P311 HYBRID TRANSAXLE
JDESCRIPTION
D The P311 hybrid transaxle is used on the '07 Camry Hybrid model.
D Containing a MG2 (Motor Generator No.2) for driving the vehicle and a MG1 (Motor Generator No.1)
for generating electrical power, this hybrid transaxle uses a continuously variable transmission mechanism
with compound gear unit (which consists of a motor speed reduction planetary gear unit and a power split
planetary gear unit) that achieve smooth and quiet operation.
D A transaxle damper that consists of a coil spring with low-twist characteristics is used in order to absorb
the torque fluctuation in the drive force of the engine.
D This transaxle uses two lubrication mechanisms concurrently: a lubrication mechanism consisting of a
trochoid type oil pump placed on the main shaft, and a lubrication mechanism consisting of an oil slinger
on the final gear. The concurrent use of the two mechanisms reduces the drive loss of the oil pump.
