两级扭杆弹簧的结构设计与计算

The structural design and the modeling of two-grade torsion bar

现代的汽车设计中,舒适性越来越被重视。对汽车平顺性的要求也越来越高。特别是对客车和卡车的舒适性要求逐渐提高,单级扭杆弹簧悬架已很难满足人们对舒适性的要求。介绍扭杆弹簧的一种新结构,这种弹簧分为两级,其刚度为变刚度,能有效地提高弹簧的性能。还给出了两级扭杆弹簧的设计方法和实例计算。

The comfort is value more and more in the design of automobile, It is also more and more important to the smoothness of a vehicle. The comfort of the passenger car and the truck is especially important, The single class torsion bar springhas already can hardly satisfypeople＇s request to the comfort .Introduce a new structure of torsion bar spring here that with a varing stiffiness, this kind of spring is divided into two classes. It can improve the performance of torsion bar spring. Introduced the design methods of two-gread toting bar spring here,and done a calculaition
