Description

" Fully mature" η made of rubber or other blastomeres, especially for vehicle wheels *

The invention relates to a toll tire from Summi or others Ilaatomeren, especially for bicycles bit one for assembly PuB formed on a normal pneumatic tire rim.

With the known toll tires of this type »shares the trouble-free and assembly that can be carried out with the least possible aids with simultaneous misleading of a firm fit of the sting on the rim is a problem that has not yet been solved to the greatest satisfaction. To ensure a secure fit a solid tire on the Pe Ige it is conventionally necessary To bring the soap onto the dough with a certain gate tension, which in most cases requires the use of τοη aids such as mounting rings and high machine-made pressures Requires · The desired advantage of a non-slip side seat can therefore only be achieved at the expense of a disadvantage that is very reluctantly accepted

In another known construction, there are also short, iron wedges in the transverse direction on the dough and smooth attached to this distributed to ensure a tight fit of the igloo to achieve · But this has the disadvantage that on the one hand it is solo Solid tires need special figs again, on which, if necessary, · pneumatic tires can no longer be mounted and on the other hand the soap The foot is damaged by the sharp iron wedges and must be made of a relatively hard material in order to achieve a sufficient To find support on the wedge ribs

The purpose of the present invention is to take these Haohttile Ensuring a reliable bsifentities to fix whatever According to the invention, it is achieved that the base of the foot on both Side parts lying in the dough by one or more, one closed, extending in the circumference direction of the helping Hing-forming steel wires or wire bundles embedded in a respective bead made of rubberized Oord fabric

armored and mix the beads with a running all around Inauguration provided 1st «

The steel wire reinforcement embedded in beads in connection with the arching of the tire foot guarantees ready »in the unloaded Condition of the tire a non-slip seat on the rim, so that a preload, as is generally the case with solid tires is considered indispensable, is omitted or can be kept low, which has the advantage that an inventive fl trained solid tires with the tools and the time required, as they are also common with pneumatic tires, on the rim can be mounted. When the tire is loaded, a spreading effect is achieved due to the bulge in the tire foot, which differs from the center of the tire foot with simultaneous decrease of the SeWölbehohlraumes on both sides on the beads and thus acts as pressure against the rim horns

According to the invention, the tire part between the two beads is advantageously made of rubber with a very high modulus and strength elastic restoring force, which increases the spreading effect, while the width of the curvature all around is preferably the The width or approximately the width of the horizontally extending hook part of the tapered shoulder rim corresponds to · Sin further The feature of the invention is that the height of the curvature is advantageously dimensioned so that with the prescribed maximum load of the tire the vault wall rests on the rim

The drawing shows two exemplary embodiments of the subject matter of the invention shown, namely point

toeetehende solid tires 4- is essentially e-shape in its cross-section those of a pneumatic tire »modeled on it. The tire foot is reinforced on both side parts lying in the dough 5 by a steel wire 6, which is embedded in an aua rubberized Oordebt existing bead 7ι in circumferential direction extends and forms a closed Hing · Between the beads 6 is the tire foot according to the invention with an all around LinwOlbung 8 provided, the width of which or approximately that of the horizontally extending surface part χ the tapered shoulder rim 5 corresponds. The height of the bulge θ is two-dimensionally dimensioned so that with the prescribed maximum load of the tire, as shown in Fig. 1, the arch wall 9 rests on rim 5 *

The toll tire 4 has an inside diameter which is the same as the outside diameter the tapered shoulder rim 5 corresponds or is kept only a little smaller, so that the mounting of the tire ripen in the same way and with the same means as with air, can therefore be carried out with little or no gate tension · Hachdem the help is pressed onto the rim and by the wedge ring 10, the Seitenriug 11 and the Versohlußring is clamped against the rim flange 13, a non-slip bit is guaranteed on the rim even in the unloaded state (Fig. 2). When the tire is loaded (Fig. 1), the bulge 8 exerts a spreading effect on the tire foot, which, starting from the center of the tire foot, takes place laterally in the direction of the two beads 6 and the beads against the Rim flanges press · With increasing load on the tire, the slip resistance is improved. This spreading effect will further increased by the fact that the tire part 14 is between the two Bulges made of a rubber with a very high modulus and strong elastic restoring force, i.e. made of a rubber that e.g. a module of 140 kg at 300 pounds elongation (according to DIN 53 504, Bl * 2) and has a rebound resilience of 50 Jt.

The running cushion 15 can differ from the tire part 14 Have properties. However, as shown in Fig. 3, the solid tire can also consist of the same type of material throughout, whereby the properties listed for the tire part 14
