  • Patent number: 10247261
    Abstract: An actuation device having a piston is used to actuate a mechanical or friction clutch by means of differential pressure. Two sides of a piston are pressurized, and the relative pressure between the two sides is decreased or increased to move the piston in either direction. The position of the piston may be determined using position feedback, or with springs of known spring rates, two piston areas, and knowing the pressures of the two areas. The actuation device may be used with a selectable clutch to actuate an actuation cam, and may also have application with other clutches requiring the ability to achieve multiple positions and clutch modes.

  • Patent number: 10233999
    Abstract: An electric phaser dynamically adjusting the rotational relationship of a camshaft of an internal combustion engine with respect to an engine crankshaft includes an electric motor and a planetary drive. In some embodiments, the planetary drive includes a sun gear, planet gears, a sprocket ring gear driven by the engine crankshaft, a camshaft ring gear rotating with the camshaft, a carrier, a lever arm, and a load generator. The lever arm is rotatably attached to at least one planet gear and pivotably attached to the carrier at a pivot point on the carrier located off-axis from the sun axis. The load generator is coupled to the carrier and applies a torque load to the lever arm to reduce backlash in the split ring planetary drive.
