Pitkittäisjousitettu

Pitkittäisjousitettu refers to a type of suspension system used in vehicles, particularly in older or simpler designs. The term is Finnish and translates to "longitudinal sprung." In this configuration, the spring elements are oriented along the length of the vehicle, typically running from front to back. This contrasts with transverse suspension systems where springs are mounted across the width of the vehicle. Pitkittäisjousitettu suspension often involves leaf springs, which are composed of multiple layers of metal strips stacked together. These springs are attached to the axle and the vehicle chassis, allowing for vertical movement of the wheels while absorbing shocks from the road. While less common in modern passenger cars due to advancements in independent suspension systems, pitkittäisjousitettu designs can still be found in some trucks, trailers, and agricultural machinery where durability and simplicity are prioritized. The longitudinal orientation can influence the vehicle's handling characteristics, particularly its ride comfort and stability under acceleration and braking. The simplicity of the design often translates to lower manufacturing costs and ease of maintenance.
