微型貨車鋼板彈簧的結(jié)構(gòu)設計與校核

 摘要：本次設計中首先介紹了鋼板彈簧的發(fā)展歷程并且對其未來的發(fā)展趨勢作出分析；然后分析了鋼板彈簧對汽車造成的影響有哪些，比如平順性和操作穩(wěn)定性等方面；接著根據(jù)鋼板彈簧各個結(jié)構(gòu)的優(yōu)缺點和具體車型的使用用途，對各主要零部件進行結(jié)構(gòu)上的選型和計算；

因為鋼板彈簧相較于其它的彈簧有結(jié)構(gòu)簡單，維修方便等優(yōu)點所以在載貨汽車上有普遍的應用。同時它的缺點是也使得它無法應用在獨立懸架的汽車上，明顯的缺點有鋼板彈簧懸架具有較大的重量，較為長的縱向尺寸，同時有較強的剛度，使得舒適性相對來說也是較差，并且鋼板彈簧懸架在與車架進行連接的部位也容易在使用中產(chǎn)生磨損。

在這次的設計中我們著重對微型貨車的鋼板彈簧進行結(jié)構(gòu)設計，通過計算并繪制出圖紙。

Structure design and check core of micro steel plate spring

Abstract：First, the paper introduces the development of leaf spring and analyzes its future development trend Then, it analyzes the influence of leaf spring on automobile, such as ride comfort and operation stability Then the detailed design steps and design requirements of leaf spring are described, and the structure selection and calculation of the main parts are made The arc height and curvature radius of the leaf spring are calculated, and the strength and stiffness of the material is checked and checked, and the steel spring is checked.

Because the leaf spring has the advantages of simple structure and convenient maintenance compared to other springs, it has a common application in the truck. At the same time, its disadvantage is that it can not be applied on the automobile

of the independent suspension, obvious disadvantage that the steel spring suspension has a larger weight, the longitudinal size of the radiation, and the stiffness is relatively poor, and the part of the steel spring suspension is easy to wear in use.

In this design, we focus on the structure design of the leaf spring of micro, calculate and draw the drawings.

Keywords：Micro； Sheet spring； Structural design； Check
