毕业设计-10吨载重汽车悬架系统设计，共52页，17269字，一个总装图，七个零件图。
摘要
汽车悬架是车架（或车身）与车轴（或车轮）之间的弹性联结装置的统称。它的作用是传递作用在车轮和车架之间的力和力扭，并且缓冲由不平路面传给车架或车身的冲击力，并衰减由此引起的震动，以保证汽车能平顺地行驶，同时也能保证货物完好和人员的舒适。汽车的悬架系统主要由弹性元件、减振器和导向机构组成。
由于本课题的设计是载重的汽车，主要以货车的悬架为设计对照车型，因此本课题所选择的弹性元件是多片钢板弹簧。再选择钢板弹簧外表形式，同时选择相对应合适的固定机件。本文根据10吨的整车质量算出单侧钢板弹簧所要承受的载荷，再根据所求得的载荷量去计算出钢板弹簧的基本参数（钢板弹簧的厚度、宽度和长度）。并根据所得到的基本参数去求钢板弹簧刚度和强度，最后根据所选用的计算方法去计算出钢板弹簧的弧高和半径曲率。并由以上参数画出钢板弹簧。
在前悬架里加装减振器，首先根据减振器的工作性能确定工作缸、储液缸的内径和缸厚。再根据一些标准定选好各种零件的参数。

10 tons of truck suspension system design
ABSTRACT
Vehicle suspension is collectively referred to the flexible connect devices between the frame (or body) and the axle (or wheel). The suspension system use’s to transmit the role of the wheels and frame and between the torsion force, and uneven pavement from the buffer to the frame or body of the impact. It can make sure the truck travel smooth-going, also to ensure the comfort of goods and personnel intact. Automobile suspension system is mainly composed of flexible components, shock absorber and guidance agencies.
Since this is sue is designed for heavy-duty vehicles, truck is the main model, multi-piece leaf spring is selected as the same time to choose the right corresponds to a fixed mechanical. At the article 10 tons in accordance with the quality of work out side of the vehicle leaf spring to load, and then obtained based on the amount of load to calculate the basic parameters of leaf springs (spring steel plate thickness, width and length). And on the basis of the basic parameters to leaf springs for stiffness and strength, the final selection based on the calculation method to calculate the arc of the leaf springs and radius of curvature high. Parameters drawn from the above leaf spring.
The installation of the first shock absorber in suspension, the first performance under the shock absorber cylinder identification, reservoir tank and the cylinder diameter thick. Standard based on some selected parameters of the various parts.
Key words: elastic components; leaf spring; shock absorber
