A method of manufacturing a variable pitch torque converter stator includes positioning a framework, including an outer ring, a plurality of blades, a plurality of pivot members, and a plurality of actuation members, so the pivot members are seated in a stator body and the actuation members are coupled to a stator piston, with the pivot and actuation members being non-rotatably coupled to opposite ends of corresponding blades. The method includes removing the outer ring from the framework.

A blade assembly for a torque converter includes a shell defining an inner surface and a plurality of blades arranged around the inner surface of the shell. The plurality of blades each include a curved portion contacting the inner surface. The plurality of blades each further include a curved region axially spaced from the respective curved portion. The plurality of blades each further include an end extending from the respective curved portion to the respective curved region. Each end includes a notch arranged radially closer to the respective curved region than to the respective curved portion.

A hydrodynamic coupling arrangement has a housing connected to pressure medium lines for conducting pressure medium into or out of a pressure space sealed by a piston of a clutch device relative to a toroidal space of a hydrodynamic circuit provided in the housing. A rotatable area is provided for axially displaceably receiving a radially inner piston hub of the piston of the clutch device, and at least one through-opening which is rotatable relative to the housing is provided in a through-opening area for producing at least one flow connection between at least one pressure medium line and the pressure space. The receiving area and the through-opening area are in rotational communication with a retarding device influencing a flow of pressure medium in the pressure space, this flow of pressure medium arriving in the pressure space after passing through the through-opening area.

A torque converter includes an impeller, a turbine, and a variable-pitch stator adjacent the turbine. The stator includes a hub and blades circumferentially arranged around the hub and pivotal between open and closed positions. The stator further includes an annular carrier connected to the blades and configured to rotate relative to the hub in response to pivoting of the blades, and a thrust disk engageable with the carrier to inhibit rotation of the carrier relative to the hub to maintain positions of the blades.

A hybrid module configured for arrangement in a torque path upstream from a transmission and downstream from an internal combustion engine includes a drive unit including an electric motor and a housing, a torque converter connected to the electric motor and at least one baffle blade extending axially from the housing radially outside of the electric motor and the torque converter.

A torque converter stator has interchangeable blades and has a body member with a central hub and an annular wall. Dovetail openings are located on an outer surface of the annular wall. Each blade has a dovetail pin that is removably received within a respective one of the dovetail openings. A cover plate is removably attached to the body member in order to secure the blades in place within their respective dovetail openings. A heated duct ring is positioned over the outer ends of the blades and allowed to heat shrink into contact with these ends as the duct ring cools and shrinks, thereby securing the duct ring to the remainder of the stator.
