Automatic Hand Brake System” is an industrial project which meets the above requirements efficiently. A motor with the braking system is used for the operation of the automatic brake mechanism. By taking an inventory of all the essential mechanical components and doing a basic mechanical component evaluation, you can get a good idea how
much the brake work efficiently.
TYPES OF BRAKES:
(a) Frictional brakes->
are most common and can be divided broadly into “shoe” or “pad” brakes, using an explicit wear surface, and hydrodynamic brakes, such as parachutes, which use friction in a working fluid and do not explicitly wear. Typically the term “friction brake” is used to mean pad/shoe brakes and excludes hydrodynamic brakes, even though hydrodynamic brakes use friction
(b) Pumping brakes->
are often used where a pump is already part of the machinery. For example, an internal-combustion piston motor can have the fuel supply stopped, and then internal pumping losses of the engine create some braking. Some engines use a valve override called a Jake brake to greatly increase pumping losses. Pumping brakes can dump energy as heat or can be regenerative brakes that recharge a pressure reservoir called a hydraulic accumulator.

(c) Electromagnetic brakes->
are likewise often used where an electric motor is already part of the machinery. For example, many hybrid gasoline/electric vehicles use the electric motor as a generator to charge electric batteries and also as a regenerative brake. Some diesel/electric railroad locomotives use the electric motors to generate electricity which is then sent to a resistor bank and dumped as heat. Some vehicles, such as some transit buses, do not already have an electric motor but use a secondary “retarder” brake that is effectively a generator with an internal short-circuit. Related types of such a break are eddy current brakes, and electro-mechanical brakes (which actually are magnetically driven friction brakes, but nowadays are often just called “electromagnetic brakes” as well).
Why was it needed?
- In the modern lifestyle braking of cars is itself a tedious and important process.
- Places like Metro station, Supermarket, Local market and sometimes on streets do not have enough space for a free ride so we need a brake at that time.
- So we require a system which can make braking easy, less time taking and also using less area to stop the car.
- The system should also be less expensive as people will not like to spend much extra money for such accessories.
