Reversible decoupling device for actuators

摘要

A reversible decoupling device is connected to an electromechanical actuator. The reversible decoupling device has an energy storage element configured to store the energy required for a decoupling in the decoupling device. The decoupling device can be re-coupled again after a completed test run so that the decoupling functionality can be easily tested.

1. A reversible decoupling device for an actuator element having a drive unit, which includes first and second actuator drive elements configured to functionally interact to change a length of the actuator element, the reversible decoupling device comprising:
decoupling mechanism, which comprises
a decoupling drive element;a first force element;a second force element;a first form-fit element; anda second form-fit element; wherein the first force element is configured to hold the first form-fit element in a closed position; wherein the decoupling drive element is configured to move the first form-fit element from the closed position to a form-fit released position; wherein the second force element is configured to move the second form-fit element from a closed position to a form-fit released position; wherein the second force element is blocked by a positive fit of the first form-fit element such that the second form-fit element cannot be moved to the form-fit released position; and wherein the second force element is configured to move the second form-fit element to the form-fit released position in which a positive fit of the first form-fit element is released; wherein the decoupling mechanism is configured to decouple an output piston from one of the first and second actuator drive elements so that the change in length of the actuator element is achievable independently of the drive unit and without decoupling the first drive element and the second drive element.
