  Befestigungseinrichtung für ein an einem Traktorrad anzuordnendes Gitterrad 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 der Befestigungsplatte 6 diametral angeordneten Spannbügels 7 umgreifen. An der mit abstehenden Betätigungsarmen 11   versehenen Befestigungsmutter   10 ist ein federbelasteter, die Stellung der Mutter fixierender, d. h. fallweise in deren Auflager 13 am Bandeisen 3 einrastender Sicherheitsbolzen 12 angeordnet. Eine Feder 14 bringt ihn zum fallweisen Einrasten in die Bohrung 13 des Bandeisens 3 (Fig. 4 unten). Aus der Einrastlage des Bolzens 12 gezogen, wird das abgewinkelte Ende von dessen Spindel auf den Betätigungsarm 11 der Mutter 10 aufgelegt (Fig. 4 oben).

   Die freien   Enden 3'der Bandeisenträger 3 sind mit dem Gitterrad 1 verbunden und versteifen die kup -   pelartige Tragkonstruktion 3 gegen das Rad, die überdies mit den Speichen 5, 5'am Rad 1 befestigt ist. Bei Anziehen der Befestigungsmutter 10 greift der Befestigungsring 2 in den ringförmigen Ansatz 6'der Befestigungsplatte 6 ein, wobei infolge der Federwirkung der im Zentrum durchgebogenen kreuzförmigen Tragkonstruktion 3 der Befestigungsring 2 an jenen vier Stellen, an denen er mit dem Bandeisen 3 verschweisst ist, nach aussen gedrängt wird und dadurch am ringförmigen Ansatz   6'der   Befestigungsplatte 6 besonders fest zum Anliegen kommt. Erfindungsgemäss wird das Gitterrad besonders schnell und fest mit dem Traktorrad verbunden.

   Auch ist es möglich, Gitterräder verschiedener Dimensionen, jedoch versehen mit dem gleichen Befestigungsring 2, mit Hilfe der Befestigungsplatte 6 bzw. deren verschiedenen Radbolzenbohrungen 15 an jedem Traktor leicht zu befestigen. 



   PATENTANSPRÜCHE : 
1. Befestigungseinrichtung für ein an einem Traktorrad anzuordnendes Gitterrad, versehen mit einer zentral angeordneten aus Zuganker und Befestigungsmutter bestehenden Spannvorrichtung, dadurch gekennzeichnet, dass sie eine mittels der Radbolzen (16) am Traktorrad festzuschraubende Beestigungsplatte (6) aufweist, die mit einen zum Eingriff für das hakenförmige Ende des Zugankers (9) bestimmten Spannbügel (7) versehen ist und nahe ihrem äusseren Rand einen ringförmigen Steg   (6')   besitzt, dass sie ferner aus einer zentral im Gitterrad   (1)   angeordneten kuppelartigen Tragkonstruktion besteht, die in Kreuzform angeordnete, an den Speichen (5, 5') des Gitterrades festgeschweisste, gewölbte Bandeisenträger (3) aufweist,

   deren konkave Seite bei montiertem Gitterrad dem Traktorrad zugewendet ist und die nahe ihren traktorseitigen Enden einen zum zentrierenden Eingriff mit dem Steg (6') der Befestigungsplatte (6) bestimmten Ring (2) tragen, und dass an dem die Mitte der kuppelartigen Tragkonstruktion bil-   denden Kreuzungspunkt   der Bandeisenträger (3) eine Bohrung zum Durchtritt des Gewindebolzens des Zugankers (9) vorgesehen ist, auf dessen an der Aussenseite der Tragkonstruktion vorragendes Ende die zum Festspannen des Gitterrades am Traktorrad dienende Befestigungsmutter (10) aufgeschraubt ist.

  Fastening device for a grid wheel to be arranged on a tractor wheel
 EMI1.1
 

 <Desc / Clms Page number 2>

 the mounting plate 6 grip around the diametrically arranged clamping bracket 7. A spring-loaded fastening nut 10, which is provided with protruding actuating arms 11, fixes the position of the nut, i. H. occasionally arranged in their support 13 on the iron band 3 locking safety bolts 12. A spring 14 causes it to snap into the hole 13 of the iron band 3 (FIG. 4 below). Pulled out of the locked position of the bolt 12, the angled end of its spindle is placed on the actuating arm 11 of the nut 10 (Fig. 4 above).

   The free ends 3 ′ of the band iron girders 3 are connected to the lattice wheel 1 and stiffen the dome-like support structure 3 against the wheel, which is also attached to the wheel 1 with the spokes 5, 5 ′. When the fastening nut 10 is tightened, the fastening ring 2 engages in the annular extension 6 ′ of the fastening plate 6, with the fastening ring 2 following the four points where it is welded to the iron band 3 due to the spring action of the cross-shaped support structure 3 which is bent in the center is pushed outside and thereby comes to rest particularly firmly on the annular extension 6 'of the fastening plate 6. According to the invention, the cage wheel is connected to the tractor wheel particularly quickly and firmly.

   It is also possible to easily fasten cage wheels of different dimensions, but provided with the same fastening ring 2, to each tractor with the aid of the fastening plate 6 or its various wheel bolt bores 15.



   PATENT CLAIMS:
1. Fastening device for a cage wheel to be arranged on a tractor wheel, provided with a centrally arranged tensioning device consisting of tie rods and fastening nuts, characterized in that it has a fastening plate (6) to be screwed onto the tractor wheel by means of the wheel bolts (16), which has a fastening plate (6) which is to engage for the hook-shaped end of the tie rod (9) is provided with a certain clamping bracket (7) and has an annular web (6 ') near its outer edge, that it also consists of a dome-like support structure arranged centrally in the lattice wheel (1), which is arranged in a cross shape, has arched iron straps (3) welded to the spokes (5, 5 ') of the lattice wheel,

   whose concave side faces the tractor wheel when the cage wheel is mounted and which, near their tractor-side ends, carry a ring (2) intended for centering engagement with the web (6 ') of the fastening plate (6), and on which the center of the dome-like support structure is formed. At the intersection of the iron bars (3) a hole is provided for the threaded bolt of the tie rod (9) to pass through, on whose end protruding on the outside of the supporting structure the fastening nut (10) used to clamp the grid wheel to the tractor wheel is screwed.
