Die Erfindung bezieht sich auf Räder mit an einem inneren, mit der Nabe starr verbundenen Radkranz angeordneten Federn, die mittels Gleitschuhe ihren Druck auf einen äußeren, mit dem Radreifen starr verbundenen. Radkranz übertragen und letzteren durch die Reibung zwischen, den Gleitschuhen und ■ deren Gleitbahn mitnehmen. Gegenstand der Erfindung ist die besondere Ausführungsform, bei ίο der die Übertragung, der Federkraft auf die Gleitschuhe unter Vermittlung von in den Gleitschuhen angebrachten Rollenlagern erfolgt. The invention relates to wheels with an inner one rigidly connected to the hub Springs arranged on the wheel rim, which exert their pressure on an outer, rigidly connected to the wheel tire. Transferring the rim and the latter through friction between, the sliding shoes and ■ their slide. Subject of the invention is the special embodiment, with ίο the transmission, the spring force on the Slide shoes takes place through the intermediary of roller bearings mounted in the slide shoes.

Die Enden der Speichen α (Fig. 1) stecken in Hülsen b. Mit letzteren wird der Metallreifen c durch Schrauben d verbunden, die durch Löcher des Reifens gesteckt sind und in dem Boden der Hülsen b ihre Mutter finden. Die Schrauben- dienen zugleich zur Befestigung der geschichteten Blattfedern f, die von dem Schraubenkopf / gehalten werden.The ends of the spokes α (Fig. 1) are inserted into sleeves b. The metal tire c is connected to the latter by screws d which are inserted through holes in the tire and find their nut in the bottom of the sleeves b. The screws also serve to fasten the layered leaf springs f, which are held by the screw head /.

Der Randkranz besteht im wesentlichen aus . der starren Felge g (Fig. 1), welche an der Außenseite mit einem Voll- oder Hohlgummireifen oder auch mit einem Lederreifen h bekleidet ist, während an der Innenseite in Richtung des Umfatiges verschiebbare Klötze i angeordnet sind. Die Enden der Blattfedern f stützen sich mittels Platten 6 (Fig. 3) gegen Rollen I₁ die in einem gemeinsamen Rahmen s gelagert sind und mit diesem in den Klötzen i gleiten können. Beim Auftreten von Stoßen wird die Bewegung der Rahmen gegenüber den Klötzen durch kleine Spiralfedern begrenzt.The rim consists essentially of. the rigid rim g (Fig. 1), which is clad on the outside with a solid or hollow rubber tire or with a leather tire h , while on the inside in the direction of the Umfatiges movable blocks i are arranged. The ends of the leaf springs f are supported by means of plates 6 (FIG. 3) against rollers I ₁ which are mounted in a common frame s and can slide with this in the blocks i. When bumps occur, the movement of the frame in relation to the blocks is limited by small spiral springs.

Der Radkranz ist mit zwei seitlich angeordneten - ringförmigen Deckplatten η und ο ausgestattet (Fig. 2). Die Deckplatte η ist mittels Schrauben oder Nieten an der Felge g befestigt, die Deckplatte 0 ist dagegen zur Erleichterung von Ausbesserungen abnehmbar mittels Schraubenmuttern p befestigt.The wheel rim is equipped with two laterally arranged - ring-shaped cover plates η and ο (Fig. 2). The cover plate η is fastened to the rim g by means of screws or rivets, the cover plate 0 , on the other hand, is fastened removably by means of screw nuts p to facilitate repairs.

Zu beiden Seiten des Metallreifens c befinden sich Lederstreifen q,r (Fig. 2), welche sich gegen die Seitenringe n, 0 legen und das Eintreten von Sand oder Schmutz in den Federraum des Radkranzes verhindern. Beim Drehen des Rades erfolgt die Mitnahme der Felge sowohl durch die Reibung zwischen der Grundfläche der Klötze i und der Innenfläche der Felge g als auch durch eine Vorrichtung, welche die Seitenflächen dieser Klötze an dieOn both sides of the metal tire c there are leather strips q, r (Fig. 2), which lie against the side rings n, 0 and prevent the entry of sand or dirt into the spring chamber of the wheel rim. When the wheel is turned, the rim is entrained both by the friction between the base surface of the blocks i and the inner surface of the rim g and by a device which attaches the side surfaces of these blocks to the

Claims

Pressing the side surfaces of the rim. This device, which can be seen from FIGS. 3, 4 and 5 is also used to limit the displacement of the rollers in the slide shoe. It is trained in the following way:

Joint parts 2, 2 ' and 3, 3' are articulated to the screw head 1 by means of a bolt 4 which is inserted into elongated openings in the joint parts.

The blocks % (Fig. 3 and 4) consist of two elongated parts i ' and i " (Fig. 4), which are interconnected by the bolts 5, 5'. The blocks i are, as mentioned, in the direction of the Circumference on the rim and can be driven apart by a means, which will be discussed in the following, and clamped on the sides of the Fekje.

The rollers I against which the plates 6

20. support, are provided in the middle with a constriction / '(Fig. 4), and the frame accommodating the rollers ζ has incisions at the corresponding points in which a rib of part V engages. This rib is used to guide the roles and the frame z.

The two parts V and i " move apart in the following way:
On the axis 5 between the two members 2, 2 'a sleeve 7 (Fig. 4) ending in an arm IO (Fig. 3) is loosely arranged, which is provided with ratchet teeth 8, which are provided in corresponding, on the member 2' Teeth 9 grip. The sleeve 7 is connected to a piston (FIGS. 3 and 5) by means of the arms 10, 10 ′, which are rigidly coupled to one another, which can move in a cylinder 11 under the action of a spring. The cylinder 11 is connected to two pivot pins which are mounted in the links 2 and 2 '. The arm ίο 'carries a leaf spring 12 on its lower part, which is supported against the rim g and whose tension in the position shown in FIG. 3' is less than that of the spring enclosed in the cylinder 11. The arm 10 'carries a stud screw 10 "which engages through an arcuate slot provided in the arm 10. This arrangement allows the inclination of the arm 10 with respect to io' and thereby the tension of the spring 12 with respect to that of the spring enclosed in the cylinder as desired and thereby determine the point in time at which the two sliding shoes should come apart.A dead gear can also easily be eliminated if the sliding shoes have been worn after some time.

As soon as the spring f bends, the bolt 4 moves downwards and takes the links 2 and 2 ' with it as it moves. At the beginning of this movement, the arm 10 is also taken along, and the two sleeves 7 and 9 rotate about the axis 5. As soon as the spring 12 is tensioned and exerts a force on the arm 10 'which is equal to or greater than the force which is exerted in the opposite direction by the spring of the cylinder ti, this arm 10 'stops, so that the cylinder 11 alone continues to move downwards with respect to the piston while the spring located therein is tensioned . Since the arm 10, which is firmly connected to 10 ', and the sleeve 7 can no longer perform any further movement, the link 2', on the other hand, continues to move downwards by still rotating the sleeve 9, the sleeve 7 moves and the sleeve 9 apart as a result of the shape of its teeth. Here, the part V of the block is displaced in the direction of the arrow χ (FIG. 4) and the parts i ″ in the direction of the arrow y . Since the play that exists between the edges of the rim and the sides of the block is relatively limited, parts % ',% "are pressed against the sides of the rim after a short time.

There is then the entrainment of the rim not only through the friction "between the Blocks and the inner surface of the rim, but also by the clamping effect of this Blocks on the sides.

In the embodiment according to FIG. 6, the spokes 13 are tubular. In A piston 14 under the action of the helical spring 20 can displace these tubes be, which carries a plate 15 at its outer ends, which on the rollers a carriage 16 arranged in the block 17 rolls. -

The blocks 17 loosely mounted in the outer rim are made by crossing handlebars 19, 19 'connected to the parts 18, which are attached to the ends of the tubes 13.

In this embodiment, the rim is entrained by the friction between the blocks and the outer rim, which is disfigured by the fact that the links 19, 19 ', when the rim c shifts outwards under the action of the load, fix the blocks press against the outer rim.
