Accompanying drawing explanation
Fig. 1 is the structure principle chart of new-energy automobile flexible power drive system of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail detailed description.
With reference to Fig. 1, a kind of new-energy automobile flexible power drive system, by driving motor 1, torsion vibration absorber and variator 8
Composition, the driving disc spacing pressing 5 of torsional vibration damper is fixedly connected with driving motor output shaft 2 by inertial flywheel 3, torsional vibration damper from
Moving plate hub 6 is fixedly connected with the power shaft 7 of variator.
Described variator 8 can be electric control mechanical type automatic speed variator (EMT), it is also possible to be other types mechanical transmissions.
For loading the new-energy automobile of this device, in the process of moving, there are following four kinds of operating modes:
1. starting accelerating mode is when automobile by static, give it the gun by starting, true with GES by accelerator pedal signal
Fixed requested torque, through driving motor 1 to export, acts on inertial flywheel 3, and inertial flywheel 3 is by torsional vibration damper driving disc spacing pressing
5 act on damper spring 4, and damper spring 4 causes the disturbance moment of torsion of " surge " to decline further when being started to walk by new-energy automobile
Subtract, so that the jitter phenomenon of the torsion vibration natural frequencies of power train existence weakens, and then make car load longitudinal acceleration
Low frequency fluctuates widely and weakens further, and then power export the power shaft of EMT through the hub plate 6 of torsional vibration damper
7, export power transmission shaft until driving wheel through the output shaft of EMT8, make new-energy automobile more flat with accelerator in starting
Surely.
2. upshift operating mode: when new-energy automobile is in upshift, in the apparatus, power exports inertial flywheel 3 through driving motor,
Being delivered to torsional vibration damper driving disc spacing pressing 5 by inertial flywheel 3 makes it export through hub plate 6 through damper spring 4 power
EMT power shaft 7, in this transmittance process, " counter drag " active force driving motor effect is cut by vibroshock by driven gear
It is weak, so that " buffering " phenomenon that new-energy automobile occurs in EMT shifting up operation weakens.
3. downshift operating mode is when new-energy automobile is in downshift process, and in the apparatus, during downshift, power is through driving motor
1 is passed to inertial flywheel 3, is delivered to torsional vibration damper driving disc spacing pressing 5 by inertial flywheel 3, and vibroshock driving disc spacing pressing 5 is by power
Making it through hub plate 6 output to EMT power shaft 7 through damper spring 4, in this transmittance process, vibroshock is by driven
Gear mesh drives " delayed " active force of motor effect to weaken, so that new-energy automobile occurs in EMT shifting up operation
" delayed " phenomenon weaken.And then make downshift process, reduce impact, more smoothly gear shift.
4. disturbance encourages operating mode to travel, normal, moment of torsion excitation (torsional oscillation that such as road roughness causes) that is disturbed when automobile
Time, in the apparatus, when the disturbance by road surface encourages, disturbance excitation is passed to main reducing gear through wheel hub, through main reducing gear
It is passed to EMT, is passed to the hub plate of torsional vibration damper through the power shaft of EMT, make through the hub plate of torsional vibration damper
For vibroshock, thus disturbance excitation is weakened, remake for mass flywheel, thus act on driving motor.Reduction is disturbed
The dynamic excitation infringement to driving motor to cause.
The new of torsion vibration absorber is installed additional between motor and other types mechanical transmission or mechanical driving device for driving at loading
Energy automobile, in the process of moving, has the action and function of above-mentioned operating mode equally, its detailed description of the invention and aforesaid way class
Seemingly.
