Electromechanical aircraft brake with tiltable actuators
View Patent ↗The invention relates to an electromechanical brake, in particular for aircraft, the brake comprising a support carrying at least one electromechanical actuator comprising a pusher that is axially displaceable towards friction elements in order to apply a braking force to the friction elements, selectively, wherein the actuator is mounted on the support via a connection member allowing at least a portion of the actuator carrying the pusher to tilt angularly.
1. An electromechanical brake, the brake comprising:
friction elements,
at least one electromechanical actuator, said at least one electromechanical actuator comprising :
a housing,
a pusher that is moveable within said housing,
a driving member comprising an electric motor that actuates said pusher, and,
a transmission unit comprising a screw-and-nut system that is driven in rotation by said driving member and that drives in translation said pusher so as to move axially the pusher towards said friction elements in order to apply a braking force to the friction elements, selectively,
and,
a support carrying said at least one elecromechanical actuator,
wherein both said driving member and said transmission unit extend inside said housing,
wherein said at least one actuator is mounted on said support via a connection member that couples said housing to said support, allowing at least a portion of the actuator carrying the pusher to tilt angularly, whereby the pusher as a whole can entirely tilt angularly with respect to the support.
2. A brake according to claim 1 , in which the connection member comprises a ball joint.
3. A brake according to claim 1 , in which the connection member comprises a bearing that is substantially undeformable in an axial direction and that is deformable in radial directions.
4. A brake according to claim 3 , in which the bearing is arranged to filter vibration coming from the friction elements during braking.
5. A brake according to claim 4 , in which the bearing is a composite bearing including a bushing made of anisotropic elastomer material.
6. A brake according to claim 1 , in which the actuator as a whole, including at least the housing and pusher, can entirely tilt angularly with respect to the support.
