The hydraulic automatic speed variator of clutch-clutch fluid power automatic transmission and traditional overrunning clutch compares that simplicity of design, volume are little, light weight, cost are low, develops rapidly at last decade.But clutch-clutch fluid power automatic transmission has been cancelled the overrunning clutch of traditional hydraulic automatic speed variator, when obtaining above advantage, also makes the control of itself become complicated more.In order in competition, to stand on the invincible position with traditional hydraulic automatic speed variator; Clutch-clutch fluid power automatic transmission just need reach the shift quality identical with traditional hydraulic automatic speed variator through accurately coordinating the action that cut-off clutch and clutch to be joined are treated in control.
Clutch-clutch-type hydraulic automatic speed variator mainly is through the separation of at least two electromagnetic valve respective clutch and joint.Separation and joint rule through rational solenoidoperated cluthes so that reduce shift impact, shorten the gearshift time, reduce the clutch slipping merit, prolong life of clutch.
The timing controlled of two clutches of shift process is most important.If cut-off clutch does not separate, combined to cause the two retainings of extension in conjunction with clutch, cause very big shift impact, may make speed changer produce serious consequence in addition; If cut-off clutch separates fully, do not combine in conjunction with clutch, will cause the shift process power interruption.Yet,, be difficult to obtain the oil pressure characteristic and the volume characteristic of hydraulic type automatic transmission according to design because hydraulic type automatic transmission oil circuit is complicated.Confirm the oil pressure and the volume characteristic of hydraulic type automatic transmission so need rating test.
