Abstract

Uppfinningen hänförd sig till en fjäderupphängning för en hjulaxel till ett fordon, varvid fjäderupphängningen innefattar en fjäderlänk som är monterad till en fordonskropp på fordonet via ett fjäderfäste och ett axelfäste. Fjäderlänken innefattar en bladfjäder med en ögla i sin ena ände och är monterad till fjäderfästet via öglan. Öglan på bladfjädern är vänd nedåt i en vertikal fordonsriktning d. När fordonet utsätts för sidokrafter vid kurvtagning och kraften på fordonets hjulaxel därmed ökar i den vertikala fordonsriktningen d, så kommer fjäderlänken att deformeras i den vertikala fordonsriktningen dsamt i den horisontella fordonsriktningen dså att avståndet mellan öglans centrum och hjulaxeln minskar, vilket gör att en understyrningseffekt uppstår.(Fig. 2)The invention relates to a spring suspension for a wheel axle of a vehicle, the spring suspension comprising a spring link which is mounted to a vehicle body on the vehicle via a spring mount and an axle mount. The spring link comprises a leaf spring with a loop at one end and is mounted to the spring bracket via the loop. The loop on the leaf spring faces downwards in a vertical vehicle direction d. When the vehicle is subjected to lateral forces when cornering and the force on the vehicle's wheel axle thus increases in the vertical vehicle direction d, the spring link will be deformed in the vertical vehicle direction d as well as in the horizontal vehicle direction d so that the distance between the center of the loop and the wheel axle are reduced, causing an understeer effect to occur.(Fig. 2)
