Abstract
A landing gear for an aircraft, characterized by upper and lower pintle frame members (38, 40) being connected to a telescoping shock strut (14) in a non-rigid manner that tolerates twisting when reacting to torsional loads applied to the landing gear, and/or by a pitch trim actuator (30) that positions a landing gear truck (16) proportionally to the retraction angle of a shock strut (14) during retraction and extension.
Claims6
A landing gear for aircraft comprising:
- a pitch trim actuator operatively connected to a landing gear truck and a shock strut to position the landing gear truck proportionally to the retraction angle of the shock strut during retraction and extension, wherein the landing gear truck includes a truck beam that carries one or more axles for respective pairs of wheels;
- and
- a torque link assembly including a pair of torque links that are pivotally connected to one another at a pivot connection, wherein the pitch trim actuator is connected to the torque link assembly with the pitch trim actuator and torque link assembly connected between the truck beam and the shock strut for positioning of the truck beam by using rotation of a drag brace assembly connected to the shock strut to reposition the truck beam via the pitch trim actuator and torque link assembly.
