In a motorcar, the word Powertrain means the main
component that generates power and delivers it to the road surface, water, or
air. The Engines, Transmission, Drive Shafts, Differentials, and Wheels are nothing
but Powertrain components. The most recent research on the Powertrain components is driven by the electrification of it in
multiple components. This leads to larger batteries.
- Engine:
An internal combustion engine is the heart of the Powertrain components. It is a heat
engine where combustion of the fuel occurs with air in a chamber. Here in
this process, chemical energy is converted into mechanical energy.
- Transmission:
Transmission is nothing but a machine which provides controlled
application of the power in a power system. It is often called as gearbox,
gears provide speed and torque. Transmission can also be used in pedal
bicycles where different torque is adapted.
- Drive
Shaft: A drive shaft or cardan shaft transmits the
torque and rotation, generally used to connect other Powertrain components of a drive
train. The drive shafts are subject to torsion and shear stress due to the
torque.
- Differentials:
It is basically a gear train with three shafts. It has an amazing property
that the rotational speed of one shaft is average of the speeds of the
others.
