Abstract
A backstop of a torque transmission device of an aircraft steering system includes input and output sections of a drive shaft. Torque is transmitted from the input to the output, but is prevented from being transferred from the output back into the input. The input is limited from rotating coaxially relative to the output by more than a predetermined angle. The input stops at a first rotary position relative to the output upon rotating in a first rotary direction. The input stops at a second rotary position upon rotating in the opposite direction. The output is blocked from rotating in the second direction while the input is at the first rotary position and is blocked from rotating in the first direction while the input is at the second rotary position. The output is blocked from rotating by dissipating any torque acting upon the output into the housing of the backstop.
