Abstract
A centrifugally balanced hydraulic clutch assembly includes a hydraulic chamber configured to rotate about an axis of rotation and a clutch piston that is partially situated within the hydraulic chamber and defines both an apply volume and a release volume. The clutch piston includes an inner surface and an outer surface, where a portion of the outer surface faces the apply volume and defines an apply area, and a portion of the inner surface faces the release volume and defines a release area. Additionally each portion of the apply area is provided at a respective distance from the axis of rotation, and, for each portion of the apply area, there is a corresponding portion of the release area provided at the same radial distance.
