ABSTRACT:
A ball ramp mechanism having a control ring acting with an actuation ring to apply a clamping force on a driveline clutch during both a vehicle driving mode and a vehicle coast mode using a planetary gearset acting with a one-way clutch between a sun gear and meshing planetary gears to define rotation of the control ring with respect to the actuation ring in a direction tending to further activate the ball ramp mechanism. In the vehicle drive mode the planetary gearset is locked by the one-way clutch and in a vehicle coast mode the one-way clutch releases and the planetary gearset rotates the control ring through a coil pole in a direction to further activate the ball ramp mechanism.
