The invention, aiming to provide an improved actuator arrangement for operating a driven element with different actuators, proposes an actuator arrangement (110, 210, 310, 410, 510, 610, 710) comprising:
a first actuator (112, 212, 312, 412, 512, 612, 712) for driving a driven element (122, 222, 322, 422, 522, 622, 722) in a first direction (132, 232, 323, 432, 532, 632, 732) via a first output member (146, 246, 346, 446, 546, 646, 746; 1004) and a second actuator (114, 214, 314, 414, 514, 614, 714) for driving the driven element (122, 222, 322, 422, 522, 622, 722) in a second direction (134, 234, 334, 434, 534, 634, 734) opposite to the first direction (132, 232, 323, 432, 532, 632, 732) via a second output member (148, 248, 348, 448, 548, 648, 748; 1006), wherein the first and second actuators are configured to work in a counter-acting manner for moving the driven element (122, 222, 322, 422, 522, 622, 722) in said first and second directions;
characterized in that an additional connecting and supporting device (136, 236, 336, 436, 536, 636, 736; 1000) is connected between the first output member (146, 246, 346, 446, 546, 646, 746; 1004) and the second output member (148, 248, 348, 448, 548, 648, 748; 1006) for supporting the output members to bear transversal forces transversal to the moving direction and/or to bear pre-load force for pre-loading the actuators. |
