Description
8102392-1 Genom att den hydrauliska regellåsanordningen anordnas som en mellandel mellan förarhyttens bärlagerområde och själva stöt- dämpar- och/eller fjäderanordningen,påverkas inte fjädrings- egenskaperna när denna mellandel byggs in, eftersom förarhyt- ten permanent vilar på sin stötdämpar- och/eller fjäderan- ordning. Om denna anordning avlastas, exempelvis 9en0m inbr0mS- ning och ett därigenom hos förarhytten uppkommet framåt riktat vridmoment,så förhindrar vid slutet av fjädringsbanan förar- hyttens genom regelorganet låsta mottagningsdel att förarhyt- ten i förtid börjar att stjälpas. Tvärtom, förarhytten förbin- des med kraftingrepp via båda stötdämpar- och/eller fjäder- anordningar med fordonets ram så att, i motsats till teknikens ståndpunkt, kraftöverföringen till ramen inte äger rum vid en anordning, utan vid de båda anordningarna, totalt på två stäl- len. Dessutom kan stjälpbara förarhytter hos lastbilar även i efterhand utan större omkostnader utrustas med den som en sär- skild mellandel utformade regellâsanordningen. I vart fall på- verkas fordonets fjädringsegenskaper inte genom regellåsanord- ningen enligt uppfinningen, varvid högsta säkerhet med avseen- de på oläglig stjälpning bibehålles. By arranging the hydraulic control locking device as an intermediate part between the cab bearing bearing area and the shock absorber and / or the spring device itself, the suspension properties are not affected when this intermediate part is built in, since the driver's cab rests permanently on its shock absorber and / or spring device. If this device is relieved, for example by braking and a forward torque thereby generated by the cab, the receiving part of the cab locked by the control means at the end of the suspension path prevents the cab from starting to overturn prematurely. On the contrary, the cab is connected by force engagement via both shock absorbers and / or spring devices to the vehicle frame so that, contrary to the state of the art, the power transmission to the frame does not take place at one device, but at the two devices, in two positions. - len. In addition, rollover cabs for lorries can also be equipped afterwards with the overhead locking device designed as a special intermediate part without major overheads. In any case, the suspension properties of the vehicle are not affected by the locking device according to the invention, whereby the highest safety with regard to inconvenient overturning is maintained.
Lämpliga utföringsformer och vidare utvecklingar av uppfin- ningen anförs i underkraven samt framgår av följande beskriv- ning av en som exempel angiven föredragen utföringsform i en- lighet med närsluten ritning vilken visar ett schematisk tvär- snitt genom en stötdämpar- och/eller fjäderanordning med en regellåsanordning enligt uppfinningen.Suitable embodiments and further developments of the invention are stated in the subclaims and appear from the following description of an exemplary preferred embodiment in accordance with the close-up drawing which shows a schematic cross-section through a shock absorber and / or spring device with a locking device according to the invention.
Anordningen 1 innefattar en stötdämpare 2 som vid sin nedre ände 3 via gummifjädrar 4 är fäst vid ramen 5 av en icke visad lastbil. Vid stötdämparens 2 rörliga kolv 6 är mxælmzett därpå anordnat bärlager 7 en skruvlinjeformig fjäder 8 anordnad kon- centriskt till stötdämparen 2. Såväl fjädern 8, som stötdämpa- ren 2 är fästa vid den ena sidan av en som en mellandel ut- formad regellâsanordning 9. ._..._.._._. .à_.. . ._ _ . r-v-f-f» 8102392-1 Regellåsanordningen 9 är fäst vid undersidan 10 av en icke visad förarhytt, i dennas bärlagerområde. Vid förar- hyttens undersida 10 är anordnad en mottagardel 11 i form av en bult med en ansats 12 vid sin fria ände.The device 1 comprises a shock absorber 2 which at its lower end 3 is attached via rubber springs 4 to the frame 5 of a truck (not shown). At the movable piston 6 of the shock absorber 2, a bearing bearing 7 arranged thereon is a helical spring 8 arranged concentrically to the shock absorber 2. Both the spring 8 and the shock absorber 2 are attached to one side of a control locking device 9 designed as an intermediate part. ._..._.._._. .à_ ... ._ _. r-v-f-f »8102392-1 The locking device 9 is attached to the underside 10 of a driver's cab (not shown), in its load-bearing area. At the underside 10 of the cab is arranged a receiving part 11 in the form of a bolt with a shoulder 12 at its free end.
Den som en mellandel'utformade regellåsanordningen uppvisar ett regelorgan 13, närmare bestämt en hydraulcylinder 14 som förflyttar en tapp 13 vilken tätas av en omslutande tätning 15. Vidare finns vid undersidan av den kolv 1Q som kan för- flyttas i hydraulcylindern 14, en tillslutningsfjäder 151 vilken förflyttar taPPen l3 till dess låsläge. Kolven 16 är utfor- mad som en styrslid med två bakom varandra liggande, icke vi- sade styröppningar av vilka den ena är via en backslagsventil och den andra direkt förbunden med matarledningen. Den and- ra styröppningen friges först när läsningen genom tappen 13 frigörs.The control locking device designed as an intermediate part has a control means 13, more particularly a hydraulic cylinder 14 which moves a pin 13 which is sealed by an enclosing seal 15. Furthermore, at the underside of the piston 10 which can be moved in the hydraulic cylinder 14, there is a closing spring 151 which moves the tap 13 to its locked position. The piston 16 is designed as a guide slide with two guide openings lying one behind the other, not shown, one of which is via a non-return valve and the other directly connected to the supply line. The second guide opening is only released when the reading through the pin 13 is released.
Vid mellandelens ena sida 17, undersidan, är en gängad urborr- ning 18 för mottagning av en gängad och medelst en låsmutter 20 säkrad bult 19 av stötdämparen 2 anordnad. En cirkelring- formig stödyta 21 förefinnes för skruvlinjefjädern 8.At one side 17, the underside of the intermediate part, a threaded bore 18 for receiving a threaded bolt 19 of the shock absorber 2 secured by means of a lock nut 20 is arranged. A circular annular support surface 21 is provided for the helical spring 8.
Vid den sida av mellandelen 9 som ligger mittemot undersidan 17 är en företrädesvis som urborrning utformad öppning 22 med en försänkning 23 anordnad. Försänkningen 23 tjänstgör som styrorgan för upptagningsdelens vulst 12. I det i ritning- en visade fastreglade läget ingriper tappen 13 i urborrning- ens 22 fria utrymme bakom mottagardelens vulst 12, så att den- na del - och därigenom även förarhytten 10 - är med kraftin- grepp förbunden med mellandelen 9 och därigenom via anordningen 1 är med kraftingrepp förbunden med fordonets ram 5. Lämpligen anordnas koncentriskt med urborrningen 22 resp. försänkningen 23 ett cirkelringformigt bärlager 24 för förarhyttens 10 un- dersida. Bärlagret kan företrädesvis bestå av en ring av elas- tiskt eller eftergivligt material såsom gummi.At the side of the intermediate part 9 which lies opposite the underside 17, an opening 22 preferably formed as a bore with a recess 23 is arranged. The recess 23 serves as a guide means for the bead 12 of the receiving part. In the fixed position shown in the drawing, the pin 13 engages in the free space of the bore 22 behind the bead 12 of the receiving part, so that this part - and thereby also the cab 10 - is with the force - grips connected to the intermediate part 9 and thereby via the device 1 are by force engagement connected to the frame 5 of the vehicle. Suitably arranged concentrically with the bore 22 resp. the recess 23 is an annular support bearing 24 for the underside of the cab 10. The carrier layer may preferably consist of a ring of elastic or resilient material such as rubber.
