 14 mellan kolven 15 och cylindern 13. Cylinderns 13 verksamma längd kan ändras.Till detta syfte är den del av cylindern som angriper vid ledpunkten 12 inställbar i förhållande till den övriga cylinderdelen med hjälp av en gänga. Ledpunkten 12 är försedd med en inställbar excenter.Disc springs are arranged in the pressure element 14 between the piston 15 and the cylinder 13. The effective length of the cylinder 13 can be changed. For this purpose, the part of the cylinder which engages at the articulation point 12 is adjustable relative to the rest of the cylinder part by means of a thread. The leading point 12 is provided with an adjustable eccentric.
Om dragstangen ej är tillkopplad intar alla delarna läget som ses i figur 1. Axeln 17 vilar i kulissens 18 ändläge 20.If the drawbar is not connected, all the parts assume the position shown in figure 1. The shaft 17 rests in the end position 20 of the stage 18.
Om släpvagnen är kopplat till dragfordonet, som visas i figur 2, och den vid dragstangen 7 anordnade kopplingsskalen 23 är last pa kopp- lingskulan 1, ligger bromsskívans 3 yttre omraden under bromsklossen 9 pa bärelementet 8. Efter det att cylinderns 13 verksamma längd för gällande släplast ställts in vid cylindern 13 i tryckelementet 14 under användning av markeringarna 24 för varierande släplaster, lyftes axeln 17 med hjälp av handtaget 21 ur ändläget 20 och föres längs kulissen 18 och insättes i ändläget 19 sa att det med axeln 17 förbundna tryckelementet 14 rör det svängbara bärelementet 10 med bromsklossen ll till anliggning mot broms- skivan 3 mitt emot bromsklossen 9. Därpa vrides stangorganet 16 sa langt med handtaget 21 att stangorganets 16 ledpunkt vid kolven 15 star i överdödpunktsläge. Detta läge säkras medelst ett anslag 24 vid kolven 15 vilket gar mot en rulle 25 som finns pa axeln 17. 462 526 4 Balkarna 8 och lU bildar tillsammans en bromstang som manöv- reras med handtaget 21. Vid öppnad bromstàng lägger sig bromsskívan 3 av sig själv under bromsklossen 9 vid tillkopplande av dragstangen 7. Vid sluten bromstang utövar bromsklossarna 9, 10 en sådan friktionskraft på broms- skivan 3 att svängningsrörelser hos släpvagnen säkert kan fångas upp. Med hjälp av bromsskívan 3 uppnås vidare att de vertikala stödkrafterna pa kopplingskulan l delas upp pa axlarna hos dragfordon och släpvagn. Ett "knäckläge" vid kopplingspunkten bortfaller. De extremställningar av släp- vagnens dragstang i förhållande till dragfordonet som är möjliga vid tillkoppling utan att bromsskívan utgör ett hinder, kan ses i figur 3Ii vilket ett extremlâge hos dragstangen anges med streckad linje.If the trailer is coupled to the towing vehicle, shown in figure 2, and the coupling shell 23 arranged at the drawbar 7 is loaded on the coupling ball 1, the outer region of the brake disc 3 lies below the brake pad 9 on the support element 8. After the effective length of the cylinder 13 trailer load set at the cylinder 13 in the pressure element 14 using the markings 24 for varying trailer loads, the shaft 17 is lifted by means of the handle 21 from the end position 20 and moved along the link 18 and inserted in the end position 19 so that the pressure element 14 connected to the shaft 17 touches the pivotable support element 10 with the brake pad 11 to abut against the brake disc 3 opposite the brake pad 9. Then the rod member 16 is rotated so far with the handle 21 that the link member 16 of the rod member at the piston 15 is in the dead center position. This position is secured by means of a stop 24 at the piston 15 which bears against a roller 25 which is located on the shaft 17. 462 526 4 The beams 8 and 11 together form a brake rod which is maneuvered with the handle 21. When the brake rod is opened, the brake disc 3 settles itself under the brake pad 9 when coupling the drawbar 7. When the brake lever is closed, the brake pads 9, 10 exert such a frictional force on the brake disc 3 that pivoting movements of the trailer can be safely captured. By means of the brake disc 3 it is further achieved that the vertical support forces on the clutch ball 1 are divided on the axles of the towing vehicle and trailer. A "buckling position" at the connection point is eliminated. The extreme positions of the trailer's drawbar in relation to the towing vehicle which are possible when coupling without the brake disc constituting an obstacle can be seen in Figure 3Ii, which an extreme position of the drawbar is indicated by a dashed line.
