摘要： An aircraft undercarriage having a leg for mounting to move on an aircraft structure between a deployed position and a retracted position is provided. The undercarriage generally includes a brace member arranged between the structure of the aircraft and the leg in order to stabilize the leg in the deployed position, and a drive actuator for moving the leg from the deployed position to the retracted position. The brace member includes a strut arm having a proximal end that is designed to be hinged on the structure of the aircraft. The arm presents a longitudinal slot extending until the slot reaches a distal end in order to terminate in a bend and having slidably engaged therein a finger that is secured to the leg, the drive actuator being coupled to the strut arm.

摘要： An aircraft landing gear structure according to the present disclosure includes a strut assembly and a wheel assembly operatively coupled to the strut assembly. The strut assembly includes an upper tubular housing and a lower tubular housing configured to be longitudinally translated with respect to the upper tubular housing such that the overall length of the strut assembly is transitioned between an extended configuration and a retracted configuration for stowage during flight. The wheel assembly includes a forward link pivotally coupled to the upper tubular housing and a truck beam that is pivotally coupled to the lower tubular housing such that translation of the lower tubular housing with respect to the upper tubular housing causes pivoting of the forward link and the truck beam with respect to one another, thereby tilting and/or raising a wheel of the wheel assembly with respect to the upper tubular housing.

摘要： A landing gear has a rigid structure and a gear compartment. A leg has a wheeled first end on a rolling shaft, and a second end secured on the rigid structure. The leg rotates between a rolling position, letting the aircraft rolls, and a landing gear storage position. A brace has a first end secured on the rigid structure. A guide bar has a first end pivotably secured on the leg, and a second end secured on the second end of the brace by a pivot shaft. A jack is secured between the brace by a pivot connection with a shaft parallel to the rolling shaft, and the guide bar, by a pivot connection with a shaft parallel to the rolling shaft. A locking system locks either a second end of the brace or the second end of the guide bar against the leg in the rolling position.
