COMPANY PROFILE
TML Drivelines Limited is predominantly in the business of manufacturing Axles &
Transmission for the commercial vehicles. In the year 2000, the erstwhile Axle & Transmission
manufacturing divisions of Tata Motors were spun off as 100% subsidiaries HVAL & HVTL
respectively. The key intent of incorporation was to give specialist focus on development and
supplies of Axles and Transmissions for Tata Motors, while Tata Motors concentrated on
vehicle Design, integration & Marketing. In the year 2011-2012, the Boards of the two
Companies decided to amalgamate HVTL into HVAL to harness synergies and graduate the
two entities as a Total Drivelines Solutions Provider. HVTL was accordingly amalgamated
with HVTL & HVAL was then renamed as TKL Drivelines Limited in FY2011-12. The
company operates as a Business to Business (B2B) entity with TML. It continues to cater to
more than 90% of the Axle and Gear-box requirements in the M&HCV Range to TML by
supplying to all three locations of TML- Jamshedpur, Lucknow & Pune.
Axles and Transmissions as aggregates are very critical for Tata Motors, and TML Drivelines
provides these aggregate to Tata Motors with a distinct advantage in terms of quality, cost and
new products which dovetails with their core competence. The company traditionally focused
on M&HCV aggregates for the Jamshedpur & Lucknow plants of Tata Motors. Of late, TML
Drivelines has also ventured into LCV segment & supply of its aggregates to Pune plant of
Tata Motors. TML Drivelines has set up its own Design & Development Centre. ERC which
has also received DSIR Recognition.
TML Drivelines is organised into three verticals viz. Axles, Transmissions and Forge. Axles
vertical is further categorized into Front Axle, Rear Axle, Drive head and Defence Aggregates.
Transmission vertical has Gear soft, Heat Treatment, Gear-Hand and Assembly. Forge has two
verticals comprising axle-RA Shaft and FA Beam-Crank Shaft. TML Drivelines possesses all
the modern technologies and facilities required for axle and gear box manufacturing.
TML Drivelines is organized into three verticals viz. Axles, Transmissions and Forge. Axles
vertical is further categorized into Front Axle, Rear Axle, Drive Head and Defence Aggregates.

CONCLUSION:
This report is an illustration about the study that I have done during this 4 weeks
of summer internship. I have got a detailed knowledge about the front axle and
the rear axle unit of ERC in TML Drivelines. I have understood the detailed role
of ERC in TML Drivelines. Apart from axle department I have learned to use
the basics of PLM software from Siemens.
During this 4 weeks of tenure I had a great learning experience in TML
Drivelines, Tata Motors in Jamshedpur. During this period of time I have gone
through the Heat Treatment plant of pinion and crown wheel and learned about
the process. These learning experiences will certainly help me in the future.
