Publication number: 20240044385Abstract: A motor sub-assembly for an electromechanical brake actuator of an aircraft wheel includes a casing, a shaft mounted in the casing, and an electric motor mounted in the casing rotate the shaft, the shaft having an end connected to a screw-and-nut assembly to exert a force on a stack of disks for braking the aircraft wheel. The shaft has a first set of teeth and the motor sub-assembly has a shuttle mounted to slide relative to the casing and provided with a second set of teeth. The motor sub-assembly includes a selector mechanism that moves the shuttle selectively between first and second positions in which the first set of teeth is engaged and disengaged with the second set of teeth, respectively. The motor sub-assembly includes a holder device that holds the shuttle in the first position and a locking device that continuously prevents the shuttle from rotating relative to the casing.Type: ApplicationFiled: December 1, 2021Publication date: February 8, 2024Applicant: SAFRAN LANDING SYSTEMSInventors: Nathanael RICHARD, Romain PRESLE, Laurent SCHWARTZ, Mathieu GENGOUX

Patent number: 9638278Abstract: The invention relates to an electromechanical actuator for a vehicle brake comprising a body (4) in which are arranged an electric motor (5) and a threaded plunger cooperating via a helical link with a nut (8) driven in rotation by the electric motor (5). According to the invention, the nut (8) is mounted to move axially in the body (4) of the actuator between a rest position towards which the nut (8) is pushed back by elastic means, and an active position towards which the nut is displaced against the elastic means when a braking force is applied, the actuator further comprising means for detecting the axial displacement of the nut.Type: GrantFiled: November 14, 2014Date of Patent: May 2, 2017Assignee: MESSIER-BUGARRI-DOWTYInventors: Franck Selles, Eric Evenor, Nathanael Richard

Publication number: 20150266568Abstract: The invention relates to an electromechanical brake actuator for an aircraft wheel, comprising an electric motor (2) with a stator (3) and a rotor (4), a screw/nut assembly, of which one of the elements is rotationally driven by the motor and the other of the elements is compelled to slide without rotation to selectively exert a force on a stack of discs, the actuator comprising a park blocking member (10) suitable for selectively blocking the rotor of the motor at least when the sliding element exerts a force on the stack of discs. The park blocking member comprises a shuttle (17) that can move between a stable position of blocking of the rotor of the motor and a stable position of freeing the latter under the action of a pulse actuator (22, 24, 25) switching the shuttle from one position to the other, the brake actuator comprising means (9, 18) for forcing the shuttle to the freeing position when the motor of the brake actuator is powered.Type: ApplicationFiled: March 11, 2015Publication date: September 24, 2015Applicant: MESSIER-BUGATTI-DOWTYInventors: Eric EVENOR, Nathanael RICHARD, Guillaume DURAND
