TORSIONAL ISOLATOR FOR TORQUE CONVERTER LOCK-UP MECHANISM ABSTRACT An improved damper is provided for minimizing the transmittal of engine generated torsional vibrations through a transmission employing a hydrokinetic torque converter when the torque converter is operated in a locked up mode wherein the turbine and impeller thereof are mechanically interconnected. The damper includes a drive ring drivingly engageable with the impeller of the torque converter and configured to define an annular channel having a plurality of spring pockets formed therein, a plurality of springs received in the pockets, and a driven ring which may be secured for rotation with the turbine of the torque converter and having a plurality of drive lugs for engaging the springs. The drive ring pockets further include spring seats configured to urge the springs in a direction opposing centrifugal force and the driven ring lugs are formed to facilitate snap fit of the springs into engagement therewith.
