The results of determining the axial forces acting on the supports of the experimental torque converter

Abstract

The article presents the methodology and results of experimental studies of the parameters of the torque converter to determine the axial forces acting on the supports of torque converters with a centripetal turbine. During the experiment, the values of axial forces without discharge holes in the turbine wheel disk were determined, it was revealed that the axial forces in this torque converter reach a significant value, which can negatively affect the performance of the torque converter. To reduce the axial forces in the hub of the turbine wheel of the torque converter, the influence of the discharge holes made in the disk of the turbine wheel on the magnitude of the axial forces was estimated, studies have shown that the discharge holes significantly reduce the magnitude of the maximum axial forces, while maintaining the qualitative dependence of the axial forces for different revolutions, pressure and temperature. For each of the stages, the complete control external characteristics of the torque converter were removed.
