An impeller for a torque converter is provided. The impeller includes an impeller shell including an inner circumference, an outer circumference and a radial extension extending radially outward from the inner circumference. The radial extension includes an axially extending groove formed therein. The impeller also includes an impeller hub welded to the impeller shell by a weld. The weld is radially inside of the axially extending groove. A method of forming an impeller for a torque converter is also provided.

Torque converter impeller including impeller shell having thinned section

A torque converter, including an axis of rotation, a cover arranged to receive torque, an impeller including an impeller shell non-rotatably connected to the cover and, at least one impeller blade fixedly connected to the impeller shell, a turbine including a turbine shell and at least one turbine blade fixedly connected to the turbine shell, a stator axially disposed between the impeller and turbine shells and including at least one stator blade and a first core ring fixedly secured to the at least one impeller blade and, including at least one first flat annular surface facing the at least one turbine blade or a second core ring fixedly secured to the at least one turbine blade and, including at least one second flat annular surface facing the at least one impeller blade.

Torque converter with a flat annular core ring

A thrust assembly for a torque converter is provided. The thrust assembly includes a drivable mating component and a thrust washer connected to the drivable mating components. The thrust washer includes a thrust surface on a first axial side thereof and at least two axial contact surfaces on a second axial side thereof opposite the first axial side. The at least two axial contact surfaces include a first axial contact surface at a first axial distance from the thrust surface and a second axial contact surface at a second axial distance from the thrust surface. The first and second axial contact surfaces are configured for alternatively contacting the axial contact surface of the drivable mating component so as to vary an effective height of the thrust surface with respect to the drivable mating component.

Torque converter thrust assembly having variable effective thickness

A blade for a torque converter, including: a body with first and second blade side surfaces and a blade edge surface connecting the first and second blade side surfaces; and a tab extending from the blade edge surface and arranged for insertion through an opening in a core ring for the torque converter. The tab includes: a distal end furthest from the blade edge surface; first and second tab edge surfaces in communication with the distal end; and first and second indentations in the first and second tab edge surfaces, respectively, between the distal end and the blade edge surface. The core ring forms at least respective portions of respective inner circumferences for a turbine and pump for the torque converter. After insertion through the opening, the tab is arranged to be bent along a line connecting the indentations so that a portion of the tab engages the core ring.

Torque converter blade tab undercuts

A blade family for torque converters with a first blade having a first shape and flow guiding surface and a second blade having a second shape and flow guiding surface. The first surface is different from the second surface and the first shape is the same as a portion of the second shape, or the second shape is the same as a portion of the second shape. In an example embodiment of the invention, at least one of the first or second blades includes holes or slots. In an example embodiment of the invention, the first blade includes more material than the second blade. The first and second blades may have respective mounting tabs, with the second blade having fewer mounting tabs than the first blade. Other example aspects of the present invention broadly comprise a torque converter with a plurality of first and/or second blades from the blade family.
