WHAT IS STEERING??

HOW THIS STEERING SYSTEM WORKS?

WHAT TYPE OF MECHANISM USED IN STEERING AND IT'S COMPONENTS

Great steer handling makes you feel safe and in control
The softer touch of the wheel should direct the steering system effectively. As well as well-designed suspension, it builds a good quality steering system and steering parts to achieve better handling. If you’d like to know more about anatomy of a steering system and how it helps in handling, road holding and driveability,
There is an simple overview.

Role of steering system in a car:-

When you rotate the steering wheel, the car responds. But how does this steering system in cars give you a smooth feel do you know?
A group of parts called the steering system allows the movement of the steering wheel and the steering shaft to move the wheels left and right – although car wheels don’t turn at that angle

TYPE OF STEERING SYSTEM:-

® MECHANICAL STEERING SYSTEM
Low maintenance costs
More physical effort
Less efficient

      Recirculating ball type

      Rack & pinion type

® POWER STEERING SYSTEM
More efficient 
Less physical effort
High maintenance 

      Electronic type
      Hydraulic type

 

In this article we discuss about rack & pinion type steering system

Rack and pinion steering system:-

In most of cars, small trucks and in SUVs today, there is a rack and pinion steering system. This converts the rotational motion of the steering wheel into the rectilinear motion and that's turns the wheels and guides your path.
The system have a circular gear (the steering pinion) which  teeth mashed on a bar (the rack).
and transforms  rotations of the steering wheel into, accurate turns of the wheels, giving a direct feel to the steering

PARTS OF STEERING SYSTEM

Steering wheel

∆ Enable the driver to control the direction of vehicle.
∆ Circular in shape and mounted on the steering column.
∆ Horn pad and airbags ari situated on the steering wheel.

Steering column

∆ Steering column is a mechnical link between steering wheel and steering gear box.
∆ Steering column is the type of telescopic or tilt type.

Steering column and universal joint

Universal joint

∆ Perpose of universal joint is to transmit rotary motion to another which is attached in any angle
∆ It joint the steering column and rack& pinion

Steering gear box

∆ Steering gear box is a device which converts the rotary motion of steering wheel into straight line motion of the linkage.
Type of steering gear box is:
• Rack and pinion type
• Recirculating ball type

Steering gear box

Rack and pinion

∆ This converts the rotational motion of the steering wheel into the rectilinear motion and that's turns the wheels and guides your path.
∆ The system have a circular gear (the steering pinion) which  teeth mashed on a bar (the rack).
and transforms  rotations of the steering wheel into, accurate turns of the wheels,

Rack & pinion system

Recirculating ball

Steering pump

∆ The hydraulic power steering system uses a pump to provide assistance.
∆ Vane type pump is used.
Driven by crankshaft by belt and pully.
∆ Amount of pressure delivered by pump depends on the engine speed.

Reservoir

∆ Fluid reservoir stores the steering fluid witch is needed for the power steering operation.

Tie rods

∆ Tie the steering knuckle to the centre track rod/steering rack and adjuster adjusts the toe in/out

Damper coupling

∆ To prevent the shocks being transmitted from the wheel rod to Steering wheel.
∆ It is fitted between steering wheel and steering gear box.
