Bilfjæring

Bilfjæring, or automotive suspension, refers to the system of springs, shock absorbers, and linkages that connects a vehicle's wheels to its chassis. Its primary purpose is to absorb road imperfections, ensuring a comfortable ride for occupants and maintaining tire contact with the road surface for optimal traction and handling.

The basic components of a suspension system include springs, which absorb the initial impact of bumps, and dampers (often called shock absorbers), which control the oscillations of the springs. Linkages and arms are also crucial, guiding the wheels' movement and ensuring they remain properly aligned.

Various types of suspension systems exist, each with its own advantages and disadvantages. Common types include independent suspension, where each wheel can move vertically without directly affecting the opposite wheel, and dependent suspension, where the wheels are connected by a solid axle and move together. MacPherson struts and multi-link suspensions are popular forms of independent suspension found in many modern vehicles.

A well-designed suspension system balances ride comfort with vehicle control. It influences factors such as steering response, braking stability, and the overall driving experience. The choice of suspension design is often dictated by the vehicle's intended use, with sports cars prioritizing handling and luxury vehicles emphasizing a smooth ride. Regular maintenance of suspension components is important for ensuring safety and performance.
