Torque converter clutch. Hydrokinetic clutches are used in many modern cars, power transmission only due to fluid pressures, thus, without mechanically connecting the driver with the driven element. Such a clutch is equipped with:. in. car WINTER. The principle of operation of the torque converter: a ring-shaped rotor is mounted on the engine crankshaft, provided with straight, radially arranged blades, called a pump. Similar rotor, called a turbine, it is mounted on the driven shaft (clutch). Both rotors are built opposite to each other and tightly closed in a housing filled with 85-90% light mineral oil, a mixture of engine oil and kerosene (about 95% diesel) or vegetable oil.
When the engine is running, the pump rotates and the liquid between its blades, under the influence of centrifugal forces, is thrown against the turbine blades and exerts pressure on them, forcing the turbine to rotate following the pump. Only then does the clutch begin to transmit power, when the pressure of the liquid is strong enough, that is, at approx 600 pump rpm.
