Description

20 25 30 35 447 557 kantspår 4. Det extra hjulet har en likadan fälg 5 och dessa fälgar förenas med varandra med hjälp av en Eörbindningsring 6. Denna ring består vid denna utföringsform av två delar, som förskjuts från varandra med hjälp av en länkmekanism 7 och en skruvmekanism 8. Ringen 6 kan även tänkas bestå av en, tre eller flera delar. Ringen 6 har utåt svängde kanter 9, som pressas mot spårens 4 botten med hjälp av länk- och skruvmekanismerna. 20 25 30 35 447 557 edge groove 4. The auxiliary wheel has a similar rim 5 and these rims are joined together by means of a Ear Connecting Ring 6. In this embodiment this ring consists of two parts, which are displaced from each other by means of a link mechanism 7. and a screw mechanism 8. The ring 6 may also consist of one, three or more parts. The ring 6 has outwardly pivoted edges 9, which are pressed against the bottom of the grooves 4 by means of the link and screw mechanisms.

Om hjulens fälgar är av olika storlek används en förbindingsring med i motsvarande grad olika stora kantflänsar 9. Ringen 6 kan även vara kantig, såsom framgår av fig. 3. Det går enklare att montera en sådan ring på hjulfälgarna, vilkas kantspår eventuellt kan ha inbuktningar förorsakade av stötar e.d.If the rims of the wheels are of different sizes, a connecting ring is used with correspondingly different edge flanges 9. The ring 6 can also be angular, as shown in Fig. 3. It is easier to mount such a ring on the wheel rims, the edge grooves of which may have indentations. caused by shocks ed

Den i fig. 4 och 5 visade konstruktionen uppvisar flera förbindningsele- ment 10 och dessa anpressas radiellt mot botten i spåren 4 på hjulfälgarna med hjälp av en särskild spännmekanism. Denna består av armar 11, 12 som är ledförbundna med fästelementen 10, skivor 13, 14 som förbinder de andra ändarna av dessa armar med varandra och en skruv 15, med hjälp av vilken skivorna 13 och 14 kan förskjutas antingen emot eller från varandra.The construction shown in Figs. 4 and 5 has several connecting elements 10 and these are pressed radially towards the bottom of the grooves 4 on the wheel rims by means of a special clamping mechanism. This consists of arms 11, 12 which are articulated to the fastening elements 10, discs 13, 14 which connect the other ends of these arms to each other and a screw 15, by means of which the discs 13 and 14 can be displaced either against or from each other.

När det extra hjulet fästs vid draghjulet förskjuts skivorna 13 och 14 från varandra, varvid armarna 11 och 12 drar förbindningselementen 10 mot mittaxeln och fästanordningen kan placeras mellan traktorhjulet och det extra hjulet. När skruven 15 spänns rör sig_förbindningselementen 10 från mittaxeln och tränger in i spåren 4 och åstadkommer ett förband.When the auxiliary wheel is attached to the towing wheel, the discs 13 and 14 are displaced apart, the arms 11 and 12 pulling the connecting elements 10 towards the central axis and the fastening device can be placed between the tractor wheel and the auxiliary wheel. When the screw 15 is tightened, the connecting elements 10 move from the central axis and penetrate into the grooves 4 and provide a connection.

I konstruktionen enligt fig. 6 och 7 är en stomskiva 17 fäst vid det extra hjulet med hjälp av skruvar.16. En spännskruv 18 och en av denna uppburen förbindningsskiva 19.är fästa vid stomskivan 17 och armar 20 som uppbär förbindníngselementen_10'är ledfästa vid skivan 19; Fast- monteringen sker genom att ställa det extra hjulet på rätt plats, var- efter armarna 20 bringas_att skjuta in förbindningselementen_10_i fälg- spåren 4 genom att spänna skruven 18.In the construction according to Figs. 6 and 7, a frame disc 17 is attached to the extra wheel by means of screws 16. A clamping screw 18 and a connecting plate 19 supported therefrom are attached to the body plate 17 and arms 20 supporting the connecting elements 10 are hinged to the plate 19; The mounting is done by placing the extra wheel in the right place, after which the arms 20 are caused to slide the connecting elements_10_ into the rim grooves 4 by tightening the screw 18.

Uppfinningens olika detaljer kan variera och avvika från de ovan be- skrivna detaljerna inom ramen för den i vidstående patentkrav defini- erade uppfinningstanken.The various details of the invention may vary and deviate from the details described above within the scope of the inventive concept defined in the appended claims.

Claims

447,557 Patent claims

Device for attaching a double wheel next to an actual wheel, in particular in connection with wheels on agricultural tractors, the wheel rim (3) being of such a construction that the rim edge pivots inwards and forms a groove (4) open towards the rim shaft. and by means of which device the fixing of the double wheel takes place by means of a fastening member (6, 10) consisting of one or more parts, characterized in that the edges (9) of the fastening member (6, 10) are directed outwards in such a way that they fit into the grooves (4) in both the rim (3) of the actual wheel and in the rim (5) of the double wheel, and that the locking of the double wheel to the actual wheel takes place by pressing the edges (9) of the fastening member (6, 10) into the grooves ( 4).

Device according to claim 1, characterized in that the fastening member (6) consists of one or more parts located one behind the other, which together form a ring of substantially the same size as the groove (4) of the rim (3, 5), and that devices (7, 8), by means of which the circumference of the fastening member can be increased so that its edges (9) press against the groove bottoms (4), are connected to the fastening member.

Device according to claim 2, characterized in that the circumference of the fastening member (6) is angular.

Device according to claim 1, characterized in that the number of fastening means (10) is three or more and they are displaced outwards by means of arms (11, 12) connected to them, which at the other end are supported in radial direction on flanges (13 , 14), which by means of a screw (15) can be moved closer to each other, so that the arms acting on each fastening member (10) approach each other and move the fastening member into the edge grooves of the rims (3, 5). (4).

Device according to claim 1, characterized in that a body part (17) is attached to the double wheel, in relation to which the fastening means (10) are made movable by means of a screw (18) and arms (19) in such a way , that the gripping parts of the fastening member are pushed into the edge grooves (4) in both the rim (3) of the actual wheel and in the rim (5) of the double wheel.
