В корпусе 1 соосно с ведущим валом 2 размещены вал 3 водила 4 и первый ведомый вал 5, параллельно им - втоперемещением муфты 11 влево соединить промежуточный вал 8 с шестерней 9.In the housing 1 coaxially with the drive shaft 2, the shaft 3 of the carrier 4 and the first driven shaft 5 are placed; parallel to them, by moving the coupling 11 to the left, connect the intermediate shaft 8 to the gear 9.

При понижающей передаче переключающие муфты 11 и 13 занимают крайнее левое положение, жестко соедин - щес- 5 терню 9 с промежуточным валом 8 и щестерню 12 с ведущим валом 2 соответственно . Фрикцион выключен. Вращение от вала 2 через муфту 13 подводитс к шестерне 12 и от нее к шестерне 9. 10 От шестерни 9 вращение передаетс через муфту 11 промежуточному валу 8 и выполненной за одно целое с ним шестерне 10, от нее - водилу 4 и далее, как описано дл пр мой передачи.When downshifting, the switching sleeves 11 and 13 occupy the extreme left position, rigidly connecting the 5 – wheel 9 to the intermediate shaft 8 and the yoke 12 to the driving shaft 2, respectively. The friction is off. The rotation from the shaft 2 through the coupling 13 is supplied to the gear 12 and from it to the gear 9. 10 From the gear 9, the rotation is transmitted through the coupling 11 to the intermediate shaft 8 and the gear 10, which is made in one piece with it, and drove 4 and further as described for direct transmission.

The transfer box works as follows.

Claims

Invention Form

The initial position of the switching 30 other rotations of the satellites 21 and the solar couplings 11 and 13 when the friction clutch 18 is off corresponds to a neutral gear. The rotation from the drive shaft 2 is transmitted through the switching clutch 13.

on gear 12 and from it to gear 9. „......

The latter, in this case, is not connected 5 of the coupling 13 and 11 to the carrier by the coupling 11 with the intermediate shaft 8 and rotates idle. In this case, gears 9 and 12 can be provided with a selection of the capacity for the drive of the additional equipment during the stationary state of DO means, containing in the body the driver, the vehicle, the intermediate and the driven shafts, the transformer, for direct transmission, the clutch 11 and the friction clutch cool switching moment

Couplings and placed coaxially with the driving and first driven shafts axle unbalanced differential, sun position and rigidly connects shafts 2 and 3. The 45 turn of which is connected by a constant gear is supplied from the driving shaft 2 to the gear with the gear of the second driven shaft, and the device differential lock, characterized in that, in order to increase patency and

braking performance

15 through gears 14 and 7 - to the secondary, on its drive and intermediate driven shaft 6, and from the epicyclic shafts with a possibility of free rotation there is a pair of gears of permanent engagement, while the drive shaft is provided with a switching coupling for zi

driven shafts, depending on the internal gear respectively, with one gear and with the shaft of the gear ratio of the interseevogodil, and the intermediate one is equipped with a switching clutch for communication with the other spherical pair and has a cantilevered one

Option 18 is located at the positions indicated for neutral transmission. The switching clutch 13 occupies the extreme right.

through the clutch 13 to the shaft 3, the carrier 4 and is transmitted through the axes 20 of the satellites 21 and the satellites 21 of the solar 15 and the epic 16 gears, then from the sun gear 16 to the first driven shaft 5. In this case, the torque is distributed between the first 5 and second 6

differential. For power take-off on the drive of the additional equipment, it is sufficient when driving in direct gear

move the coupling 11 to the left to connect the intermediate shaft 8 with the gear 9.

In downshifting, the switching sleeves 11 and 13 occupy the extreme left position, rigidly connecting the gear 9 with the intermediate shaft 8 and the brush 12 with the driving shaft 2, respectively. The friction is off. The rotation from the shaft 2 through the coupling 13 is supplied to the gear 12 and from it to the gear 9. From the gear 9, the rotation is transmitted through the coupling 11 to the intermediate shaft 8 and the gear 10, which is made in one piece with it, and drove 4 and further, as described for direct transfer.

When the transfer case is operated in direct and downshifts, in these cases, a differential drive vehicle
