Abstract

A coupling e.g. for an actuator, comprises a housing which is preferably in the form of a ring mounted around the end of the outer rod and which can be mounted to a component e.g. a cowl being deployed. Within the housing of the coupling is provided a ring disk. This is sized and arranged within the housing such that there is some clearance between the ring disk and the housing so as to permit some eccentric movement.

First claim

The invention claimed is:

1. An actuator assembly comprising;
a first moveable component; and
a second moveable component, moveable relative to the first moveable component;
wherein the first and second moveable components are arranged to actuate, in use, respectively, first and second moveable parts;
wherein the first moveable component is an outer rod and the second moveable component is an inner rod arranged for telescopic movement within the outer rod; and
a coupling assembly, the coupling assembly comprising:
a housing configured to be fixedly attached to a fixed component, and
a moveable element arranged inside the housing and arranged to be fixed to the outer rod,
wherein the moveable element is arranged in the housing such that it has freedom of movement within the housing in an eccentric path in two dimensions in response to a force exerted on the outer rod component such that a force transmitted to the first moveable component by movement of the second moveable component is accommodated by eccentric movement of the moveable element within the housing.

2. The actuator assembly coupling of claim 1 , wherein the housing is in the form of a ring and the moveable element comprises a ring or annular disk mounted within the housing for eccentric movement relative to the housing.

3. The assembly of claim 1 , wherein the eccentric movement is in a plane perpendicular to the axial direction of the outer and inner rods.

4. The assembly of claim 1 , wherein the coupling assembly is attached to the inner rod.

5. The assembly of claim 1 , wherein the actuator assembly is an actuator assembly for a TRAS system for use in an aircraft and wherein the first and second moveable parts are first and second flaps of the aircraft.
