Differential lockup Clutch
A multi-disk hydraulically controlled dif-
ferential lockup clutch (2) is located in
casing (1), which, through the casing of
the right-hand brake (11) and the bearing
shell (12), is fastened by bolts (16) to the
rear axle housing.
1 – casing; 2 – lock clutch; 3 – adapter; 4 – diaphragm cover; 5 – pressure plate; 6 – diaphragm; 7 – re-
lease plate; 8 – intermediate disk; 9 – clutch housing; 10, 15 – brake disks; 11 – right-hand brake case;
12 – bearing shell; 13 – lockup shaft; 14 – differential spider; 16 – bolt.
The clutch is composed of a shaft (13)
which is connected by means of splines
with the differential spider (14), casing
(9), pressure plate (5), release plate (7),
diaphragm (6), cover (4), adapter (3) and
disks (10, 15) splined on the right-hand
driving pinion of the hub drive.
When oil is fed under pressure into the
working chamber “A” from the ADL hy-
draulic system, the diaphragm (6) moves
together with the pressure plate (5) and
press the disks (10, 15) against surfaces
of the casing (9), intermediate disk (8)
and that of the release plate (7), thus,
locking the differential (i.e., the differen-
tial spider gets interlocked with the right-
hand axle-shaft gear). When the cham-
ber “
А” communicates with the drain, the
differential gets unlocked.
The normal position of the lock clutch is
disengaged.
