Clutch Mechanism
A dry double-plate type, constantly en-
gaged clutch is installed on the engine
flywheel (1).
A dry double-plate type, constantly en-
gaged clutch is installed on the engine
flywheel (1).
The flywheel (1), the pressure plate (3)
and the intermediate plate (2) with three
prongs on its surface, which enter into
special slots on the flywheel (1), consti-
tute the driving section of the clutch. The
driven section of the clutch consists of
two driven plates (24) fitted with vibration
dampers (9) installed on the power-
transmission shaft (7). A necessary
pressing force of friction surfaces of the
clutch driving and driven sections is de-
veloped by nine external and internal
springs (22). A resilient element is in-
stalled between the floating bushing (8),
coupled with the driving shaft (4), and the
clutch bearing plate (12).
The intermediate plate (2) is fitted with
leverage mechanisms (11) which operate
to place the plate (2) equidistant from the
friction surfaces of the flywheel (1) and
the pressure plate (3), when the clutch is
disengaged. The forks (13) fastened on
the bearing disk by means of the adjust-
ing nuts (15) locked by the washers (14)
serve as supporting points for the clutch
release levers.
The engagement and disengagement of
the clutch are achieved with the help of
the clutch release shifter (17) assembled
with the throw-out bearing (16) which can
slide along the support (18). The shifter
fork (19) together with spindle (20) is
connected with the clutch pedal through
a hydrostatic actuator.
The throw-out bearing (16) is lubricated
through a grease nipple screwed in into
the shifter shank.
The grease nipple is on the left-hand
side of the clutch housing. It is necessary
to unscrew the plug (A) to gain access
thereto.
