    For relative engagement on one side of the thrust bearing, which engages, being attached by its actuating element 2 to the deactivating mechanism 6 of the latter, and on the other side of the drive fork 3, which is mounted on the gearbox housing, operate according to the invention
    At the same time, the axial engagement of the coupling and the said housing, on the one hand, hold the driven fork 3 noticeably perpendicular to the bearing axis, and on the other hand, as shown in solid lines in FIG. 3, a spring 31, properly fixed for this purpose at a fixed point, for example rigidly connected to said housing at its other end, holds the thrust bearing control element 1 in an angular position at which the radial
    the legs 28 and 29 of the axial support that it has are in the angular displacement between the fingers 5 of the drive fork so that they can axially enter between the latter, and in the second phase, at the end of the mentioned axial approach, after relative axial engagement - fingers 5 of the drive fork behind the radial legs 28 and 29 of the axial bearing of the thrust bearing control element turn the control around the axis of the bearing until these radial legs of the axial stop are directly opposite the fingers of the drive fork 5, as shown in punk dashed lines in FIG. 3,
    The limited expansion attached to the axial planes of the axial bearing 22 and 23, makes it possible to avoid with such a rotation of the control element 1 around the axis of the node any mutual opposition of the axial planes 22 and 23 of the axial direction and the fingers 5 of the drive fork 3, and this rotation in the direction in which, as indicated by the arrow F in FIG. 3, the axes 22 and 23 of the axial direction extend entirely each above the mean axial plane P of the bearing.
    In order to maintain the final angular position of the control element 1 with respect to the actuating element 2, it is sufficient in the present embodiment to fix the spring 31 at another corresponding fixed point, as schematically depicted by solid lines in FIG. 2
    In practice, in the present embodiment, this second fixed point is at a 90 ° angle with respect to the first one.
    The spring point may be formed by a pin (not shown) inserted for this purpose in one or the other of the housings in question.
    The spring is preferably located so as to act in a direction perpendicular to the planes 22 and 23 of the axial direction.
    In an embodiment, maintaining the final angular position of the control element instead of accomplishing this by means of npv
    As in the previous embodiment, it can also be implemented by means of a rod or finger, a pin or similar, properly inserted between such a control element and a point that is not under control.
    In the same way, it can be for the angular position of this control element, which is required for axial engagement of the coal bearing I; when the axles 5 of the drive fork 3,
    In order to preserve the arms of the lever that forms the drive fork, and to reduce the radial dimension of the knot, the internal profile of the free end of this drive fork 3 contains between the hinged middle zone 4 of this drive fork 3 and-one 5 at least from the drive pins 5 last, a ledge 32 for the passage of the radial paws 28 of the axial bearing of the thrust bearing control element during axial engagement of the latter between the driving fingers 5.
    The internal profile of the free end of the drive plug 3 comprises a protrusion 33 protruding outward, directly opposite the hinge middle zone 4 of the last protrusion 33, and on one side and on the other side, behind the inflection point, a ledge 32 going inward.
    According to the embodiment illustrated in FIG. 4, each of the rotating legs 28 and 29 of the axial support of the control element 1 has an external peripheral contour generally rounded in a semicircle.
    In addition, in this embodiment, for knots of the width of the drive fork, as well as minimizing the pepper bearing dimension, each of the axial direction planes 22 and 23, which contain this control element 1 on the bricks 26 and 27 and from which one can be seen in the figure , runs in the plane tangential to the control element bushing.
    To facilitate processing, the groove 34. which runs parallel to the axis of the assembly thus delimits, on the side, each of these axes 22 and 23 of the axial direction when the latter mates with the sleeve 7 as invented.
