Description
2 8200505-9 Uppfinningëíïkommer i det följande att närmare beskrivas i anslutning till bifogade *ritningar där fig 1 visar ett längdsnitt av en vägvält i schematiskt utförande för- sedd med en midjeled i enlighet med uppfinningen, fig 2 visar ett horisontalsnitt genom välten med vältvalsarna orienterade mitt bakom varandra samt fig 3 slutligen ett horisontalsnitt med valsarna sidoförskjutna i förhållande till varandra. The invention will now be described in more detail in connection with the accompanying drawings, in which Fig. 1 shows a longitudinal section of a road roller in schematic embodiment provided with a waist joint in accordance with the invention, Fig. 2 shows a horizontal section through the roller with the roller rollers oriented in the middle behind each other and Fig. 3 finally a horizontal section with the rollers laterally offset in relation to each other.
Med 1 och 2 betecknas vältens främre respektive bakre vals. De är lagrade i var sin vältram 3 respektive 4, vilka är förbundna med varandra genom en midjeled 5,vilken medger kurvtagning och sidoförskjutning av valsarna i förhållande till varandra.1 and 2 denote the front and rear rollers of the roller, respectively. They are mounted in respective roller frames 3 and 4, respectively, which are connected to each other by a waist joint 5, which allows cornering and lateral displacement of the rollers relative to each other.
Midjeleden 5 består av ett mellanstycke 6, vilket i sin ena ände är svängbart lagrat på en tapp 7 i den främre vältramen 3 och på en tapp 8 i den bakre vältramen 4. Mellan- stycket 6 uppvisar en i sidled utskjutande och med mellanstycket fast förenad arm 9.The waist joint 5 consists of an intermediate piece 6, which at its one end is pivotally mounted on a pin 7 in the front roller frame 3 and on a pin 8 in the rear roller frame 4. The intermediate piece 6 has a laterally projecting and fixedly connected to the intermediate piece arm 9.
Mellan denna arm och den bakre vältramen 4 är en hydraulcylinder 10 kopplad, vilken har till uppgift dels att svänga den främre vältramen 3 och därmed valsen 1 för kurv- tagningsändamål, dels att sidoförskjuta vältramarna i förhållande till varandra som visas i fig 3.Between this arm and the rear roller frame 4 a hydraulic cylinder 10 is connected, which has the task partly to pivot the front roller frame 3 and thus the roller 1 for cornering purposes, and partly to displace the roller frames laterally relative to each other as shown in Fig. 3.
För att möjliggöra denna kurvtagning och sidoförskjutning med hjälp av endast en hydraulcylinder är mellanstycket lâsbart i olika vinkellägen i förhållande till den främre vältramen 3. Läsningen genomförs enligt uppfinningen med hjälp av en lâssprint 11, vilken är fjäderbelastad genom en fjäder 12 och vilken samverkar med hålet A på mellanstycket 6 och hålen a, b, c i ett med den främre ramen 3 fast förbundet och mot den bakre ramen 4 utskjutande parti 13.To enable this cornering and lateral displacement by means of only one hydraulic cylinder, the intermediate piece is lockable in different angular positions in relation to the front roller frame 3. The reading is carried out according to the invention by means of a locking pin 11, which is spring-loaded through a spring 12 and which cooperates with the hole. A on the intermediate piece 6 and the holes a, b, c in a portion 13 fixedly connected to the front frame 3 and projecting towards the rear frame 4.
Fjädern 12 håller sprinten 11 automatiskt i önskat låsläge. Sprinten 11 är emellertid via en wire 14 förbunden med en pedal 15 på förarplatsen och genom att trycka på pedalen 15 kan sprinten 11 dras ur sitt lâsläge.The spring 12 automatically holds the pin 11 in the desired locking position. However, the pin 11 is connected via a wire 14 to a pedal 15 in the driver's seat and by pressing the pedal 15, the pin 11 can be pulled out of its locked position.
Vid normalkörning, dvs när de båda valsarna spårar, är mellanstycket 6 läst till den främre vältramen 3 med hjälp av lâssprinten 11 nerskjuten i hâl A pâ mellanstycket 6 och hålet b på den främre ramens utskjutande parti 13. Genom aktivering av hydraul- cylindern 10 vrider sig den främre vältramen kring tappen 8 och önskad körriktning på välten kan erhållas.During normal operation, ie when the two rollers are tracking, the intermediate piece 6 is read to the front roller frame 3 by means of the locking pin 11 shot down into hole A on the intermediate piece 6 and the hole b on the projecting portion 13 of the front frame. By activating the hydraulic cylinder 10 the front roller frame around the pin 8 and the desired direction of travel on the roller can be obtained.
När valsarna från normalläget skall sidoförskjutas, lossas sprinten 11 ur sitt läs- läge genom att föraren trampar på pedalen 15. Den främre vältramen 3 frigörs därvid från mellanstycket 6 och kan svänga relativt detta. Genom att i detta läge vrida på vältratten åt vänster eller höger, aktiveras hydraulcylindern 10 och den främre vältramen vrider sig runt tappen 7. Med opåverkad pedal 15 kan låssprinten 11 inta nytt lâsläge, exempelvis det som visas i fig 3. 8200505-.9 Va1sarna_ÉÉïd§rvid sidoförskjutna i förhàïïande ti11 varandra, och genom att dç d__hà11s kvar Ä-detta läge med hjäïp av Tåšsprinten 11, kan hydrauïcyïíndern 10 akti- veras genom vridningsrörelser på väïtratten, och på saumw sätt som vid normaïkörning vrider sig därvid den främre väïtram 3 kring tappen 8.When the rollers are to be displaced laterally from the normal position, the pin 11 is released from its reading position by the driver depressing the pedal 15. The front roller frame 3 is thereby released from the intermediate piece 6 and can pivot relative thereto. By turning the roller funnel to the left or right in this position, the hydraulic cylinder 10 is activated and the front roller frame rotates around the pin 7. With unaffected pedal 15, the locking pin 11 can assume a new locking position, for example that shown in Fig. 3. 8200505-.9 Va1sarna_ÉÉïd In the case of lateral displacements in relation to each other, and by remaining in this position with the aid of the toe pin 11, the hydraulic cylinder 10 can be activated by rotational movements on the water wheel, and in the same way as in normal driving tap 8.
