A.
Integrated auxiliary gearbox
This is an auxiliary gearbox located in the main
gearbox housing. Using an additional set of
gears, the auxiliary shaft of the main gearbox
can be driven by two different ratios. In this way,
each gear in the main box can be engaged in a
low or high ratio, or split into two (also known as
“splitting”). Hence, the number of gears of the
main gearbox is doubled.
B.
Main gearbox
The main gearbox consists of four synchronised
forward gears, and one non-synchronised
reverse gear.
C.
Planetary auxiliary gear
This is a gearbox mounted onto the rear of the
main gearbox, consisting of one planetary gear
wheel set.
Using this set of gears, all gears of the main
gearbox can be used once with the auxiliary
gearbox in a low ratio, and once with the
auxiliary gearbox in a 1:1 ratio.
Hence, the number of gears of the main gearbox
is doubled.
In popular terms, the number of gears in the
gearbox is “stacked”. This is why the term
“stacking box” or range box arose.

By means of the splitter gearbox, the four gears
in the main gearbox are multiplied by two, while
the use of the auxiliary gearbox multiplies this
figure by two again, which results in 4x2x2 = 16
forward gears.
