First Claim
Patent Images
1. A flywheel system comprising:
- a substantially cylindrical housing comprising a wall portion;
a substantially cylindrical liner positioned within the housing;
a flywheel rotatably disposed within the liner; and
, means contacting the wall portion and the liner for restraining the liner in relation to the housing when the liner is subjected to a torque below a predetermined threshold and releasing the liner when the liner is subjected to a torque substantially equal or greater than the predetermined threshold.

Abstract
The invention provides a flywheel system with energy-absorbing housing. The system provides a novel liner and restraint ribs which serve to de-energize debris particles resulting from the catastrophic failure of a flywheel. Also provided are energy-absorbing housing systems comprising a rotatable liner, one or more restraint ribs, and a fluid film bearing to control and dissipate the energy from the failure of a rotating mass.
