  • Centrifugal brake for a gyroscope with Cardan suspension
    Patent number: 4355540
    Abstract: A centrifugal brake for a gyroscope with Cardan suspension in a fixed housing on a mobile support includes two weights, identical, of C shape, mounted in opposition on two, diametrically opposed cylindrical articulation pins or axles. The two weights form, by their construction, a ring in two identical parts permanently bearing on one another under the action of a spring. The weights are freely articulated, forming by simple construction an autocompensated brake against the inertial forces generated by combined accelerations of the support.
