Abstract
A ramp/roller freewheeling clutch (FIG. 2) has a driving member with ramps 19 adapted to wedge rollers 21 against the driving surface 28 of a driven member 29 when the driving member 13 is rotated in the driving direction. The rollers are positioned adjacent the ramps by a primary cage 22, which can be rotated with respect to the driving member 13 so as to force the rollers out of engagement with the ramps 19 and into recesses 20. A secondary cage 39 disposed in fixed relation with the driving member 13 has cam surfaces 37 such that rotation of the primary cage to disengage the rollers forces them up the ramps and locks them in place with the recesses 20 of the driving member 13, thereby to avoid contact with the driven member 29 when the clutch is disengaged.
