Abstract
A control assembly (10) for controlling the actuation of two clutch packs (50, 52) includes a motor (12) for driving an annular gear wheel (24). Radial pins (30) project from the gear wheel to engage concentric pistons (34, 36) arranged for linear movement relative to one another along the axis of rotation of the gear wheel. Each piston includes slots (40) which define cam surfaces for engagement by the drive pins. Rotation of the gear wheel in first direction causes the pins to drive against cam surfaces on the inner piston, to drive the inner piston towards the inner clutch. Rotation of the gear wheel in the opposite direction causes the pins to drive against cam surfaces on the outer piston, to drive the outer piston towards the outer clutch.
