    The invention relates to machine building.
    A known gearbox comprising a body mounted therein a fixed drive and driven shaft with two gear wheels on each two intermediate shafts with gear wheels meshed with the gear wheels of the drive and driven shafts, and friction clutches for shifting gears 1.
    The aim of the invention is to reduce the size of the gearbox.
    The goal is achieved by the fact that in the gearbox, including the case, installed in. it is axially stationary drive and driven shafts with two gears on each, two intermediate shaft, each of which has two gears, which are in constant engagement with the corresponding two gears of the drive and driven shafts, and friction clutch for gear shafts,; Intermediate shafts are installed coaxially one to another and each of them consists of two .coaxial parts, namely from the outer part and the inner part with a central hole, with two homogeneous, end The internal parts of both intermediate shafts are mounted in the housing stationary., and the other two parts can independently move axially inward from the rest position fixed by means of springs, the friction clutch consists of a central disk mounted with the possibility of moving in the axial direction rotation in the central apertures of the inner parts of the intermediate shaft and four disks parallel to the central disk, with edge zones protruding towards the central disk, these disks mounted on the ends of the outer and inner parts of the intermediate shafts facing each other, in the neutral transmission position the distance between the edge zones of the clutch disks located on the axially movable parts of the intermediate shafts is greater than the distance between the edge zones of the clutch disks located on axially fixed parts of intermediate shafts.
    FIG. Figure 1 shows a gearbox with axially movable inner parts of intermediate shafts, a cut along the shafts; in fig. 2 - the same, with the axially movable outer parts of the intermediate shafts.
    The gearbox contains a housing 1 in which the driving 2 is stationary axially mounted and
    3 shafts with two gears 4, 5 and 6, 7 on each, respectively. Parallel to shafts 2 and 3, two intermediate shafts are installed in housing 1, each of which consists of two coaxial parts — outer 8, 9, and inner 10, 11, respectively, the inner parts 10 and li-having central holes 12 and 13. On each of the parts of the intermediate shafts, the toothed wheels 14, 15, 16. and 17 are fixed, being in constant engagement with the corresponding gears 4,5, 6 and 7 of the driving 2 and driven 3 shafts.
    The homogeneous parts of the intermediate waves are installed either fixedly in the axial direction or movable (in FIG. 1, the outer parts 8 and 9 are fixed, and the inner-inner parts 10 and 11; in FIG. 2 vice versa). The moving parts of the intermediate shafts are connected to pistons 18 and 19 of cylinders 20 and 21 and are fixed in neutral position by springs 22 and 23.
    The gearbox also contains a friction clutch consisting of a central disk 24 mounted for axial movement and rotation in the central holes 12 and 13 of the internal parts 10 and 11 of the intermediate shafts, and four disks 25, 26, 27 and 28 rigidly mounted on the ends of the parts of the intermediate shafts facing each other parallel to the centrifugal disk 24. The disks 25, 26, 27 and 28 are provided with edge working areas 29, 30, 31 and 32 that project into the side of the central disk 24, 30, 31 and 32, respectively.
    The gearbox is equipped with an additional spurious gear 33, and the gear wheel 17 is vypylneno in the form of a block of two gears 34 and 35, which is mounted on the inner part 11 of the intermediate shaft with the possibility of axial movement.
    In the neutral position, the distance between the edge zones 29 and 30 of the disks 25 and 26 (Fig. 1) -il-and between the zones 31 and 32 of the disks 27 and 28. . Fig. 2) is longer than the distance between zones 31 and 32 of disks 27 and 28 (Fig. 1) or between zones 29 and 30 of disks 25 and 26 (Fig. 2).
    Transmission (Fig. 1) works as follows.
    When pressure is applied to both cylinders 20 and 21, pistons 18; and 19 with the inner parts 10 and il of the intermediate shafts moving towards each other and the disks 25 and 26 compress the central disk 24.
    The moment transfer occurs from the shaft 2 through the wheels 4 and 14, the disks 25, 24 and 26, the wheels 17 and 7 on the shaft 3.
    When the pressure in the cylinder 20 is depressed and the cylinder 21 is pressurized, the piston 18 with the intermediate shaft part 10 and the disk 25 is returned to its original position by the action of the spring 22, and the piston. 19 with the inner part 11 and the disk 26, overcoming the resistance of the spring 23, move even further, as a result of which the disk 26 is pressed against the disk 24 and moves it against the stop to the disk 27: the outer part 8 of the intermediate shaft
    The transmission of the moment in this case occurs from the shaft 2 through the wheels 5 and 15, the disks 27, 24 and 26, the wheels 17 and 7 on the shaft 2.
    When the pressure in the cylinder 21 is depressed and the cylinder 20 is pressurized, the piston 19 with the inner part 11 and the disc 26 is returned to its original position by the action of the spring 23, and the piston 18 with the inner part. ten
    and the disk 25, overcoming the resistance of the spring 22, moves until the disk 25, moving the disk 24, presses it against the disk 28.
    Then the transmission of the moment occurs from the shaft 2 through the wheels 4 and 14, the disks 25, 24 and 28, the wheels 16 and 6 on the shaft 2.
    In the absence of pressure in the cylinders 20 and 21, the box is in the neutral position.
    The operation of the gearbox (Fig. 2) is carried out similarly, only with axial movement of the wheel block
    17, either direct transmission from gear 35 to wheel 7 or reverse gear from gear 34 through a parasitic sheartern 33 to wheel 7 can be performed.
    The gearbox described is compact and easy to drive.
