The invention relates to the technical field of automobile parts, and discloses a steel plate spring suspension. The suspension comprises a plate spring, a first support and a second support; the first support and the second support are arranged at the two ends of the plate spring, and the plate spring comprises a first spring steel plate and a second spring steel plate which are stacked up and down and connected with each other. The position, close to the first support, of the first spring steel plate is provided with an upwards-arched arch-shaped section, so that a distance is formed between the arch-shaped section and the second spring steel plate. According to the steel plate spring suspension, resonance with an automobile can be reduced, and comfort is improved; the steel plate spring suspension system can have the characteristic of variable stiffness; compared with the prior art, larger external force can be borne and buffered.

    本发明涉及汽车零部件技术领域,公开了一种钢板弹簧悬架,包括板簧和设置于所述板簧两端的第一支架和第二支架,所述板簧包括上下叠置且互相连接的第一弹簧钢板和第二弹簧钢板,所述第一弹簧钢板靠近所述第一支架的位置具有向上拱起的拱形段,使得所述拱形段与所述第二弹簧钢板之间具有距离。本发明的钢板弹簧悬架,能够减少与汽车自身发生的共振,提高舒适性;还能够使钢板弹簧悬架系统具有变刚度的特性,与现有技术相比,能够承载和缓冲更大的外力。
