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.
