  • Spiral spring of a torsional damper
    Patent number: 5234376
    Abstract: A torsion isolator assembly (30) for reducing driveline torsionals includes a vane damper (36) having valving (40d,40e) for regulating the damping factor of the damper, spiral springs (32,34 or 82,84), and cam surfaces (44d,44c) which engage the ends of the spiral springs (32,34 or 82,84).; The spiral springs (32,34 or 82,84) have a lesser radial spacing between the outer convolutions as compared to the radial spacing between the inner convolutions.

  • Mounting for rotating spiral spring
    Patent number: 5226514
    Abstract: A torsion isolator assembly (30) for reducing driveline torsionals includes a vane damper (36) including improved valving (40d,40e) for increasing the damping factor of the damper, improved spiral springs (32,34 or 80,82) for reducing spring stress primarily due to centrifugal forces, and cam surfaces (44d,44c) for further reducing spring stress due to centrifugal forces.
