Wheel actuator locking mechanism

An aircraft undercarriage comprising:

• at least one wheel;
• a support;
• a drive system for driving rotation of the wheel, the drive system being movable relative to said support between an engaged position relative to the at least one wheel and a disengaged position relative to the wheel;
• a mover system connected to the drive system in order to move the drive system between the engaged and disengaged positions;
• a first pair of links that are hinged to each other about a first hinge axis of this first pair of links, the first pair of links being arranged in such a manner that during the movement of the drive system between the engaged and disengaged positions, the first pair of links pivot relative to each other about said first hinge axis of the first pair of links;
• and
• a locking actuator and at least one first target, the locking actuator being arranged to act on at least the at least one first target in such a manner as to selectively lock the drive system in the disengaged position, the at least one first target being carried by one of the links of the first pair of links.
