Hydrostatic Power Split Transmission Test Band for Agricultural Tractor

Due to the advantages of continuously variable transmission and high efficiency, hydrostatic power-split transmission (HPST) shows the applicability on the agricultural tractor. This is also shown in some theoretical research results. However, practical tests are needed to evaluate the power-split transmission configuration for the operating principle and dynamics properties for the next design goal. This article introduces the experimental model (test band) of a HPST built at the Department of Dynamics, Vietnam National University of Agriculture. The test band consists of a drive motor, a HPST, load generator and modern data processing and measuring equipment. The model can be used to reproduce the operating principle and to study the static and dynamic properties of the HPST, as the basis for control strategies in working conditions of agricultural tractors.
