Abstract:
1. A control device for bidirectionally actuating a control member comprising: a control drive; a coupling unit coupled on a drive side to the control drive for performing bidirectional control motions and on an output side to the control member to be bidirectionally actuated, wherein the coupling unit has a drive element on the drive side coupled to the control drive, wherein the coupling unit has an output element on the output side coupled to the control member and to the drive element via a joint for transferring tensile and compression forces in a longitudinal axis of the output element, wherein the joint has at least two degrees of freedom, a first degree of freedom configured to allow pivot motions between the drive element and the output element about a transverse axis running in the joint transverse to the longitudinal axis, and a second degree of freedom configured to allow linear motions between the drive element and the output element in the joint running parallel to the transverse axis, wherein the drive element has an end opposite the output element, the end having an axial bearing for supporting a drive member of the control drive in a longitudinal axis of the drive element, the drive member configured to be rotatable about the longitudinal axis.
