pitkittäisjousitetut

Pitkittäisjousitetut refers to a type of suspension system used in vehicles, particularly in rear axles. The term translates from Finnish to "longitudinal sprung." In this configuration, the suspension springs are oriented lengthwise along the vehicle's chassis. This design is commonly found in older vehicle designs and some commercial vehicles.

The primary function of a pitkittäisjousitettu system is to absorb road shocks and vibrations, ensuring a smoother ride and maintaining tire contact with the road surface. The springs, typically leaf springs, are attached at both ends to the chassis and the axle. As the wheel encounters uneven terrain, it moves vertically, causing the spring to compress or extend, thus dampening the impact.

One of the characteristics of this suspension type is its relative simplicity and robustness. It is often chosen for its durability and ability to handle heavy loads, making it suitable for trucks and trailers. However, compared to more modern suspension designs, pitkittäisjousitetut systems can offer less precise handling and a more pronounced tendency to roll in corners. The longitudinal arrangement can also influence the vehicle's handling dynamics, particularly under acceleration and braking. Despite its limitations, its straightforward construction and cost-effectiveness have ensured its continued use in specific applications.
