A suspension system is a series of components that connect a vehicle's body or chassis to its wheels. Its main function is to absorb the shocks and vibrations that occur as the vehicle travels. It also helps to maintain the stability and control of the vehicle, ensuring that it can be safely and comfortably driven.
There are two main types of suspension systems: air systems and leaf systems. Air systems use air-filled bags or bellows to provide the necessary cushioning and support, while leaf systems use metal springs or leaf springs. Both types of systems have their own advantages and disadvantages. At Placer Fleet Services, we offer comprehensive mobile suspension maintenance and repair services.
Air Suspension Systems
Air suspension systems are commonly found on heavy-duty trucks vans and buses. They use pressurized air, rather than metal springs, to provide the necessary support and cushioning. Air suspension systems have a number of benefits, including:
- Adjustability: Air suspension systems are highly adjustable, allowing you to fine-tune the ride height and firmness of your vehicle to suit your preferences or specific needs. This can be especially useful for vehicles that need to carry heavy loads or operate in rough terrain.
- Comfort: Air suspension systems offer a smooth and comfortable ride, as they are able to adapt to road conditions and absorb shocks and vibrations more effectively than traditional metal spring systems.
- Greater load capacity: Air suspension systems are able to carry heavy loads with ease, as they can be inflated to increase their support and stability. This makes them ideal for use on heavy-duty vehicles, such as trucks and buses.
- Durability: Air suspension systems are generally more durable than traditional leaf spring systems, as they have fewer moving parts and are less susceptible to wear and tear.
However, air suspension systems also have some drawbacks. They require more maintenance than leaf spring systems, as the air bags or bellows need to be regularly checked for leaks and replaced if necessary. They operate based on commands sent by the ECU and as such can require specialized diagnostics to identify issues.
Leaf Spring Suspension Systems
Leaf spring suspension systems are quite common in trucks, SUVs, delivery vehicles and vans. They use metal springs, known as leaf springs, to provide the necessary support. Leaf spring systems have a number of benefits, including:
- Cost: Leaf spring systems are generally cheaper to manufacture and repair than air suspension systems, as they have fewer moving parts and the springs are more readily available.
- Simplicity: Leaf spring systems are relatively simple in design and operation, making them easy to maintain and repair.
- Weight: Leaf spring systems are generally lighter than air suspension systems, which can be beneficial for vehicles that need to carry heavy loads or operate in rough terrain.
However, leaf spring systems also have some drawbacks. They are not as adjustable as air suspension systems, so it can be difficult to fine-tune the ride height and firmness. This can result in a more uncomfortable ride for drivers. Because of their composition, they are also more susceptible to cracks and rust.
