The document provides an overview of power steering systems. It discusses the history of power steering from its invention in the early 1900s to its use in automobiles and agricultural vehicles. The key components of power steering systems are described including the reservoir, steering gearbox, rotary valve, and pump. The main types of power steering systems - hydraulic, electro-hydraulic, and electric - are outlined along with diagrams of how each system works. Advantages like reduced driver fatigue and continuous steering are balanced with potential disadvantages such as leakage and vibration.

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. 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.

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.

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.
