Abstract
A torque converter, including: a cover arranged to receive torque; an impeller including an impeller shell non-rotatably connected to the cover and at least one impeller blade connected to the impeller shell; a turbine including a turbine shell, at least one turbine blade connected to the turbine shell, and a heat treated portion; and a torsional vibration damper including: a cover plate arranged to receive torque from the cover or the turbine; and a spring. The spring is engaged with the cover plate and is arranged to contact the heat treated portion when the spring is compressed.
Claims18
A torque converter, comprising:
- a cover arranged to receive torque;
- an impeller including:
- an impeller shell non-rotatably connected to the cover;
- and,
- at least one impeller blade connected to the impeller shell;
- a turbine including:
- a turbine shell;
- at least one turbine blade connected to the turbine shell;
- and,
- a heat treated portion;
- and,
- a torsional vibration damper including:
- a first cover plate arranged to receive torque from the cover or the turbine;
- and,
- a spring:
- engaged with the first cover plate;
- and,
- arranged to contact the heat treated portion when the spring is compressed, wherein:
- the turbine shell is formed of a first piece of material;
- and,
- the heat treated portion is:
- formed of a second piece of material, different from the first piece of material;
- and,
- non-rotatably connected to the turbine shell.
A torque converter, comprising:
- a cover arranged to receive torque;
- an impeller including:
- an impeller shell non-rotatably connected to the cover;
- and,
- at least one impeller blade connected to the impeller shell;
- a turbine including:
- a turbine shell including a heat treated portion;
- and,
- at least one turbine blade connected to the turbine shell;

- a first cover plate arranged to receive torque from the cover or the turbine;
- and,
- a spring:
- engaged with the first cover plate;
- and,
- contacting the heat treated portion of the turbine shell when the spring is not compressed, wherein the turbine shell includes:
- a first segment including the heat treated portion;
- and,
- a second segment:
- separately formed from the first segment;
- fixedly secured to the first segment and,
- located radially outward of the first segment.
