Abstract
In combination with vehicle wheels a means for performing reduction of effective vehicle bearing weight thereby mitigating rolling resistance thereof enhancing energy efficiency. Attachment to be radially fixed on and around a vehicle wheel and configured to extend beyond the periphery of the wheel in a prolapse condition not common to wheel art. The attachment shall be displaceable and capable of energy storage and release sequaciously. Operation shall be via the nutation of the extended attachment with each nutating cycle bifurcated by the vehicle bearing weight area thereof allowing the bearing weight to be transferred to the displaceable attachments dynamically. The effective bearing weight of the vehicle is reduced and thereof deformations to the vehicle wheel and roadway are mitigated. Reduction of the deformations mitigate nonproductive energy transfer from the vehicle wheel and roadway structure. Wayward to the leeward force displacements are conserved in accordance to the principle of energy conservation. Means of energy efficiency is thus provided.
