Abstract
Ce dispositif de verrouillage pour actionneur électromécanique comprenant un tube cylindrique (3) qui est mobile par rapport à un cylindre externe (2) fixe, sous l'action de moyens moteurs d'actionnement, et des premiers moyens libérables (8) de verrouillage du tube cylindrique dans le cylindre externe fixe. Il comporte des deuxièmes moyens libérables (9) de verrouillage complémentaire du tube cylindrique (3) fonctionnant indépendamment des premiers moyens de verrouillage et interposés entre les moyens moteurs et le tube cylindrique, les deuxièmes moyens libérables (9) de verrouillage comprenant un tube intermédiaire (25) apte à être entraîné par les moyens moteurs et un ensemble d'au moins un crochet (30) s'engageant dans une empreinte. Ledit ensemble de crochets et l’empreinte sont placés l'un sur le tube intermédiaire et l'autre sur le tube cylindrique. Figure pour l’abrégé : Fig 1This locking device for an electromechanical actuator comprising a cylindrical tube (3) which is movable relative to a fixed outer cylinder (2), under the action of actuation motor means, and first releasable means (8) for locking the cylindrical tube in the fixed outer cylinder. It comprises second releasable means (9) for complementary locking of the cylindrical tube (3) operating independently of the first locking means and interposed between the drive means and the cylindrical tube, the second releasable locking means (9) comprising an intermediate tube (25) capable of being driven by the drive means and a set of at least one hook (30) engaging in a cavity. Said set of hooks and the imprint are placed one on the intermediate tube and the other on the cylindrical tube. Figure for abstract: Fig 1
