The knuckle of the in-wheel system functions as a knuckle of the conventional vehicle and a housing for supporting the reducer and the motor. In-wheel knuckle should maintain rigidity against deformation by the motor and reducer during inwheel operation in order to ensure NVH performance, also in order to secure the vehicle R&H performance, it should be designed to support load from wheel, secure stiffness and reduce the unsprung mass. In this thesis, we performed the lightweight of knuckle in in-wheel system with motor and reducer by using topology optimization. After the optimization, we verified the static strength and stiffness analysis through finite element analysis and compared the transmission error through the gear analysis program and then we could check the effectiveness of the lightweight design. As a result of comparison between before and after, we confirmed stiffness securement and weight reduction.
