    10 In the embodiment, the control lever 4 (Figures 1-6) is integral with the active zone 5, and the entire clutch fork is made from one blank by stamping. Fork 2
    15 of the control has a grooved cross-section with a bottom 6 and two side walls 7.
    The fork 2 controlling its pivotally 20 zone 3 is mounted on the bracket 8
    (FIG. 3), which in turn is mounted in the gearbox housing 9 (not shown). To provide turn3
    This clutch fork on the bracket is made of ball 10 and 10.
    The bracket 8 is located inside the cluster 9, and the control lever 4 of the control fork emerges from the housing 9 through the opening 11 provided for this.
    The ball pin is a bulge 12 in the bottom 6, having a shape similar to that of the ball 10. In this bulge 12 there is a hole 13 for the passage of the axis 14 of the bracket 8, which in practice is usually a screw. At the end of the control lever 4 under its further connection, an opening 15 is made. The control fork 2 is mounted for movement relative to the ball bar 10 in the circumferential direction and in a straight line.

    To act on the support surface of the flange 21 at two diametrically opposite points of this latter, the active zone 5 of the control fork 2 has two support points 26, referred to as main support points, which are located in the active axial plane, indicated by the dash-dotted line A (Fig. 2) 1Q and parallel to the plane of rotation P of the lever 4 controls. In addition, they are located at different distances from the hinge zone.
    Each of the main points of support 26 of the control fork 2 is made in the form of a spherical bob-shaped, obtained by punching in the bottom 6. The axis of such a bob is located in principle in the active axial plane A.
    However, in order to avoid the consequences of a possible deviation of these bosses relative to this plane A, the axis of the bosses can be slightly displaced in the transverse direction relative to this plane in the direction opposite to the middle part of the core 5. At the same time, at the core 5 by punching, at least at least one additional point of support 27, located between the main onoii-ngmi points 26. However, additional points 27 can be made in a quantity of - two,

    the control fork 2 between the active zone 5 and the release bearing 1 or, more precisely, the flange 21 of the moving element; 17 of this bearing, which evenly distributes the force perceived by it and acts on the manner of the frame with respect to the points of the support 26. The distribution part 31 has the shape of a hard disk 32, in the middle of which a hole 33 is made to put it on with a gap on the sleeve 20 of the moving element 17 of the release bearing 1. The peripheral edge 34 of the disk 32 is bent axially.
    Distributor part 31 may have a cruciform shape formed in the active plane A of the plug 2 controlling two levers 35 and two levers 36 perpendicular to this plane. The supporting surface of the flange 21 of the distributor part 31 abuts two diametrically opposite one another by cylindrical protrusions 37 formed by stamping and at an angle of 90 around the circumference relative to the main reference points of the core 5 of the plug 2 of the control.
    Each of the protrusions 37 of the distribution part 31 enters a recess of a corresponding form, which is provided on the bearing surface of the flange 21 of the movable element 17, and the active zone 5 of the control fork 2 controls at least its main support points 26 against this distribution body.
    In order to facilitate the assembly of the entire assembly, a connection bracket 38 is inserted into the socket of each of the projections 37, which is a stud of the appropriate shape. At its one end 39, this pin passes through the hole 40 in the bent edge 34 of the distribution part 31 and enters the hole between the corresponding protrusion 37 and the disk 32; The end 41 of another branch 42 bent at a right angle, parallel to the branch 39 of the stud and passing from the rear-flange 21 of the movable element 17, enters a hole 43 made in this flange (Fig. 4).
    Fixing the angular position of the release bearing 1 on its direction074036
    The mounting bracket 16 can, for example, be provided with a spring 44 (FIG. 1), hooked at one end to the bent edge 34 of the distribution part 31, and at the other end to a fixed point on the engine crankcase or foot that is on the crankcase.
    Alternatively, the sleeve 20 of the movable 10 element 17 of the release bearing 1 can be mounted using splines.
    The design can be used connecting, snap-fit means 45. The hinge of the control fork 2 can be made with a rotary shaft 46, and the control lever 4 can be made in the form of a coupling 47 fixed on the rotary shaft 46 by a bolt 48.
    The clutch mechanism is mounted and operates as follows.
    In the first stage of installation, the plug 2 25 of the control is installed inside the housing 9 on its bracket in such a way that its active zone 5 is in the transverse direction at some distance from the path along which the release bearing 1 has to move, i.e. somewhat away from its final position (Fig. 6).
    At the second stage, at the end of the relative axial approaching of the clutch assembly and the gearbox housing 9, the control plug 2 is affected so that its active zone 5 engages with the sleeve 20 and the release bearing 1. In this case, the control fork 2 on the bracket 8, which is a ball spot 10, is simply rotated in a plane perpendicular to the axis of the release bearing 1. Thereafter, a spring 30 is attached to it, which constantly presses the active zone 5 in the direction of the release bearing axis, pressing the track 29 side wall 7 of the fork to the guide face 28 of the sleeve 20 of the movable element 17.

    In the process of operation, the plug 2 of the control, by means of at least its main supporting points 26 of the core 5, abuts against the distribution part 31 or, more precisely, at the two levers 35 of this part. Because of the above-mentioned displacement of the main reference points 26 relative to the active axial plane A, the control plug 2 abuts the distribution part 5 also with at least one auxiliary reference point 27. In this connection, it is completely certain that due to this displacement, the rotation 2 that the fork 2 can make control under the transmission with which it is connected, around the intersection of its active axial plane A with its bottom 6, causes at least one of the auxiliary anchor points 27 abut against redelitelnuyu part 31, When turning fork engaging in the direction indicated by arrow F (Figure 1) for spinning the release bearing 1 dispensing part 5 is rotated about an axis perpendicular to the active axial plane A.
    During this rotation, the control fork 2 moves in the radial direction relative to the distribution part 31.
    It should be noted that the contact between the control plug 2 and the distribution part 31 is made on the flat surface of the latter.
    The cylindrical protrusions 37 (Fig. 7 of the distribution part 31 abut against the flat surface of the release bearing 1, which is practically the surface of the flange 21 of the movable element 17 of this bearing. According to this option, snap-in means 45 can be provided, which come into play during installation control fork 2 at the end of its rotation in the direction of the release bearing 1 axis and connect the plug to the distribution part 31. With this design variant, the distribution body is not only turning It comes in contact with the flange 21 of the movable element 17 when the control fork 2 is rotated, but also longitudinally moves, making such contact with the flange 21. On the other hand, in this case there is no relative sliding movement between the control fork 2 and the distribution piece five.

    Fig. 10 shows a variant of the design, when the clutch fork 2 is mounted on the rotary shaft 46. In this case, the control lever 4 can
    5 be made in the form of a coupling 47, worn with the possibility of longitudinal movement on the rotary shaft 46, and the control fork 2 is fixed from turning by a pointed bolt 48.
    10 In this case, the plane of rotation P of lever 4 of control does not coincide with the plane of rotation P of fork 2 of control, but is parallel to this plane of P. In accordance with the proposed
    15, when mounting the entire assembly, move the control fork 2 parallel to the axis of the rotary shaft 46 from the position represented by the dash-dotted line (in this position it allows 20 relative axial approach of the clutch assembly to the release bearing 1 and the gearbox housing 9) line (figure 10). In that
    25 position clutch fork is included. the engagement with the sleeve 20 in the region located between the active element 18 and the distribution part 31. In all cases, preferably,
