Abstract
A torque converter, which may be found in an automotive transmission, is provided. In some examples, the torque converter includes a shell that extends about an axis of rotation, a core that extends about the axis of rotation, and a plurality of curved blades that extend contactedly from the shell to the core. At least one blade of the plurality of curved blades may include a non-ruled surface. The at least one blade of the plurality of curved blades may narrow as it extends from the shell to the core.
Claims22
A torque converter, the torque converter comprising:
- a shell extending about an axis of rotation;
- a core extending about the axis of rotation;
- and
- a plurality of curved blades extending contactedly from the shell to the core, wherein at least one blade of the plurality of curved blades comprises a non-ruled surface curving between the shell and the core, and
- wherein the at least one blade of the plurality of curved blades narrows as it extends from the shell to the core.
A torque converter, the torque converter comprising:
- a shell extending about an axis of rotation;
- a core extending about the axis of rotation;
- and
- a plurality of curved blades configured for use with an incompressible fluid, wherein the plurality of blades extend between the shell and the core, and wherein at least one blade of the plurality of curved blades comprises:
- a first point at which the at least one blade intersects the shell, the first point being coincident to a line extending orthogonally through the axis of rotation, and
- a second point at which the at least one blade intersect the core, the second point also being coincident to the line extending through the axis of rotation,
- wherein the at least one of the plurality of curved blades comprises a non-ruled surface curving between the shell and the core.
A torque converter, the torque converter comprising:
- a shell extending about an axis of rotation;
- a core extending about the axis of rotation;
- a plurality of blades curving contactedly from the shell to the core;
- a turbine extending about the axis of rotation, and around the plurality of blades;
- a first radius defined between the axis of rotation and a point along the turbine;
- and
- a second radius defined between the axis of rotation and a point along the shell opposite the point along the turbine, wherein the second radius extends coaxially along the first radius, wherein the first radius subtracted by the second radius defines a height of the torque converter, and wherein a ratio of a width of the torque converter, as measured along the axis of rotation, to the height of the torque converter is about 0.75, thereby defining an oblong profile of the torque converter.
