The invention broadly comprises a torque converter including: a core ring; a turbine blade connected to the ring and having a perimeter with a segment facing an outer surface of the ring and disposed proximate the outer surface; and joining material fixedly connecting less than the entirety of the segment to the outer surface. The segment is fixedly connected to reduce resonance in the turbine. In some aspects, the ring includes an inner surface oppositely disposed from the outer surface and an open path between the surfaces. The present invention broadly comprises a notched turbine blade and a core ring with a discontinuity in an outer surface arranged to block capillary action for flowable joining material disposed in an interface between a turbine blade installed on the ring and the outer surface. The invention also broadly comprises a method for controlling resonance of a turbine in a torque converter.

Torque converter with brazed turbine

The present invention broadly comprises a stator for a torque converter with first and second plates. The first plate is connected to a rim for the stator and includes at least one first opening. The second plate is connected to the a hub for the stator and includes at least one first protrusion lockingly engageable with the at least one first opening. The first plate is rotatable about an axis for the hub and the at least one first protrusion and the at least one first opening are lockingly engageable when the first plate is rotated in a first direction with respect to the axis. The at least one first protrusion and the at least one first opening are slidingly engageable when the first plate is rotated in a second direction opposite the first direction.

Axially engaging and disengaging one-way clutch and a stator having an axially engaging and disengaging one-way clutch

A torque converter with torus shape that is sheared such that imagined axial sections through the torus shape, starting from the inner stator passage diameter, are shifted increasingly axially in one direction as the effective radius increases.
