hydraulic brakes and anti lock braking system(abs)

Welcome !!!

;) :) ;D

Friends !!!

What will u learn ???

(1)Pascal's law of transmission of pressure ;)

(2) How a basic hydraulic system works ;) ;D

(3) How a Hydraulic brake works in a car/bike

(4) How ABS works and why it is considered

as most advanced braking system ;) ; D

(5) And a lots of cleared concepts

Principle of transmission of

fluid pressure: Pascal's law or the

principle of transmission

of fluid-pressure is a

principle in fluid

mechanics that states,

that any force applied to a

confined, incompressible

fluid is transmitted in all

directions throughout the

fluid regardless of the

shape of the container.

HYDRAULIC AND

HYDRAULICSThe word "hydraulic" is derived from two Greek words: "hydro" meaning liquid or water and "aulos" meaning pipe or tubing. "Hydraulic," therefore, is an adjective implying that the word it modifies is in some major way concerned with liquids. Examples can be found in the everyday usage of "hydraulic" in connection with familiar items such as automobile jacks and brakes. As a further example, the phrase "hydraulic freight elevator" refers to an elevator ascending and descending on a column of liquid instead of using cables and a drum.

On the other hand, the word

"hydraulics" is the generic name of a

subject. According to the dictionary

"hydraulics" is defined as a branch of

science that deals with practical

applications (such as the

transmission of energy or the effects

of flow) of a liquid in motion.

ABSWhat is ABS ???

;) ;D

Anti-lock braking system (ABS) is an

automobile safety system that allows

the wheels of a motor vehicle to maintain

tractive contact with the road surface

according to driver inputs while braking,

preventing the wheels from locking up

(ceasing rotation) and

avoiding uncontrolled skidding.

Components of ABS

1.Speed sensors

2.Valves

3.Pump

4.Controller

Speed sensors

A speed sensor is used to determine the acceleration or deceleration of the wheel.These sensors use a magnet and a coil of wire to generate a signal. The rotation of the wheel or differential induces a magnetic field around the sensor. The fluctuations of this magnetic field generate a voltage into the sensor.

Since the voltage inducted on the sensor is a result of the rotating wheel, this sensor can become inaccurate at slow speeds. The slower rotation of the wheel can cause inaccurate fluctuations in the magnetic field and thus cause inaccurate readings to the controller.

Valves

There is a valve in the brake line of each brake controlled by the ABS. On some systems, the valve has three positions:

In position one, the valve is open; pressure from the master cylinder is passed right through to the brake.

In position two, the valve blocks the line, isolating that brake from the master cylinder. This prevents the pressure from rising further should the driver push the brake pedal harder.

In position three, the valve releases some of the pressure from the brake.

The Pump

The pump in the ABS is used

to restore the pressure to the

hydraulic brakes after the

valves have released it.

A signal from the controller will

release the valve at the

detection of wheel slip.

After a valve release the pressure

supplied from the user, the pump is

used to restore a desired amount of

pressure to the braking system.

The controller will modulate the

pumps status in order to provide the

desired amount of pressure and

reduce slipping.

The Controller

The controller is an ECU type unit in

the car which receives information

from each individual wheel speed

sensor, in turn if a wheel loses traction

the signal is sent to the controller, the

controller will then limit the brake force

(EBD) and activate the ABS modulator

which actuates the braking valves on

and off.
