Kaksoisjousitus

Kaksoisjousitus, known in English as double wishbone suspension, is a type of independent suspension system used in vehicles. It consists of two wishbone-shaped arms that pivot at the chassis and control the movement of the wheel hub. Each wishbone arm is typically connected to the chassis at two points and to the wheel hub at one point. This arrangement allows the wheel to move up and down while maintaining a consistent alignment relative to the road surface.

The primary advantage of a double wishbone suspension is its ability to control wheel geometry during suspension travel. The geometry can be designed to minimize changes in camber (the angle of the wheel relative to the vertical) and caster (the angle of the steering axis relative to the vertical) during compression and rebound. This leads to improved handling, better tire wear, and a more stable ride. The double wishbone design also offers a good balance between ride comfort and sporty performance.

This suspension system is commonly found in performance cars, sports cars, and racing vehicles where precise control over wheel alignment is crucial for optimal handling. It is also used in some heavy-duty trucks and off-road vehicles due to its robust construction and ability to handle significant loads. The complexity and cost of manufacturing can be higher compared to simpler suspension types like MacPherson struts.
