Study  on  Torque  Converter  Blades  Parameters  by Sensitive  Parameter  Analysis

Abstract

Abstract:

In automobile and engineering vehicle transmission system,the blade design of hydraulic torque converter was of always difficulty.By the use of DOE technology,the blade import and export angle,deviation angle and loss coefficient were studied as the sensitive parameters of hydraulic torque converter.Their influences on the peak efficiency,starting torque ratio and torque coefficient were synthetically considered.Finally,the influence trend among these parameters was obtained,the specific domains of the influencial factors were confirmed.The influence trend was verified by relevant tests,based on the change of the import angle of the pump impeller.It has important guiding significance on converter optimization.

Key words: hydraulic , torque , converter;blade;sensitive , parameter;design , of experiment(DOE) , technology
