Abstract:
In a differential coupling having a body, having a rotary input member and having two rotary output members, the algebraic sum of the angular displacements of said output members being proportional to the angular displacement of said input member, the improvement comprising:a detent mechanism operatively arranged to prevent relative angular displacement between said output members whenever the difference between the torques acting on said output members is less than a first predetermined value, and to allow relative angular displacement between said output members whenever the difference between the torques acting on said output members is greater than said first predetermined value; a brake mounted on said body and operatively arranged to be selectively applied to brake rotation of said input member; and a differential mechanism having a mechanical output proportional to the relative angular displacement between said output members, and operatively arranged to cause said mechanical output to energize said brake.
