Abstract
Provided are half system torque brakes, aircraft utilizing these brakes, and methods of installing these brakes. A half system torque brake includes an input cam assembly slidably disposed on a compression shaft between first and second output cam assemblies. The second output cam assembly is disposed between the input cam assembly and a rotor-stator assembly. When a torque differential between the input cam assembly and either one of the output cam assemblies exceeds its threshold, the same rotor-stator assembly is engaged and prevents further rotation of any cam assembly. Specifically, when the torque differential corresponding to the first output cam assembly exceeds its threshold, this assembly advances away from the input cam assembly and pulls the compression shaft in the same direction, which in turn engages the rotor-stator assembly by advancing the pressure plate to the second output cam assembly. The second output cam engages the rotor-stator assembly directly.
