Springs Used in Automobile

 The spring in suspension system are used to absorb the up and down motion of the wheels, when the wheels pass through pot holes and bumps on the road. This protects the passengers from getting shocks or jerks. The springs are placed between the chassis frame and axles. The following types of springs are generally used in automobiles are as follows:

  1. Leaf Springs
  2. Coil Springs
  3. Torsion Bar
>>Leaf  Spring:


The leaf springs used in automobiles are made up of several flat long strips made from spring steel of rectangular cross section. Each of the strips are known as Leaf. The several strips are placed one on the others and are held together by means of a center bolt and clamps. The springs assembly consists of a main leaf which extends to the full length of the spring. The ends of the main leaf are formed with loops known as eyes. The other leaves in the spring are attached to the main leaf by means of center bolt and clamps as in the figure.

>>Coil Spring:


The springs are extensively used in suspension system of automobiles. A standard coil spring is made from a length of special spring steel, usually round in section. It is wound in the shape of a coil as shown in the figure. The ends of the coil spring are kept flat so that they seat properly.

>>Torsion Bar:
The torsion bar is made from spring steel bar which functions by twisting. One end of the torsion bar is fixed to the frame, so that it may  not run. The other end is attached to the lower control arms as shown in figure. When the vehicle goes over a bump or pot hole, the torsion rod gets the twisting effect and the elasticity of the rod is utilized to bring back the wheel to it's normal position in the same manner as a spring arrangement.

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 ...
