Abstract

A torque converter includes a torus with an impeller and a turbine having respective shells, a cover shell, and a first damper plate. The impeller shell has a radial wall disposed radially outside of the torus and the turbine shell has a radial wall arranged for frictionally engaging the impeller shell radial wall. The cover shell has a radial wall and the first damper plate has a radial wall for transmitting a turbine shell thrust force to the cover shell radial wall. In an example embodiment, the torque converter includes a friction material ring fixedly attached to the turbine shell radial wall or the impeller shell radial wall. In some example embodiments, the torque converter includes a friction material ring fixedly attached to the cover shell radial wall or the first damper plate radial wall.

First claim

We claim:

1. A torque converter comprising:
a torus including an impeller and a turbine;
an impeller shell including an impeller shell radial wall disposed radially outside of the torus;
a turbine shell including a turbine shell radial wall arranged for frictionally engaging the impeller shell radial wall;
a cover shell fixed to the impeller shell and including a cover shell radial wall; and,
a first damper plate including a first damper plate radial wall for transmitting…
