The wheel reduction gears of plane-
tary spur-gear type are intended for
transmitting and increasing the torque
from the FDA differential at various an-
gles of turning of the front steerable driv-
ing wheels.
The reduction gears are mounted in
the casings (35) and connected with the
axle beam by means of spindles (3)
(see Figure “FDA”) and can turn rela-
tively to the FDA beam on the two bear-
ings (9). The spindles are connected
with the wheel reduction gear casing by
means of the bolts (4). The screw (38)
and locknut (37) serve for adjusting the
angle of turn of the wheel reduction
gears.
The pivots (3) are lubricated through
lubricators (6) mounted on the pivots.
The lubricators are protected against
penetration of dirt by means of rubber
caps (5). To protect the pivot bearings
from dirt, the sleeves (8) with sealing
rubber rings (7) are installed in the
housings of the axle beam. The pivot
bearings (9) are adjusted by means of
the shims (2) located under upper spin-
dles (3).
