The purpose of this study is an analysis of propeller shaft torque capability in the quick start for heavy duty vehicle. Domestic commercial vehicle market compared to Europe or the United States is considerably smaller scale. Technologies levels of commercial vehicle are also tailored to the domestic market. Particularly, commercial vehicles on the power-train system is insufficient research to prepare for passenger car or SUV. Quick Start test is applied in heavy duty commercial vehicles, the vehicle carrying the maximum load that can be loaded conditions(GVW) instantaneously increasing engine speed from the start more than a certain number of times the test is performed repeatedly. In this study, theoretical calculations of the torque and the actual vehicle delivered under propeller shaft torque measured and compared with theoretical design values for the driveline is to ensure the reliability.
