Abstract
A torque converter is provided. The torque converter includes an impeller; a turbine axially movable toward and away from the impeller; and a damper coupled to the turbine, the damper including an elastic element forcing the turbine against the impeller in an equal pressure condition. A method of forming a torque converter is also provided. The method includes forming a damper to include an elastic element; providing the damper inside a front cover so the damper contacts the front cover; and providing axially movable turbine between the damper and an impeller such that the elastic element forces the turbine to engage an impeller in an equal pressure condition.
Claims19
A torque converter comprising:
- an impeller;
- a turbine axially movable toward and away from the impeller;
- a damper coupled to the turbine, the damper including an elastic element forcing the turbine against the impeller in an equal pressure condition in which a fluid pressure on a first side of the turbine equals a fluid pressure on a second side of the turbine;
- and
- a front cover for connecting to an engine, the damper including a thrust surface for slidingly engaging the front cover.
A torque converter comprising:
- an impeller;
- a turbine axially movable toward and away from the impeller;
- and
- a damper coupled to the turbine, the damper including an elastic element forcing the turbine against the impeller in an equal pressure condition in which a fluid pressure on a first side of the turbine equals a fluid pressure on a second side of the turbine,
- wherein the turbine includes a turbine shell having a friction surface, the friction surface contacting the impeller in the equal pressure condition.
