General description of the gearbox

The transmission mechanisms are enclosed in an aluminum alloy crankcase that is bolted to the left end of the engine. The transmission consists of a differential. main gear and gearbox.

Drive is transmitted from the crankshaft through a friction disc to the transmission input shaft, which rotates on sealed ball bearings. From the input shaft, the torque is transmitted to the output shaft of the transmission, which rotates on a roller bearing (right end) and sealed ball bearing (left shaft end).

From the output shaft, the drive is transmitted to the driven gear of the main gear, rotating in the differential housing, which, in turn, transmits it to the satellites and then to the side gears of the differential and drive shafts. When turning, the rotation of the pinion gears on their shaft allows the inner wheel of the car to rotate more slowly than the outer one.

The input and output shafts are side by side, parallel to the crankshaft and drive shafts, so that their gear teeth are in constant mesh. In the neutral position, the gears of the output shaft turn freely on it so that the drive cannot be transferred to the driven gear of the final drive.

Gear shifting is carried out by means of a lever installed in the floor of the passenger compartment, connected by a rod to the gear selection mechanism on the transmission. The gear selection mechanism causes the selector fork of the desired gear to move along the shaft of the synchronizer clutch associated with it in order to engage the gear ring of this gear with the synchronizer hub. Since the synchronizer hubs have a splined connection to the output shaft. the clutch of the hub with the gear ensures the connection of the gear with the shaft and. thus transmitting rotation. Synchronizers for fast and smooth gear changes are installed in all forward gears. They consist of locking rings, a hub fitted with spring-loaded crackers and a coupling.
