摘要针对轮毂电机占用轮内空间，导致前悬架无法布置的问题，以麦弗逊式悬架为基础，将原来的单个下控制臂改为两个独立的控制臂，得到了适合轮毂电机驱动的新的悬架构型。建立了新型悬架系统前轮定位参数的理论计算模型和多体动力学模型，并进行了分析验证。通过新型悬架系统硬点位置优化设计，得到合适的前轮定位参数。该悬架构型为轮毂电机提供了足够的轮内空间，设计灵活，并且能最大限度的沿用麦弗逊式悬架的部件，解决了传统悬架不适合轮毂驱动的难题。

Abstract：Due to the in-wheel space occupied by in-wheel motor, the traditional front suspension cannot be installed. Therefore, a new suspension system for in-wheel motor driving is developed by changing the McPherson suspension’s single lower control arm to two separate control arms. The theoretical model and multi-body dynamic model are built and analyzed respectively. Through the optimization of the hard point locations of the new suspension system, the suitable front suspension parameters are obtained. The new suspension is flexible to design and supplies enough space for installation of in-wheel motor. Meanwhile, most of the original components can be carried over.

Key words： suspension type in-wheel motor driving suspension parameters
