Research on the Influence of Charging Oil Conditions on the Axial Force of Hydraulic Torque Converter

The hydraulic torque converter is a critical component in high-power tracked vehicles such as bulldozers or bridge machines. Its axial force has significant impact on the reliability and load-carrying capacity of transmission system, which greatly influenced by charging oil conditions. To investigate characteristic its effects, computational fluid dynamics (CFD) method established considering inner outer leakage regions, well inlet outlet channels. Additionally, novel force-testing proposed, testing validation experiments prototype have been completed. research findings reveal that changes viscosity resulting from variations temperature considerable converter. pump turbine decreases increases due to varying pressure sensitivity among different components. influence follows linear relationship, with magnitude determined unbalanced area during design development. In addition, formula for proposed under pressures. Furthermore, suppression without altering structure, validated an effective method. results lay theoretical foundation forces converters, they also engineering application value high-reliability long-life converters.
