Abstract
An inertia wheel including a storage ring and a hub connecting the storage ring to a rotation shaft of the wheel, the hub including a central part forming a hub body for connecting to the shaft, a peripheral part forming a rim for connecting to the storage ring and an intermediate part formed by a disk between the hub body and the rim. The hub is made from a composite material and includes a module having a stiffness that decreases from the hub body to the rim. A method for producing such an inertia wheel is also provided.
Claims23
An inertia wheel comprising:
- a storage ring and a hub connecting the storage ring to a rotation shaft of the wheel, wherein the hub, including a central portion forming a hub body connected to the shaft, a peripheral portion forming a rim connected to the storage ring and an intermediate part consisting of a disk between the hub body and the rim, is made from composite material and has a stiffness modulus decreasing from the hub body to the rim.
