Ritning.Drawing.
Ett utföringsexempel av uppfinningen visas på åtföljande rit- ning och beskrives nedan närmare. Pig. 1 visar arrangemanget av styrventilen mellan ett underrede och en påbyggnad, fig. 2 visar styrventilen med en manöverarm av fjädrande material och fig. 3 visar styrventilen sedd uppifrån.An embodiment of the invention is shown in the accompanying drawing and is described in more detail below. Pig. Fig. 1 shows the arrangement of the control valve between a chassis and a superstructure, Fig. 2 shows the control valve with a control arm of resilient material and Fig. 3 shows the control valve seen from above.
Beskrivning av utföringsexemplen.Description of the embodiments.
En styrventil 1 för en luftfjädríngsanläggning är mellan ett underrede 2 och en fordonspåbyggnad 3. 3 är en förarhytt. Denna har en tippaxel 4, kring förarhytten är tippbar, samt en spârranordning 5. visas två stötdämpare 6 och 7. vilka är anordnade fordonsaxel 8 och fordonets påbyggnad 3. anordnad Påbyggnaden vilken Dessutom mellan en Styrventilen 1 är vid utföringsexemplet fäst på fordonsaxeln 8. närmare bestämt på en axelhållare 8' och har en manöverarm 9. vars fria ände är ledat förbunden med fordonspåbyggnaden 3.A control valve 1 for an air suspension system is between a chassis 2 and a vehicle body 3. 3 is a driver's cab. This has a tilting shaft 4, around the driver's cab is tiltable, and a locking device 5. two shock absorbers 6 and 7 are shown which are arranged vehicle axle 8 and the vehicle body 3. arranged The body which in addition between a control valve 1 is attached to the vehicle shaft 8 in more detail. fixed on a shaft holder 8 'and has an operating arm 9. whose free end is articulated connected to the vehicle body 3.
Denna anordning kan emellertid även vara omvänt anordnad, var- vid då styrventilen 1 år fäst på fordonspåbyggnaden 3 och den fria armânden är ledat förbunden med fordonsaxeln 8.However, this device can also be arranged in reverse, whereby when the control valve 1 is attached to the vehicle body 3 and the free arm end is articulated connected to the vehicle axle 8.
Pig. 2 visar styrventilen 1 i snitt. Som framgår är den ut- formad som dubbelsätesventil 10 och har ett inre ventilsäte 11. som är anordnat vid änden av en plasthylsa 12. Nära sin andra ände en hake 15 13 har plasthylsan 12 en radiell slits 14. i vilken griper in. som är utformad på manöverarmen 9.Pig. 2 shows the control valve 1 in section. As can be seen, it is designed as a double-seat valve 10 and has an inner valve seat 11. which is arranged at the end of a plastic sleeve 12. Near its other end a hook 13 has the plastic sleeve 12 a radial slot 14. in which it engages. which is formed on the control arm 9.
Armen 9 är böjd av en stång av fjädrande rundmaterial. Kort framför naken lS är armen 9 böjd till en lindning 16. vilken _ såsom bäst framgår av fig. 3 - omfattar 1,75 varv. lindning 16 är armen 9 vridbart påsatt på en hylsa 17. som med en därpå utformad tapp 18 är fast förankrad vid en konsol 19 hos ett ventilhus 20. En vridníngspunkt p för armen 9 bildas Med denna 459 244 av líndníngens 16 mittpunkt. En bälg 21 omger denna lagring av armen 9 och häller den fri från damm och smuts.The arm 9 is bent by a rod of resilient round material. Shortly in front of the naked 1S, the arm 9 is bent into a winding 16. which - as best seen in Fig. 3 - comprises 1.75 turns. winding 16, the arm 9 is rotatably mounted on a sleeve 17. which with a pin 18 formed thereon is fixedly anchored to a bracket 19 of a valve housing 20. A pivot point p for the arm 9 is formed with this 459 244 of the center of the winding 16. A bellows 21 surrounds this bearing of the arm 9 and pours it free from dust and dirt.
Det är även möjligt och ligger klart inom uppfinníngens ram att förse styrventilen med en slidventil istället för en dub- belsätesventíl.It is also possible and clearly within the scope of the invention to provide the control valve with a slide valve instead of a double-seat valve.
