Types Of Suspensions Systems

The suspension system is divided into the following categories:

Double Wishbone Suspension

The Double Wishbone suspension also has an independent design, so the turning angle and suspension movement will not affect the geometry angle, because the angle will remain constant. This suspension is fairly easy to get damaged in its parts, such as broken ball joint at the bottom or top, long tie rod, and end tier rod. To avoid various damage to the car, you can do spooring regularly.

Double Wishbone Suspension

Pros

  • Precise handling
  • Good control over angles

Cons

  • Complex
  • Limited space

Multi-Link suspension combines Double Wishbone and Multi-Link, making it intricate with separate parts connected by joints. It control wheel forces for good grip. However, if it gets damaged, fixing it takes time, and the parts are hard to find, making it pricier than other suspensions.

Multi-Link Suspension

Pros

  • Balance between comfort and handling
  • Tuning flexibility

Cons

  • Complex
  • Increased weight

Rigid Axle Suspension

Rigid Axle suspension is typically found at the rear of a car. It has two wheels on the rear. It is connected to a single axle. There are two types of Rigid Axle suspension:

  • With leaf springs
  • With coil springs, often called just “springs.”

Axle Rigid suspension is simple and sturdy. It absorbs road shocks for a smooth ride. Different car brands have unique suspension setups. Some types are commonly used in modern cars.

Rigid Axle Suspension

Pros

  • Simplicity
  • Lower cost

Cons

  • Poor handling
  • Limited articulation

Macpherson Suspension

Macpherson suspension is named after Earle Macpherson. Automakers favor it due to its affordability and simple components. Macpherson suspension has an upright design supported by shock absorbers, making it easily accessible. It struggles with heavy loads. It changes its tilt angle during turns. It also affects tire grip on the road.

Macpherson Suspension

Pros

  • Simple
  • Space-efficient

Cons

  • Limited adjustability
  • Body roll

Independent Suspension

Independent suspension is a unique design where the rear wheels aren’t directly connected, allowing one wheel to move without affecting the other. This suspension is found in luxury cars. This is due to its complexity and independent axle movements. This is made possible by two flexible joints. For example, the Wuling Cortez CT Type S offers this comfort in its rear wheels, making both drivers and passengers in the back seat enjoy a comfortable ride.

Independent Suspension

Pros

  • Improved comfort
  • Better traction

Cons

  • Complexity
  • Maintenance

Rigid suspension – Leaf Spring

Rigid – Leafspring suspension is commonly seen in cars in Indonesia, especially in commercial or older models, often used at the rear due to its stiffness. It has a straightforward construction with an Axle Housing connected to the frame using a U-Bolt, offering good durability.

Rigid suspension - Leaf Spring

Pros

  • Simple
  • Durable

Cons

  • Limited comfort
  • Less precise

Trailing Arm Suspension

Trailing Arm suspension is similar in appearance to 3 Links – Rigid but operates differently. It connects from the right to the left. It is typically placed at the rear of the car.

Trailing Arm Suspension

Pros

  • Stability
  • Simplicity

Cons

  • Limited adjustability
  • Axle hop

Air Suspension

Air Suspension is a high-performance suspension. It is found mainly in luxury cars. It can be computer-adjusted for precise settings. It has a complex construction and comes at a high cost compared to other suspensions.

Air Suspension

Pros

  • Adjustable height
  • Load-leveling

Cons

  • Complex maintenance
  • Reliability issues
