Design of Integrated Corner Module Simultaneously Meeting the Requirements of Mobility and Handling Stability

doi:10.3901/JME.2019.22.011

Abstract

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
