2. INDRODUCTION
Steering: The act of Guiding or Showing the way
Steering Mechanism: A mechanism by which something is
steered.(Especially motor vehicle)
FUNCTIONS OF STEERING SYSTEMS
• It helps in swinging the wheels to the left or right.
• It converts the rotary movement of the steering wheel into
an angular turn of the front wheels.
• It multiplies the effort of the driver by leverage in order to make it
fairly easy to turn the wheels.

4. BASIC STEERING SYSTEM
PINION GEAR :- Rotated by the steering wheel and steering
shaft, it’s teeth mesh with the teeth on the rack.
RACK :- Long steel bar with the teeth along one section, slides
sideways as the pinion gear turns.
TIE RODS :- Connects the rack with the steering Knuckle.

5. POWER STEERING SYSTEM
Power Steering is a system for steering which uses power from the
engine so that it is easier for the driver to steer the vehicle.
HYDRAULIC POWER STEERING
Most power steering systems work by using a hydraulic system to
steer the vehicle's wheels. The hydraulic pressure typically comes
from a generator or rotary vane pump driven by the vehicle's
engine.

8. ADVANTAGES OF HPS
• Absorbs road shocks
• Minimum efforts
• Greater safety
• Controllability under critical situations
• Oil output directly proportional to the steering speed
