Abstract
The present disclosure provides a rotational spring dampener including a core having an opening therethrough, a first solid component having a first set of bosses, a second solid component having a second set of bosses, and a tensile member positioned between the first solid component and the second solid component. The tensile member is composed of a solid silicon polymer.
Claims20
A rotational spring dampener, comprising:
- a core comprising an opening therethrough;
- a first solid component comprising a first set of bosses;
- a second solid component comprising a second set of bosses;
- and
- a tensile member positioned between the first solid component and the second solid component, and
- wherein the tensile member comprises a solid silicon polymer.
A rotational spring dampener assembly, comprising:
- a cap including a cap opening;
- a base plate including a base plate opening;
- and
- a dampener, the dampener placed between the cap and the base plate, the dampener comprising:
- a first disk and a second disk disposed at a first end and a second end of a compression limiter, respectively;
- a tensile member extending between the first disk and the second disk, the tensile member wrapping around the compression limiter about a longitudinal axis;
- and
- a hole,
- wherein the cap opening, the hole, and the base plate opening are concentric about a longitudinal axis.
The rotational spring dampener assembly of claim 21, wherein the base plate includes a plurality of securing openings and the second disk including a plurality of securing members protruding outwardly from the second disk, wherein the plurality of securing members are received by the plurality of securing openings.
A rotational spring dampener assembly, comprising:
- a first solid component, the first solid component including a plurality of solid modular subcomponents, the solid modular components including a plurality of first bosses and a central aperture;
- a second solid component, the second solid component including a body and a plurality of second bosses extending outwardly from an outer surface of the body;
- a tensile member, the tensile member including a plurality of voids disposed between a plurality of bands;
- and
- at least one longitudinal cap disposed at an end of the tensile member,
- wherein the plurality of second bosses is received by the plurality of voids of the tensile member to create a first sub assembly, and
- wherein the first sub assembly is inserted through the central aperture of the first solid component.
The rotational spring dampener assembly of claim 22, wherein the plurality of voids receives at least one of the plurality of first bosses.
