    The transmission comprises two slidable tripod joints. In each joint, the tulip element is extended around the shaft of the tripod element by an abutment member which defines a concave part-spherical surface. A check member having a convex part-spherical surface fitting the concave surface is disposed around the shaft between the tripod element and the abutment member with a radial clearance which is at least equal to the amplitude of the orbital movement of the tripod element at the maximum angle of deviation of the joint. Each joint has a spring which is compressed between the inner end of its tulip element and the adjacent end of the shaft. In this way, the maximum extension of the transmission is distributed equally between the two joints and the shaft is constantly centered so that noise and wear of the check members is avoided. The invention is in particular applicable to transmissions for independent rear driving wheels of automobile vehicles.

    The invention relates to mechanical engineering and vehicle transmissions can be used.
    Known homokinetic hinge A motor vehicle transmission comprising an intermediate shaft connected by means of cardan joints to the drive and driven shafts, each cardan joint including a hub, a three-hub assembly with rollers mounted on needle bearings mounted on an intermediate shaft with the possibility of axial displacement with respect to to the hub, and an elastic element in the form of a cylindrical spring in one of the hinges, located between the hub and the end of the intermediate shaft C13.
    The crawler device of the known device is the increased noise level of operation.
    The purpose of the invention is to improve the performance by reducing the noise level during transmission operation.
    This goal is achieved in that in a homokinetic swivel transmission of a motor vehicle containing an intermediate shaft connected by means of universal joints to the drive and driven shafts, each universal joint includes a hub, three-pinch knot of rollers mounted on needle bearings mounted on an intermediate shaft with the possibility of axial movement with respect to the hub, and an elastic element in the form of a cylindrical spring in one of the hinges, located between the hub and the end face The intermediate shaft, each cardan joint is additionally provided with a support part with an internal concave spherical surface encompassing the hub and a three-sleeve unit, and a disk with an external convex spherical surface mounted on the intermediate shaft with a clearance to the support part, while controlling the orient of another hinge also made in the form of cylindrical springs
    In addition, between the skirt of the three-j trunnion assembly and the skirt of the disk rest of each universal joint there is an elastic shock absorber.
    At the same time, the disk stop is mounted stationary axially on the intermediate shaft and has three racks separated by sectors, located between the hub flanges, with grooves in the form of a groove made on each rack from the hub side, and bevels on the opposite side, angled to the shaft axis .
    In addition, the disk stop is mounted on the intermediate shaft with axial mobility.
    Fig. 1 shows a hinge transmission, a sectional view along the axis of one of the hinges; Fig. 2 shows an embodiment of the cardan joint with an elastic shock absorber; Fig. 3 is an embodiment of the cardan drive with a disk stop fixed in the axial direction; Fig. 4 shows the projection of the stop (Fig. 3) onto a plane perpendicular to the axis of the intermediate shaft; in fig. 5 - aa in figure 4 (disk stop);
    5 in FIG. b is a section bb of fig. 5 (rack disk stop).
    The cardan ne (the feed (figure 1) connects the drive shaft (not shown) to the driven shaft 1 via the first sliding cardan joint 2, the intermediate shaft 3 and the second sliding cardan joint 4.
    The two cardan shafts 2 and 4 are the same, sliding trunks of triple type, located symmetrically with respect to the intermediate shaft 3, therefore one universal joint 4 is described below. The universal joint 4 contains a three pin node 5 mounted on the end of the shaft 3 ps by means an annular skirt 6. From the skirt 6 withdrawal radially three cylindrical axes 7, located at an angle of 120P to each other and on each of which is installed by means of a needle bearing 8, freely rotate the spherical roller 9.
    Each roller 9 is installed in the recess 10 of the hub 11, made
    0 is complete with the driven shaft 1. The undercuts 10 are transverse circular sections and are parallel to the axis of the end of the shaft 1, accurately describing each of the two raceways
    5 installed rollers 9 ..
    The hub ends with a flat surface 12 and has in its central part a recess 13 with a flat bottom perpendicular to the axis XX.
    0 The coil spring 14 is located between the bottom of the recess 13 and the spherically arched cup 15, located at the spherical end of the shaft 3 adjoining the cup and forming a ball
     support at this end of the shaft.
    The cardan joint 4 is equipped with a support part 16 made of sheet material, a part of which is mounted on the outer peripheral surface of the hub 11 and secured with a roll 17 of the edge opposite the shaft 3. A sealing gasket 18 is installed between the hub 11 and the support part 16 The chain 11 forms a segment of a sphere, the inner spherical surface 19 of which is coaxial with the end of the shaft 1, and is machined with the recess 20 to which the wide end of the elastic casing 22 is attached to the other end This casing is fixed with a clamp 23 directly on the shaft 3. The disk stop 24 forming the bearing surface is located in a space bounded by a spherical surface 19. This part is a rim 25 with a convex spherical surface 26 with a surface 19. The radial on the front part of the rim 25 is an annular recess made to reduce the weight of the part. From the inside of the other surface, the ring-shaped skirt 27, which has a flat cut, rim 25 and skirt 27 are made from one bridging and contain a central hole 28, which diameter is larger than the diameter of the shaft 3 by an amount sufficient for the radial gap to exclude a circular motion of this shaft with the maximum possible deflection angle corresponding to the maximum elongation of the cardan. The disk stop 24 has the ability to move freely in the axial direction on the shaft 3. The calculation is such that when the three node boom is at the maximum angle and is supported on the support piece 16 by means of the disk stop 24, the rollers 9 are located on the edge of the raceways of the hub 11, from which they can not go out. The skirt 27 of the stop 24 is long enough that in the position of maximum elongation of the hinge, the only contact between the three-node unit and the stop 24 is through the mutual contact of the skirts 6 and 27. The hub, the support part and the elastic case hermetically limit the space, delaying lubrication and protecting the mechanism from external factors . The homokinematic hinge transmission operates as follows. In normal operation, the intermediate shaft 3 axially oscillates around the middle position almost symmetrically with respect to the two cardan joints 2 and 4 and is supported near this position by the two springs 14, which compensate for the lateral accelerations of moderate magnitude caused by the road profile. Under these conditions, in each cardan joint, the disk stop 24 is free from all contact and is in an unstable position between the three-socket unit and the support part 16. Consequently, there is neither friction nor wear of this part. In the case of movement at maximum transmission elongation, both cardan joints work as follows. The skirts 6 of the three-capped units push the corresponding skirts 27 of the disk stops 24 and they, moving, leaning or almost resting their spherical surfaces 26 on the internal spherical surfaces 19 of the support parts 16, form a spherical connection. The maximum elongation of the transmission is therefore distributed evenly across the two pivot cardan joints 2 and 4, i.e. it is enough that the raceways of the hub operate at an angle of half of the rotation of the transmission. In all cases, the two springs 14 play an important role in distributing the stroke between the two universal joints and centering the shaft 3, which hinges the stops .24 and the supporting parts 16 from the contact. In addition, the rollers 9 can never touch the part 16 or the bottom of the undercut 10, which would cause serious inconvenience, causing a large amount of jerk and noise (cardan joints work at an angle during rotation. If there are lateral overloads applied to the transmission, then an elastic shock absorber 29 can be installed between the skirt 27 of the disk pack 24 and a skirt 6 of a three-hinged knot 5 (Fig. 2). This shock absorber can be made either of hardened corrugated steel, as shown in the figure, or of the Velville type f, or of dense or expanding elastic material. The shock absorber can also be replaced with a very short a coil spring, which is considerably more rigid than the spring 14. An emphasis 30 made of an elastic material (FIG. 2), located inside the spring 14, eliminates or reduces shocks from contact by adjacent turns of these springs. The disc stop 24 is intended only for cardan joints that rotate relatively within small limits. In fact, when the overall rotation of the universal joint is significant (lengthening causes strong compression), in order to ensure the normal operation of the universal joint in all positions, the disk stop must enter partially or completely into the hub without contacting its walls. To accomplish the foregoing, the disk stop 24 is fixedly mounted on the shaft 3 (FIG. 3) and has three
    sectors separating three radially directed posts 31, emerging from the skirt 27 and ending at the ends with a spherical surface 26 (Fig. 4-6. Each rack has an axial size the same as the skirt 27 and has a maximum width that allows it between the two flanges of the hub 11 and this width is reduced in the direction opposite to the hub, due to the bevels 32 executed on the uprights directed at an angle to the axis of the shaft 3, the outer surface 33 of the skirt 27 located between the uprights 31 has the shape of a truncated cone and converges in the direction , vs The hub of the notch 34 of the rack 31, rotated to the hub, made in the form of a groove on the stdron opposite cavity 35, made to reduce the weight of the part.
    The skirt 27 is held axially against the skirt 6 of the three-vest knot by a retaining ring 36 mounted on the shaft 3 with an emphasis on its protrusion 37.

    The rollers of the three-paired unit are installed each with a small gap in the notch 34 of the rack 31, which guarantees the adjustment of the angular installation of the stop 24 relative to the three-pole
    knot and, as a result, reliable entry of the rack 31 into the hub when the universal joint is working in compression.
    The proposed homokinetic transmission has the following
    o advantages: the complete absence of impacts and, therefore, noise in all cases and throughout the path traveled; use the same pivot shafts and distribution
    evenly between them axial movements of elongation and compression, each cardan thus has a minimum volume and -Sec; the axial movement is completely free, providing good filtering of vibrations and complete isolation of the drive units from the slaves and vice versa; long service life of hinges, since wear is distributed over the entire length of the rolling surface. 8 4
