A. Integrated front-mounted range box
This is a front-mounted range box located in the
main box housing. Using an additional set of
gears, the auxiliary shaft of the main box 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, i.e. split into two. The number of
gears in the main box is thereby doubled.
B. Main box
The main box consists of four synchromesh
forward gears, and one non-synchromesh
reverse gear.
C. Planetary rear-mounted range box
This is a range box mounted against the rear of
the main box, consisting of a planetary gear
wheel set.
Using this set of gears, all gears of the main box
can be used once with the rear-mounted range
box in a low ratio and once with the
rear-mounted range box in a 1:1 ratio.
The number of gears in the main box is thereby
doubled.
In popular terms, the number of gears in the
main box is “stacked”. This is why the term
“stacking box” or range box was created.
16S-151/181/221
By means of the splitter range, the four gears in
the main box are multiplied by two, while using
the rear-mounted range box multiplies this figure
by two again. This results in 4x2x2 = 16 forward
gears.
