Tire module with piezoelectric transducer

#Field of the Invention

#The invention relates to an arrangement comprising a tire module for attachment to the inner side of a pneumatic tire for vehicles, and a cover which accommodates the tire module.

#Background of the Invention

#The accompanying drawings illustrate the invention. In such drawings:

#FIG. 1 shows a vertical section through an arrangement comprising a tire module and a cover, which is fastened to the inner side of a tire, according to the prior art;

#FIG. 2 shows a vertical section corresponding to FIG. 1 through an arrangement according to the invention;

#Parts that are identical or similar are labelled in the five figures with the same reference numerals.

#FIG. 1 shows, enlarged and schematically, a known and substantially cylindrical tire module 1 in a cover 2, which accommodates the tire module 1 without play. The tire module 1 has a top side 4 and an underside 5, which rests in the installed state against the inner side 6 of the tread of a tire 7. The cover 2 has a top part 8, which rests on the top side 4 of the tire module 1, and a substantially cylindrical jacket 9, which encloses the tire module 1 and transitions into an outwardly extending flange 10, which has an underside 11, which faces the inner side 6 of the tread of the tire 7 and is adhesively bonded to the inner side 6 of the tire 7. The adhesive layer 12 is shown having a greatly exaggerated thickness.

#The cover 2 is made of an elastomeric material. The inner height thereof, which is measured including the adhesive layer 12, is that much smaller than the height H of the tire module 1 that the flange 10 of the cover 2 can be adhesively bonded all-over to the inner side 6 of the tire 7 only when the inner height of the cover 2 is resiliently stretched such that the cover 2, after being fixedly connected to the inner side 6 of the tire 7, has a mechanical preload, by means of which the tire module 1 is pressed against the inner side 6 of the tire 7.
