The Transmission for commercial vehicles 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 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 for commercial vehicles 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.
