Abstract
A switchable clutch, including: a first race including a pocket; a second race radially offset from the first race; a pawl including a portion disposed in the pocket and pivotable within the pocket; and a cage radially disposed between the first race and the second race and including a ramp. The ramp includes: a first surface; and a second surface sloping radially and circumferentially from the first surface. The first surface does not slope radially along a first circumferential direction. In a locked mode of the switchable ratcheting clutch, the pawl is in contact with the first surface and the outer race, and the first race and the second race are non-rotatably connected. In a freewheel mode of the switchable ratcheting clutch, the pawl is in contact with the second surface, and relative rotation of the first race with respect to the second race is enabled.
