20090159390 | Friction one-way clutch - The present invention is a friction one-way clutch that may be used with automotive components such as a stator in a torque converter. The clutch includes a circular outer race attached to the stator, a flat wedge ring having at least one wedge and fit into an inner perimeter of the outer race to form an interference fit with the outer race. The interference fit is formed by a wedge angle between the inner perimeter of the outer race and the outer perimeter of the wedge ring. An inner race with at least part of its outer edge formed by one or more tapered ramps fits into the inner circumference of the wedge ring. The inner race is attached by splines to a stator shaft.

The one-way clutch mechanical system includes an inner element and an outer element, which are movable relative to one another in rotation around a central axis (X1) and delimits an annular housing between them. The system further includes a one-way clutch device positioned in the annular housing, a member for damping a relative rotational movement between the inner and outer elements and for transmitting torque to the one-way clutch device, which is also positioned in that annular housing. The damping and torque transmission member is axially offset relative to the one-way clutch device, along the central axis (X1). | 04-09-2015 |
20150096861 | ONE-WAY MECHANICAL CLUTCH SYSTEM AND ALTERNATOR COMPRISING SUCH A SYSTEM - The invention relates to a one-way clutch mechanical system for a pulley-assembly of a motor vehicle alternator, having an inner element, an outer element rotatably movable relative to one another around a central axis and delimiting an annular housing between them. A one-way clutch device positioned in the annular housing and a member damping a relative rotational movement between the inner and outer elements and elements transmitting torque to the clutch device is provided. A ring rotatably secured to a first element and adjacent, along the central axis, to a damping and torque transmission member, is provided with first means for activating the member to transmit torque. A sleeve belonging to the one-way clutch device is provided with second means for activating the damping and torque transmitting member. The one-way clutch device has cams that bear against the sleeve and the second activation means has at least one raised portion. | 04-09-2015 |
20150345574 | RATCHET TYPE ONE-WAY CLUTCH AND ARRANGEMENT OF PAWL MEMBER THEREIN - A ratchet type one-way clutch includes an outer race having a pocket, an inner race having a notch, a pawl member housed in the pocket to transmit torque between the inner race and the outer race, and having a tip portion engaging with the notch and a circular portion; and a spring urging the pawl member to the inner race is provided. A central angle of the circular portion is 180 degrees or greater. An angle between a segment between both ends of an opening of the circular arc portion and a segment between the circular portion of the pawl member and a contact point at which the tip portion engages with the notch is greater than 90 degrees, and an angle between the spring and a segment between the center of the circular portion and a center of the ratchet type one-way clutch is greater than 45 degrees. | 12-03-2015 |
20160017937 | ROCKER ONE-WAY CLUTCH - 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. | 01-21-2016 |
