4. INTRODUCTION
• Steering is the term applied to the
collection ofcomponents, linkages, etc.
which allow for a car orother vehicle to
follow a course determined by its driver.
5. HISTORY
• Hydro-mechanical power steering was
thefirst type to be used on agricultural
tractors inthe early 1950’s.
• Suitable for small to medium tractors
wherepower steering can be an option to
manualsteering.
• Once the size of the tractor becomes too
big for manual steering, hydro-
mechanicalsteering is usually not cost
effective.
6. GENERAL CIRCUIT
OIL RESERVoir
Must be large enough to hold more than all of the oil for the system . Should
be capable of dissipating heat in oil.
HYDRAULIC LINES
Flexible hoses due to the steering components movements.

9. Future of Power Steering
As the majority of today’s hydraulic power steering
systems are designed to have the steering pump
running constantly, pumping fluid around the
system, it wastes valuable horse power, which
translates into wasted efficiency and therefore fuel .
One concept is the "steer-by-wire" or "drive-by-
wire“ system. These system would completely
eliminate the mechanical connection between the
steering wheel and the steering, replacing it with a
purely electronic control system.
10. ADVANTAGES
Preventing the wheels from transferring
the load to the steering column
Reducing the driver’s fatigue
Low input torque and continuous
steering function
Oil output directly proportional to the
steering speed
12. conclusion
By studying all these we can conclude that the
power steering is nesessary for the modern
cars.
Now a days we can see almost all cars having a
power steering.
It provides good handling to the driver, gives
better comfort, and make him less fatigue.
