ARCHITECTURE DE ROUE D'INERTIE POUR LE STOCKAGE D'ENERGIE

摘要

The invention relates to an inertia wheel comprising a storage ring (1) and a hub (2) connecting the storage ring (1) to a rotation shaft (3) of the wheel, said hub (2) comprising a central part forming a hub body (2a) for connecting to the shaft (3), a peripheral part forming a rim (2c) for connecting to the storage ring and an intermediate part formed by a disk (2b) between the hub body and the rim. The inertia wheel is characterised in that the hub is made from a composite material and includes a module having a stiffness that decreases from the hub body to the rim. The invention also relates to the method for producing such an inertia wheel.
