The invention relates to a two-leaf spring blind hole structure, a balanced suspension and a vehicle. The two-leaf spring blind hole structure comprises a first leaf spring, a second leaf spring and a third leaf spring, a first blind hole is formed in the top of the first leaf spring, a first gasket is arranged at the top of the first leaf spring, a first through hole is formed in the first gasket, and the first through hole and the first blind hole are coaxially arranged; one end of the first positioning pin penetrates through the first through hole and is positioned in the first blind hole; the second leaf spring is located at the bottom of the first leaf spring, a second gasket is arranged at the bottom of the second leaf spring, and a second through hole is formed in the second gasket; and one end of the second positioning pin is embedded into the second through hole and is flush with the top surface of the second gasket, and the other end of the second positioning pin penetrates out of the second through hole. A traditional center hole structure is changed into a blind hole structure, full punching is avoided, the problem that a traditional plate spring center hole is broken frequently is solved, and the fatigue life of the plate spring is prolonged.

    本申请涉及一种两片簧盲孔结构、平衡悬架及车辆,其包括:第一片板簧,所述第一片板簧的顶部开设有第一盲孔,所述第一片板簧的顶部设置有第一片衬垫,所述第一片衬垫开设有第一通孔,所述第一通孔与所述第一盲孔同轴设置;第一定位销,所述第一定位销的一端贯穿所述第一通孔,并位于所述第一盲孔内;第二片板簧,所述第二片板簧位于所述第一片板簧的底部,且所述第二片板簧的底部设置有第二片衬垫,所述第二片衬垫开设有第二通孔;第二定位销,所述第二定位销的一端嵌入所述第二通孔内,并与所述第二片衬垫的顶面相平齐,另一端穿出所述第二通孔。将传统中心孔结构改为盲孔结构,避免全打孔,解决传统板簧中心孔频繁断裂,提高板簧疲劳寿命。
