The invention relates to a two-leaf spring structure, a balanced suspension and an automobile, and belongs to the field of two-leaf springs. Wherein the two leaf spring structures comprise a first leaf spring, and a first center hole is formed in the top of the first leaf spring; a second center hole is formed in the bottom of the second leaf spring, and a third center hole is formed in the top of the second leaf spring; one end of the connecting piece is connected with the first center hole, and the other end of the connecting piece is connected with the second center hole; and the cover plate is provided with a first positioning pin, the first positioning pin is inserted into the third center hole, the cover plate is further connected with a fixing assembly, and the fixing assembly is used for fixing the cover plate to the balance bearing hub. The design of a center through hole is omitted, the first center hole is formed in the top of the first leaf spring, the second center hole is formed in the bottom of the second leaf spring, and the third center hole is formed in the top of the second leaf spring, so that the problem of stress concentration can be reduced, and the overall structural strength is improved.

    本申请涉及一种两片簧结构、平衡悬架及汽车,属于两片簧领域。其中两片簧结构包括第一片簧,其顶部设有第一中心孔;第二片簧,其底部设有第二中心孔,其顶部设有第三中心孔;连接件,其一端与所述第一中心孔连接,另一端与所述第二中心孔连接;盖板,其上设有第一定位销,所述第一定位销插装在所述第三中心孔内,所述盖板上还连接有固定组件,所述固定组件用于将所述盖板固定在平衡轴承毂上。本申请取消中心通孔的设计,通过在第一片簧顶部设置第一中心孔,在第二片簧底部设置第二中心孔以及在其顶部设置第三中心孔,能够减少出现应力集中的问题,提升整体结构强度。
