General description of the gearbox (Skoda Favorit)

The transmission mechanisms are enclosed in a housing made of aluminum alloy, which is bolted to the left end of the engine. The transmission consists of a differential, main gear and gearbox.

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

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

The input and output shafts are located next to each other, parallel to the crankshaft and drive shafts, so that the teeth of their gears are in constant mesh. In the neutral position, the gears of the output shaft rotate freely on it, so that the drive cannot be transmitted to the driven gear of the main gear.

The gear shift is performed 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 makes the fork for engaging the desired gear move the synchronizer clutch connected to it along the shaft in order to engage the gear ring of the given gear with the synchronizer hub. Since the synchronizer hubs have a splined connection with the output shaft, the clutch of the hub with the gear ensures the connection of the gear with the shaft and, thus, transmits rotation. Synchronizers, providing a quick and smooth gear change, are installed on all forward gears. They consist of blocking rings, a hub equipped with spring-loaded crackers and a clutch.
