Abstract:
A thrust washer for a torque converter is provided. The thrust washer includes an inner circumferential surface, an outer circumferential surface and a first axial surface extending from the inner circumferential surface to the outer circumferential surface. The axial surface includes a plurality of arcuate sections and a plurality of grooves circumferentially between the arcuate sections. Each of the arcuate sections includes an arcuate axial surface including a first section, a second section and a third section. The first and third sections extend circumferentially away from the second section in opposite directions and extend axially inward from the second section. A torque converter and a method for forming at least one torque converter are also provided.
