Outline
To address the technical challenges in the configuration design of in-wheel drive corner modules, including strong coupling between large-angle wheel steering and suspension kinematics, high propensity for component motion interference, and degradation of Kinematics and Compliance (K&C) characteristics, the paper conducts a comparative analysis of mainstream corner module configurations in the industry to clarify their respective technical features and application scenarios. A kingpin-series integrated corner module based on kingpin steering and double-wishbone suspension is proposed accordingly. The design of a drive-brake integrated in-wheel electric wheel is completed, and the matching of a top-mounted kingpin steering power unit is realized. The suspension hardpoint layout and system integration are finished in accordance with the three-plane suspension design criterion. The results of iterative K&C simulation optimization and Digital Mock-Up (DMU) motion verification indicate that after optimization, key indicators such as bump steer, bump camber, wheel travel base and track change all meet the design specifications. No component motion interference occurs within the full steering angle range of-30° to 90°, which effectively solves the problems of component interference and K&C characteristic degradation caused by the coupling between large-angle steering and suspension.
