The invention discloses a design method of a main spring and an auxiliary spring of a steel plate spring suspension, a steel plate spring suspension system and a vehicle, in the design method of the steel plate spring suspension, the rigidity C1 of the main spring and the rigidity C2 of the auxiliary spring of the steel plate spring of the steel plate spring suspension meet the following formula: lambda is the ratio of sprung during full load to sprung during no load. According to the design method of the steel plate spring suspension, the steel plate spring suspension system and the vehicle, the rigidity C1 of the main spring can be reduced by increasing the proportion of the rigidity of the auxiliary spring of the steel plate spring, so that the smoothness of the vehicle during no load or less load is improved, the total rigidity (C1 + C2) of the steel plate spring is still kept large, the bearing range of the vehicle is widened, and the bearing capacity of the vehicle is improved.
本发明公开了一种钢板弹簧悬架主副弹簧的设计方法、钢板弹簧悬架系统及车辆,所述钢板弹簧悬架的设计方法中,所述钢板弹簧悬架的钢板弹簧的主簧刚度C1和副簧刚度C2,满足如下公式:其中,λ为满载时的簧载与空载时的簧载的比值。本发明的钢板弹簧悬架的设计方法、钢板弹簧悬架系统及车辆中,通过增大钢板弹簧副簧刚度的占比可减小主簧刚度C1,以提升车辆空载或少载时的平顺性,且使钢板弹簧总刚度(C1+C2)仍保持得较大,以拓宽汽车的承载范围,提升汽车的承载能力。
