COMPONENT DESCRIPTION

NOTE :

Component description is in-line with serial numbers

given in above fig.

1. Seals or Boots :

Driveshaft assemblies use inboard and outboard joint

boots. The inboard and outboard boots 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 boot are :

(a) To lubricate the internal parts of the inboard and

outboard joints.

(b) To facilitate angular and axial movement as

applicable for inboard and outboard joints.

stones, dirt, water or any foreign materials.

2. Clamps :

These aremade of stainless steel. The clamps provide

a leak proof connection at housing and axle shaft for

the inboard and outboard joints. Clamps once used

should not be reused again.

3. In Board Joint (IBJ) and Out Board Joint (OBJ):

These are Constant Velocity universal joints radically

self supported and permitting axial and angular

movement consisting of a housing directly connected

to the axle shaft through three equally spaced

transmission mounted rollers. These are made of

special steels through complex forming process

followed by heat treatment. The main function of these

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 and

outboard housing.

The only difference between two joints is, outboard

joint has threads to accommodate drive shaft lock

nut and inboard joint has splines and locking circlip.

4. Interconnecting Shaft or Bar 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.
