摘要： A telescopic actuator comprising a cylinder having a structure for coupling the cylinder to a first external element a rod mounted to slide telescopically in the cylinder along a sliding axis and including a structure for coupling it to a second external element and a lead screw mounted to rotate in the cylinder about the sliding axis and extending inside the rod to co-operate with a nut secured to the rod, such that rotating the lead screw causes the rod to slide. There also is a drive structure for driving the lead screw in rotation and a retention structure for axially retaining the lead screw. The retention structure holds a bearing of the lead screw captive in an axial direction and is arranged to retain the bearing of the lead screw with axial clearance suitable for absorbing movements imparted to the rod relative to the cylinder.

摘要： An aircraft undercarriage includes a steerable bottom portion carrying one or more wheels and fitted with a steering device configured to turn the steerable bottom portion in response to a steering order. The steering device has a single electromechanical steering actuator having a steering electric motor driving, by a reduction gearing, an outlet pinion on an axis of the steering electric motor. The outlet pinion cooperates with a spur gear secured to the steerable bottom portion. A connection between the steering electric motor and the steerable bottom portion is reversible. The electromechanical steering actuator is fitted with a monitor configured to monitor at least one operating parameter of the steering device and to detect an actuator performance deterioration condition.

摘要： A locking device for locking together first and second elements that are movable relative to each other in an axial direction. The device has a bushing secured to a first element and catches that are cantilevered-out in an axial direction and are elastically deformable. The device also has an anchor portion secured to a second element and an annular setback to receive hook-shaped ends of the catches. The device also has a locking sleeve mounted to move relative to the catches between a release position in which the catches are free to flex, and a blocking position in which the catches are prevented from flexing, wherein the locking sleeve is movable in rotation relative to the catches and includes a circumferential succession of gaps and of obstacles.

摘要： The invention provides a locking device for locking together first and second elements that are movable relative to each other in an axial direction, the device comprising firstly a bushing secured to first element and including catches that are cantilevered-out in an axial direction and that are elastically deformable, and secondly an anchor portion secured to the second element and including an annular setback to receive hook-shaped ends of the catches, the device also including a locking sleeve mounted to move relative to the catches between a release position in which the catches are free to flex, and a blocking position in which the catches are prevented from flexing, wherein the locking sleeve is movable in rotation relative to the catches and includes a circumferential succession of gaps and of obstacles, such that: when the sleeve is in a first angular position corresponding to the release position, the gaps are in register with the catches which are therefore free to flex under the effect of the anchor portion moving; and when the sleeve is in a second angular position corresponding to the blocking position, the gaps are offset relative to the catches such that the catches are in register with the obstacles of the locking sleeve, thereby preventing the catches from flexing when their ends are engaged in the setback in the anchor portion.
