Wheel generator having a coupling system

A converter for obtaining electrical energy in a rolling wheel of a vehicle from a deformation of a wheel tire due to contact with a road surface, comprising

• a) at least four lever elements, which at their first end are rotatably housed, and at their second end are configured to come into contact with an inside of the wheel tire via at least one contact element such that the deformation of the wheel tire due to contact with the road surface causes a rotational movement of a lever element of the at least four lever elements,
• b) a mechanical coupling element system configured for transferring a force occurring due to the rotational movement of the at least four lever elements, and
• c) at least one electrical generator configured to convert the force transferred by the mechanical coupling element system into electrical energy,
• wherein the at least four lever elements are each pivotally mounted at their first end by means of a shaft and the shaft is configured to transmit the force of the rotational movement,
• wherein the mechanical coupling element system per shaft of each lever element has at least two coupling elements, which are each arranged to transmit the force of the rotational movement to the shaft of the adjacent lever element or to an intermediate shaft,
• wherein at least one planetary gear system is present, which is arranged to transmit the rotational movement of a shaft of a lever element or an intermediate shaft to the at least one electrical generator, and
• wherein a sum (A+B) of a distance A of a fulcrum N of a given lever element from a wheel center M and a distance B of the fulcrum N from a contact point K of a contact element with the inside of the wheel tire, in a case of a plurality of contact elements per lever element the contact point with a greatest distance from the fulcrum N, relative to a radius of the inside of the wheel tire R ((A+B)/R)) is in a range from 102% to 110%.
