General description of the mechanical box

The transmission is housed in an aluminum alloy housing bolted to the left end of the engine and consists of a final drive differential and gearbox. The gearbox is designed to select the gear ratio that is most suitable for a particular engine operating mode and vehicle load. There are five forward gears, one reverse and a neutral position. The differential is connected to the wheels.

Rotation is transmitted from the crankshaft through the clutch to the input shaft, which rotates in needle bearings and has an extension on one side. A friction clutch disc is installed on the extension.

From the input shaft, rotation is transmitted to the driven shaft, which rotates in tapered roller bearings, and then to the differential crown wheel. It rotates with a differential housing and planetary gears. thus driving the sun gears and drive shafts. The rotation of the planetary gears on their shafts allows the inner wheel to rotate at a slower speed than the outer wheel when the car is cornering.

The input and driven wools stand side by side, parallel to the crankshaft and drive shafts, so that the gear teeth of the mechanism are in constant mesh. In the neutral position, the gears of the mechanism rotate freely on needle bearings or bushings; rotation is not transmitted from the input shaft.

When the driver selects a gear, the selector mechanism will move the synchronizer sleeve along the shaft with the appropriate fork until the transmission gear engages with the synchronizer core. Since the cores are synchronous, rotation is transmitted to the shaft through synchronizers. A synchronization system in the gearbox is available on all forward gears, consisting of locking rings, spacer springs and/or displacement inserts.
