Abstract:
1. An asymmetry brake apparatus comprising: a housing; a shaft rotatable relative to the housing about an axis of rotation; a pilot brake configured to selectively engage the housing to generate a triggering torque; a primary brake movably connected with the shaft and configured to engage the housing to generate a braking torque on the shaft; and a ball ramp assembly operatively connected to and disposed between the pilot brake and the primary brake, wherein the ball ramp assembly has a first ball ramp connected to the pilot brake and a second ball ramp movably connected to the primary brake and balls disposed between the first and second ball ramps, wherein the balls separate the first and second ball ramps in response to the triggering torque from the pilot brake and the second ball ramp actuates engagement of the primary brake with the housing to generate the braking torque on the shaft.
