We have seen a strong increase in automatic transmissions worldwide. And in recent years, the complexity of automatic transmissions has also increased steadily resulting in the increase in the number of gears too.
The cleanliness of the transmission oil has a significant impact on the service life of the individual components. If there is a high degree of contamination, these components are quickly damaged and no longer function.
There are suction and pressure filters: Suction filters directly protect the pump, and pressure filters directly protect the hydraulic actuators and usually filter only part of the oil. If the design is poor, the filter will be bypassed during a wide range of operating conditions. As a result, a great deal of unfiltered oil reaches the individual components.
In order to avoid this, our development focus is on filtration concepts that significantly reduce unfiltered oil.
