A landing gear system for an aircraft comprises a truck beam (22); at least one steerable axle (42) mounted to the truck beam for pivotal steering movement; a steering actuator (46) connected to the steerable axle; and a locking mechanism (60) including a locking groove member (62) provided on the steerable axle for pivotal movement therewith, and a locking wedge member (64) engageable with the locking groove member to prevent pivotal movement of the steerable axle. The locking groove member includes a slot (63) having opposed sides converging towards one another, and the locking wedge member has correspondingly converging sides for mating engagement in the slot. The locking wedge member is resiliently biased (66, 69) into engagement with the locking groove member and the locking wedge member is mounted to the truck beam for pivotal movement (70).

La présente invention se rapporte à un système train d'atterrissage pour avion, qui comprend : un basculeur (22) ; au moins un essieu dirigé (42), monté sur le basculeur pour décrire un mouvement d'orientation pivotant ; un actionneur d'orientation (46), relié à l'essieu dirigé ; et un mécanisme de verrouillage (60), qui comprend un élément rainure de blocage (62), qui est placée sur l'essieu dirigé de manière à pivoter avec ce dernier, et un élément coin de blocage (64), qui peut venir en prise avec l'élément rainure de blocage pour empêcher l'essieu dirigé de pivoter. L'élément rainure de blocage est doté d'une fente (63) possédant des côtés opposés qui convergent l'un vers l'autre, et l'élément coin de blocage possède des côtés convergents correspondants destinés à venir en prise par couplage dans la fente. L'élément coin de blocage est sollicité de manière élastique(66, 69) pour venir en prise avec l'élément rainure de blocage, et l'élément coin de blocage est monté sur le basculeur de manière à pivoter (70).
