Influence of Groove Type on Friction Coefficient of Wet Friction Clutch Pair
Abstract
The shape of the groove in the friction plate of a wet friction clutch has an influence on the dynamic friction coefficient of the friction pair. Some suggestions are put forward for the selection of the groove type of brake pads. This study establishes a dynamic friction coefficient calculation model for clutch engagement process considering the asperity and lubricant bearing capacities of the centrifugal force of the oil film. The model is based on the Reynolds equation, average flow model, and Greenwood model. The friction coefficients of different groove shapes were measured using the SAE#2 testing machine. The measured results were compared with theoretical calculations to verify the accuracy of the theoretical model. Under the premise of satisfying the torque transmission condition of the helicopter, the groove type of the wet clutch friction plate should be waffling groove or double arc groove. In this study, some suggestions are put forward for the selection of the groove type of the friction plate of the wet clutch.
期刊介绍：
The International Journal of Automotive Technology has as its objective the publication and dissemination of original research in all fields of AUTOMOTIVE TECHNOLOGY, SCIENCE and ENGINEERING. It fosters thus the exchange of ideas among researchers in different parts of the world and also among researchers who emphasize different aspects of the foundations and applications of the field.
Standing as it does at the cross-roads of Physics, Chemistry, Mechanics, Engineering Design and Materials Sciences, AUTOMOTIVE TECHNOLOGY is experiencing considerable growth as a result of recent technological advances. The Journal, by providing an international medium of communication, is encouraging this growth and is encompassing all aspects of the field from thermal engineering, flow analysis, structural analysis, modal analysis, control, vehicular electronics, mechatronis, electro-mechanical engineering, optimum design methods, ITS, and recycling. Interest extends from the basic science to technology applications with analytical, experimental and numerical studies.
The emphasis is placed on contributions that appear to be of permanent interest to research workers and engineers in the field. If furthering knowledge in the area of principal concern of the Journal, papers of primary interest to the innovative disciplines of AUTOMOTIVE TECHNOLOGY, SCIENCE and ENGINEERING may be published. Papers that are merely illustrations of established principles and procedures, even though possibly containing new numerical or experimental data, will generally not be published.
When outstanding advances are made in existing areas or when new areas have been developed to a definitive stage, special review articles will be considered by the editors.
No length limitations for contributions are set, but only concisely written papers are published. Brief articles are considered on the basis of technical merit.
