Structura mecanismului |
| Funcţie |
The lengths of the mechanism’s elements verify these conditions: AE=DF and EF=AD, that’s means AEFD is a parallelogram. The elements 4 and 3 turn around fixe axis A and D of the fuselage of the plane.
The element 1 composed of the wheel a form a rotation frame E with the element 4 and a rotation frame B with the elements 2 which form a rotation frame too (C) with the element 3.
The element 3 form a rotation frame G with the cylinder axis 5, mobil around of a fix axis H of the plane’s fuselage.
When the axis 5 mount in body of the cylinder (6), the elements 1 and 3 pivot to the fleche’s senses and the mechanism takes the indicated position, enabling the landing train lifting of the plane.
When the landing train is left, the elements 1, 4 and 2, 3 fix themselves in their extreme positions and form a stiff system. |
