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.
