b. Operation Principle of the Rear Differential
Gear
Power is transmitted from spiral bevel pinion (1) via 39
spiral bevel gear (2) and through differential gear as-
sembly (3) to 13 gear shaft (4).
13 gear shaft (4) is engaged with the gears of plan-
etary gear assembly (5). Planetary gears are operated
in 68 internal gear (10). Consequently, power trans-
mitted to 13 gear shaft (4) is transmitted to rear axle (6)
via planetary gear assembly (5).
Differential gear assembly (3) is composed of two def-
erential side gear (7) and four differential pinion (8) in
the differential case.
