1. AXLE: An axle is a central shaft for a rotating wheel or
gear.
(a) Dead Axle: A dead axle, also called lazy axle, is not part
of the drive train but is instead free-rotating. Many trucks
and trailers use dead axles for strictly load-bearing
purposes.
(b) Drive axle: The drive axle is a split axle with a differential
and universal joints between the two half axles
(c) Lift axle: These axles can carry more weight than a semi-
floating or non-floating axle assembly because the hubs
have two bearings riding on a fixed spindle
2. BRAKE CHAMBER: Air brake chambers are the primary
part of the air brake system
3. DRAGLINK: Provides the connection between the driver
and the steering system
BRIEF DESCRIPTION OF PARTS:
The main testing’s done in logistic center are:
1. Differential leakage testing
2. Hub play/longitudinal play testing
3. Oil check in rear axle
TESTING PERFORMED IN LOGISTIC CENTER
• There are a couple places that it can leak. One is the
differential cover( the big melon looking thing right in
the middle of the axle) located on both axle's front
and rear. If it is leaking the bottom of it will look wet.
The second is the axle shaft seals located at the end
of the axle. This would require removal of the wheel
and hub assembly to diagnose.
DIFFERENTIAL LEAKAGE TESTING
• Hub play testing is done manually. It involves the use of a
instrument known as a dial test indicator. The trailer wheel
hub assembly connects the trailer tires to the trailer axle
and facilitates their spin. If those wheel hubs corrode or
aren't installed properly, it will throw the trailer tires out of
alignment and could lead to serious damage of your
vehicle
• For safe working of the axle the hub play should be around
40 to 120 micron. If the reading obtained is in between
this range the axle is considered to be safe for working
otherwise the axle is hold.
HUB PLAY TESTING
TRAILOR HUB
I. Some of the assembly part is covered in logistic
center itself. Trained professional are required for
this type of assembly as it is done manually.
II. Assembly part is completed by conjoining draglink
and brake chamber to the front axle
III. Rest all the assembly is done in assembly lines

In Tata motors the manufacturing of crown wheel and
pinion takes place by various gear cutting process
• A crown wheel is a type of circular gear wheel with teeth that extend perpendicular to the base. These gears are often used along with a pinion to rotate a mechanical device
MANUFACTURING DIVISION
• Hobbing: is the process of generating gear teeth by means of a rotating cutter called a hob. It is a process in which both the cutting fool & work piece rotate in a constant relationship while the hob is being fed into work.
• GLEASON METHOD: The rotating cutters revolve about their axes to provide the cutting action. At the same time, they participate in the relative rolling motion between the cutters and blank to obtain the required tooth profile
GEAR CUTTING PROCESS
• Some of the things a dynamometer will tell you is
torque, hp on the ground, fuel distribution, oil pressure,
head pressure, etc., It will tell you what is going on with
the engine at that time and should tell you the general
condition of the engine. An oil analysis will reveal any
excessive wear going on in the engine. It is a good way
to check out a possible engine component failure before
the failure. It enables you to replace components before
they fail and cause potential damage to the engine. The
oil sample is usually done at the same time you do an
oil change, but you can have one done at any time.
