TIRE ASSEMBLY WITH BUILT-IN ELECTRIC POWER GENERATION DEVICES Russian patent published in 2010 - IPC B60C23/04 

FIELD: transport.

SUBSTANCE: invention relates to designs of automotive tires with built-in electronic devices. Proposed tire assembly comprises one or more piezo-electric devices designed to generate electric discharge when tire is subjected to mechanical strain related with tire elements or wheel deflection. Said piezo-electric device can be built in several tire structures on different sections. Proposed piezo-electric device and electronic device related therewith can be inserted into tire crown or sides between external tread element, first and second steel breakers of breaker pad, carcass, tread section, internal sealing layer, zone base etc. Piezo-electric device with rubber case, to be installed on choice, can be secured to said inner sealing layer and tire outer surface. Piezo-electric devices can be made integral with protective support to run at higher speed when tire loses air pressure. In another version piezo-electric devices can also be made integral with non-pneumatic tire with structural support as, for example tire comprising reinforced circular rim, multiple sheet spokes running across reinforced circular rim and radially inside from it. It includes also mounting rim on inner end of mounting spokes and tread section arranged on circular rim.

EFFECT: tire with built-in electronic components with no stage batteries intended for running tire checks.
