CHAPTER 4 8454
DIFFERENTIAL GEAR
• Differential gear is structured with four pin type.
• Differential gear is operated by sharing out suitable
revolution considering related conditions for the
wheels left and right to lead turning of the tractor
and traveling on curved or uneven road to be
smooth.
• A pin type deferential lock is mounted to stop the
differential function so not to allow just one wheel
to be slipped and moved considering of road sur-
face and pavement.
FINAL REDUCTION GEAR
• Planetary gear to transmit power transmitted from
the differential gear to the brake shaft (13 gear shaft)
to the rear axle as decelerated once again is ap-
plied to the final reduction gear.
• Internal gear mounted on the case is drawing revo-
lution power using planetary gear support (carrier)
with planetary gear thereon by driving the brake shaft
(linear gear).
• Since revolution force loaded on the rear axle of the
tractor is transmitted as divided to 3 planetary gears,
this planetary gear equipment is compact, excel-
lently endurable and capable of high deceleration
ratio without being much forced.
