Abstract:
1. An actuator assembly adapted to selectively cause an input disk of a clutch/brake assembly to engage an output disk of a clutch/brake assembly, the actuator assembly comprising: a movable piston integrated with the clutch/brake assembly, at least a portion of the clutch/brake assembly defining an expansible chamber in combination with the piston, the piston being movable in the clutch/brake assembly to selectively cause the input disk to engage the output disk; a housing positioned remotely from the clutch/brake assembly; a fluid compressor located within the housing, the fluid compressor being operable to generate a fluid pressure and provide the fluid pressure to the expansible chamber to move the piston; and a pressure switch fluidly connected with the expansible chamber to detect a level of the fluid pressure wherein the pressure switch is selectively triggered by the level of the fluid pressure, and wherein the pressure switch selectively electrically connects the fluid compressor and a power source to operate the compressor.
