VEHICLE WHEEL
Background of the Invention The present invention relates to a vehicle wheel having a rigid rim on which can be mounted a pneumatic vehicle -tire which is made of rubber Go rubber-like material and has a carcass which is anchored in the tire beads by being looped around pull-resistant and compression-resistant bead cores; the rim is provided with essentially radially inwardly extending rim flanges, the beads of the tire are secured on the radially inner periphery of the rim, and, next to each tire bead, there is disposed a respective mounting area having a deep bed for receiving an annular member.
A vehicle wheel of this type, which is distinguished by a good riding behavior and a high functional reliability in the event of a blow-out or flat tire, was proposed in US. Patent 4,563,042, and belonging to the Assignee of the present application. The filler ring described in this previous application is made of rubber or foam material, and fills the space axially inwardly of the tire bead in a wheel of the -type described in German Offenlegungsschrift 30 00 428.5 or German Offenlegungsschrift 31 45 252, both of which belong to the Assignee of the present application. This ` 12 3 filler ring primarily serves to prevent the punter-lion of spray and dirt into the endangered space, but can also serve in part as a securing element to prevent shifting of the tire bead in certain drive situations. This can also be of significance during safety tests where, among other things, the so-called blowout pressure is determined.
With vehicle wheels of the aforementioned general type, in addition to a blowout of the tire, a radially inward bending of the tire beads could also be encountered.
It is therefore an object of the present invention to further improve the bead and rim flange regions of a vehicle wheel of the alone-mentioned general type in such a way that the safety threshold relative to the blow-out pressure is even greater than that of conventional vehicle wheels or tires.
Brief Description of the Drawings This object, and other objects and advantages of the present invention, will appear more clearly from the following specification in conjunjunction with the accompanying drawings, in which:
Figure 1 is a radial partial section through one inventive embodiment of a vehicle wheel having a first securing ring;
Figure 2 is an enlarged partial section
VEHICLE WHEEL

A vehicle wheel of this type, which is distinguished by a good riding behavior and a high functional reliability in the event of a blow-out or flat tire, was proposed in US. Patent 4,563,042, and belonging to the Assignee of the present application. The filler ring described in this previous application is made of rubber or foam material, and fills the space axially inwardly of the tire bead in a wheel of the -type described in German Offenlegungsschrift 30 00 428.5 or German Offenlegungsschrift 31 45 252, both of which belong to the Assignee of the present application.

With vehicle wheels of the aforementioned general type, in addition to a blowout of the tire, a radially inward bending of the tire beads could also be encountered.
It is therefore an object of the present invention to further improve the bead and rim flange regions of a vehicle wheel of the alone-mentioned general type in such a way that the safety threshold relative to the blow-out pressure is even greater than that of conventional vehicle wheels or tires.
Brief Description of the Drawings This object, and other objects and advantages of the present invention, will appear more clearly from the following specification in conjunjunction with the accompanying drawings, in which:
Figure 1 is a radial partial section through one inventive embodiment of a vehicle wheel having a first securing ring;
Figure 2 is an enlarged partial section
2 --1231~)36 of the vehicle wheel of Figure l;
Figure 3 is a partial radial section : through another inventive embodiment of a vehicle wheel having a further securing ring which in the circumferential direction is toothed with the rim well and with the tire bead;
Figure 4 is a partial sectional view which extends in the circumferential direction of the wheel and is taken along line IV-IV in Fig. 3; and Figure S is a partial radial section of a vehicle wheel having a securing ring which conforms to that of Figure 1, however with a rim which has a drop-center on its radially outer side.
Summary of the Invention By one aspect of this invention, there is pro-voided a vehicle wheel having a rigid rim on which can be mounted a pneumatic vehicle tire which is made of rubber or rubber-like material and has a carcass which is anchored in the tire beads by being looped around pull-resistant and compression-resistant bead cores; the rim is provided with essentially radially inwardly extending rim flanges, the beads of said tire are secured on the radially inner periphery of said rim, and, next to each of said tire beads, there is disposed a respective mounting area having a deep bed for receiving an annular member; the improvement wherein: each of said rim flanges, on ~231036 its axially inner side, is provided with an undercut which forms a space in which is accommodated a portion of a tire bead and a portion of the bead core of that bead; and each annular member is in the o'er of a securing ring having such resistance to collapse, and such inherent stability, that in con-junction with the end of the associated rim flange, said securing ring exerts a wedging action on its tire bead.
- pa -~L23~036 tire bead, and above all a portion of the pull-resistant and compression-resistant bead core, pro-jets into the space formed by the undercut, an increased reliability is already achieved to the extent that when stress of the lower tire side wall is en-countered as a result of excessive air or water pros-sure, the tire bead cannot shift radially inwardly.
Such a movement could simultaneously lead to an axially inward shifting of the tire bead. This in turn is prevented by the further measure of filling the mounting area with an annular member which is resistant to collapse and has inherent stability.
In this arrangement, the annular member, which will subsequently be referred to as a securing ring, is disposed so tightly between the rim well and the wall of the tire bead that no significant axially inward displacement of the tire bead is possible.
In the contact region, the side walls of the securing ring and of the tire bead are constructed in such a way, for example extending vertically, i.e. radially, that when stress is encountered on the lower side wall of the tire, the tire bead, as a result of the undercut of the rim flange, is wedged continuously more markedly between the rim flange and the securing ring.
-` ~231036 Description of Preferred Embodiments Preferring now to the drawings in detail, Figure 1 illustrates a vehicle wheel and tire assembly having an installed securing ring 1. The pneumatic vehicle tire which is used is comprised essentially of rubber or rubber-like materials, and has a radial carcass 2; this carcass could also be a bias carcass.
The ends of the carcass 2 are anchored in the beads 4 by being looped around pull-resistant and compression-resistant bead cores 3. Disposed below the tread 5 and between this tread and the carcass 2 is a belt 6 which is pull-resistant in the circumferential direct lion, comprises two or more cord fabric plies, and effects lateral stabilization of the tire body. The inner surface of the tire, approximately in the region of the tread 5, is additionally provided with a thin sliding-contact layer 7 which makes it possible to support the tire on the rim ring 8 with limited friction in the event of a blow-out or flat tire.
The one-piece rim has a rim ring 8 which is preferably made of metal and is welded onto a rim well 9. Zen viewed in cross-section, the sides of the rim ring 8 end in rim flanges 10, which Essex-tidally extend radially inwardly. Disposed next to each of the rim flanges 10, on the radially inner .
~L~3~036 periphery of the rim ring 8, is a respective seating surface 11 for one of the tire beads 4. Disposed next to, and axially inwardly of, each of the seating surfaces 11 is a deep bed or recessed mounting port lion 12 for the respective tire beads 4. The radially outer portions of the rim ring 8 are constructed as support surfaces for the tire to support the latter in the event of a blow-out or loss of pressure. The U-shaped interior of the rim well 9 is filled with hard foam material 13, so that no dirt and spray can accumulate there.
In its radially inner portion, each rim flange 10 is curved axially inwardly, so that an arcuate undercut results between the tip or end 14 of the rim flange, and the associated seating surface 11 for the tire bead 4. The space formed by the under-cut is limited axially inwardly by a plane 15 which is parallel to the central plane of the tire; this space accommodates a portion of the tire bead 4 and a portion of the bead core 3. With regard to Sacramento, and from the standpoint of being able to easily mount the tire, it has proven to be expedient to place one-fourth to one-half of the diameter "d" of the bead core 3 into the space formed by the undercut (Figure 2).
Disposed between each tire bead 4 and the rim well 9 is one of the securing rings 1, which ,, lZ3~036 has an essentially rectangular cross-section, and can comprise one or more parts. In the illustrated embodiment, the securing ring 1 is made in one piece.
Louvre, at one point the ring 1 is cut apart or separated, so that the diameter of the ring can be altered during mounting. After mounting is completed, the ends of the ring can be placed fleshly against one another and interconnected by means of a bracket or strap. The securing ring 1 can also be mounted on the rim well 9 with the aid of a circumferential shoulder or boss (shown in dot-dash lines).
The securing ring 1 comprises an inner tubular or hollow core member 16 of spring steel, and a sheathing layer 17 of rubber. The hollow space 18 in the middle of the ring 1 reduces the weight there-of. A circumferential lip 19 on the hollow core member 16 serves for additionally wedging the bead 4, but can also be dispensed with, The hardness of the rubber of the sheathing layer 17 is such that on the one hand no significant compression is possible when a tire bead 4 is stressed, and that on the other hand a possibly present projection 20 can be shoved past the tire bead 4 during mounting. It would also be possible to make the projection 20 and the adjacent portion of a softer rubber. The securing ring 1 can, of course, also be made of a suitable synthetic material.
,. .
~L23~036 In the wheel and tire assembly illustrated in Figure 3, the securing ring 1' comprises a single material, namely a rubber having a hardness of greater than 90 Shore A, or a synthetic material, and it also has a hollow space 18 for reducing the weight. Iota differentiates this embodiment from that described in connection with Figures 1 and 2 is that the securing ring 1' is provided with means which assure a reliable transfer of force between the tire and the rim, even in the event of a blow-: out or flat tire. For this purpose, the axially inner side of the securing ring 1' is provided in the circumferential direction with alternating pro-sections 21 and grooves, which form a sort of tooth-gear mechanism with corresponding grooves and teeth 22 provided on the rim well 9 (Figure 4). The other side of the securing ring 1' is also frictional-lye connected with the tire bead 4 by means of a fine cogging 23. In all other respects, the construction and operation of the securing ring 1' and of the no-mining parts of the vehicle wheel of the embodiment shown in Figures 3 and 4 correspond to those described in connection with the embodiment of Figures 1 and 2.
The vehicle wheel shown in Figure 5 differs from that of Figures 1 and 2 merely in that the radially outer side of the rim ring 8 is provided with a conventional drop-center 24. In place of the legs : . - 8 -123~36 of the U-shaped rim well 9, the vertical, i.e. radial-lye extending, walls of the drop-center 24 now serve for the axial inner support of the securing ring 1.
It should be noted that the inventive vehicle wheel and tire assemblies can be utilized not only with passenger cars, but also with trucks and other vehicles.
The present invention is, of course, in no way restricted to the specific disclosure of the specification and drawings, but also encompasses any modifications within the scope of the appended claim .
