Introduction To Steering System


In an automobile steering system plays a vital role for changing the direction of motion of a vehicle. This is achieved by converting the rotary motion imparted to the steering wheel by the driver into the angular turn of the front wheels. The steering system consists of following major components:


1. Steering Wheel
2. Steering Column and Shaft
3. Steering Gear Box
4. Steering Linkages ( i.e. steering arm, drag link or tie rod)
5. Steering Knuckles ( or stub axles)

When the driver operates the steering wheel, the steering shaft passing through the steering column also rotates with it as it is fixed to the steering wheel. This motion of  steering shaft is transferred to the steering gearbox. It is then converted into the lateral motion (i.e. Straight line motion) by the gearbox and transferred to the steering linkages. 

The left and right linkages are connected to the steering knuckles on the left and right wheels respectively. The each knuckles is pivoted on the suspension's upper and lower arms and rotates about the axis when force is applied. This causes wheels to move left or right, allowing the direction of the vehicle to be changed.

Axles Used in Automobiles

  Axle Beam(Rigid Axle Suspension System) The axle beam is a type of suspension system in which one set of wheels is connected laterally by a single beam or shaft. The axle beams are commonly used at the rear wheels of a vehicle, but historically they have also been used as front axles in rear wheel drive vehicles. The axle beam are typically suspended either by leaf springs or coil springs. The advantages of the axle beam is that  it is simple and easy to manufacture. The disadvantage is that it does not allow each wheel to move independently in response to bumps, and the mass of the beam is a part of the unsprung weight of the vehicle, which can further reduce the ride quality.  The following type of axles are used in automobiles: 1.  Live Axle : The live axle contains a big housing for enclosing differential which transmits rotary motion to the wheels. These axles are also known as drive axles.These can be further classified into two categories: a)  Banjo Typ...

Suspension Systems of Automobiles

Introduction to Suspension System The suspension system is located between the wheels and body of the vehicle. This system is specially designed for damping the vibration and shocks which may cause damage and affect in comfort of the automobiles. The main purposes of the suspension are as follows: 1.It connects the vehicle body and the wheels, and thus supports the weight of the vehicle. 2.It works together with wheels to absorb vibrations and shocks from the road surface, so as to improve driving comfort and protect the passengers from road socks. 3.It ensures that the wheels are always firmly in contact with the road surface and maintains the inclination of body in order to improve the stability of the vehicle in any possible driving condition including acceleration, braking and cornering. The design and construction of individual suspension components is dependent on the type of suspension system used in the vehicle. The main components of a suspension system are the  springs ...
