SHAFT

4.8. A. DRIVE SHAFT PARTS:

SEALS:

Driveshaft assemblies use inboard and outboard

joint seals. The inboard and outboard seals are

made of thermoplastic material. The thermoplastic

material performs well against normal handling

and operational wear conditions. However, it is

not strong enough to withstand abusive handling

or damage due to objects such as sharp tools or

the sharp edges of any other surrounding

component in the vehicle.

The functions of the seal are as below:

To protect the internal parts of the inboard

and outboard joint by protecting the grease

from surrounding detrimental atmospheric

conditions such as stones, dirt, water, salt,

etc.

Facilitate angular and axial movement as

applicable for inboard and outboard joints.

CLAMPS:

These are made of stainless steel. The clamps

provide a leak proof connection at housing and

axle shaft for the inboard and outboard joints.

OUTER JOINT (OUT BOARD JOINT):

The outer joints use the Constant Velocity (CV)

joint design, which is the standard outboard joint

for front wheel drive cars. It is a fixed centre ball

type joint.

The outer housing is made using special steels by

cold forming process followed by heat treatment.

The cold-formed surfaces give superior wear

resistance and increased joint life. The main

function of the outboard joint is to allow the

vehicle’s wheels to turn during steering operation

or have a steer capability.

INNER JOINT (IN BOARD JOINT):

This is a Constant Velocity universal joint radically

self-supported and permitting axial movement

consisting of a housing directly connected to the

axle shaft through three equally spaced

transmission mounted balls. These are made of

special steels through complex forming process

followed by heat treatment. The main function of

the inboard joint is to allow the half shaft assembly

to compensate for suspension movement in the

vehicle by allowing the shaft to move axially or

stroke in the inboard housing.

AXLE SHAFT:

The axle shaft simply connects the inboard joint

and the outboard joint. It is made out of special

steel heat treated to give optimum strength and

fatigue performance. The function of the axle shaft

is to transmit torque and rotation to the wheel from

the transmission.

Note:

The rubber damper is fitted on RH driveshaft only.
