    A clutch assembly capable of providing several predetermined settings, wherein the components which support springs applying torque are not subjected to bending loads. The settings are achieved in that a supporting ring supporting a pressure plate against a clutch housing is provided with radially outwardly extending cams which are offset relative to the center thereof with two rows of apertures being provided in a cylindrical face of the clutch housing which are axially offset and offset relative to the angle of rotation and which correspond to the cams of the supporting ring and within which the cams are engaged.

    1 The invention relates to a rearrangement, in particular, to a friction clutch for drive elements, in particular, associated with cardan shafts of agricultural machine drives with a tractor power take-off shaft.
    The aim of the invention is to improve performance and increase reliability by stabilizing the rated torque, improving the ease of adjustment and reducing bending stress.
    In Fig. 1, an adjustable clutch is given, a longitudinal section in Fig. 2 is the same, a top view of the clutch housing in Fig. 3 is the same, a top view of the intermediate ring in Fig. 4 is the same, a top view of the pressure plate; figure 5 is a section aa in FIG. 4; figure 6 - scan reference ring, partial view.

    Adjustable slip clutch
    (Fig. 1) consists of a housing 1 rotatably mounted. The pivot fork 2 is connected to the housing 1 for joint rotation for the purpose of transmitting torque over the drive shaft. The intermediate discs 3 are alternately connected to the housing 1 and to the inner part 4 of the clutch for joint rotation, but with the possibility of an axial displacement

     scheni Ring-shaped friction linings 5 are installed between the individual intermediate discs 3; Intermediate discs 3 connected firmly for joint rotation with the housing 1 are directed in the openings 6 of the housing 1. Axial pressure springs 7, causing a normal force, which causes torque, are partially mounted on the spacers rings 8 and rests on the one hand on the friction disk 3, and on the other hand on the pressure plate 9. The pressure plate 9 rests on the open side of the housing 1 on the support ring 10 provided with protruding adialno way of its outer cylindrical surface of the cams 11 which are received in corresponding recesses 12 in the body 1 of the coupling.
    To ensure that the set coupling is changed, the nuts 13 are provided on the spacer pins 8, by which the pressure springs 7 can be compressed by means of the pressure plate 9 with such force that the support ring 10 can be removed from its safety position and re-inserted into it an inverted position, as a result of which a change in the tightening of the springs 7 is obtained due to the displacement of the cams 11 radially outwardly directed relative to the middle, or to a different series of recesses
    12 in the housing 1, as a result of which a change in the tightening of the springs 7 is also obtained.
    The housing of the coupling (FIG. 2) is made with two rows of recesses 12 displaced axially relative to each other, but they correspond radially outwardly directed cams 11 of the support ring 10,
    The support ring 10 (fig.Z) is made with placed on it by radially directed outwards by the cams 11.
    The clamping ring 9 (figure 4) has axially in the direction of the support ring.10 supporting cams 14 and additional supporting cams 15 located in the direction of the pressure springs 7. While the first supporting cams 14 (figure 1) protect the support ring 10 From moving radially inward, the two additional supports of the cam 15, placed on both sides of the aperture 16 for the fingers 8, are designed to hold the pressure springs 7, when they are not mounted on the fingers 8, on the pressure plate. 9, to prevent them from moving.
    The support ring 10 (6) is partially deployed. Moreover, there is an axial displacement of radially outwardly directed cams 11 relative to the axial center of the support ring 10.
    Due to the interaction of axial displacement relative to the center of the radially outwardly directed cams 11 on the support ring 10 and the location of two rows of recesses 12 on the housing 1 of the coupling with axial displacement relative to each other, four installation options are obtained for changing the preload tension of the spring 7 and, as a result this and the nominal torque of the coupling.
    For example, at a given basic setting of the coupling of the positions of the fixed ring 10, the coupling can be installed only with increased torque, or, if desired, only with reduced torque, or the coupling can be installed at the factory in such a way that it is possible to change the torque within range. it is possible to set the upper and lower limits of the moment.
