Example Embodiment

[0027] Figure 1 shows a section through a tire module 1 which is preferably arranged on the inner side of a pneumatic tire opposite the tread area. The shell member 5 has a groove in which one end of the spring member 2, which is a leaf spring in this embodiment, is clamped. On the end of the spring element 2 opposite the clamping end is provided a vibrating mass 3 which vibrates as a result of the mechanical impulses. The spring element 2 and the vibrating mass element 3 together form a spring-mass oscillator which moves oscillatingly in the housing 5 . Piezoelectric layers 4 are respectively provided on the top and bottom surfaces of the spring element 2 , which are suitably polarized and are provided with contact surfaces. The application is designed such that the deflection of the spring element 2 results in an elongation or compression of the piezoelectric layer 4 . An electrical voltage can be drawn from the contact surface, not shown, so that the kinetic energy caused...

Abstract

The invention relates to a tyre module for recording tyre condition variables, comprising a spring element (2) that is fixed on one side and a conversion unit (2, 3, 4, 6, 7), in which the displacement energy is converted into electric energy. The spring element (2) is configured as a rod spring, torsion spring or leaf spring and carries a seismic mass (3) on its free end. The spring element transmits acceleration steps of the seismic mass (3) to the conversion unit (2, 3, 4, 6, 7).

Description

technical field [0001] The invention relates to a tire module for measuring tire state quantities and to a pneumatic tire with such a tire module, which has a spring element compressed at one end and a conversion unit in which kinetic energy is converted into electrical energy. [0002] The invention is particularly suitable for determining the state quantity and performance of highway pavement with energy autonomous system. Background technique [0003] A system for determining operating parameters of vehicle tires is known from DE 4402136 A1, in which a sensor unit, an electronic processing unit and piezoelectric elements for supplying energy to other elements of the system are arranged on a support. The piezoelectric element has a multilayer structure. [0004] Furthermore, a device for supplying energy to sensors is known from DE 10103952 A1, which has an active piezoelectric transducer which can be deformed by a mechanical energy store and provides a corresponding vol...
