【 摘 要 】

This paper performs an analysis of the drawbar pull influence over the power flow within the automotive transmissions. First part of the work presents a serial of theoretical approaches with respect to the analyzed elements. Second part of the paper reveals the vehicle's instrumentation to achieve the experimental data and some of the research results as well. The final part of the paper draws a series of conclusions with respect to mode the power loop's magnitude is influenced by the general drawbar pull. Last, but not least, technical solutions are introduced to decrease the power loops and contribute to the fuel savings.
