Abstract

The vehicle cab tipping cylinder (2) has one end (6) of the tipping cylinder housing (8) pivotable and from which the tipping cylinder piston rod (10) emerges. The tipping cylinder housing end is fixed to a relatively fixed part in the vehicle (14). The cab tipping cylinder lever arm (B) relative to the vehicle cab tipping point (20) is maintained relatively constant during the whole tipping process.

Föreliggande uppfinning avser en hyttippcylinder 2 för en fordonshytt 4, där den ände 6 av hyttippcylindems 2 cylinderhus 8 från vilken kolvstången 10 utträder är svängbart fäst vid en relativt fast del 12 hos fordonet 14.The present invention relates to a cab tipping cylinder 2 for a vehicle cab 4, where the end 6 of the cab housing 8 of the cab tipping cylinder 2 from which the piston rod 10 emerges is pivotally attached to a relatively fixed part 12 of the vehicle 14.

Figur l visar schematiskt en främre del av ett fordon 14 i fordonshyttens 4 nedfällda läge. En hyttippcylinder 2 är anordnad på åtminstone en sida av fordonet 14 och fast vid en relativt fast del 12 hos fordonet 14, där den relativt fasta delen 12 exempelvis kan vara en hjulupphäng- ning (ej visat) hos fordonet men företrädesvis är fordonets 14 ram 16. Hyttippcylindern 2 är företrädesvis anordnad fórom fordonets 14 främre hjul 18. Hyttippcylindern 2 innefattar ett cylinderhus 8 och en kolvstång 10. Hyttippcylinderns 2 cylinderhus 8 är svängbait fäst med den ände 6 från vilken kolvstången 10 utträder vid den relativt fasta delen 12 hos fordonet 14.Figure 1 schematically shows a front part of a vehicle 14 in the lowered position of the vehicle cab 4. A cab tipping cylinder 2 is arranged on at least one side of the vehicle 14 and fixed to a relatively fixed part 12 of the vehicle 14, where the relatively fixed part 12 may for instance be a wheel suspension (not shown) of the vehicle but preferably the frame 14 of the vehicle 14 The cab tipping cylinder 2 is preferably arranged in front of the front wheels 18 of the vehicle 14. The cab tipping cylinder 2 comprises a cylinder housing 8 and a piston rod 10. The cylinder housing 8 of the cab tipping cylinder 2 is pivotally attached to the end 6 from which the piston rod 10 exits the relatively fixed part 12 of the vehicle 14.

Kolvstången 10 är fäst vid fordonets 14 hytt 4 med den ände 19 som är anordnad på utsidan av cylinderhuset 8. Fordonets 14 hytt 4 uppvisar vidare en tippunkt 20 kring vilken fordo- nets14 hytt 4 är svängbart fäst.The piston rod 10 is attached to the cab 4 of the vehicle 14 with the end 19 arranged on the outside of the cylinder housing 8. The cab 4 of the vehicle 14 further has a tipping point 20 around which the cab 4 of the vehicle 14 is pivotally attached.

Figur 2 visar schematiskt en främre del av ett fordon 14 i fordonshyttens 4 uppfállda läge.Figure 2 schematically shows a front part of a vehicle 14 in the raised position of the vehicle cab 4.

Hytten 4 är tippad så långt kring hyttens 4 tippunkt 20 så att hyttens 14 tyngdpunkt 22 befin- ner sig forom hyttens 4 tippunkt 20, vilket exempelvis betyder i storleksordningen 60 graders öppningsvinkel mellan hyttens uppfallda och nedfallda läge, for att hytten 4 ej skall kunna falla ner av sig sj älv. Som ytterligare säkerhet används ett stag 24 mellan hytten 4 och fordo- arna; 10 'S25 103 . . ~ ; t: nets 14 ram 16 vilket låser hytten 4 i dess uppfällda läge. Så som kan ses ur figuren har hytt- tippcylindem 2 svängt kring sin fästpunkt 26 vid fordonets 14 ram 16 varvid den andra änden 28 av hyttippcylindem 2, i figuren den nedre änden, utför en svängningsrörelse A riktad mot fordonets 14 främre hjul 18. För att cylinderhuset 8 skall kunna svänga fritt är fordonets 14 styrapparat (ej visad) anordnad på den andra sidan fordonet 14.The cab 4 is tilted so far around the tip 4 of the cab 4 that the center of gravity 22 of the cab 14 is located in front of the tip 20 of the cab 4, which means, for example, in the order of 60 degrees opening angle between the cab's up and down position, so that cab 4 cannot fall down by itself. As additional security, a stay 24 is used between the cab 4 and the vehicles; 10 'S25 103. . ~; t: nets 14 frame 16 which locks the cab 4 in its raised position. As can be seen from the figure, the cab tipping cylinder 2 has pivoted about its attachment point 26 at the frame 16 of the vehicle 14, the other end 28 of the cab tipping cylinder 2, in the figure the lower end, performing a pivoting movement A directed towards the front wheels 18 of the vehicle 14. the cylinder housing 8 must be able to turn freely, the control device of the vehicle 14 (not shown) is arranged on the other side of the vehicle 14.

Eftersom hyttippcylindern 2 svänger kring den ände 6 från vilken kolvstången 10 utträder kommer hyttippcylindems 2 hävarm B relativt hyttens 4 tippunkt 20 att hålla sig relativt kon- stant under hela tippforloppet, varvid kraftema mellan hyttippcylindern 2 och hytten 4 håller sig relativt konstanta. Eftersom hävarrnen B ej förkortas på samma sätt som vid den tidigare kända tippcylindem blir krafterna lägre varvid en cylinder med klenare dimensioner kan an- vändas.Since the cab tipping cylinder 2 pivots about the end 6 from which the piston rod 10 exits, the lever B of the cab tipping cylinder 2 relative to the tipping point 20 of the cab 4 will remain relatively constant throughout the tipping process, the forces between the cab tipping cylinder 2 and the cab 4 remaining relatively constant. Since the lever B is not shortened in the same way as with the previously known tipping cylinder, the forces become lower, whereby a cylinder with smaller dimensions can be used.
