INTRODUTION
Brake is a device used to stop a moving vehicle by
applying pressure on wheels
Braking system plays an important role in stopping an
automobile
Any moving automobile has kinetic energy in order to stop
them a contact material is applied to the tyres due to which
friction creates and eventually train stops
BRAKING SYSTEM IN TRAINS
Generally many countries use pneumatic
brakes in their trains
Braking system which uses air as fluid is known as
pneumatic braking system
Pneumatic brake is a type of friction brake for
vehicles in which compressed air pressing on piston
is used to apply pressure on break pad to stop the
train
BLOCK DIAGRAM OF PNEUMATIC BRAKING SYSTEM
MAJOR PARTS OF BRAKING SYSTEM
 Air compressor: It pumps air in to the reservoirs
 Air storage: They are used to allow compressed air. They hold
enough air to allow brakes to use even compressor fails
 Brake valve: brakes are applied bypushing down the brake
valve
 Brake cylinder: this is provided foractuating the brake
rigging for application of brakes
 Triple valve: while using brakes the pipe pressure has to be
reduced with respect to brake valve .during these operations
triple valve is used
STAGES IN BRAKING
Charging stage
Application
Release stage
CHARGING STAGE
During this stage brake pipe is charged to pressure
There is no application of brake in this stage
APPLICATION STAGE
In order to apply brakes pressure inbrake pipes has to be dropped
Reduction in brake pipe pressure positions distributor valve in such a way
that auxiliary reservoir gets connected to brake cylinder
RELEASE STAGE
During this stage brake pipe is again charged to normal position
Auxiliary cylinder gets isolated from distributor valve
Braking cylinder is exposed to atmospheric pressure and brakes
are released
CONCLUSION
These brakes became popular because of
high stopping power compared to hydraulic
brakes
They are fail safe
So they are used in heavy vehicles like trains
,trucks etc.
