Product Code:SAE J641
Title:Hydrodynamic Drives Terminology
Issuing Committee:Automatic Transmission Transaxle Committee
Scope: Since the torque converter and fluid coupling have become commonly used components of automatic transmissions in industry, the SAE appointed a committee to standardize terminology, test procedure, data recording, design symbols, and so forth, in this field. The following committee recommendations will facilitate a clear understanding for engineering discussions, comparisons, and the preparation of technical papers.The recommended usages represent the predominant practice or the acceptable practice. Where agreement is not complete, alternates have been included for clarification.Example - Two systems of blade angle designations are described. Consequently when a blade angle is specified, the system should be designated.This SAE Recommended Practice deals only with the physical parts and dimensions and does not attempt to standardize the design considerations, such as the actual fluid flow angle resulting from the physical blade shape.
