Abstract
The present invention is a double path torsion isolator for use in conjunction with a torque converter. Each of the two vibration paths includes a flange with a spring connection to each of the torque converter cover and an output connection attached to the transmission shaft. The torque converter turbine is connected to one of the flanges to provide a different frequency to the associated vibration path. When the lockup clutch is engaged, the engine vibration is divided along the two vibration paths toward the common output connection. The vibration frequency of the paths are adjusted so that the frequencies of the two paths are 180° out of phase at the output connection providing a vibration cancellation effect to the output connection.
