Tire Module and Tires Equipped Therewith
First Claim
1. A tire module for installation on an inner side of a pneumatic tire for vehicles, comprising:
- a device for measuring and/or monitoring of the air pressure in the tire;
a transmitter for transmitting radio signals containing information about the air pressure in the tire;
a mechanical-electrical converter having a bendable piezoelectric element, for converting, into electrical energy, and alternating deformations of the piezoelectric element caused by the rolling tire; and
a storage device for the electric energy, said storage device being is connected to the converter, the converter comprising a circular, disc-shaped, piezoelectric element (piezo disc) and an electrical voltage generated by the piezo effect is tapped at contact points, situated on opposite sides of the piezo disc.

Abstract
A tire module, for installation on an inner side of a pneumatic tire for vehicles, including a device for measuring and/or monitoring of the air pressure in the tire, a transmitter for transmitting radio signals, which contain information about the air pressure in the tire, a mechanical-electrical converter having a bendable piezoelectric element, which converts into electric energy alternating deformations of the piezoelectric element caused by the rolling tire, and a storage device for the electric energy, which is connected to the converter. The converter includes a circular, disc-shaped, piezoelectric element (piezo disc) on which an electrical voltage generated by the piezo effect is tapped at contact points, which are situated on opposite sides of the piezo disc.
