Description
Kopling mellom tilhenger og trekkjøretøy. Coupling between trailer and towing vehicle.
Foreliggende oppfinnelse angår en kopling mellom tilhenger og trekkjøretøy for-trinnsvis for anvendelse ved trekkjøretøy med løft- og senkbar trekkramme, hvor tilhengerens trekkstang er koplet svingbart om en vertikal bolt til ett i sideretning bevegelig glidestykke på kjøretøyets trekkramme, samt at trekkstangen noe bakenfor koplingsbolten er forsynt med ett om en vertikal tapp svingbart, tverrsgående styrestag som i sin annen ende er svingbart forbundet med trekkrammen. The present invention relates to a coupling between trailer and towing vehicle, preferably for use with towing vehicles with a lifting and lowering towing frame, where the towbar of the trailer is pivotally connected about a vertical bolt to a laterally movable sliding piece on the vehicle's towing frame, and that the towbar is slightly behind the coupling bolt provided with one or a vertical pivot pivotable transverse guide rod which is pivotably connected to the draw frame at its other end.
Hensikten med oppfinnelsen er å til-veiebringe en kopling av ovenfor nevnte art hvor trekkbolten kan anbringes inn-under trekkjøretøyet for gunstig vektfor-deling av tilhengerbelastningen på trekk - kjøretøyet, altså nærmere dettes bakaksel enn tidligere kjent. The purpose of the invention is to provide a coupling of the above-mentioned kind where the towing bolt can be placed under the towing vehicle for favorable weight distribution of the trailer load on the towing vehicle, i.e. closer to its rear axle than previously known.
Dette oppnås ifølge oppfinnelsen ved at trekkrammen ved hjelp av et hengsel forbundet med en på trekkjøretøyet festet plate som på den ovenfor hengslet beliggende side er forsynt med et låsestykke som når trekkrammen løftes opp, ligger an mot trekkbolten og hindrer at trekkstangen kan hektes av bolten. According to the invention, this is achieved by the towing frame using a hinge connected to a plate attached to the towing vehicle which, on the side located above the hinge, is provided with a locking piece which, when the towing frame is lifted up, rests against the towing bolt and prevents the towing rod from being unhooked from the bolt.
Ifølge et ytterligere trekk ved oppfinnelsen er trekkrammen ved hjelp av et hengsel forbundet med en på trekkjøre-tøyet festet plate som på den ovenfor hengslet beliggende side er forsynt med et låsestykke som når trekkrammen løftes opp, ligger an mot trekkbolten og hindrer at trekkstangen kan hektes av bolten. According to a further feature of the invention, the towing frame is connected by means of a hinge to a plate attached to the towing vehicle which, on the side located above the hinge, is provided with a locking piece which, when the towing frame is lifted, rests against the towing bolt and prevents the towing bar from being hooked of the bolt.
Et utførelseseksempel på oppfinnelsen skal forklares nærmere under henvisning til tegningen. An embodiment of the invention will be explained in more detail with reference to the drawing.
Fig. 1 viser et grunnriss av en kopling Fig. 1 shows a basic diagram of a coupling
ifølge oppfinnelsen med utsvinget feste-plate. Fig. 2 viser et sideriss av fig. 1. Fig. 3 viser et sideriss av koplingen hvor festeplaten er svinget ned over rammen slik at trekkbolten sikres. according to the invention with a flared attachment plate. Fig. 2 shows a side view of fig. 1. Fig. 3 shows a side view of the coupling where the fastening plate is swung down over the frame so that the pull bolt is secured.
Festeplaten 1 er beregnet på å festes tii trekkjøretøyet ved hjelp av de på fig. 1 viste huller. Festeplaten 1 er ved den ene ende ved hjelp av et hengsel 8 forbundet med trekkrammen 3 som har to ører 4 for befestigelse til hydralisk løfte- og senke-innretning. Rammen er forsynt med to tverrgående glidestenger 11 på hvilke et glidestykke 6 er forskyvbart ved hjelp av glidehylser 13. Glidestykket 6 er forsynt med en trekkbolt 7 for tilhengerens trekkstang 9. Noe bakenfor for koplingsbolten 7 er trekkstangen forsynt med ett om en vertikal tapp svingbart, tverrsgående styrestag 5 som i sin annen ende er svingbart forbundet med trekkrammen 3. Den ende av festeplaten 1 som ligger overfor hengslet 8 er forsynt med en låseplate 2 som når trekkrammen 3 er løftet opp ved hjelp av hydraulikken vil ligge over koplingsbolten 7 under dens bevegelse frem og tilbake og hindre at trekkstangen 9 hektes av bolten 7, (se fig. 3). The fastening plate 1 is designed to be attached to the towing vehicle by means of those in fig. 1 showed holes. The fixing plate 1 is connected at one end by means of a hinge 8 to the pull frame 3 which has two lugs 4 for attachment to the hydraulic lifting and lowering device. The frame is provided with two transverse sliding rods 11 on which a sliding piece 6 is displaceable by means of sliding sleeves 13. The sliding piece 6 is provided with a draw bolt 7 for the trailer's draw bar 9. Somewhat behind the coupling bolt 7, the draw bar is provided with one pivotable about a vertical pin, transverse guide rod 5, which at its other end is pivotally connected to the draw frame 3. The end of the fixing plate 1 which lies opposite the hinge 8 is provided with a locking plate 2 which, when the draw frame 3 is lifted up by means of the hydraulics, will lie over the coupling bolt 7 during its movement back and forth and prevent the tie rod 9 from being hooked by the bolt 7, (see fig. 3).
