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 three driveline assemblies installed
between various components in the tractor frame as
follows:
Driveline assembly (1) is connected between the
engine drive and transmission input drive.
Driveline assembly (2) is connected between the front
axle drive flange and transmission final drive.
Driveline assembly (3) connects the rear final drive of
the transmission to the articulation and oscillation
pivot.
