The invention discloses a steel plate spring suspension and a vehicle. The leaf spring suspension comprises a main piece and an auxiliary piece. The main leaf includes at least two first leaf springs stacked in a height direction. The auxiliary piece is located on the lower side of the main piece, the length of the auxiliary piece is smaller than that of the main piece, the auxiliary piece comprises at least one second steel plate spring, the first steel plate spring and the second steel plate spring are both arched plates protruding downwards, and the bending radian of the second steel plate spring is greater than that of the first steel plate spring. In the first working state, a gap is formed between the end part of the auxiliary sheet and the main sheet, so that the end part of the auxiliary sheet is not contacted with the main sheet; in the second working state, the end of the auxiliary piece makes contact with the main piece. The bending radian of the second steel plate spring of the auxiliary piece is larger than that of the first steel plate spring of the main piece, the variable stiffness stroke of the suspension is controlled through the radian of the auxiliary piece, and the vehicle stability is improved.

    本发明公开了一种钢板弹簧悬架和车辆。钢板弹簧悬架包括主片和副片。主片包括在高度方向上层叠布置的至少两个第一钢板弹簧。副片位于主片的下侧且副片的长度小于主片的长度,且副片包括至少一个第二钢板弹簧,第一钢板弹簧和第二钢板弹簧均为朝下凸的拱形板,且第二钢板弹簧的弯曲弧度大于第一钢板弹簧的弯曲弧度,在第一工作状态,副片的端部与主片之间具有间隙以使得副片的端部与主片不接触;在第二工作状态,副片的端部与主片接触。副片的第二钢板弹簧的弯曲弧度大于主片的第一钢板弹簧的弯曲弧度,通过副片的弧度控制悬架的变刚度行程,提高车辆稳定性。
