Landing gear with reinforcing web
A landing gear includes structural parts arranged to connect a wheel to a structure of an aircraft, each structural part including two or more interfaces for connection to one or more other of the structural parts or to the structure of the aircraft and two or more webs which extend so as to face one another while delimiting between them a free space and which connect the two interfaces in order to transmit the forces from one to the other.
1. A landing gear comprising structural parts arranged to connect a wheel to a structure of an aircraft and to withstand landing forces, each structural part comprising at least two interfaces connecting to at least one other of the structural parts or to the structure of the aircraft, and one of the structural parts ( 1 , 101 ) is a brace element characterized in that it comprises at least two webs ( 3 , 4 ; 102 , 103 ) which extend so as to face one another while delimiting between them a free space and which connect the two interfaces in order to transmit the forces from one to the other, in that one of the two interfaces comprises two first coaxial articulation bearings ( 5 ; 104 ) for articulating the structural part ( 1 , 101 ), and the webs ( 3 , 4 ; 102 , 103 ) are substantially triangular in shape, having two vertices adjacent to the two first bearings, and the other of the interfaces comprises a second articulation bearing ( 105 ) for articulating the bracing element, and in that each of the webs ( 102 , 103 ) has two sides formed by a beam ( 106 , 107 ) extending between one of the first bearings ( 104 ) and the second bearing ( 105 ).
2. The landing gear according to claim 1 , wherein at least one of the webs ( 3 , 4 ) comprises a peripheral extra thickness ( 33 , 34 , 43 , 44 ).
3. The landing gear according to claim 1 , comprising a rib ( 6 ) having two opposite edges secured to the webs ( 3 , 4 ) so as to extend transversely thereto.
4. The landing gear according to claim 1 , wherein the structural part is obtained by additive manufacturing.
5. The landing gear according to claim 1 , wherein each beam ( 106 , 107 ) of each web ( 102 , 103 ) is connected to the beam ( 107 , 106 ) of the other web ( 103 , 102 ) facing it by crossmembers ( 108 , 109 ).
6. The landing gear according to claim 5 , wherein each beam ( 106 , 107 ) of each web ( 102 , 103 ) has an end section in the vicinity of the first bearing ( 104 ) and the end sections of the beams facing each other are connected together by a wall ( 110 ).
7. The landing gear according to claim 5 , wherein the crossmembers comprise inclined crossmembers ( 108 ).
8. The landing gear according to claim 7 , wherein each beam ( 106 , 107 ) of each web ( 102 , 103 ) has an end section in the vicinity of the first bearing ( 104 ) and the end sections of the beams facing each other are connected together by a wall ( 110 ).
