Abstract
A ball ramp mechanism is used to load a clutch pack in a transmission inertia brake to slow a rotating shaft where an armature having an angled peripheral surface engages a mating surface formed in an inertia brake housing to form a cone clutch where the armature is magnetically pulled toward the brake housing by an electromagnetic field generated by an electrical coil thereby introducing a frictional braking force on the armature. The armature is nonrotatably connected to the control ring of the ball ramp mechanism through a plurality of tapered pins which engage a corresponding plurality of conical sections so that relative rotation between the armature and the control ring causes the armature to be forced toward the housing thereby increasing the braking force on the armature and control ring. Relative rotation between the control ring and an actuation ring causes a plurality of rolling elements to transverse tapered grooves formed on the control ring and the actuation ring thereby axially expanding the ball ramp mechanism to load the clutch pack.
