Abstract
A flywheel has first and second axially-spaced, coaxial flyrings. At least one resilient element connects the flyrings for permitting relative rotational displacement therebetween. A damping device also connects the flyrings operatively in parallel with the resilient element for impeding the relative rotational displacement of the flyrings permitted thereby after some, lost relative rotational displacement up to about .+-.30.degree..
Claims12
A flywheel, comprising:
- first and second axially-spaced, coaxial flyrings;
- at least one resilient element, connected between said first and second flyrings, permitting relative rotational displacement therebetween during small relative rotational displacements of free travel up to about .+-.30.degree.;
- damping means, connected between said first and second flyrings and operatively in parallel with said resilient element, for impeding the relative rotational displacement of the flyrings after said free travel;
- whereby the flyrings interact with respect to each other during said free travel only through the resilient element, and interact through the damping means in case of bigger displacements.
