Abstract
Differential gear backlash and drive shaft backlash are considered important items affecting vehicle performance because they directly affect the vehicle tip-in shock and drivability. However, they are not usually standardized and correctly managed. Thus, new differential gear backlash measuring equipment that could quantify the total differential gear backlash, including drive shaft, need to be developed. From an analysis of 600 test results, it was found that the total differential gear backlash changed according to the gear size, contact position of the side gear and pinion gear tooth, and thickness of the shim. Additionally, the total differential gear backlash was smaller than the drive shaft backlash in driveline. Using a correlation check of the design specifications and experimental values, the total differential gear backlash that can generate tip-in shock in the vehicle could be predicted during the early design stage. This design prediction can also be used for a new reducer for the electric vehicle.
