摘要
为了越野车野外维修方便,提出了发动机和传动箱一体化设计的思路,此时需要全新的悬置方案.文中将发动机、传动箱及其辅助部件作为固联刚体,进行一体化悬置设计.具体内容包括:整体惯性参数的确定,悬置体等效线性化处理,悬置体的布置方式和极限工况强度的检验.其中悬置布置方案基于多自由度线性系统理论,通过配置弹性中心和垂直、俯仰和侧倾固有频率来实现.实车试验表明,提供的悬置方案满足工程使用要求.
The motor and transmission of off-road vehicles are considered as a unit for easy field operation. The motor, transmission and other auxiliary parts are fixed together, and a suspension is designed for the integration system. The contents include determining the inertia parameters, the linearization for the equivalent stiffness of the suspension, the arrangement of the suspension and the strength test on the extreme conditions. Based on the MDOFs linear theories, the suspension layout is obtained by configuring such parameters as the elasticity center, the vertical, pitch and roll natural frequencies. The road test of the vehicle shows that the designed suspension meets the requirements for engineering use.
