Minimum complexity vibration damper
This patent describes a vibration damper assembly for a torque converter lockup clutch, friction clutch or torsional coupling, comprising a pressure plate, a reactor plate, a generally cylindrical hub barrel operatively connected to a transmission input shaft, the reactor plate directly connected to the hub barrel and having a pair of outwardly curved arcuate channels extending for approximately 180/sup 0/ acting as spring pockets and separated by a pair of diametrically opposed inwardly offset drive straps. The pressure plate is generally flat and provided with a pair of diametrically opposed inwardly offset substantially triangular spring abutments 90/sup 0/ removed from the drive straps and projecting into the channels. Two pairs of oppositely disposed damper springs, the pressure plate and reactor plate form spring pockets enclosing the damper springs positioned between the spring abutments and drive straps. The drive straps and spring abutments provide reactions surfaces contacting the ends of the springs.
