Engine power is transmitted through the clutch to the drive shaft of the gearbox. This drive shaft has 5 or 6 gears (gears), including reverse, which are constantly engaged with the corresponding gears of the so-called driven shaft. These gears can rotate freely until one of them, when a certain gear is engaged, connects with the corresponding gear on the drive shaft. The ratio of the number of teeth of the corresponding pair of gears is the gear ratio.
At "Volkswagen" fully synchronized forward gears. The gears of the driven and driving shafts are located on the rollers ("needles"). Thus, there is no rigid connection between the shafts and gears. Gears are always engaged. When the gear is engaged, a connection is made between the gear and the shaft. In order to match the number of revolutions of the shaft and the gear, it is possible to slide the shaft in relation to the gear through the friction elements of the synchronizer. Due to friction, the gear slows down until its revolutions equalize with the revolutions of the shaft, after which it is possible to rigidly connect the gear to the shaft through a synchronizer, i.e. enable transmission.
Switching problems
If there are difficulties during switching, you should check whether any parts in the switching wire are bent, whether all bearing bushings are in order.
