Previously, “in another life”, when we talked about a robot gearbox, in 90% of cases we meant the DSG transmission used on cars of car brands from the Volkswagen AG family. Recently, Russian motorists were confronted with the fact that almost the majority of Chinese passenger models, which are methodically conquering the Russian market, are also equipped with “robots”. This trend will soon lead to this type of CP becoming dominant in Russia.
At least on more or less new cars. Accordingly, more and more car owners will need to learn how to properly maintain them. To begin with, let’s say that the frequency of oil changes in the gearbox of “robots” is prescribed in the operating instructions for each car. As a rule, we are talking about synthetic (in extreme cases semi-synthetic) lubricants with a viscosity of 75W-80 and a class not lower than GL-4. These are fairly common liquids. These are also used in manual transmissions. After all, a ‘robot’ is, as you know, structurally just an automated ‘mechanic’.
In modern cars, robotic gearboxes with a double disc clutch are used in the vast majority of cases. This can be ‘dry’ or ‘wet’.
With a “wet” clutch, the discs are immersed in oil. This circulates through the gearbox and also lubricates the gears. In this case, the lubricant gradually becomes clogged with wear products from both the discs and gears.
