Assembly between an aircraft pylon and a turbine engine

1. A suspended set of an aircraft, the suspended set comprising:

an aircraft structural pylon adjacent to a pad and having a first bore;

a turbine engine; and

an assembly between the aircraft structural pylon and the turbine engine, with the assembly comprising a beam attached to the turbine engine and wherein a knuckle for receiving the pad is mounted, with the beam comprising suspension lugs, each of the suspension lugs including a second bore for the passage of a shaft which further passes through the first bore to connect the beam with the aircraft structural pylon, wherein the knuckle is disposed at a distance from the shaft so that the shaft does not pass through the knuckle.

2. The suspended set of claim 1 , wherein the knuckle comprises a C-clamp mounted to rotate in an external body of the knuckle integral with the beam, with said C-clamp providing a passage intended to be gone through by the pad.

3. The suspended set of claim 2 , wherein the pad is oriented vertically, goes through a lower opening of the external body of the knuckle, and has a lower end provided with a locking head intended to cooperate with said external body of the knuckle in case of failure of at least one of the suspension lugs and the shaft, to provide the holding in suspension of the turbine engine in a degraded mode of operation, the external body of the knuckle then coming into contact with the locking head and supported by the pad via said locking head.

4. The suspended set of claim 3 , wherein the locking head provided by the pad comprises a threaded part at said lower end of the pad and a nut screwed about the threaded part, with said nut being adapted to support the external body of the knuckle in the degraded mode of operation.

5. The suspended set of claim 2 , wherein the external body of the knuckle is integral with the suspension lugs.

6. The suspended set of claim 1 , wherein clearance is provided between an external body of the knuckle and at least one of the aircraft structural pylon and, towards the aircraft structural pylon, a shoulder provided on the pad, to create a ball effect.

7. The suspended set of claim 1 , wherein:

the second bore in each of the suspension lugs extends along an axis, and

first and second bushes are respectively mounted in the respective second bore of each of the suspension lugs, about said shaft and have shoulders with an axial clearance relative to outer surfaces of the suspension lugs opposite which said shoulders are respectively positioned.

8. The suspended set of claim 1 , further comprising a finger integral with the aircraft structural pylon, at a distance from said pad and extending in a direction parallel to that of the pad, with said beam having an oblong orifice extending in a direction extending through the finger and the pad, and wherein the finger is adapted to be engaged with a clearance in said direction.

9. The suspended set of claim 1 , wherein the turbine engine is a multi-flow turbojet engine of an aircraft, with the multi-flow turbojet engine comprising:

in a front portion of the multi-flow turbojet engine, an engine fan having a fan casing; and

a gas generator accommodated inside an assembly of at least one casing and comprising, behind the engine fan, compression stages, a combustion chamber area, and turbine stages,

wherein the suspended set comprises a front hooking system interposed between the fan casing and a structure of the aircraft, and a rear hooking system interposed between a rear part of the assembly of at least one casing and the structural pylon of the aircraft, and

wherein the rear hooking system comprises the aircraft structural pylon.

10. The suspended set of claim 1 , wherein the turbine engine is a multi-flow turbojet engine, with the multi-flow turbojet engine comprising:

in a front portion of the multi-flow turbojet engine, an engine fan having a fan casing; and

a gas generator accommodated inside an assembly of at least one casing and comprising, behind the engine fan, compression stages, a combustion chamber area, and turbine stages,

wherein the suspended set comprises a front hooking system interposed between a front part of the assembly of at least one casing and the structural pylon of the aircraft, and a rear hooking system interposed between a rear part of the assembly of at least one casing and said structural pylon of the aircraft, and

wherein the front hooking system comprises the aircraft structural pylon.

11. The suspended set of claim 1 , wherein:

the pad extends along an axis along which globally flows from upstream to downstream a flow of fluid to be circulated therein; and

the first bore through which passes the shaft is transverse to said axis.

12. The suspended set of claim 1 , wherein the suspension lugs are integral with beam and extend on both sides of the aircraft structural pylon.

13. The suspended set of claim 1 , wherein the knuckle comprises a ball joint.

14. The suspended set of claim 1 , wherein the knuckle comprises a ball knuckle.

15. The suspended set of claim 1 , wherein the knuckle is configured to provide a ball effect.

16. The suspended set of claim 1 , wherein aircraft structural pylon is connected to the pad.
