Torque converter with turbine mass absorber

A piston plate assembly for a torque converter comprising:

• a piston plate including:
• first and second radial surfaces and a thickness therebetween;
• an opening forming an inner circumferential surface, having a width at most equal to the thickness, at a distance from an axis of rotation for the piston plate;
• and,
• a chamfer surface connecting the inner circumferential surface with the first radial surface;
• and,
• a bushing including an axial portion in contact with the inner circumferential surface and a radial portion extending from a first end of the axial portion and in contact with the radial surface, wherein:
• an outside diameter of the axial portion at a second end of the axial portion, opposite the first end, is less than the distance;
• and
• the outside diameter of the axial portion increases from the second end to the first end.

A torque converter comprising:

• an axis of rotation;
• a cover;
• a turbine including a turbine shell;
• an impeller including an impeller shell;
• a piston plate comprising:
• first and second radial surfaces and a thickness therebetween;
• an opening forming an inner circumferential surface, having a width at most equal to the thickness, at a distance from the axis of rotation;
• and,
• a chamfer surface connecting the inner circumferential surface with the first radial surface;
• a bushing installed in the aperture and including a radius portion proximate the chamfer portion, wherein the bushing is arranged to seal the piston directly to a transmission input shaft and the radius portion is arranged to ease assembly of the bushing onto the input shaft;
• and;
• a damper assembly comprising:
• an output hub;
• and,
• a flange arranged to spline directly to the transmission input shaft.
