扭杆弹簧在行李箱盖系统中的设计与应用

摘要

Torsion-Bar Spring is a kind of spring with its one end fixed while the other end attaching to a working part, using torsion spring force to absorb vibration energy. The Torsion-Bar Spring is now widely utilized in the automobile industry. This article emphasizes on introducing how to match Torsion-Bar Spring with gooseneck hinge, also focuses on the design method and application condition as the assistance mechanism of opening the trunk lid in the development of automobile.%扭杆弹簧即为一端固定而另一端与工作部件连接的杆形弹簧，主要依靠扭转弹簧力来吸收震动能量。扭杆弹簧在汽车制造业已经有非常广泛的应用。重点介绍扭杆弹簧匹配鹅颈式铰链作为汽车行李箱盖开启助力机构，在汽车开发中的设计方法与应用。
