  • Patent number: 11850731
    Abstract: Various embodiments include a robot unit for a technical apparatus comprising: a base connecting the robot unit to the technical apparatus; a first member pivot-mounted on the base; and a second member pivot-mounted on the base or the first member. The first member and the second member are each movable in one direction relative to a degree of freedom by a separate actuator. The first member and the second member are only movable together counter to the direction relative to the degree of freedom by a single counter actuator device.

  • Patent number: 10851808
    Abstract: An actuator comprising: a piezo actuator; a drive having a drive chamber and a drive piston element driven by the piezo actuator; a first output having an output chamber and a piston element; and a second output having an output chamber and a piston element. At least part of the hydraulic fluid is conveyed out of the drive chamber by movement of the drive piston element and into the first output chamber. At least part of the hydraulic fluid is conveyed out of the drive chamber and into the second output chamber. The second output piston element has a hydraulically active second output face which is different in size from the first output face. There may be a coupling device mechanically coupling the first output piston element to the second output piston element.

  • Patent number: 10690154
    Abstract: A piezohydraulic actuator system includes four chambers: a first chamber defined by a drive bellows filled with a hydraulic fluid and movable by a piezo actuator, a second chamber defined by a hydraulic cylinder filled with the hydraulic fluid, which defines a first output; a third chamber defined by an output bellows filled with the hydraulic fluid, which defines a second output; and a fourth chamber defining a reservoir of the hydraulic fluid. The drive bellows is hydraulically connected via a first check valve to the second chamber. A hydraulic piston in the hydraulic cylinder is coupled mechanically to the output bellows. The drive bellows is hydraulically connected via a second check valve to the fourth chamber. The hydraulic fluid reservoir is hydraulically connected via a third check valve to the output bellows, and the hydraulic cylinder is hydraulically connected via a fourth check valve to the output bellows.

  • Publication number: 20190145432
    Abstract: The hydraulic actuator comprises a hydraulic drive cylinder, a first hydraulic output cylinder which is hydraulically coupled to the drive cylinder, and a pressure valve which limits the pressure on the output limiting cylinder depending on an action time of a force on the drive cylinder and/or output piston, wherein the pressure limiting valve is arranged opposite a second output cylinder for limiting pressure and/or in a second output cylinder for relieving pressure, and wherein the second output cylinder is hydraulically coupled to the drive cylinder. 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.

  • Publication number: 20170207692
    Abstract: Embodiments relate to a magnetic coupling, comprising a first coupling part, that can be rotated about an axis of rotation, a second coupling part, that can be rotated about the axis of rotation, and at least one coil, that is configured to generate a magnetic field along the axis of rotation through the first and second coupling parts for contactless transmission of a torque between the first and second coupling parts. A magnetic coupling having a magnetic field along the axis of rotation reduces forces that act on the coupling parts in a radial direction.
