TIRE MODULE WITH PIEZOELECTRIC TRANSDUCER

摘要

A tire module and cover for attachment to a pneumatic tire for vehicles is disclosed. The tire module has a device for measuring and/or monitoring the air pressure in the tire, a transmitter, a mechanical-electrical transducer, and an accumulator for electrical energy storage. The cover includes a flange which extends outwardly away from the tire module and has an underside for attachment to the inner side of the tire, said flange forming the edge of the interior space of the cover. The inner height of the cover may be less than or equal to the height of the tire module measured from the underside to the top side thereof. The flange has an inwardly directed projection which engages beneath the tire module. The underside of the tire module is higher up in the region of the flange projection as compared to a central underside region.

主权项

1. 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,
wherein the tire module comprises:
a top side and an underside;a device for measuring and/or monitoring the air pressure in the tire;a transmitter for transmitting radio signals that contain information on the air pressure in the tire;a mechanical-electrical transducer, which converts changes in the shape of the transducer caused by the rolling tire into electrical energy; andan accumulator for the electrical energy; and wherein the cover comprises:
a flange which extends outwardly away from the tire module and has an underside for attachment to the inner side of the tire, said flange forming the edge of the interior space of the cover, and the inner height of the cover is less than the height of the tire module measured from the underside to the top side thereof such that the tire module projects beyond the underside of the flange of the cover;wherein the flange has an inwardly directed projection which engages beneath the tire module, wherein the underside of the tire module lies higher up in the region of the inwardly directed projection of the flange than it does in a central region of the underside of the tire module.
