Development of a rational model range of hydrodynamic torque transformers based on their key parameters: existing approaches overview

Abstract

Introduction (problem statement and relevance). Today's scientific papers on hydrodynamic torque transformers are related to the topic of optimising their design in order to decrease the cost of manufacture with improvement or insignificant degradation of transforming properties and fuel economy at the same time. However, no attention is paid to the issue of building rational model ranges of hydrodynamic torque transformers.The purpose of the study is to analyze the existing approaches to development of model ranges of hydrodynamic torque transformers and to search for criteria for development of a higher-quality calculation method.Methodology and research methods. The study was carried out by comparing the model ranges of hydrodynamic torque transformers in question produced by various manufacturers and defining the common parameters applied to classify models in a model range.Scientific novelty and results. As a result of the analysis of model ranges of hydrodynamic torque transformers and existing methods of development of model ranges of hydrodynamic torque transformers, classification of approaches to their development has been carried out. Recommendations were also given regarding the parameters to be considered when developing model ranges of hydrodynamic torque transformers.The practical significance consists in the systematization of information about the model ranges of hydrodynamic torque transformers of different manufacturers. It is shown that building model ranges of hydrodynamic torque transformers according to the known methods does not take into account correspondence of their key parameters with the characteristics of the range of internal combustion engines applied together therewith. The paper offers the approach, which takes this aspect into account.
