anti lock braking system

  1. 1. GURU NANAK INSTITUTE OF ENGINEERING AND MANAGEMENT <ul><li>Mechanical Engineering Department </li></ul>
  2. 2. SEMINAR ON ANTI LOCK BRAKING SYSTEM <ul><li>Guided By: </li></ul><ul><li>Er. Shaymal Chakrabarty </li></ul><ul><li>Presented By: </li></ul><ul><li>Sumit O. Ambekar </li></ul>
  3. 3. Introduction to ABS: <ul><li>Applying brakes too hard, or on a slippery surface, can cause the wheels to lock. When wheels lock, steering control is lost and, in most cases, it produces longer stopping distances. The antilock braking system prevents wheels locking or skidding, no matter how hard brakes are applied, or how slippery the road surface. Steering stays under control and stopping distances are generally reduced . </li></ul>
  4. 4. Working of ABS: <ul><li>When the driver hits the brakes this pressurizes the hydraulic system which causes the brake pads to squeeze against the discs which causes the car to slow down. If the ABS system detects that one wheel is slowing down more rapidly than the rest it automatically reduces the brake pressure on this wheel by opening a pressure release valve in the hydraulic system. ABS also has the ability to build the pressure back up via the hydraulic motor. The system reacts remarkably quickly, and compared wheel speeds many times a second. </li></ul>
  5. 5. Diagram 1: <ul><li>Brake caliper (1), </li></ul><ul><li>wheel speed sensor (2) </li></ul>
  6. 6. Diagram 2 :

  8. 8. History: <ul><li>The ABS was first developed for aircraft use in 1929. </li></ul><ul><li>In 1958,Royal Enfield Motorcycle. </li></ul>
  9. 9. Components: <ul><li>There are four main components to an ABS: </li></ul><ul><li>Speed sensors, </li></ul><ul><li>Valves, </li></ul><ul><li>Pump, </li></ul><ul><li>Controller . </li></ul>
  10. 10. Basic Functions of ABS: <ul><li>Static Friction is Greater than Moving Friction. </li></ul><ul><li>ABS Allows the Driver To Maintain Control During Hard Braking . </li></ul>
  11. 11. Advantages of ABS: <ul><li>Stopping on ice. </li></ul><ul><li>Higher resale value . </li></ul><ul><li>ABS is really helpful in tricky situations like corner braking. </li></ul>
  12. 12. Disadvantages of ABS: <ul><li>It is expensive. </li></ul><ul><li>It hard to install. </li></ul><ul><li>Delicate systems . </li></ul>
