pitkittäisjousitettujen

Pitkittäisjousitetut refers to a specific type of suspension system used in vehicles. The term originates from Finnish, where "pitkittäis" means longitudinal or lengthwise, and "jousitetut" means sprung. Therefore, pitkittäisjousitetut suspension systems are characterized by springs that are oriented longitudinally along the vehicle's chassis.

In a pitkittäisjousitettu system, the spring is mounted to lie parallel to the direction of travel. This contrasts with transverse spring systems, where the spring is mounted perpendicular to the direction of travel. The precise design and implementation of pitkittäisjousitetut suspension can vary. Common examples include the use of leaf springs or coil springs arranged in this longitudinal manner.

The primary function of any suspension system, including pitkittäisjousitetut, is to absorb shocks and vibrations from the road surface, thereby improving ride comfort and ensuring tire contact with the ground for better handling and stability. The longitudinal orientation of the springs influences how forces are transmitted and absorbed, affecting the vehicle's dynamic behavior. This type of suspension can be found in various types of vehicles, historically and in some modern applications, particularly in rear axle configurations. The specific advantages and disadvantages depend on the overall suspension geometry and the type of spring used.
