ACTUATOR ASSEMBLY COMPRISING SHAPE MEMORY ADJUSTERS, AND OPERATING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/010711
Kind Code:
A3
Abstract:
The invention relates to an actuator assembly comprising a frame unit and a gear unit that is mounted on the frame unit and includes an output member, the kinematics of the gear unit featuring a first operating position and a second operating position that represents a limit position of the gear unit; the gear unit is designed in such a way that the output member runs through a dead position during the transition of the gear unit from the first operating position to the second operating position; the actuator assembly further comprises a gear unit drive comprising shape memory adjusters including an agonistic adjusting element and an antagonistic adjusting element. The invention is characterized in that the agonistic adjusting element comprises a first shape memory element and the antagonistic adjusting element comprises a second shape memory element, which elements are contracted in the longitudinal direction during activation; the first end of the first shape memory element extends from a first holder on the frame unit, and the second end of the first shape memory element is secured to a first movable holder that is in an indirect driving connection to the gear unit via an intermediate element; the first end of the second shape memory element extends from a second holder on the frame unit, said second holder being closer to the first movable holder than to a second movable holder.
