Abstract:
An asymmetry brake includes a housing, a shaft, a pilot brake, a primary brake, and a ball ramp assembly. The shaft of the asymmetry brake is rotatable relative to the housing about an axis of rotation. The primary brake is movably connected with the shaft. The pilot brake is configured to selectively engage the housing to generate a triggering torque. The triggering torque is transferred through the ball ramp assembly to the primary brake, which in response engages the housing to generate a braking torque on the shaft. The disposition of the ball ramp assembly between the pilot brake and the primary brake allows the ball ramp assembly to return to an operative non-separated condition when the pilot brake is disengaged from the housing. The return of the ball ramp assembly to the operative non-separated condition allows the primary brake to disengage from the housing which releases the shaft to rotate.
