Level deceleration driving gear 42, is transferred to the second reduction driven gear 31 engaged with double reduction driving gear 42 by power, the
Two reduction driven gear 31 drive differential mechanism 4, and through differential mechanism 4, power finally reaches wheel, it is provided that driving force.
During whole power transmits, main pyrotoxin is that electric current passes through electric energy conversion in the second motor stator 8
Heat energy, and the frictional heat of geared portions.Therefore, in order to the second motor stator 8 is cooled down, back casing 12 collects
Becoming to have cooling water channel, the cooling of gear is then by traditional gear box oil splash lubrication and cooling.In order to ensure to have height
The security reliability of the second motor stator 8 insulation of piezoelectricity, back casing 12 is divided into the dry chamber of the second motor and running part
Wet chamber, is sealed by the second electric engine oil seal 15 between dry and wet chamber, and opens oilhole on the second motor shaft 16, ensures to be arranged in the
The second electric engine oil seal 15 on rear side of two motor fore bearings 14 has enough oil lubrications and not ablation was lost efficacy.
Second rotor 13 and the second motor shaft 16 be connected by first half interference fit, latter half gap
The connected mode of spline fitted, before and after the second rotor 13, axial location is second motor shaft 16 shaft shoulder and the second electricity respectively
Machine rear bearing 11.This benefit connecting location is both can to have ensured the highest of the second rotor 13 requirement by interference fit
Alignment degree, can reliably transmit moment of torsion by spline again.
Power coupling case combustion engine powered incoming by the first motor 5 side, the first rotor 36 and internal combustion engine
Bent axle is bolted.When using series model, combustion engine powered being used for generates electricity completely, and now gearshift hangs over neutral
On, internal combustion engine drags the first rotor 36 and rotates, and produces electric current by electromagnetic induction, for power in the first motor stator 35
Battery charges.When using combustion engine powered direct driving vehicle, power coupling case provides two grades of double reductions to increase torsion machine for it
Structure, the primary speed-down gear train of one of them gear and the second motor output train of reduction gears share, the one-level of another gear
The driving gear of gear train that is first train of reduction gears is the first deceleration driving gear 24, and driven gear is the first reduction driven tooth
Wheel 28.Wherein the first deceleration driving gear 24 is arranged on reducing gear power shaft 27, this gear and reducing gear power shaft 27
Between have needle bearing 25 ensure when gear motor output train of reduction gears when both relative motion；Two gears
Primary speed-down gear is installed on jackshaft, and gear is connected by spline with axle；The driving gear of the second train of reduction gears with
Jackshaft 30 is integral type structure, and driven gear is the second reduction driven gear 31, the second reduction driven gear 31 and differential mechanism
Shell 32 is bolted, and all above travelling gear is helical gear, while the requirement of strength when meeting big load also
Can there is less meshing noise.Combustion engine powered can be transmitted by below scheme: bent axle → the first rotor 36 → subtract
Speed mechanism power shaft 27 → the first deceleration driving gear 24 → the first reduction driven gear 28 → jackshaft 30 → the second reducing gear
Wheels → differential mechanism 4 → wheel.The power on/off that can control the first motor 5 while combustion engine powered driving vehicle determines
The need of for power battery charging while IC engine-powered vehicles.
During combustion engine powered transmission, main pyrotoxin is that electric current is turned by electric energy in the first motor stator 35
The heat energy changed, and the frictional heat of geared portions.Therefore, in order to the first motor stator 35 is cooled down, procapsid 34
On be integrated with cooling water channel, the cooling of gear is then by traditional gear box oil splash lubrication and cooling.In order to ensure to gather around
Having the security reliability of the first motor stator 35 insulation of high-tension electricity, procapsid 34 is divided into dry chamber and the driving section of the second motor
The wet chamber divided, is sealed by the first electric engine oil seal 38 between dry and wet chamber, and opens oilhole on reducing gear power shaft 27, ensure
It is arranged in that the first electric engine oil seal 38 on front side of jackshaft fore bearing 29 has enough oil lubrications and not ablation was lost efficacy.
Under nominal situation, such as Fig. 4, the first rotor 36 self can be that power transmission chain below sponges from internal combustion engine
Vibration.When the vibrational state of the internal combustion engine that power coupling case is mated is excessively severe, it is also possible to couple in the first motor
Torsional damping arrangement, as shown in Figure 5: external diameter and first rotor 36 of damper mechanism 37 are bolted, internal diameter is by flower
Key is connected with reducing gear power shaft 27.During the vibration noise ensureing power coupling case, the foot needed for damper mechanism 37
Enough rotary inertias are provided by the first rotor 36, so that sends out the first rotor 36 and damper mechanism 37 couples knot
Structure realizes the function of flywheel in orthodox car power transmission chain.
Second motor shaft 16 is also equipped with transmit moment of torsion by woodruff key, by second motor shaft 16 shaft shoulder and the second electricity
The parking gear 17 of machine fore bearing 14 location, outside halting mechanism pins the second motor shaft 16 by parking gear 17, by the
Two motor output train of reduction gears, the second train of reduction gears and the transmission of differential mechanism, pin wheel, thus realize parking merit
Energy.
