Abstract
A torque converter comprising: first and second cover plates arranged to receive torque; a flange; a turbine shell independently rotatable relative to the flange; at least one resilient element, at least partially disposed axially between the first and second cover plates, for transmitting a torque force between the flange and the first and second cover plates; a first axial gap, disposed between the flange and the first cover plate, having a first width; a second axial gap, disposed between the flange and the second cover plate, having a second width; one of the first cover plate or the second cover plate having at least one ramp protruding in an axial direction toward the flange, the ramp rotatably engageable with the flange for urging the flange axially in a direction toward the cover, and for transmitting an axial force for urging a clutch to engage.
