  • Publication number: 20200152406
    Abstract: The disclosure relates to an assembly for preloading a cable rotary-pendulum kinematic system, in which a rotational motion of a rotary body is converted into a translational motion of a winding body by winding cables, to which rotary body a torque may be applied. The assembly includes: a rotary body of a cable rotary-pendulum kinematic system, which rotary body is to be preloaded, may be rotated about the longitudinal axis thereof and is immovable in the direction of the longitudinal axis; at least one gas spring, which surrounds the rotary body and which may be compressed in the direction of the longitudinal axis; and primary cables, which force-lockingly connect the rotary body to the gas spring in such a way that a rotational motion of the rotary body causes compression of the gas spring, whereby the assembly is preloaded. The assembly has the advantage that no undesired oscillations occur in a cable rotary-pendulum kinematic system.

  • Patent number: 10468214
    Abstract: Various embodiments may include a coupling element for an electrical switching device comprising: a first switching contact at a first end of a winding body; a second switching contact; and a rotating body through which the winding body extends. The rotating body rotates on the winding body and the winding body translates along its longitudinal axis. A cord is arranged on each of the two sides of the rotating body between the rotating body and the winding body so that winding and unwinding of the cord is caused by opposite rotational movements of the rotating body driving a translational movement of the winding body. The rotating body is coupled to two springs so that a spring force always acts on the rotating body in both directions of rotation. A lock blocks the rotating body in at least two extreme positions of the translational movement of the winding body.

    Abstract: The hydraulic actuator comprises: a hydraulic input cylinder having an input piston; a hydraulic output cylinder, which is hydraulically coupled to the input cylinder; and a pressure-limiting valve, which limits the output cylinder with respect to pressure in dependence on the usability of a force on the input piston. The method is a method for operating such a hydraulic actuator, wherein the drive actuator is deflected with deflections having a deflection duration at a deflection frequency for the duration of an acting or a non-acting phase of the hydraulic actuator, wherein the deflection duration defines a movement stiffness of the hydraulic actuator and the deflection frequency defines the resulting deflection speed of the hydraulic actuator.
