Embodiment
As shown in the figure, a kind of fluid torque converter that carries out flexible latch control, comprise torque-converters housing 1, output shaft 2, driving gear 3, pump impeller 4, hubcap 5, turbine 6, guide wheel 7, wheel stand 20, free wheel device 8 and lockup clutch, wheel stand 20 is connected and fixed with torque-converters housing (1), free wheel device 8 is arranged on guide wheel 7 inside, be connected with guide wheel 7 and wheel stand 20 respectively, described hubcap 5 is fixedly connected with pump impeller 4, pump impeller 4 is fixedly connected with driving gear 3, and the external toothing 9 of turbine 6 and lockup clutch is fixedly connected with output shaft 2.The output terminal of described fluid torque converter is provided with three power taking mouths 10, power taking mouth 10 includes power take-off gear 11, the driving gear 3 of fluid torque converter is meshed respectively at the power take-off gear 11 of three power taking mouths 10, in described lockup clutch, be provided with proportional control solenoid valve 12, fluid enters proportional control solenoid valve 12 by the filler opening of lockup clutch, and the fluid that proportional control solenoid valve 12 exports enters in hubcap 5 by the oil duct of output shaft 2 and the axis of guide.Described hubcap 5 is in transmission connection by driving ring 13 with engine flywheel, and pump impeller 4 is fixedly connected with hubcap 5.
For improving the fuel economy of motor, described fluid torque converter is also provided with the lockup clutch that proportional control solenoid valve 12 is controlled, for when the vehicle start of the increase torsional interaction except utilizing torque-converters, climbing or the low-speed heave-load operation etc. time, can control lockup clutch combination by passing ratio control solenoid valve 12, vehicle is moved in locking operating mode.Because lockup clutch is arranged on hubcap 5 inside, lockup clutch in conjunction with after hubcap 5, pump impeller 4, turbine 6 directly can be linked together, torque converter output shaft 2 directly with the rotation of motor one, reach the effect of raising transmission efficiency.Can control by the open degree of control ratio solenoid valve combination time and the cohesive process of lockup clutch, play and reduce the vibration that locking moment produces, improve the object of the travelling comfort of driving simultaneously.
For reducing the heating of oil that stirs of fluid torque converter inside, the guide wheel inside of described fluid torque converter is also provided with free wheel device 8, for in the time of torque converter locking, and in the time that the rotating speed of pump impeller 4 and turbine 6 is identical, when guide wheel 7 can freely be rotated, reduce the heating of oil that stirs of guide wheel 7, thereby improve transmission efficiency; For when vehicle start, climbing or the low-speed heave-load operation etc. time, make guide wheel 7 fixing, thereby increase the output torque of torque-converters simultaneously, play the effect of bending moment.
Described fluid torque converter hydraulic oil enters into the oil duct of wheel stand 20 by the filler opening A of torque-converters housing 1, then enters into the oil duct of pump impeller wheel hub 19, finally enters into the blade of pump impeller 4; Pump impeller 4 is fixed together with hubcap 5, and engine flywheel passes to hubcap 5 by power by driving ring 13, thereby passes to pump impeller 4.Hydraulic oil is because the rotation of pump impeller 4 is delivered to hydraulic oil by the blade of pump impeller 4 the circulate circle position of hubcap 5, hydraulic oil flow in the blade of turbine 6 through the circulate circle of hubcap 5, thereby hydraulic oil promotes the blade of turbine 6, power is passed to turbine 6 from pump impeller 4; Turbine 6 is connected on output shaft 2 together with lockup clutch external toothing 9, thereby outputs power to speed changer.
When the direction of blade rotary that promotes guide wheel 7 when hydraulic oil is counterclockwise, guide wheel 7 is because free wheel device 8 is counterclockwise for fixing, cause guide wheel 7 and wheel stand 20 to be fixed in torque-converters housing 1, hydraulic oil out impacts guide wheel 7 from the blade of turbine 6, because guide wheel 7 is fixing, hydraulic oil is impulse turbine 6 conversely, the output torque of turbine 6 is greater than the input torque of pump impeller 4, thereby play the effect that increases output torque, now torque-converters is in bending moment operating mode, the circulate circle diameter of fluid torque converter provided by the present invention is 420 ~ 440mm, peak efficiency under bending moment operating mode reaches 84% ~ 86%, torque ratio maximum reaches 2.3 ~ 2.5, under locking operating mode, transmission efficiency can reach 96% ~ 99%,
In the time that the rotating speed of turbine 6 is identical with the rotating speed of pump impeller 4, the direction of impacting guide wheel 7 blades from turbine 6 blades hydraulic oil is out that free wheel device 8 clockwise directions are freely to rotate clockwise, thereby drives guide wheel 7 freely to rotate; Now guide wheel 7 is due to free rotation, cause to stir heating of oil little; This operating mode is the coupling operating mode of torque-converters, and under coupling operating mode, torque-converters transmission efficiency can improve greatly.
When fluid enters into proportional control solenoid valve 12 from lockup clutch import D, by the size of control ratio solenoid valve opening E, control pressure and the flow of fluid.From E, fluid is out through proportional electromagnetic valve oil outlet F, the B mouth that enters into output shaft, enters into the axis of guide 18 by the oil channel hole of output shaft 2, while finally entering into hubcap 5, fluid can promote piston 16, and piston 16 and friction plate 15, antithesis sheet 14, platen 17 are pressed together; Now hubcap 5 is fixed together with friction plate 15, antithesis sheet 14, piston 16, platen 17, lockup clutch external toothing 9, turbine 6, output shaft 2, and output shaft and engine direct connect in succession, and this operating mode is locking operating mode; Under locking operating mode, turbine 6 is identical with pump impeller 4 rotating speeds, makes the fluid pumping from turbine blade that guide wheel is freely rotated clockwise, thereby reduces the heating of oil that stirs of torque-converters inside, improves the efficiency of transmitting; The lockup clutch of described fluid torque converter can passing ratio solenoid valve control control the size of E mouth, thereby control combination time and the cohesive process of lockup clutch, be able to reduce the impact that locking moment produces, improve driving comfortability.
The output terminal of described fluid torque converter is provided with 3 power taking mouths 10, and its inner power transmission is: driving gear 14 is fixed together with pump impeller 4, and is connected on the flywheel of motor with hubcap 5, driving ring 13 together.Thereby by the transmission of power of motor to driving gear 14, driving gear 14 engages with 3 power take-off gears 13 respectively, thereby power is divided into 3 power, power taking mouth is arranged on torque-converters housing, shorten Transmitted chains, in arrangement, reduce the transfer case equipment that uses, when shortening Transmitted chains, reduce vehicle cost.
