Flywheel assembly with vibration dampening mechanism

A flywheel assembly (1) comprising:

• a first flywheel (2) having an annular space (A) partially confined by said first flywheel (2);
• a driven plate (15) arranged to rotate freely relative to said first flywheel (2) within said annular space (A), said driven plate (15) having a plurality of radially extending protrusions (15c);
• an elastic coupling mechanism (8) that elastically connects said first flywheel (2) and said driven plate (15) circumferentially;
• a viscous dampening mechanism (9) disposed within said annular space (A) having a fluid filled chamber (B) arranged between said first flywheel (2) and said driven plate (15) that includes a plurality of openings through which said plurality of protrusions (15c) extend;
• a choke formed within said fluid filled chamber (A) allowing the passage of fluid in response to rotary displacement of said first flywheel (2) and said driven plate (15) relative to each other;
• a plurality of radially spaced apart seal members (23) disposed within said fluid filled chamber (B) and radially adjacent to an outer radial surface of said driven plate (15).

• a plurality of stoppers (21) that divide the inside of said fluid filled chamber (B) into a plurality of arc-shaped chambers;
• a slider (22) arranged inside each of said arc-shaped chamber;
• a choke that allows for the passage of fluid inside said fluid filled chamber (B) in response to movement of said sliders (22) relative to said first flywheel (2);
• and
• a plurality of radially spaced apart seal members (23) disposed within said fluid filled chamber (B) and radially adjacent to an outer radial surface of said driven plate (15);
• wherein one of each of said seal members (23) extends circumferentially between adjacent ones of said sliders (22) and disposed radially inward from said stoppers (21).
