TYPE OF BRAKING SYSTEM , Most brakes use friction on the 2 sides of the wheel,
the collective continue the wheel converts the K.E. of the moving object into heat.
regenerative braking turns much of the energy to electrical energy, which may be stored for later use.
Eddy current brakes use magnetic fields to convert kinetic energy into electrical current in the brake disc, blade, or rail,
further electrical current converted into heat.
The following are the foremost common sorts of braking systems in modern cars.
It’s always good to understand which of them suits your car for straightforward troubleshooting and servicing.
Hydraulic braking system:
This system runs on brake fluid, cylinders, and friction.
glycol ethers or diethylene glycol forces the restraint to prevent the wheels from moving.
• The force generated in the hydraulic braking system is higher than the mechanical braking system.
• The hydraulic braking system considered together of the important braking systems for contemporary vehicles.
• The chance of brake failure is very less in the case of the hydraulic braking system. The direct connection between the actuator and therefore the brake disc or drum makes very little chance of breakdown.
Electromagnetic braking system:
Electromagnetic braking systems are found in many modern and hybrid vehicles.
The electromagnetic braking system uses the principle of electromagnetism to achieve frictionless braking.
This serves to increase the life span and reliability of brakes.
traditional braking systems are susceptible to slip
while this is often back with the fast magnetic brakes.
So without friction or need for lubrication,
this technology is prefer in hybrid.
it is quite modest in size compare to the traditional braking systems.
It is mostly use in the trams and trains.
To make electromagnetic brakes work,
a magnetic flux when passed during a direction perpendicular to the rotating direction of the wheel,
we see a rapid current flowing during a direction opposite to the rotation of the wheel.
This creates an opposing force to the wheel rotation and it slows down the wheel.
Advantages of Electromagnetic braking system:
• Electromagnetic braking is fast and cheap.
• In electromagnetic braking,
there is no maintenance cost like replacing brake shoes periodically.
• By using electromagnetic braking, the capacity of the system( like higher speeds, heavy loads) can be improved.
• A part of the energy is delivered to the supply consequently the running cost is reduced.
• a negligible amount of heat is generated,whereas in mechanical braking enormous heat is produced at brake shoes
which leads to a brake failure.
Servo braking system:
Also known as vacuum or vacuum-assisted braking.
Among this system,
the pressure applied to the pedal by the driver is increase.
They use the vacuum that is produce in petrol engines
by the air intake system in the engine’s intake pipe or via a vacuum pump in diesel engines.
A brake where power assistance is employed to scale back the human effort.
In a car,
engine vacuum is often use to make a large-diaphragm flex and operate the control cylinder.
• Servo braking system boosters used with the hydraulic brake system.
The size of the cylinder and the wheels are practically employ.
Vacuum boosters increase the braking force.
• Pushing the brake pedal releases the vacuum on the side of the booster.
The difference in the air pressure pushes the diaphragm for braking the wheel.
Mechanical braking system:
The mechanical braking system powers the hand brake or emergency brake.
It is the type of braking system,
in which the brake force applied on the brake pedal is carried to the final brake drum
or disc rotor by the various mechanical linkage like cylindrical rods, fulcrums, springs, etc.
In order to stop the vehicle.
Mechanical brakes were utilize in several old automobile vehicles but they’re archaic nowadays thank to their less effectiveness.
Types of Brakes:
The disk brake may be a mechanism for slowing or stopping the rotation of a wheel from its motion.
disk brake is generally made from forged iron,
but in some cases,
it also made from composites like carbon-carbon or ceramic -matrix composites.
This is link to the wheel and/or the axle.
To stop the wheel,
friction material within the sort of restraint is force against each side of the disc.
on the disc wheel will slow or stop.
A drum brakes may be a traditional break during,
which the friction is cause by a group of shoes or pads that press against a rotating drum-shaped part called a drum.
The term drum brake usually means a brake during,
which shoes continue the inner surface of the drum.
Where the drum is pinch between two shoes,
almost like a typical disc brake, sometimes called a pinch drum brake,
although such breaks are relatively rare.
