Abstract
Official abstract text for this publication.
An actuator for hinging a first element to a second element about a first pivot axis (A 1 ), the actuator comprising a motor-drive device, a first mounting plate ( 4 ) connected to a body ( 2 ) of the motor-drive device, a second mounting plate ( 5 ) connected to the second element, the second mounting plate being mounted in the first mounting plate in order to pivot about the first axis, and a bush ( 6 ) mounted in the second mounting plate to pivot about a second axis (A 2 ) perpendicular to the first axis. The motor-drive device has an outlet shaft ( 3 ) pivotable about a third axis (A 3 ) perpendicular to the first axis and intersecting the first axis, and it is extended by a pin ( 7 ) that is pivotally received in the bush and that has a central axis (A 4 ) intersecting the first axis and the third axis, and forming an acute angle with the third axis. An aircraft guidance assembly including such an actuator.
First claim
Opening claim text (preview).
The invention claimed is: 1. An aircraft guidance assembly comprising a fixed structure having a movable flight control surface hinged thereto to pivot about a first pivot axis, and at least one actuator for hinging a first element to a second element about a first pivot axis, the actuator comprising a motor-drive device, a first mounting plate connected to a body of the motor-drive device, a second mounting plate connected to the second element, the second mounting plate being mounted in the first mounting plate in order to pivot about the first axis, and a bush mounted in the second mounting plate to pivot about a second axis perpendicular to the first axis, the motor-drive device having an outlet shaft pivotable about a third axis perpendicular to the first axis and intersecting the first axis, the outlet shaft being extended by a pin that is pivotally received in the bush and that has a central axis intersecting the first axis and the third axis, and forming an acute angle with the third axis, connecting the fixed structure to the flight control surface. 2. An assembly according to claim 1 , wherein the motor-drive device and/or the first mounting plate are fastened to the fixed structure and the second mounting plate is fastened to the flight control surface. 3. The assembly according to claim 1 , wherein the hinge connection between the mounting plates connects the movable flight control surface to the fixed structure and guides it in pivoting. 4. The assembly according to claim 1 , including a motor common to a plurality of actuators via a motion transmission system.
