    Homokinetic joint of the type in which the torque is transmitted between two ends by balls engaged in races or tracks made in said ends. Each track is constituted by two semi-cylindrical grooves, the sectional diameter of which being oriented relative to a radial axis passing through the geometrical center of the joint and perpendicular to the longitudinal axis of said two ends. The balls are thus made to roll and to be guided between two poles located on the radial axis and two other poles located on an axis perpendicular to said radial axis. Said arrangement excludes the use of any intermediate means for maintaining the balls on the bisecting plane of the joint. The invention is particularly adapted to realize the two-joints transmission assembly for a vehicle.

    The invention relates to mechanical engineering and can be used in npii rotary drives with reverse torque transmission, with the drive and driven shafts absorbing axial and angular displacements relative to each other.
    A hinge of equal angular velocities is known, comprising outer and inner heads, balls placed in raceways formed by grooves, made on facing surfaces of heads, and a device for forcing the balls to move when the angle between the shafts changes to the bisector plane. The device is a lever connecting the outer and inner heads, and the separtor hingedly connected to it, in the holes of which the Clj3 balls are placed.
    The disadvantage of this hinge is its structural complexity associated with having a device for moving the balls.
    A universal hinge of equal angular velocities is known, comprising an outer and an inner head, balls placed in the raceways formed by grooves made on the surfaces of the heads t23 facing each other.
    A disadvantage of the known hinge is also its structural complexity.
    To ensure the self-alignment of the balls in the bisector plane of the intersecting master and slave
    At the same time, it is necessary to introduce at least two pairs of balls, each of which transfers the rotation in mutually opposite directions.
    The aim of the invention is to simplify the design by ensuring that the balls are self-mounted in: the bisector plane of the intersecting shafts while simultaneously reversing the transmission of rotation.
    This goal is achieved due to the fact that in the universal joint of equal angular velocities, containing the outer and inner heads, balls placed in the raceways formed by grooves, filled with facing surfaces of the heads, the diametrical planes of the grooves coincide with the bisector angle plane, formed by two planes, one of which is the plane of symmetry, passing through its geometric center and the center of the ball, and the other through the center of the ball perpendicular to the first plane, the axis d Roller tracks are located in the plane of symmetry of the ball, the inner and outer heads are installed with a gap one relative to the other.
    The longitudinal axes of the grooves, forming a rolling track, are intersecting in the bisector movable plane of the hinge, forming equal angles with the longitudinal axis of the head, in which the groove is made. . Another embodiment of the hinge is to perform it in the form of a transmission by additionally providing it with an inner and outer head, an intermediate shaft connecting the inner heads, and a device for maintaining the Intermediate shaft in a balanced state. FIG. 1 shows a hinge equipped with two balls for transmitting rotation between the heads in FIG. 2 - external hinge head; in fig. 3 - the internal head of the hinge; in FIG. 4 is a four-track hinge assembly; in FIG. 5 - three-track hinge assembly; in fig. 6 shows the inner head of the three-track hinge in FIG. 7 shows a hinge with six lanes, a slit in FIG. 8 - hinge with grooves parallel to the axis of rotation of the head; in fig. 9 shows a paired hinge and a device for keeping the intermediate shaft in a neutral position, a general view. The hinge of equal angular velocities contains outer 1 and inner 2 heads, balls 3 placed in raceways formed by grooves 4 intersecting with the diametrical plane 5. The latter is the bisector plane of the angle between two planes, one of which 6 is plane symmetry of the head passing through the center of the ball 3. The second plane, perpendicular to the plane of plane 6, also passes through the center of the ball. When the hinge is rotated, the balls move along the grooves in the direction of the axis 7 of the outer 1 head and the axis 8. of the inner 2 head. The gutters 4 are inclined at the same angle with respect to the axis of rotation of the heads. i Options for making the hinge are four-track (figure 4, three-track (fig. 5 and 6); seeks for a track (figure 7) versions. The option is the same hinge, in which the axes of the grooves 4 are parallel to the axis of rotation of the corresponding head (figure 8). An embodiment is also a hinge, additionally equipped with external and internal heads, an intermediate shaft and a device for keeping the shaft in a balanced state (Fig. 9). The device for supporting the shaft is springs 9 attached by one the end, to the outer heads 10, and the other to the intermediate shaft 11. To protect against contamination, install the housings 12. The hinge operates as follows. The torque is transmitted between the heads 1 and 2 using balls 3 located in the grooves. relative to the plane 6, the placement of the diametrical plane 5, each ball 3 can transmit rotation in the forward and reverse direction. The equal inclination of the grooves 4 to the longitudinal axes of the heads 1 and 2, on the surface of which they are located, provides constants rotational speed when the angular position of the driven and driving shafts. The only possible location of the balls 3 at the angular position of the axes of the heads and, accordingly, the axes of the drive and driven shafts is the overlap zone of each pair of grooves. At the same time, the grooves of the outer 1 and inner head 2 form in the overlap zone a nest in which the ball is placed. When the angular position of the shafts changes, all the sockets formed by the overlap zones of each pair of grooves 4, and, accordingly, each ball 3 located in this nest, are located in the bisector plane of the axes of the intersecting shafts. This ensures a constant rotational speed within each revolution of the hinge. This applies equally to hinges with any number of balls. Due to the design of the hinge, the spontaneous movement of the balls in the bisector plane eliminates the presence of additional mechanisms for the forced movement of the balls. The use of hinges with more than two lanes significantly reduces the pressure on the balls in any direction of rotation (Fig. 4-7).
    During the operation of hinges, in which the axes of the grooves are parallel to the axes of the heads, as in the previous cases, the spontaneous movement of the balls into the bisector plane of the junction with the intersecting shafts takes place (Fig. 8).
    The use of such hinges is possible in gears where the angular position between the shafts does not change. ) An important advantage of all the described hinges is the assumption of translational movement of the heads 1 and 2, one relative to the other. This reduces the load on the balls 3, increasing the reliability of the transmission.
    The hinges are assembled by sequentially inserting the balls.
    3 in channel 4 so that the overlap zone of the next pair of channels, where -: the ball is inserted, is outside the hinge. For this, the outer and inner heads are inclined relative to each other by an angle larger than that assumed under operating conditions.
    The use of twin hinges 1 (Fig. 9) is advisable in vehicle drives. In this case, it is possible to use one of the hinges in a non-slip version, and the second in a sliding one. The presence of return springs and covers allows the inner and outer heads to escape from the engagement zone.
