AXLES-REAR
to match the clutch teeth on the spider through which
driving torque is transmitted.
Radially inward from the
driven clutch teeth on models using internal spring are
cams which mesh with the cams of the center cam
member.
These cams have been eliminated on the
models using the external spring.
The internal diameter
of each driven clutch member has splines which engage
the external splines of the splined side members.
Spring Retainers and Springs
Models with Internal Springs
Spring retainers are inserted into the outer ends of
driven clutch member.
The bowl side of these retainers
is mounted first through the outer side of the driven
clutch members.
The flanged portion of the spring
retainers pass through the internal splines to rest on the
mating flanges of the driven clutch members.
The
springs are mounted in spring retainers after assembly
and thrust against their inner cupped ends.
Models with External Springs
Spring retainers fit over the side gear, passing through
external splines to seat against the shoulder on the side
gear.
Springs fit between the driven clutch and outer
flanged surface of the spring retainer.
Splined Members
These two splined side members are splined internally
to receive the truck axle shafts.
The inner hubs of the
splined side members are inserted in the outer ends of
the springs.
The external splines of the splined side
members engage the internal splines of driven clutch
members on each side of the completed assembly.
OPERATION
Straight Forward Driving
When a vehicle is being driven in a straight forward
direction, the clutch teeth on both sides of the spider
assembly are fully engaged with the clutch teeth on each
driven clutch member.
Likewise, the fixed cams of the
driven clutch members are fully meshed with the cam
surfaces of the floating center cam ring mounted on the
inside diameter of the spider, as described previously.
Engagement of the driving and driven clutch teeth is
assured by the pressure of the two springs which force
the driven clutch members inwardly against the spider
and also by the positive locking action developed by
