  • Stator side plate for a torque converter
    Patent number: 7802668
    Abstract: The present invention broadly comprises a stamped side plate for a torque converter stator, including: an annular segment having an inner circumferential surface and a top surface and at least one protrusion extending radially inward beyond the inner circumferential surface. The at least one protrusion comprises a race retaining surface substantially parallel to the top surface. The inner circumferential surface and the race retaining surface are arranged to center and retain an inner race for the stator, respectively. The annular segment also includes at least one annular protrusion extending from the top surface and including a centering surface substantially orthogonal to the top surface. The centering surface is arranged to center a bearing for the stator. The at least one annular protrusion is proximate the inner circumferential surface or an outer edge for the annular segment.

  • Torque converter
    Publication number: 20040172936
    Abstract: A method and a device are described for influencing the flow in a torque converter. The peripheral velocity of the fluid on its way to the open end of the transmission input shaft is made to approach the respective peripheral velocity of the converter housing.
