4. 4 HISTORY First installed in 1876. On April 1900, Robert Twyfrod from USA got the patent for the first four wheel drive system. In 1926 demonstrated the first PSS . On agricultural tractors in the early 1950’s. Suitable for small to medium tractors where power steering can be an option to manual steering.

5. 5 Components in power steering Reservoir Steering gear box Rotary valve Pump

6. 6 RESERVOIR

7. 7 Steering gears are enclosed in a casing known as steering gear box Steering gear box

8. 8 Rotary valve A rotary valve for a power steering system includes a valve sleeve in which a rotor is rotatably carried for controlling fluid flow from a supply pump to a cylinder of the power steering system.

9. Pump Driven by vehicle’s engine. Amount of flow depends on engine’s speed. 9

10. 10 Types of power steering Hydraulic Electro-hydraulic [E.H.P.S] Electric

11. 11 component of Hydraulic system:-

12. 12 Working of Hydraulic system

13. 13 Electro- Hydraulic system Hybrid System Use the same hydraulic assist technology as standard systems. Electric motor instead of being belt-driven by the engine.

14. 14 Electric system It Mainly Contains :- EPS ECU Motor. Sensor.

15. 15 Working of Electric system

16. 16 H.P. S V/S E.P.S Complication weights Maintainance Response Power consumption

17. 17 APPLICATIONS Now a days, these are used in almost all the heavy vehicles.

18. 18 ADVANTAGES Reducing the driver’s fatigue. Low input torque and continuous steering function. Oil output directly proportional to the steering speed.

19. 19 DISADVANTAGES Leakage Less Durability Vibration

20. 20 CONCLUSION By studying all these, we can conclude that the power steering is necessary for the modern cars. It provides good handling to the driver, gives better comfort, and make him less fatigue.
