ACTUATOR ARRANGEMENT AND CONTROL SURFACE ARRANGEMENT, ESPECIALLY FOR AN AIRCRAFT

摘要

An improved actuator arrangement for operating a driven element with different actuators. The actuator arrangement comprises a first actuator that drives a driven element in a first direction via a first output member and a second actuator that drives the driven element in a second direction opposite to the first direction via a second output member. The first and second actuators are configured to work in a counter-acting manner to move the driven element in the first and second directions. An additional connecting and supporting device is connected between the first and second output members to support the output members to bear transversal forces transversal to the moving direction and/or to bear pre-load force for pre-loading the actuators.

1. An actuator arrangement comprising:
a first actuator configured to drive a driven element in a first direction via a first output member; a second actuator configured to drive the driven element in a second direction opposite to the first direction via a second output member, such that the first and second actuators are configured to work in a counter-acting manner to move the driven element in the first and second directions; and an additional connecting and supporting device connected between the first output member and the second output member and configured to support the output members to at least one of bear transversal forces transversal to the moving direction and bear a pre-load force to pre-load the actuators.
