Download or read book Minimizing of Automotive Transmission Rattle Noise by Means of Gear Oils written by Axel Baumann and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Caused by downsizing of combustion engines, the torque fluctuation at the crankshaft induces torsional vibrations in the powertrain. Manual transmissions and dual clutch transmissions are particularly sensitive to gear-rattle noise. Gear-rattle noise arises from oscillations of loose parts with clearance, e.g. idler gears, synchronizer rings and gearshift sleeves. The aim of this research is the formulation of a gear oil for the application in a manual transmission to minimize gear rattling noise. Acoustic measurements on a gear-rattle noise test bench verify the noise reduction of the developed gear oils with commonly used low oil viscosity. An analysis of the transmission error proves that gear tooth impacts during rattling lead to elastic deformation of the meshing gear pairs. The main source for the intensity of gear-rattle noise is the additional presence of meshing impacts at the beginning of each gear pair meshing. Gear-rattle noise reduction can be achieved by avoiding meshing impacts, e.g. by minimizing the traction coefficient of the gear oil. About the author Dr. Axel Baumann is an engineer & top business expert for technology in vehicle and mechanical engineering. He has proven leadership and management skills from his many years of work as a department and project manager and from his 4 years as a university lecturer and scientist. His studies and doctorate at the University of Stuttgart in the field of machine components dealt with powertrain technology.
