Abstract
A method of manufactore of, and apparatus for, a torque converter assembly having an improved reactor assembly. A torque converter is disclosed having a stator which has improved and simplified casting and machining requirements. A stator hub is provided having a cylindrical bore substantially coaxial with the axis of the transmission shaft to which the torque converter is mounted. An overrunning clutch and thrust bearing cartridge assembly is provided to be fitted into the stator hub bore. The overrunning clutch provides improved lubrication on both sides of the clutch engaging element surfaces, either rollers or sprags, between the inner and outer rings which form the clutch races. Wear surfaces within the clutch assembly are stamped steel instead of aluminum. Clutch load is increased by increasing the roller or sprag dimensions in the direction of the stator axis, while maintaining the same stator hub width. Thrust bearings are mounted to the outside of the overrunning clutch.
