Hydraulic Cylinder of Steering Control
The tractor is equipped with the FDA
with two hydraulic cylinders (3) and
transverse control arm (4) installed
behind the FDA (see Figure below).
The rods of the hydraulic cylinders are
connected with the pivot rods (2) of the
planetary wheel FDA through the taper
pins (1) and the bodies of the hydraulic
cylinders are connected with the lugs
made of the central reduction gear cas-
ing. The spherical joints (5) requiring the
periodical lubrication through the pro-
vided press lubricators (6) are installed
in the ears of the casings of the wheel
reduction gears and in the heads of the
rods.
FDA with two hydraulic cylinders in the steering linkage and transverse control arm:
1 – taper pin; 2 – reduction gear lever; 3 – hydraulic cylinder; 4 – transverse control arm; 5 – spherical
joint; 6 – press lubricator
The hydraulic cylinder of the steering
wheel (see Figure below) consists of the
body (3) rod (4), piston (1), cover (6)
and sleeve nut (8). The piston is fas-
tened to the rod by means of the nut
(15) which is locked by punching of the
shoulder into the slots of the rod (4). The
spherical ball-and-socket bearings (7)
having the channels on the internal
raceway for lubricating the friction sur-
faces through a lubricator in the pin are
installed in the lugs of the body and rod.
The cup (9) (scraper), rod guides (13)
excluding the friction of the rod and
cover and rod seals (10) are mounted in
the cover (6). The combined seal (14) is
fitted on the piston to exclude the friction
of the piston and sleeve of the body.
