HALF SYSTEM TORQUE BRAKES

摘要

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.

1. A half system torque brake for use with a first driven mechanism and a second driven mechanism, the half system torque brake comprising:
a compression shaft having a center axis; an input cam assembly slidably disposed on the compression shaft and associated with a driving mechanism; a first output cam assembly disposed on the compression shaft and movably coupled to the input cam assembly, wherein the first output cam assembly is associated with the first driven mechanism; a second output cam assembly slidably disposed on the compression shaft and movably coupled to the input cam assembly, wherein the second output cam assembly is associated with the second driven mechanism; and a rotor-stator assembly disposed on the compression shaft such that the second output cam assembly is disposed between the input cam assembly and the rotor-stator assembly, wherein the rotor-stator assembly comprises a rotor, a stator, and a pressure plate for engaging the rotor and the stator while compressing the rotor and the stator between the pressure plate and the second output cam assembly.
