Abstract
A torque converter is provided. The torque converter includes a front cover and an impeller shell including an axially extending section fixed to the front cover. The impeller shell includes a connector on the axially extending section. The connector is configured for connecting to an engine drive plate assembly. A method for forming a torque converter is also provided. The method includes providing connector on an axially extending section of an impeller shell, the connector being configured for connecting to an engine drive plate assembly; and fixing the axially extending section to a front cover.
Claims17
A torque converter comprising:
- a front cover including an axially extending section;
- and
- an impeller shell including an axially extending section fixed to the front cover, the impeller shell including a connector on the axially extending section, the connector being configured for connecting to an engine drive plate assembly, the axially extending section of the front cover including a rim configured for facing toward the engine drive plate assembly,
- wherein the axially extending section of the front cover is welded onto an inner circumferential surface of the axially extending section of the impeller shell,
- wherein the front cover includes a tapered section tapering axially away from the engine drive plate assembly, the axially extending section of the front cover extending axially away from an outer end of the tapered section toward the engine drive plate assembly.
A method for forming a torque converter comprising:
- providing a connector on an axially extending section of an impeller shell, the connector being configured for connecting to an engine drive plate assembly;
- and
- welding an inner circumferential surface of the axially extending section of the impeller shell to an axially extending section of a front cover, the front cover including a tapered section tapering axially away from the engine drive plate assembly, the axially extending section of the front cover extending axially away from an outer end of the tapered section toward the engine drive plate assembly.
A torque converter comprising:
- a front cover;
- and
- an impeller shell including an axially extending section fixed to the front cover, the impeller shell including a connector on the axially extending section, the connector being configured for connecting to an engine drive plate assembly,
- wherein the connector is formed integrally with the axially extending section,
- wherein the connector is a folded portion extending radially away from the axially extending section, and
- wherein the folded portion includes a first radially extending section extending radially outward from the axially extending section and a second radially extending section extending radially inward from a radially outer end of the first radially extending section, the folded portion including a plurality of holes passing axially through first and second radially extending section, each of the holes being configured for receiving one of a plurality of fasteners of the engine drive plate assembly.
