Steering is the term applied to the collection of components, linkages, etc.

Power steering is a system which helps to steer the wheels with some source of power other than the driver’s manual force .

INTRODUTION

5

HISTORY in February 1902. August 30,1932. 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.

Once the size of the tractor becomes too big for manual steering, hydro-mechanical steering is usually not cost effective.

Rotatory 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.

Electro- Hydraulic system

• Hybrid System• Use the same hydraulic

assist technology as standard systems.

• Electric motor instead of being belt-driven by the engine.

APPLICATIONS Now a days, these are used in

almost all the heavy vehicles.

19

ADVANTAGES Reducing the driver’s fatigue. Low input torque and continuous

steering function. Oil output directly proportional to the

steering speed.

DISADVANTAGES

Leakage

Less Durability

Vibration

21

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.
