Flywheel for driving rail or road vehicle - has stub shafts with intermediate hollow conical components coupled to flywheel at larger ends

摘要

The flywheel is coupled on both sides via an intermediate component to a stub shaft, the component having an annular portion by which it is secured to the flywheel. The component (11) is a half-open cylindrical or conical body, its open end with the largest diameter being secured to the flywheel (10), while the other end has a stub shaft (12, 13). The component has a shape and material where it is fixed to the flywheel to give it a radial stiffness. The component can have one or more conical portions and can be of anisotropic and typically fibre-reinforced composite material.
