The output shaft 27 of the gearbox 2 is coupled to the housing 33 of the differential 5, which has kinematic connections 34 and 35 with the wheel gears 36 and 37 of the driving rear wheels of the vehicle (not shown). In this connection, the connection 34 with the left gearbox 36 is performed through hollow shafts 27 and 28.

The transmission (Fig. D) is made in the form of a detachable monoblock consisting of modules (torque converter 1, gearbox 3, planetary gear 4, differential 5), and is fixed directly to the rear axle beam (not shown) coaxially to the wheel gearboxes. In this case, the links 34 and 35 can be ordinary semi-axes.

In particular cases, the torque converter 1 can also be installed separately from the gearbox near the engine or directly on it. Then the kinematic link 21 is made in the form of a cardan shaft.

In the embodiment (Fig. 2), the differential 5 is installed in the gearbox 3 of the gearbox 2, its body 33 is connected to the output shaft 27 with an additional gear pair 38-39 and a zero shaft 40. In this case, the kinematic connections 34 and 35 of the wheel differential 5 Gearboxes 36 and 37 can be made in the form of cardan gears, which makes it possible to install the transmission on the rear axle itself not rigidly, but with spacing. In the particular case of the transmission can be installed above the rear axle on the frame of the vehicle (not shown).

Transmission works as follows.

In the first stage, the friction clutch 24 is engaged according to the table.

and brake 31. The torque is transmitted from the input shaft 6 through torque converter 1, shafts 21 and 17, gears 19 and 20, gears 18, 15 and 16 and then through coupling 24 to the crown pin 22 of the first differential, and then through satellites 26 - on carrier and output shaft 27 (crown gear 30 of the second differential

at this time braked by brake 31). In the second and third stages, the friction clutches 9 and 10 are alternately engaged and the brake 23 closes. The torque is transmitted to pairs of gears 11 -12 or 13-14, and then through shaft 8 to the sun.

gear 28 of the first differential, the corona P1estern of which is braked by the brake 23, and then through the satellites 25 and drove to the output shaft 27.

In the fourth stage, friction clutches 24 and 32 are turned on. Torque

is transmitted through the gear pair 15-16 and the clutch 24 to the ring gear 22, and the planetary mechanism is blocked by the clutch 32, i.e. rotates as one piece. On the fifth and sixth steps, friction clutch 24 is continuously engaged, and clutches 9 and 10 alternately turn. Twisting moment is transmitted by two flows through kinematic connections 6 and 7 to the crown 22 and solar 28 of the first differential, and output to the output shaft 27

performed via satellites 25 and 26 and the carrier.

The seventh and eighth stages are obtained alternately by the inclusion of friction clutches 9 and 10 with the clutch 32 engaged.

The reverse gear is obtained by alternately switching on the clutches 9 and 10 with the brake 31 permanently closed. The torque in this case is transmitted through the H-stern 11--14 to the sun gear 28 of the first differential gear.

the potential, and the corona radar 30 of the second differential is braked by the brake 31.

Kinematic schemes (Fig. 1 and 2) are deployed in the same plane. In practice, in order to reduce the dimensions of a monoblock transmission, it is advisable to use its mechanisms in space as in FIG. 3. The axis of the torque converter and the shaft 21 are located above the axis of the planetary mechanism 4 by the value of H and the kinematic connections 34 and 35, located coaxially or with a slight displacement relative to the axles of the rear wheels, by the value of // a. Due to this arrangement, the need for a special layout gearbox is eliminated, because of which the misalignment of the engine and the rear axle is compensated, dictated by the installation of the vehicle.

In rezul1 / gate, wiping the kinematic scheme in space (Fig. 3) and spreading differential 5 in the crankcase of the gearbox 3 under the torque converter 1 provides compactness of the transmission monoblock, o6: i.e., its spacing, sp rear axle. With such an arrangement, the monoblock modules of the differential.1 practically do not increase the | -size of t | 1ans.mission and, in particular, the cross section), which is important when installing it directly between the rear wheels. The reduction of the horizontal size is also facilitated by the fact that in the gearbox pacno, iiar there is just a link of three f) coupling couplings in a row.

Due to the fact that the input from the idrotransformat (; pa to the box and transmissions of immersion in the middle part of its kinematic scheme to the console1) Nyu First Center) 15, is not a symmetrical (in opposite directions) position of the torque converter I OTHCKniie . ibHo other elements. With this input va. 1 17 remains short and tough.

The advantages of the previous transmission, as compared to the known transmissions, according to the traditional scheme, in relation to the field of large transmissions of my gearboxes, are the reduction of the dimensions of the main gear, the role of which is played by a gear pair 19 20, several times due to installation of the gearbox inlet at the gearbox, rear axle axle pulling and increase of the ground clearance under it due to removal of the main gear and differential from its internal cavity, exclusion of the most heavily loaded output cardan shaft, cha between Robot () transmission and main non-transmission, as well as the distribution of the output moment into two streams, at which ki} thematic links with the movers transmit lipyl but. yuvina K1) ut n1 moment

of the specified drive shaft, excluding the layout of the gearbox between the engine and transmission, a large number of steps with a small number of friction clutches, improved conditions of the engine, dynamics and fuel efficiency, simplicity compared with planetary transmissions due to the small number of n, channel ratios and increase reliability in comparison with purely valleys due to the installation of a shaft gearbox in the area of ma, the first is steeply of the first scalers.

Mode of operation facilitates the creation of hydromechanical transmissions in the field of large pugs, in which electric cars are used on manufactured cars. In particular, it does not require the development of a crunging gear, a gear unit, and as an output, xx, 1x with a mcp x 1300 liters. with.
