5.3.6 Torque converter and fluid coupling
However, the designers made a decision not to stop there and decided that it was necessary to expand the capabilities of the torque converter in order to improve its adaptability to various operating modes. The solution was simple and interesting at the same time. They installed the reactor wheel on the freewheel clutch, making it possible for the torque converter to work in the hydraulic clutch mode. Such torque converters are called complex.
Note
A freewheel clutch (another name - "overrunning clutch") is a unit, which, under certain conditions, excludes the transfer of torque from the driven shaft back to the driving shaft if, for any reason, the driven shaft starts rotating faster. The most vivid example is the drive of the drive wheel in a bicycle: when you need it, you rotate the pedals - and the thrust from them is transmitted to the wheel through the clutch. Then after accelerating, you stop doing hard work - you do not rotate the pedals, and the wheel rolls along the road without problems. Another example: a wrench with a "ratchet". In one direction it is locked and tightens the bolt, but during the return stroke, the head of the wrench remains in place, and the handle returns to its original position with a characteristic crackle.
