Theoretical Calculations and Experimental Studies of Power Loss in Dual-Clutch Transmission of Agricultural Tractors

Recent carbon neutrality policies have led to active research in the agricultural tractor sector replace internal combustion engines, making it imperative minimize power losses improve efficiency. Dual-clutch transmissions (DCTs) been employed tractors primarily due their short shift time and smooth feel. However, DCTs a relatively large number of components complex structures owing spatial constraints, challenging predict losses. Therefore, DCT losses, this study defined oil churning by considering structural characteristics circulation comparing analyzing theoretical calculation test results at different levels. Power loss was calculated based on ISO standards fluid viscosity theory, tests were performed verify. We confirmed that consistency improved when reflecting lubrication state, features circulation. In addition, factors contributing under low- high-speed conditions analyzed calculating for each component.
