The transmission
is the component used to transfer power from one system to another with the use
of gears or gear trains. The transmission helps in transferring power from the
engine to the required parts( like wheels) in a controlled manner. Thus all the
components lying between engine and wheels act as transmission. It includes
clutch, gearbox, propeller shaft and differential.
The Transmission for the Commercial Vehicles depends upon the load carrying capacity and the
size of the engine. Mainly the transmission systems are divided into three categories
– manual, automatic and semi-automatic transmission system. It works like
gearboxes but the difference arises in their application. The gearboxes can be
used for stationary applications while it can be used agricultural, mining and
industrial work too.
Now-a-days the auto manufacturers concentrate
on automatic transmission instead of manual transmission. The main difference
between the two is the degree of the drivers’ engagement. In manual
transmission, the driver needs to engage and disengage gears while in automatic
transmission everything works automatically. The main aim behind the
introduction of the automatic transmission system is to decrease the involvement
of the driver.
The main use of
the Transmission in Commercial Vehicles is to transfer power
efficiently.
Summary: - It is concluded that transmission system plays a vital role in
the fuel economy of any vehicle and helps in transferring power from engine to
the wheels in efficient and smooth way. So, the auto manufacturers are focusing
to low the engagement of the driver in the working by the use of automatic
transmission.
