Here you can get Types of Braking System. Here we provide Braking System working principle, Classifications, Advantages, and Disadvantages etc. A brake is a mechanical device which inhibits motion.
In an automobile vehicle, a braking system is an arrangement of various linkages and components (brake lines or mechanical linkages, brake drum or brake disc , master cylinder or fulcrums etc) that are arranged in such a fashion that it converts the vehicle’s kinetic energy into the heat energy which in turn stops or de accelerate the vehicle.
The conversion of kinetic energy into heat energy is a function of frictional force generated by the frictional contact between brake shoes and moving drum or disc of a braking system.
Brake is a mechanical device. From a moving system, it absorbs energy and inhibits motion. It is used for reducing the speed of a wheel or axle. It works through friction. The maximum decelerating effect obtained is called peak force, which is the main characteristic of the braking system. The temperature of brakes gets high when they are typically used and this may result in failure of the system.
Classification of Braking System
As we have already discussed the evolution of braking system from vintage carts to modern cars, from vintage carriages to modern trucks has given us various different purpose braking systems which are classified on the basis of various needs and purposes of an automobile vehicle. so let’s just discuss them-
The power source which carries the pedal force applied by the driver on brake pedal to the final brake drum or brake disc in order to de accelerate or stop the vehicle the braking systems are of 6 types-
It is the kind of braking system wherein the brake pressure carried out through the driving force at the brake pedal is transferred to the final brake drum or disc rotor via the various mechanical linkages like cylindrical rods, fulcrums, springs etc. In order to de accelerate or stop the vehicle.
Mechanical braking mostly used in scooters, motor vehicles, and motorcycles where small power is required. It is essential in manufacturing power transmission applications, material handling, etc.
It is the sort of braking system wherein the brake pressure implemented with the aid of using the driver on brake pedal is first transformed into hydraulic pressure by master cylinder (for reference read article on master cylinder) than this hydraulic pressure from master cylinder is transferred to the final brake drum or disc rotor thru brake lines.
It is the types of braking system in which atmospheric air via compressors and valves is used to transmit brake pedal pressure from brake pedal to the very last drum or disc rotor.
It is the traditional kind of braking system in which vacuum within the brake lines causes brake pads to transport which in turn finally stops or de accelerate the vehicle.
In this types of braking system, the magnetic field generated by permanent magnets is used to cause the braking of the vehicle.
It is type of braking used in electric vehicle in which braking is produced the use of the electrical vehicles that is the main source of power in electric vehicles, it is similarly divided into three types-
(i) Plugging Brakes-When the brake pedal is pressed in the electric vehicle equipped with plugging braking, the polarity of the motors changes which in turn reverses the direction of the motor and causes the braking.
(ii) Regenerative Braking- It is the type of electrical braking in which at the time of braking the motor which is the main power source of the vehicle becomes the generator i.e. when brakes are applied, the power supply to the motor cuts off due to which the mechanical energy from the wheels becomes the rotating force for the motor which in turn converts this mechanical energy into the electric energy which is further stored in the battery.
(iii) Dynamic or Rheostat Braking- It is the type of electrical braking in which resistance provided by the rheostat causes the actual braking, in this type a rheostat is attached to the circuit that provides the resistance to the motor which is responsible for de acceleration or stopping of the vehicle.
The components engaged in the drum hydraulic braking system
The brake pedal is connected in this type of manner to the piston of the master cylinder that the wheel motion forces the piston back and forth inside the
master cylinder.
Hydraulic disk components and hydraulic drum brake components are nearly the same as brake pedals or brake levers-precisely similar to the drum brakes
listed above.
All the components of unmarried acting hydraulic brakes and double-acting hydraulic brakes whether it’s a drum type single acting brake or disc type single acting brake are equal as mentioned above, the only difference is kind of master cylinder used which decides the brake force distribution i.e. In motorcycles- single wheel braking or double wheel braking, In cars- wheel braking or all wheel braking. So let’s just see that in detail.
In single acting type of hydraulic brakes, simple single cylinder type of master cylinder is used which provides limited hydraulic pressure which can only be transferred in single direction i.e. In motorcycles- only single wheel, In cars – only single pair(front or rear) of wheels.
In double acting type of hydraulic brakes, double or tandem master cylinder is used which provides better brake pressure that can be transferred in double direction i.e. each wheels in motorcycles and all the wheels in cars.
It is the kind of brakes in which the brakes are carried out while the driver presses the brake pedal mounted inside the cockpit or on the foot area of the car together along with his foot, this pedal pressure carried out through the driving force is in addition expanded and sent to the braking drum or disc both through mechanical linkages or through hydraulic stress which in flip reasons braking.
This kind of brakes are also known as emergency brake as they may be independent of the main service brake, hand brakes includes a hand operated brake lever which is connected to the brake drum or disc rotor thru the steel cable.
Cars have brakes on all 4 wheels that are operated through a hydraulic system. The brakes are both a disc type or drum type. Many cars have 4-wheel disc brakes – despite the fact that a few have discs for the the front wheels and drums for the rear.
Since the lion’s share of stopping a car’s ahead momentum relies on the the the front brakes, the more effective disc brakes are deployed at the the front wheels; much less high-priced drum set-up provides adequate, however greater value powerful, help in halting a automobile’s motion. The car brake system works in some ways:
1). What is the function of braking systems?
A braking system is a mechanical device that allows in accelerating or decelerating the speed of the device. It inhibits movement through absorbing energy from the system.
2). What are the types of brake assist systems?
The types of brake assist systems are hydraulic brake assist system and mechanical braking assist system.
3). What is Pascal’s law?
Blaise Pascal states that when the pressure applied to a fluid(confined in compressible fluid) in a system can transmit equal pressure in all directions throughout the fluid. This law was given by Blaise Pascal in 1647-48.
The formula for pascal’s law is,
P = F/A
Where F= force, A = area, and P= pressure.
