Input shaft 29 (pic. 5.2) The gearbox is made in the form of a block of driving gears, which are in constant engagement with the driven gears of all forward gears. The secondary shaft 25 is hollow, with a removable drive gear 3 of the main gear. On the secondary shaft of the gearbox are driven gears 16, 18, 19, 21, 23 and synchronizers 17, 20, 24 forward gears. The front bearings 4, 31 of the shaft are roller, the rear 22, 28 are ball bearings. An oil sump 5 is located under the front bearing of the output shaft of the gearbox, directing the oil flow into the output shaft and further under the driven gears.
Double satellite differential. The preload in the differential bearings is adjusted by selecting the thickness of the ring 13. The driven gear 12 of the final drive is attached to the flange of the differential box. On one of the trunnions of the differential box, a master ring 7 of the magnetoelectric speed sensor is installed.
The gearbox control drive consists of a lever 11 (pic. 5.3) gear change, ball joint, thrust 10 and gear selection mechanism (installed in the gearbox housing). In order to exclude spontaneous disengagement of gears due to axial movement of the power unit on its supports while the Lada Kalina car is moving, a jet thrust 19 is introduced into the gearbox control drive, one end of which is connected to the power unit, and a body 7 of the ball bearing of the lever is attached to the other end gear shifting.
The reverse gear lock is controlled by a solenoid mounted on the gearbox housing, which, in turn, is controlled by a switch 13 mounted on the gear lever 11.
On a Lada Kalina car, the gear selection mechanism is made as a separate unit and is attached to the plane of the clutch housing inside the gearbox.
In building 9 (pic. 5.4) gear selection mechanism fixed two axles. A three-arm gear selection lever 2 and two locking brackets 7 and 11 are installed on axle 3. Another axle 1 passes through the holes of the locking brackets, fixing them from turning. Shoulder b three-arm lever 2 is used to engage forward gears, the lever A - to turn on the reverse gear, and the lever of the gear selection rod connected through the cardan joint with the rod 10 acts on the third arm (see fig. 5.3) gearbox control drive. On axis 6 (see fig. 5.4) fork 8 for reverse gear is installed. The gearbox is filled with gear oil, the level of which should be between the check marks on the oil level indicator.
