The hydraulic of automatic transmission foundation changes quadrature implement
From;  Author:Stand originally

Hydraulic changes quadrature implement it is the necessary device on traditional and automatic gear-box, its action is the moment of force that changes engine output, and can slow down quickens concussion, make quicken more smooth-going. Can effective when shift gears reduce shift gears impact. Hydraulic is used to be twisted on car of turbine pressure boost implement the feeling that still can reduce turbine delay. Defect is: Because it uses hydraulic to deliver pitching moment, energy loss ratio is accordingly older, this also is one of reasons with oily bigger bad news of automatic gearshift car, it is to quicken next from time to tome arrearage, motivation comes so that use gearshift car without the hand fast.



The graph is now on the most commonly used hydraulic on automatic gearshift car changes quadrature implement, the hydraulic that this is dead function of lock of a belt changes be apart from implement. Main part has: Impeller, turbine, guide pulley, housing, input axis, take-off and clutch platen.

Impeller and input axis tigidity join, the motive force of engine is direct action at him, impeller rotates in working fluid, working fluid falls in the action of centrifugal force, move outwards by the axes of impeller, produce pressure difference thereby, powerful vortex is formed below the action with wrong pressure, the dynamical changeover with right now rotational engine became the backset that the liquid moves, eddy current drives the turbine that is linked together with take-off, it is turbine falls in the action of eddy current, rotate, right now, changeover of liquid kinetic energy became the kinetic energy that turbine rotates, output motivation via take-off thereby.



And because be to rely on liquid pressure,between this difference delivers kinetic energy, because this has very big energy loss, its energy delivers efficiency to be the energy of take-off and the ratio that input axial energy, accordingly, the rotate speed difference of turbine and impeller is less, energy loss is smaller, to reduce energy loss, guide pulley was decorated between turbine and impeller, the blue part in pursueing namely, guide pulley outfit is on the axis that is linked together with gear-box housing, contain between guide pulley and axis one-way surmount clutch, accordingly guide pulley can rotate toward a direction only, start in the car or reach when quickening (low speed travel) , the rotate speed difference that inputs axis and take-off is too big, energy loss is big, right now guide pulley falls in the action of one-way clutch, fixed go up in the axis, cannot turn, and the blade gift that must pass guide pulley to go up through the liquid of turbine regurgitate returns impeller, because the lamina on guide pulley becomes proper point of view, make the kinetic energy loss when liquid regurgitate is reduced somewhat. The rotate speed difference when impeller and turbine is very little (namely, normal travel / high speed travel) when, the one-way clutch on guide pulley is loose, make guide pulley OK flow along with liquid and rotate, also can reduce loss.
