摘要: 配备独立转向系统的分布式驱动电动汽车在底盘动力学控制及机动性能方面具有突出的优势,然而悬架几何运动学特性与车轮大转向角之间的矛盾使得常规悬架系统结构已经无法满足分布式驱动电动汽车操纵稳定性与高机动性的双重需求。论文提出轮边集成底盘系统新型悬架结构方案,对悬架系统进行刚度、几何运动学以及零部件结构设计,并为其匹配转向系统和轮内驱动系统。通过运动干涉检查验证轮边集成底盘系统能够满足高机动性需求。对照常规双横臂悬架,考察了新型悬架的几何运动学特性与整车的侧向动力学特性,仿真验证了轮边集成底盘系统能够满足操纵稳定性需求。

Abstract: Distributed drive electric vehicles equipped with independent steering system have outstanding advantages in chassis dynamics control and mobility. Faced with the requirements of the handing stability and high mobility of this type of electric vehicles, the contradiction between the change of the kinematics parameters of the suspension and the large steering angle makes the conventional suspension steering mechanism unable to meet the application requirements. Therefore, an integrated corner module with new suspension is proposed. The suspension system is subjected to the design process of stiffness, kinematics and structural, and matched with new type steering system and in-wheel drive system. The integrated corner module system is verified by motion interference checking to meet high mobility requirements. Comparing with the double wishbone suspension, the vehicle lateral dynamics characteristic is investigated. The test results show that the new suspension system can meet the requirements of handing stability.

Key words: distributed drive electric vehicles, integrated corner module, suspension system design, mobility, handling stability
