BRAKING SYSTEM

BRAKING SYSTEM

The vehicle brake used to slow down a vehicle by converting its Kinetic Energy into Heat energy.

It basically inhibits motion, slowing down or stopping a moving object or preventing its motion.

REQUIREMENTS OF A BRAKING SYSTEM

  Stops the vehicle within smallest possible distance.

  Acts instantaneously in case of an emergency.

  Strong enough to sustain sudden braking force.

  Neither slips nor should cause any skid the vehicle.

  Operates with the least effort.

TYPES OF BRAKES

  MECHANICAL BRAKES

  HYDRAULIC RAKES

  PNEUMATIC BRAKES

  ELECTRIC  BRAKES

HYDRAULIC BRAKES

Hydraulic brakes are actuated by the hydraulic pressure (pressure of a fluid). It is commonly used in the automobiles.

WORKING PRINCIPLE : Hydraulic brakes work on the principle of Pascal’s law.

PASCALS LAW :

“Pressure at a point in a fluid is equal in all directions in space”.

DISC BRAKE

The disc brake is a wheel brake which slows rotation of the wheel by the friction caused by pushing brake pads against a brake disc with a set of callipers.

 DRUM BRAKE

A drum brake is a brake that uses friction caused by a set of shoes or pads that press against a rotating drum-shaped part called a brake drum. The term drum brake usually means a brake in which shoes press on the inner surface of the drum.

ADVANTAGES OF DISC BRAKE OVER DRUM BRAKE

  Lighter in weight .

  Better performance in wet conditions.

  Less prone to brake fade due to better heat   dissipation. Brake ducts may be installed to improve heat dissipation further.

   It also has the advantage of being self adjusting.

   It is more efficient.

ANTILOCK BRAKING SYSTEM (ABS)

ABS addresses two conditions related to brake application, wheel lockup and vehicle directional control. Without ABS when brakes are applied with enough force to lock the wheels, the vehicle may slide uncontrollably. ABS Systems use speed sensors at the wheels. The speed sensors are monitored by ECU.
