6.2.1. Features of a design
On the Chery Amulet cars assembled at the Kaliningrad enterprise "Avtotor", establish a mechanical transmission of the AQO15AA type.
|Fig. 6.4. Transmission: 1–back cover of a transmission; 2–sensor of speed; 3–switch of light of a backing; 4–gear shifting lever; 5–сапун; 6–intermediate draft of a choice of transfers; 7–semi-axis epiploon; 8–right semi-axis; 9–left semi-axis; 10-an opening stopper for oil filling; 11-cap of a back cover of a transmission; 12-lever of switching off of coupling; 13-transmission case; 14-coupling case
The mechanical transmission is executed according to the dvukhvalny scheme with five synchronized transfers of a forward course. The transmission and the main transfer with differential have the general case 13 (fig. 6.4)
and 5 (fig. 6.5). The case of coupling is attached to a forward part of a case of a transmission 14 (see fig. 6.4
) and 3 (see fig. 6.5). On a back part of a case of a transmission the aluminum cast cover 1 (see fig. 6.4
) and 6 (see fig. 6.5) is established.

On primary to a shaft 4 (see fig. 6.5) gear wheels of III, IV and V transfers rotating on needle bearings with the synchronizers established on shlitsa of a shaft are located, and leading gear wheels of I, II transfers and a backing are made for a single whole with primary shaft.
The secondary shaft 2 is made together with a leading gear wheel of the main transfer 1, besides on a shaft slidings freely rotating on bearings conducted gear wheels of I and II transfers with the synchronizer established on shlitsa of a shaft, and fixed on shlitsa of a shaft conducted gear wheels of III, IV and V transfers are established.
Transfers of a forward course join axial moving of couplings of the synchronizer I-II of the transfers established on secondary shaft, and synchronizers III-IV of transfers and the V transfer, established on primary to shaft. The mechanism of gear shifting is located in a transmission case in its top part. Outside there is a lever 4 (see fig. 6.4
) a choice and the gear shifting, the 6th choice of transfers connected by intermediate draft with the lever mechanism of a drive of the gear shifting, established on a case of the steering mechanism.
The drive of management of a transmission consists of the coulisse of the lever of gear shifting with the spherical support established on the basis of a body...
... systems of drafts and the levers established on a case of the steering mechanism, and the mechanism established in a case of a transmission.
The main transfer is executed in the form of pair of the cylindrical gear wheels which have been picked up for noise. The torque is transferred from a conducted gear wheel of the main transfer to differential and further on drives of forward wheels.
Differential conic, two-satellite. Tightness of connection of semi-axes 8 and 9 (see fig. 6.4
) with gear wheels of differential is provided with epiploons 7.
Feature of a transmission of the Chery Amulet car — located in a box case the bearing 8 (see fig. 6.5) the coupling switching off, influencing on a podpyatnik of a diafragmenny spring of a press disk of coupling through a rod 7 established in a hollow primary shaft 4.
