Classification of Suspension Springs:
Suspension springs absorb road shocks, ensuring a smooth ride. They are 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 straight bar that functions as a spring through twisting along its axis. One end attaches securely to the vehicle frame, while the other connects to a lever arm linked to the wheel hub. As the wheel moves in response to road variations, the lever twists the torsion bar. This twisting action generates the required spring effect to absorb shocks and maintain ride comfort. Torsion bar springs are compact, adjustable, and frequently used in the front suspension systems of numerous vehicles.
