Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, it is to be understood that protection scope of the present invention is not by the restriction of detailed description of the invention。
Explicitly indicate that unless otherwise other, otherwise in entire disclosure and claims, term " includes " or its conversion will be understood to comprise the element or ingredient stated at such as " comprising " or " including " etc., and does not get rid of other element or other ingredient。
As in figure 2 it is shown, the concrete structure according to the driving structure of the vehicle of the specific embodiment of the invention includes: the control circuit of direct current generator 4, fluid torque-converter 5, change speed gear box 6 and this direct current generator 4。Wherein, direct current generator 4 is separately excited machine, and it is as the driving device of car load, by the ride comfort connecting realization starting and gearshift of fluid torque-converter。Torque characteristics due to separately excited DC machine: Motor torque and the direct correlation of DC current。The moment of torsion bigger in order to obtain motor, can realize the size of regulating loop electric current by the resistance that the slide rheostat of regulable control circuit is different thus realizing controlling the size of the moment of torsion of direct current generator。The driving structure of this vehicle adopts direct current generator and fluid torque-converter to substitute the drive mechanism of traditional internal combustion engine and clutch, possesses the feature that low speed torque is big, the sound is little, temperature is low so that the dynamic property of vehicle, disguise, smooth-going performance will be better than traditional drive mechanism；And the control of the moment of torsion of direct current generator, rotating speed is to be controlled by the size of adjustment slide rheostat, the performance of electromagnetism interference is high, it is possible to adapt to special, complicated electromagnetic environment。
Specifically, direct current generator 4 is separately excited machine, and it is as the driving device of car load。Direct current generator is divided into self-excitation and separate excitation, and separately excited machine refers to that the magnet exciting coil of motor and armature winding separate, and exciting current individually provides, unrelated with armature supply。Separately excited machine is easy to control, it is easy to realize speed governing, and controller control rotating need not be installed switching contactor and is generally widely used in electri forklift, electric automobile, electric sightseeing vehicle, electrically propelled traction vehicle。
The hydrodynamic unit that fluid torque-converter 5 (FluidTorqueConverter) is made up of pump impeller, turbine, guide wheel。It is arranged between electromotor and variator, with hydraulic oil (ATF) for working media, plays the effect of transmission torque, bending moment, speed change and clutch。The non-rigid torque converter of one that fluid torque-converter is working media with liquid, is one of the form of hydraulic power。It has an airtight working chamber, and liquid flows at cavity circulation, and wherein pump impeller, turbine and guide wheel are connected with power shaft, output shaft and housing respectively。When engine (internal combustion engine, motor etc.) band driven input shaft rotates, liquid flows out from centrifugal pump wheel, returns again to pump impeller sequentially through turbine, guide wheel, circulates again and again。The mechanical energy of power shaft is passed to liquid by pump impeller。High-speed liquid promotes turbine to rotate, and energy is passed to output shaft。Fluid torque-converter transmits moment of torsion by liquid with the change that blade interaction produces the moment of momentum。Fluid torque-converter is different from being mainly characterized by it and having fixing guide wheel of fluid coupling。The guide functions of liquid is made the output moment of torsion of fluid torque-converter higher or lower than input torque, thus can be called torque-converters by guide wheel。The ratio of output moment of torsion and input torque claims torque ratio, and output speed is zero-speed torque ratio when zero normally about 2～6。Torque ratio declines with the rising of output speed。The power shaft of fluid torque-converter and output between centers, by liquid communication, do not have rigid attachment between working component。The feature of fluid torque-converter is: can eliminate shock and vibration, overload protection performance and starting performance good；The rotating speed of output shaft can more than or less than the rotating speed of power shaft, and the speed discrepancy of two axles is different with the size of transmission moment of torsion；Having good fluid drive performance, when load increases, output speed declines automatically, otherwise automatically rises；Ensureing that engine has stable working area, the transient changing of load is substantially without in reflection to engine。Fluid torque-converter efficiency near declared working condition is higher, and peak efficiency is 85%～92%。Impeller is the core of fluid torque-converter。The shape of its pattern and position and blade, has decisive action to the performance of torque-converters。Some fluid torque-converters have plural turbine, guide wheel or pump impeller, so as to obtaining different performances。It is most commonly that rotating forward (output shaft is consistent with steering input shaft), single-stage (only one of which turbine) fluid torque-converter。What have torque-converters and coupler performance feature concurrently is called converter coupling, for instance the fluid torque-converter that guide wheel can be fixed, can also rotate with pump impeller。For making fluid torque-converter normal operation, it is to avoid produce cavitation erosion and ensure heat radiation, it is desirable to have the AFS Auxiliary Fuel Supply System of certain charge oil pressure and cooling system。Preferably, fluid torque-converter 5 is non-permeable fluid torque-converter。
