- 3. Introduction Steering is the term applied to the collection of components, linkages, etc. Which will allow a vehicle to follow the desired course. An automobile is steered with the help of steering gears and linkages which transfer the motion of the hand operated steering wheel to the pivoted front wheel hubs via steering column. The other parts that are used for steering a vehicle are steering wheel pads, steering shaft, steering box, steering arm and steering stabilizers. These parts are made of durable materials like stainless steel, iron, aluminium, copper, magnesium, etc.
- 4. FUNCTION OF A STREEING SYSTEM To Control The Angular Motion of Wheel And Thus The Direction Of Motion Of The Vehicles. To Provide Directional Stability Of The Vehicle While Going Straight Ahead. To Minimize Tyre Wear And Increase Its Life.

- 6. Components of Steering System STEERING WHEEL : A wheel turned by the driver of a motor vehicle, ship, etc, when he or she wants to change the direction of the vehicle or ship. STEERING COLUMN : A shaft connecting the steering wheel to the steering gear assembly. It is also called steering shaft
- 7. BASIC RACK AND PINION STEERING 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
- 8. STEERING LINKAGE PITMAN ARM : Transfers gearbox motion to the steering linkage. Pitman arm is splinted to the gearbox
- 9. BASIC RACK AND PINION STEERING GEAR HOUSING : It Holds the pinion gear and rack. TIE RODS : Connects the rack with the steering Knuckle
- 10. NEED POWER STEERING Power steering greatly reduces the effort needed to turn the wheels of a car especially with front drive cars, the extra weight and effort can be too much for many drivers. Although not a major concern at highways speeds, low speed turning and manoeuvring are much easier to do. Most power steering systems provide less and less boost the faster you go
- 11. POWER STERING An automobile steering system in which the engine’s power is used to supplement the driver’s effort in turning the steering wheel. The first power steering system on an automobile was apparently installed in 1876 by a man with the surname of FITTS. Next power steering system was put on a Columbia 5-ton truck in 1903 There are two types of power steering 1 Electric power steering 2 Hydraulic power steering
- 12. 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 rotary vane pump driven by the vehicle’s engine. A double acting hydraulic cylinder applies a force to steering gear which in turn steer the road wheel. The steering wheel operates valve to control flow to the cylinder.
- 13. ELECTRIICAL POWER STEERING Electric power steering uses the electric motor to assist the driver of a vehicle. Sensors detect the position and torque of the steering column and computer module applies assistive torque via the motor, which connects to either the steering gear or steering column.
