A TORSIONAL VIBRATION DAMPER HUB FOR A VEHICLE CLUTCH

摘要

A torsional vibration damper hub for a vehicle clutch comprising a first row of springs (814a) extending substantially in the clutch rotating direction and disposed in openings formed in first inner annular plate and first pair of outer annular plates; second row of springs (814b) extending substantially in the clutch rotating direction and disposed in openings formed in said second inner annular plate and said second pair of outer annular plates; said first and second row of said springs being arranged on same radius from centre of rotation of said clutch; the springs (814a) in said first row of springs arranged in one first axial level are axially overlapping the springs (814b) in said second row of springs arranged in a second axial level with the purpose to decrease a total axial length of said clutch. In an alternative embodiment the damper hub is substantially identical to a dual damper hub (412a, 412b) in conventional twin- plate clutches (401) .
