    This invention relates to the automotive industry. The purpose of the invention is to reduce the transverse dimensions and increase transmission efficiency. The locking system consists of a planetary gear and a braking device acting on the carrier of this planetary gear. The planetary gear is composed of an input ring gear 8, rigidly connected to a drive shaft 6 mounted coaxially on bearings, rigidly connected to the output shaft 13 of an output ring gear 9 with a slightly smaller number of teeth, and also from several simultaneously engaged with each other. ring gears rotating planetary wheels 20 together with a planet carrier. 3 Il.

    This invention relates to the automotive industry.
    The purpose of the invention is to reduce the transverse dimensions and increase transmission efficiency.
    FIG. 1 shows a diagram of the all-wheel drive vehicle; in fig. 2 - locking system on all wheels, longitudinal section; in fig. 3 - section A-A in FIG. 2
    The drive engine 2 mounted near the front axle 1 on the vehicle, with the drive gear box 3 attached to it through the bevel gear 4 and the driven flat bevel gear 5 drives the front axle 1. From the bevel gear 4, the drive shaft 6 goes to the splined one mounted on it the connection 7, having internal gearing, the wheel input ring gear 8 of the planetary gear
    Coaxially, the inlet crown neck 8, next to it, is mounted on bearings an output crown gear 9, which is pressed at the landing site on the side surface 10 of the housing 11, which tightly encloses the locking system. Outside on the right front side 12 of the housing 11, there is a driven shaft 13, which, through a bevel gear 14 and a flat bevel gear 15, leads the rear axle 16 of the car. Coaxially with the driven shaft 13 through the left end side 17 of the housing 11 passes the drive shaft 6, abutting bearings 18 and 19 on the left 17 and right 12 end sides of the housing 11.
    With the input ring gear 8 and the output ring gear 9, three planetary wheels 20 are simultaneously engaged, which are symmetrically positioned along the circumference of the ring gears 8, 9. Planetary wheels 20 are mounted on bearing fingers 21, which are pressed into a V-shaped planetary gear gears 22. The planetary gear carrier on bearings 23 and 24 rests on the drive shaft. A brake element 25 formed in the form of a bowl with blades, which represents one half of the hydrodynamic coupling, is formed on the planetary gear carrier 22. The second bowl with blades acts as a conjugate

    The brake element 26 is made in one piece with the right side 12 of the housing 11, centered and fixed in the side surface 10 of the housing 11. Both bowls together form a toroidal annular flow cavity 27, which is filled with hydraulic fluid and relative to the rotation of the bowls shear fluid transmits the corresponding braking torque.
    The input ring gear 8 has the number of teeth, the output ring gear 9 is the number of teeth, so the gear ratio for the direct through drive is 54:51. The gear ratio of the gear train to the planet carrier 22 is 18: 1. If there is a difference in the number of revolutions between the front and rear axles and, therefore, such a difference in the number of revolutions between the drive 6 and the driven 13 shafts, then the planetary carrier rotates at an 18-fold speed of that difference. Due to the relative rotation of the brake element relative to the adjacent brake element, a braking torque occurs corresponding to the difference in the number of revolutions, which contributes to the synchronous movement (rotation) of the front and rear axles.
    Due to progressively increasing mu- sic hydrodynamic braking moment at small values of slip, the blocking moment retains small values. The car is well controlled and the antilock braking system retains its full functionality. For large amounts of skidding, for example, if the wheels of the front axle 1 slide on ice and the wheels of the rear axle are standing on rough asphalt, the blocking torque rises steeply and ensures smooth moving even in this extreme case.
