    The tubular portions located radially inwardly from the retaining protrusions, and the tubular portions are arranged one against the other, concentric with respect to the adjacent ends of the output shafts and with a gap, while the retaining rings also contain at the adjacent ends of the tubular portions radially inwardly directed inner annular flanges of the spring holders, and two springs are installed between the retaining rings and the side gears, respectively.
    In addition, each of the clutch followers is provided with teeth, one radial part of them is in contact with a leading crosspiece, the tooth of the latter having a rectangular shape, and the other radial part of the teeth of the follower elements is in contact with the central cam, and its tooth has a trapezoid shape.
    - At the same time, each end of each slot is provided with a pair of holding shoulders.
    Figure 1 shows the differential mechanism, a longitudinal section J in figure 2 - the central cam, rear view; on fig.Z - section aa in figure 2, figure 4 - section bb in figure 2, on fig.Z - clutch, rear view; figure 6 - section bb In FIG. FIG. 7 shows the holding ring, rear view j in FIG. 8 - section GGD in Fig.7.
    The differential mechanism 1 serves to actuate the two output shafts 2 and 3 from the input or drive shaft 4 via pinion gear 5, ring gear 6, detachable housing 7, ring driving element 8, non-rotatingly mounted in housing 7, and two driven elements 9 and 10 couplings, which are mounted on slots for axial movement on side gears 11 and 12, non-rotatingly connected to output shafts 2 and 3, respectively. A central cam 13 is mounted in the driving element 8 of the cross and concentric with it, which is kept from relative axial displacement by means of an elastic split spring retaining ring 14. The driven member 9 of the coupling is equipped with teeth 15
    484
    (Fig. 6), while their number and shape correspond to the shape and number of teeth of the driving member 8. Similarly, the driven member 10 is equipped with the same teeth interacting with the teeth of the driving member 8. Splines made on the axial direction of the lifting element 9 couplings, interact with the corresponding splines nz side gear 11 and a similar spline connection is made between the element 10 and the side gear 12.
    The proposed device also contains two identical split spring retaining rings 16 and 17, mounted concentrically and displaced radially outwardly into friction engagement with corresponding driven members 9 and 10 of the coupling. The retaining ring 16 comprises a radially outwardly directed annular flange 18, which enters a continuous groove formed on the inner circumferential surface of the follower element 9, with the result that the retaining ring has a rotational connection with the coupling element 9 but is axially deflected relative to it. In addition, the retaining ring 16 has a radially inwardly directed body 19, provided with a large number of circumferentially protrusions 20 that extend axially through corresponding slots 21 made in the inner peripheral surface of the central cam. The other holding ring 17 is also provided with a radially outwardly directed flange and an inwardly extending body with a large number of circumferentially protrusions 22, extending axially through the other ends of the through slots 21 made in the central cam. As shown in FIG. 4, the slots 21 have a stepped shape in cross section, forming the shoulders 23. At each end of the center cam 13 there are teeth 24 that engage with the teeth of the followers 9 and 10 of the coupling, respectively. As shown in FIG. 3, the shape of the teeth 24 differs from the shape of the teeth of the followers of the clutch B in order to realize the performance of the driven
    the coupling element interacting with the rapidly rotating output shaft,
    Split sting retaining rings also contain even ;. The tubular shaped portions 25 and 26, which are axially positioned one against the rim and concentric with respect to the adjacent ends of the side gears 11 and 12 and the output shafts 2 and 3, respectively. At the adjacent ends of the retaining rings are made directed radially inside
    28 holders, respectively, flanges 27 and, holding rings 16 are preferably made by stamping, but other manufacturing methods can be used.
    The followers 9 and 10 are typically in the engaged state with the driving member 8 under the action of the pressure springs 29 and 30, concentrically mounted around the adjacent ends of the side gears 11 and 12, respectively. With their distant ends, the springs interact with the fixed shoulders on the side gears, and with their neighboring ends the springs transfer the required inward bias force of the followers 9 and 10 through the annular flanges1. | 27 and 28 on retaining1: e rings 16 and 17 respectively.
    As long as the output shafts 2 and 3 rotate at the same speed, the torque is transmitted from the input drive shaft 4 to the output Hbte of the driven shafts 2 and 3 through gear 5, ring gear 6, housing 7 driving element 8, driven members 9 and 10 clutches and side gears 11 and 12 respectively. Right now: the retaining rings 16 and 17 are in the non-operating position, in which their protrusions extend in the axial direction 1; through the Central part of the slot 21, made in the Central Cam. The teeth of the followers 9 and 10 of the coupling are engaged with the corresponding teeth of the crosses 8 and the central cam 13.
    Suppose that the left shaft 2 rotates faster than the right shaft 3, for example, when turning. Due to the shape of the left teeth 24 of the central cam as compared with the shape lel ::, x teeth 24 of the follower 9, the latter gradually shifts to the left relative to the side gear 11, overcoming the force of the springs 29, as a result of which the teeth of the cross 8 and the follower 9 are disengaged. of the rotating element 9, the relative rotational displacement between the intersection of the crosspiece 8 and the driven element 9 leads to the fact that the retaining ring 16, which is in friction interaction with the driven element 9, starts rotationally to shift to the working position, shown by the dotted line in FIG. 4, as a result of which the free end of the protrusion 20 abuts against the surface of the flange 31 of the slit 32 made in the central cam, thereby keeping the coupling element 9 in the uncoupled vibration-free position.
    When the rotational speed of the shaft / becomes equal to the rotational speed of the rotary shaft 3 at the end of rotation 1, the retaining ring is shifted to the non-operating position relative to the slots made in the central cam, under action, which causes the pulse to change to the right and its tooth ;, T in engagement with the teeth of the leading cross 8,
    The right retaining ring 17 works in a similar way with the only reason that Bpatia accelerates the output 3.
    The invention allows to simplify the differential, mechanism by the mind; 1) the number of parts, which reduces the complexity of the assembly and reduces the cost, as well as (and; 5) the strength of the retaining rings, which improves the reliability of the mechanism.
