Question

With the help of a proper layout, show the classification of suspension springs. Explain torsion bar spring.

Hint:

Tip: Torsion bar = straight bar that twists to absorb shocks!

Answer 1

Classification of Suspension Springs:
Suspension springs are used to absorb road shocks and provide a smooth ride.
They can be classified as follows:
1. Leaf Springs:
- Semi-Elliptical
- Quarter Elliptical
- Three-Quarter Elliptical
- Full Elliptical
- Transverse Leaf Spring
2. Coil Springs:
- Helical Coil Spring
3. Torsion Springs:
- Torsion Bar Spring
4. Air Springs:
- Air Bags or Bellows
5. Rubber Springs:
- Rubber Blocks
Explanation of Torsion Bar Spring:
A torsion bar spring is a type of straight bar that acts as a spring by twisting along its axis.
One end of the bar is attached firmly to the vehicle frame, while the other end is connected to a lever arm linked to the wheel hub.
When the wheel moves up and down due to road irregularities, the lever twists the torsion bar.
This twisting motion provides the necessary spring action to absorb shocks and maintain ride comfort.
Torsion bar springs are compact, adjustable, and commonly used in front suspension systems of many vehicles.
