本文论述“主动底盘系统”范畴内两个最现实的问题:悬架减振及四轮转向。关于悬架减振,首先探讨传统悬架的规律,然后阐述主动和半主动悬架系统对悬架可能作出的改进。对所谓“悬空阻尼”系统,着重作了介绍。四轮转向方面首先论述了比例四轮转向、质心侧偏角补偿和可调节的四轮转向等几种基本型式的理论基础。接着介绍了现有的四轮转向系统。
This article discusses two of the most realistic issues in the category of “Active Chassis Systems”: suspension damping and four-wheel steering. With regard to suspension damping, the law of the traditional suspension is first discussed, and then the possible improvements to the suspension of the active and semi-active suspension systems are described. The so-called “dangling damping” system, mainly introduced. In the four-wheel steering aspect, the rationale of several basic types of four-wheel steering, four-wheel center-of-gravity compensation and adjustable four-wheel steering are first discussed. Then introduced the existing four-wheel steering system.
