The invention discloses an automobile steel plate spring and spiral spring combined suspension, and relates to the technical field of automobile chassis integral bridge suspension systems. The steel plate spring and spiral spring combined suspension comprises a spiral spring (3) and a shock absorber (4) which are installed on an integral bridge (5), a steel plate spring (2) is installed on the outer side of the spiral spring (3), and the rear end of the steel plate spring (2) is connected with a vehicle bottom girder through a folding arm lifting lug (1). The folding arm lifting lug can be flexibly unfolded and folded within a certain range, so that when the vehicle is in light load, the folding arm lifting lug is in an unfolded state, the comfort is improved through load bearing and shock absorption of the spiral spring, and if the off-road vehicle is in the off-road process, the folding arm lifting lug can provide a large stroke between wheels and a vehicle frame, and the stability of the off-road vehicle is improved. When the vehicle has a large load capacity, (1) the limiting stopper of the lifting lug of the folding arm is in a folded state, the steel plate spring and the spiral spring bear and absorb shock together, and the characteristic of high load capacity of the existing steel plate spring is retained;

    一种汽车钢板弹簧与螺旋弹簧组合的悬架,涉及汽车底盘整体桥悬架系统技术领域。该钢板弹簧与螺旋弹簧组合的悬架包括(5)整体桥上安装的(3)螺旋弹簧与(4)减震器,(3)螺旋弹簧外侧安装(2)钢板弹簧,(2)钢板弹簧后端由(1)折叠臂吊耳连接车底大梁。(1)折叠臂吊耳在一定范围内可以灵活的张开与合拢,使车辆在轻载重量的时候(1)折叠臂吊耳是张开状态,由螺旋弹簧承重和减震提高舒适性,如果是越野车在越野过程中,(1)折叠臂吊耳能够提供给车轮与车架之间较大行程,提高越野车的稳定性。车辆在大载重量的时候(1)折叠臂吊耳的限位器是合拢状态由钢板弹簧与螺旋弹簧一起承重和减震,保留现有钢板弹簧载重强的特点。
