DRIVELINES - Rear Drivelines

DESCRIPTION
Numbers in parentheses refer to Fig. 1.
The function of the driveline is to transmit rotating
power from one point to another in a smooth and
continuous action while allowing a degree of
movement or misalignment of the components it
connects.
The drivelines must operate through constantly
changing relative angles between the components
they are mounted to and must also be capable of
changing length while transmitting torque.
A typical driveline consists of universal joints which
allow some misalignment and permit the driveline to
pivot in any direction, and, a light rigid hollow slip yoke
and splined shaft assembly forming a slip joint.
The slip joint accommodates length variations
generated during operation, preventing tension or
compression loads from causing serious damage to
the components.
Note: Extra care should be taken when handling the
drivelines since chips, dents, burrs or deformity on any
rotating mass creates vibration and excessive wear
during any operation.
There are two driveline assemblies connecting the
centre and rear axles to the drive supplied from the
transmission, through the pivot drive arrangement, as
follows:
Driveline assembly (1) is connected between the
articulation and oscillation pivot and the centre axle.
Driveline assembly (4) is connected between the centre
axle and the rear axle.
REMOVAL
Numbers in parentheses refer to Fig. 1, unless
otherwise specified.
Note: Extra care should be taken when handling
drivelines since carelessness can result in premature
failure of the components. Chips, dents, burrs, or any
other deformity of universal joints will prevent accurate
mating. This will cause misalignment which is
accompanied by vibration and excessive wear.
WARNINGS
To prevent personal injury and property
damage, be sure wheel blocks, blocking
materials and lifting equipment are properly
secured and of adequate capacity to do the job
safely.
