2.2 Torque converter
The torque converter consists of pump wheel installed on input shaft, a turbine
wheel installed on output shaft and stator wheel fixed on torque converter body.
Pump rotor is driven by elastic plate, the elastic plate is connected with flywheel,
the pump rotor start turning while the engine is running. The liquid in pump rotor eject
along blade lattice. The mechanical energy changes to kinetic energy.
So the liquid feed into vane of turbo, and transfer the moment to output shaft, the
direction that the liquid leave turbo change under the action of idler pulley, and the liquid
flow into pump rotor with the best angle, it produce counterforce moment to push the
idler pulley and the output shaft add a moment which is equal to the counterforce
moment
When the turbo rotate speed increase and near to input rotate speed, the change of
liquid angle reduce, the moment of output reduce to it, finally, the liquid flow into idler
pulley in the reverse direction, and then the above counterforce moment act backward.
Under the circumstance, the torque from output shaft is less than the input shaft's. To
prevent the phenomenal, there is a unilateralism clutch installed in idler pulley, when the
counterforce moment act backward, the idler pulley running freely, under the
circumstance, the input torque is equal to output torque, and ensure work efficiently.
The torque converter changes the transfer of moment by mechanic method, and
has coupling mechanism and torque converter function, so it' is two phase, operate
swiftly and raise efficiency.
There are unilateralism clutch, turbo, pump rotor and idler pulley installed in torque
converter. The torque converter is full of oil.
On pump wheel end, there is a gear engaged with the drive gear of charging pump
to drive changing pump.
The turbine wheel is connected with input shaft by spine, transfer power to
hydraulic clutch.
The structure of the torque converter refers to Fig.2-2.
