Suspension systems

Suspension Systems Overview

  • The suspension system is a critical component of a vehicle’s chassis.
  • Its primary role is to isolate the body and passengers from the vibration and shocks caused by the road irregularities.
  • Suspension system is responsible for providing better control over the car by maintaining the tyres in constant contact with the road surface.

Types of Suspension Systems

Leaf Spring Suspension

  • The leaf spring suspension system is one of the oldest types of suspension systems.
  • This system comprises several layers of metal (known as leaves) stacked together.
  • The resilience of these metal leaves provides the necessary suspension effect.

Coil Spring Suspension

  • The coil spring suspension system is the most common type of suspension system found in modern vehicles.
  • It comprises a heavy-duty coiled metal spring, which is installed between the axle and the vehicle’s body.
  • It absorbs the vertical energy from the road irregularities, delivering a smoother ride.

Air Suspension

  • The air suspension system uses air-filled bags instead of springs to maintain the vehicle’s height and to absorb road shocks.
  • This system offers superior ride quality and is adjustable, allowing the ride height to be changed according to load requirements.

Key Components of a Suspension System

  • Springs: The core component that absorbs the energy from road shocks to soften their impact.
  • Shock Absorbers: Also known as dampers, they control the movement of springs and suspension, reducing oscillations.
  • Anti-roll Bars: These components link the left and right suspension units, reducing body roll while cornering.

Role of the Suspension System

  • Shock Absorption: This is the system’s key role, enhancing ride comfort by absorbing the jolts from surface irregularities.
  • Handling Stability: By maintaining tyre contact with the road, the suspension system provides better handling and control.
  • Consistent Tyre Contact: Ensuring that the tyres remain in consistent contact with the road means improved traction and safety.

By understanding the components, operation and importance of suspension systems, you’ll gain an essential grasp on the factors affecting vehicle suspensions.
