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.

Components in power steering

Reservoir

Steering gear box

Rotary valve

Pump

6

RESERVOIR

7

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

Steering gear box

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.

Pump

Driven by vehicle’s engine.

Amount of flow depends on engine’s speed.

Working of Hydraulic system

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

Electric system

It Mainly Contains :-

EPS ECU

Motor.

Sensor.

15

Working of Electric system

16

H.P. S V/S E.P.S

• Complication

• weights

• Maintainance

• Response

• Power consumption

17

APPLICATIONS

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

18

ADVANTAGES

Reducing the driver’s fatigue.

Low input torque and continuous steering function.

Oil output directly proportional to the steering speed.

19

DISADVANTAGES

Leakage

Less Durability

Vibration

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.
