The Active On-demand Coupling (AOC) can be described as a hydraulic pump.
The basic pressure is generated by the electronic feed pump. This pressurizes the annular pistons with oil so that they are pressed against the cam disc
via rollers. The annular piston generates a working pressure which is led to the operating piston via the pressure valve. This pressure creates a fixed
connection between the input and output shafts. The maximum pressure is limited by the pressure limiting valve. The difference in speed between the
input and output shafts is in proportion to the oil pressure fed to the annular pistons. A large difference between the input and output shafts results in
