The bands are tightened round the ring equipment to circumvent it turning, plus the clutches are accustomed to lock the Sunlight gear and planets.
Clutch System After you utilize both clutch, an annular piston forces The 2 sets of clutch discs into Call. Therefore, it can make them revolve together as an individual locked device. The oil tension, provided thru’ controls, operates the piston and functions to be a tension plate in a mechanical clutch. The clutch application locks the sun gear as well as planet cage from the front unit.

The central reactor converts this turning effort by redirecting the stream of fluid back into the impeller to give better torque at minimal speeds.
For many regular autos, availability and previous expertise finally establish gearbox choice. Take a look at drives help determine what fits specific needs before committing to both shifting style.
At minimal revs the reactor is stationary and deflects the oil back towards the impeller. This increases the torque applied to the turbine.
