McPherson struts to Air-ride: Understanding different types of car suspensions
1 month ago | 5 Views
The McPherson strut is one of the most commonly used suspension systems, especially seen in modern front-wheel-drive cars. It is the most compact, lightweight and cost-effective solution making it popular among manufacturers. In this system, the shock absorber and coil spring are combined into a single unit. The McPherson strut provides good handling and comfort but is not ideal for high-performance driving as it can limit the tyre's movement.
A double wishbone suspension is a more advanced system, often found in sports cars. It consists of two U-shaped arms (upper and lower) that allow for greater control of the wheel's movement. This system offers better handling, especially during cornering and provides superior stability compared to the MacPherson strut. However, it is more complex, expensive and takes up more space.
Multi-link suspensions are typically used in performance cars. This system uses multiple arms (links) to control the wheel's movement independently, providing a high degree of flexibility and adjustability. Multi-link suspensions offer excellent handling, comfort, and stability, even at high speeds. However, they are costly and difficult to maintain due to their complexity.
Air suspension is commonly found in luxury vehicles. Instead of traditional springs, it uses air-filled bags controlled by a compressor. This system allows drivers to adjust the ride height according to their comfort. This system can also help with adaptability to various terrains. Air suspensions provide a smooth ride and better load levelling, but they are expensive and more prone to breaking down, ultimately requiring more maintenance.
Leaf springs are one of the oldest types of suspension systems and are still widely used in trucks, SUVs and commercial vehicles. This system consists of several layers of metal strips (called leaves) stacked together to absorb shocks. Leaf springs are simple, durable and capable of supporting heavy loads, but they provide a jumpier ride compared to more modern suspension systems.
