Description

[0025] The invention will be explained in greater detail on the basis of an exemplary embodiment. In the drawings:

[0026] FIG. 1 shows a diagram of a two-wheeled-vehicle tire according to the invention with a device for generating rotation-dependent signals adhesively bonded thereon.

[0027] FIG. 2 shows a diagram of a two-wheeled-vehicle tire according to the invention with a device for generating rotation-dependent signals vulcanized therein.

[0028] FIG. 3 shows a diagram of an enlarged illustration of the embodiment as per FIG. 2.

[0029] FIG. 4 shows a diagram of an adapter in an embodiment in which the holding element, adapter and signal-generating element form a spike.

[0030] FIG. 5 shows a schematic diagram of an embodiment in which the signal-generating element is detachably connected to the adapter.

[0031] FIGS. 6a to 6c show an embodiment of a two-wheeled-vehicle tire according to the invention, in which the holding element is in the form of a bead or protective ring which surrounds the signal-generating element.

[0032] FIG. 1 shows a diagram of a two-wheeled-vehicle tire 1 on a wheel rim 10 in section, having a device 2 for generating rotation-dependent signals, wherein the device 2 is connected to the tire sidewall 9 by adhesive bonding. FIG. 2 shows a corresponding two-wheeled-vehicle tire 3 in section, wherein a device 4 for generating rotation-dependent signals is connected to the tire sidewall 7 by vulcanization.

[0033] FIG. 3 shows, likewise in section and in a diagram, an enlarged illustration of the embodiment. It is possible firstly to see the signal-generating element 6, which is in the form of a permanent magnet and received in an adapter 5, wherein here, the signal-generating element 6 together with the adapter 5 composed of wear-resistant material are received in a holding element 8 which is connected in non-positively locking fashion to the tire body or to the tire side wall 7 by vulcanization.

[0034] The holding element 8, like the holding element 12, is arranged, substantially outside the tire carcass 11, in or on the sidewall 7, 9 of the tire, and the signal-generating element 6 is received in the holding element such that the signal-generating element 6 projects beyond the outer surface of the tire. The material of the holding elements 8 and 12 corresponds to the sidewall material, that is to say is produced from rubber. Here, the holding elements 8 and 12 are in the form of sidewall reinforcements.

[0035] FIG. 4 shows, in a diagram, a further adapter 13, in this case without an inserted magnet as signal-generating element, designed for an embodiment in which holding element, possibly adapter and signal-generating element form a spike.

[0036] FIG. 5 shows, in a schematic diagram, an embodiment in which the signal-generating element 14 in the form of a magnet is connected detachably, specifically by way of screw action, to the adapter 15. Here, the signal-generating element 14 has an external thread on a part of its outer circumference, whereas the adapter 15 is equipped with an internal thread and with a thickened head 16 which can be screwed into the complementary recess of the holder 17.

[0037] This may also be performed in automated fashion. For this purpose, the adapter 15 and signal-generating element 14 are firstly screwed together. Thereafter, the part thus screwed together is shot into the recess of the holder 17 by way of a specially designed pistol.

[0038] The entire system is indicated in FIGS. 1 and 2. The system, used on a two-wheeled vehicle (not illustrated in any more detail), has a two-wheeled-vehicle tire 1, 3 according to the invention and a sensor 18, 19 which is arranged on a fork or swinging fork (likewise not illustrated), which sensor detects the rotation-dependent signals of the signal-generating element and provides said signals as input signals to the controller.

[0039] FIGS. 6a to 6c show an embodiment of a two-wheeled-vehicle tire according to the invention in which the holding element is in the form of a bead or protective ring 20 which partially surrounds the signal-generating element and the adapter. It is thus possible for shearing off, for example against curbs, to be prevented.

[0040] Here, FIG. 6c shows a side view of the two-wheeled-vehicle tire according to the invention, in which the bead 20 is arranged in the transition region between tread and side wall. In the embodiment shown here, the bead is arranged such that, as the two-wheeled-vehicle tire rotates, said bead is always oriented toward the underlying surface, such that any impacts against curbs or edges of road unevennesses does not lead to damage to the signal-generating element. FIG. 6b shows a view of the tread from above. In this case too, the projecting bead 20 can be clearly seen. FIG. 6a shows a view out of the wheel plane, that is to say a view toward the wheel rim from the wheel hub.

[0041] Said means for protecting against shearing off is, in this embodiment, during traveling operation, provided only toward the underlying surface, that is to say only at those points of the tire outer wall at which shearing off can actually occur.
