  1. Hybrid Transaxle

  2. Hybrid Transaxle • Overview • P112 type • Components: • MG (Motor Generator) 1 • MG (Motor Generator) 2 • Power-dividing Mechanism (Planetary Gears) • Reduction Mechanism • Differential Mechanism • Fluid type: ATF WS • Capacity: 3.8 liters

  3. Hybrid Transaxle • Overview • P112 type Chain-drive Sprocket Planetary Gears MG2 MG1

  4. Hybrid Transaxle • Overview • P112 type Counter Drive Gear Chain-driven Sprocket Counter-driven Gear Reduction Mechanism Final Drive Pinion Gear Final Ring Gear Differential Mechanism

  5. Hybrid Transaxle • MG1 / MG2 • Compact and lightweight, highly efficient AC500V motor generator MG2 MG1

  6. Hybrid Transaxle • MG1 • Main operations  Generator • When engine starting  Starter Stator Coil MG1 Rotor Speed Sensor

  7. Hybrid Transaxle • MG2 • When driving  Main power to engine power (Starting off) or provides supplementary • When braking  Converts kinetic energy to electrical energy MG2 Stator Coil Rotor Speed Sensor

  8. Hybrid Transaxle • MG1 / MG2 • Specifications

  9. Hybrid Transaxle • MG1 / MG2 • MG1 / MG2 include stator coil, permanent magnet Stator Coil Permanent Magnet (Rotor)

  10. Hybrid Transaxle • MG1 / MG2 • MG1 / MG2 rotate via 3-phase alternating current

  11. N S Hybrid Transaxle • MG1 / MG2 • Stator coil polarity and magnetic strength changes moment by moment

  12. N S Hybrid Transaxle • MG1 / MG2 • Rotor of permanent magnet is rotated via attraction / repulsion from stator coil

  13. N S Hybrid Transaxle • MG1 / MG2

  14. N S Hybrid Transaxle • MG1 / MG2

  15. Hybrid Transaxle • Speed Sensor (Resolver) • Detects position, speed and direction of MG1 / MG2 rotors Speed Sensor (for MG2) Speed Sensor (for MG1)

  16. Hybrid Transaxle • Speed Sensor (Resolver) • Comparing the S and C waveforms against the excitation coil reference waveform Rotor Excitation Coil -S -C +C +S S +S +C -C -S C Excitation Coil Manual Auto

  17. Hybrid Transaxle • Transaxle Damper • Installed at location of conventional clutch Reduces shock which occurs when kinetic energy is transmitted

  18. Reservoir Pump MG1 / 2 Radiator Inverter Hybrid Transaxle • Cooling System • Cooling circuit is used for both MG1 / MG2 • Separate cooling system from engine Reservoir Tank Electric Water Pump Radiator

  19. Hybrid Transaxle • Oil Pump • Forced lubrication system via trochoid pump used to lubricate main shaft bearings • Oil pump functions when engine is being driven Oil Pump
