Description

464 695 härvid kan öppnandet av denna regleras med en och samma tryckcylinder. Eftersom bilarna är färdigt försedda med ett pneumatiskt sk. lâgtrycks- och högtrycksområde, går pneumatiska uttagningar enkelt att säkra så att det inte ens av misstag kan komma tryck i släpvagnskopplingen och dess styranordningar då fordonskombinationens hastighet överstiger ca 30 km/h. 464 695 in this case, the opening of this can be regulated by one and the same pressure cylinder. Because the cars are fully equipped a pneumatic so-called. low pressure and high pressure range, possible pneumatic recesses easy to secure so that it does not even by mistake there may be pressure in the trailer coupling and its control devices then the speed of the vehicle combination exceeds about 30 km / h.

Uppfinningen skall i det följande beskrivas när- i mare under hänvisning till närslutna ritningar, där figur 1 visar en släpvagnskoppling sedd snett uppifrån, figur 2 visar en tryckcylinder i snitt, figur 3 visar släpvagnskopplingen i snitt, figur 4 visar en säkringslåstapp i snitt.The invention will be described in the following when in mare with reference to close-up drawings, there figure 1 shows a trailer coupling seen obliquely from above, figure 2 shows a printing cylinder in section, figure 3 shows the trailer coupling in section, figure 4 shows a safety locking pin in section.

En släpvagnskoppling består av en stomdel 1 och en i stomdelen i vertikalriktning förskjutbar kopplings- bult 2, som i låst läge låser öglan i släpvagnens drag- stång vid stomdelen och i öppet läge lösgör öglan från stomdelen. Kopplingsbulten kan med hjälp av en tryckcy- linder 3 förskjutas mellan låst och öppet läge. Tryckcy- linderns 3 kolvstång 4 uppvisar en kuggning, i samband med vilken ett kugghjul 5 är anordnat och som enligt pi- len öïförmedlarnen.vridrörelse till en axel 7 som lyfter kopplingsbulten 2. Nämnda vridrörelse har man tidigare åstadkommit genom att vrida en spak B för hand. Tryckcy- lindern 3 är vridbart fäst vid axeln 7 så, att den av kopplingsbultens lyftrörelse orsakade vridkraften (pil 9) får tryckcylindern att tryckas mot en i släpvagns- kopplingen belägen säkringslåstapp 10 och förskjuta den- na tapp först i öppet läge såsom visats i figur 4 me- delst pilar. öppnandet av säkringslâstappen kan åstad- kommas genom många olika enkla lösningar.A trailer coupling consists of a body part 1 and a vertically displaceable coupling member in the body part bolt 2, which in the locked position locks the loop in the towbar of the trailer rod at the body part and in the open position releases the loop from body parts. The coupling bolt can be linder 3 is moved between locked and open position. Pressure cycle linder 3 piston rod 4 has a tooth, in connection with which a gear 5 is arranged and which according to len öïförmedlarnen.vistor movement to a shaft 7 that lifts coupling bolt 2. The said rotary movement is previously present achieved by turning a lever B by hand. Pressure cycle the relief 3 is rotatably attached to the shaft 7 so that it is off the lifting movement of the coupling bolt caused the torque (arrow 9) causes the pressure cylinder to be pressed against one of the coupling located safety locking pin 10 and shift the drop first in the open position as shown in Figure 4 part arrows. the opening of the safety locking pin can come through many different simple solutions.
