Chapter 5 .Transmission
SECTION 1.GENERAL DESCRIPTION
1. WHEEL DRIVE SYSTEM
The wheel driving system is composed of the following major components:
Transmission
Space transmission
Front transmission
Main Change gears
Sub-change gears (speed range)
Front drive change gears
Reverse change gears
(Linear shift mechanism)
Rear transmission
Ring gear
Differentials
Dif-lock
Fig.5-1 Wheel drive system
1) The standard transmission produces 12 speeds forward and reverse :F1 and R1 by reverse
change gears;4 speeds by main change gears;3 speed by sub-change gears.
2) Synchromesh transmission has 3rd and 4th speed stages of the main change gears synchronized.
Therefore,between these stages,gear shifting while traveling is possible (synchromesh version)
Note:
1st and 2nd speed stages of main change must be surely stopped traveling.
2. PTO DRIVE SYSTEM
1) The PTO drive system is composed of the independent PTO clutch and the PTO change gears.
2) The PTO change gears are housed behind the ring gear,which produce 1 PTO speed.
