Abstract
A torque converter with a casing, a turbine, and a piston having a first friction surface located at a radially outer portion of the piston, and a first drive ring having second and third friction surfaces. The piston is displaceable to engage the first and second friction surfaces. The torque converter also includes a second drive ring having fourth and fifth friction surfaces. The first drive ring is displaceable to engage the third and fourth friction surfaces. The second drive ring is driveably connected to the piston and to an elastic member of a damper. The torque converter includes a sixth friction surface for the casing. The second drive ring is displaceable to engage the fifth and sixth friction surfaces, the first drive ring and the casing are nonreleasably connected, and the first drive ring is axially displaceable with respect to the casing.
