Abstract

A rocker one-way clutch includes a stator housing, an inner race, and a strut. The stator housing has a strut pocket and a plurality of stator blades. The inner race has a first angled contact face. The strut is disposed in the strut pocket and has a second angled contact face arranged to contact the first angled contact face. In an example embodiment, an angle between a line passing from the contact face to a rocker pivot center and a line parallel to the contact face is acute. In an example embodiment, the acute angle is approximately 10 degrees.

First claim

What we claim is:

1 . A rocker one-way clutch comprising:
a stator housing including a strut pocket and a plurality of stator blades; an inner race with a first angled contact face; and, a strut disposed in the strut pocket and including a second angled contact face arranged to contact the first angled contact face.

2 . The rocker one-way clutch of claim 1 wherein an angle between a line passing from the contact face to a rocker pivot center and a line parallel to the contact face is acute.

3 . The rocker one-way clutch of claim 2 wherein the acute angle is approximately 10 degrees.

4 . A rocker element for a one-way clutch comprising:
a cylindrical portion; a connector portion extending radially from the cylindrical portion; and, an end segment including a distal face disposed at an acute angle to a plane orthogonal to the connector portion.

5 . The rocker element of claim 4 wherein a thickness of the end segment is greater than a thickness of the connector portion.

6 . The rocker element of claim 4 wherein the connector portion and the end segment combine to form a pocket for receiving a spring element.

7 . A one-way clutch assembly comprising:
the rocker element of claim 4 ; and, a tubular inner race including a plurality of radial extensions, each radial extension including:
an edge extending radially outward at an acute angle to a radial line passing through the edge and a center of the inner race and arranged for contacting the rocker element end segment distal face; and,
an outer ramped portion including first and second non-coplanar ramped surfaces.

8 . The one-way clutch assembly of claim 7 wherein the inner race further comprises an inner spline.

9 . A stator for a torque converter comprising:
the one-way clutch assembly of claim 7 ; a stator housing including a first cylindrical pocket and a second pocket; and, a spring element disposed in the second pocket and in contact with the rocker element;
wherein the rocker element is disposed in the first cylindrical pocket and is arranged to contact the inner race.

10 . The stator of claim 9 wherein the rocker element is arranged to contact the inner race edge and at least one of the ramped surfaces.
