4. Differential Gear Unit
For the differential gear unit, a 2-pinion type that is similar to the differential unit of the conventional
transaxle is used.
5. Transaxle Damper
A transaxle damper that consists of 4 coil springs with low-twist characteristics is used in order to absorb the
torque fluctuation in the drive force of the engine. Furthermore, a torque fluctuation absorbing mechanism
that uses a dry-type, single-plate friction material is used. Through the use of the parts, a damper construction
that excels in absorbing the vibrations of the engine motive force has been achieved.
6. MG1 and MG2
MG1 and MG2 are located coaxially at each end of the compound gear unit.
MG1 connects to the sun gear of the power split planetary gear, and MG2 connects to the sun gear of the motor
speed reduction planetary gear. For detailed characteristics of MG1 and MG2, refer to MG1 and MG2 in
THS II, on page TH-19.
Service Tip
Do not disassemble MG1 or MG2 because they are precision components. If a malfunction is found
on either of these components, replace MG1 or MG2 as a complete assembly.
