| 초록 |
As electric vehicles (EVs) increasingly prioritize energy efficiency, minimizing torque loss in drivetrain components has become essential. The Cross-Groove Joint (CGJ), commonly applied in rear-wheel-drive (RWD) EVs, offers the potential for high torque transmission efficiency by reducing backlash and internal friction through its compact and constrained structure. This study investigates the primary causes of torque loss within CGJs—specifically focusing on rolling and sliding behavior of the internal ball elements—and evaluates the influence of three key design parameters: cage window height (Hcw), pitch circle diameter (P.C.D) difference, and groove conformity (Cf.). Based on simulation and test results, an optimized design guideline is proposed for improving torque efficiency in CGJs applied to RWD EVs. |
