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.
