ABSTRACT:
The three mode overrunning bi-directional clutch has a first mode where the slipper race and fixed race are coupled and power is not transmitted between the inner input shaft and the outer shaft. A second mode where the slipper race is uncoupled from the fixed race and the slipper race engages the outer shaft to provide power transmission between the inner shaft and the outer shaft. The third mode couples the slipper race to the fixed race but uses a brake to provide radial force against the slipper race to allow for partial engagement between the slipper race and the outer shaft. This third mode allows for a smooth transition between the first mode and the second mode.
