High-Power Hydromechanical Transmissions: Patent-Informational and Computational Investigation. Part 3. Gearboxes with Four Degrees of Freedom and General Analysis
Abstract
This article finishes publication of results of high-power hydromechanical transmissions investigation. The first and the second parts were published in previous editions of journal. In this part gearboxes with four and more degrees of freedomareanalyzed with the use of methods of calculation from the first part and indicators of compactness and loading from the second part of the work. Allison, Caterpillar, Komatsu and General Motorshigh power transmissions are observed. The latest patented gearboxes of Zahnradfabrik, Hyundai, Jatco, Aisin AW and Volvo for trucks and passenger vehicles are presented. Relations between compactness, number of degrees of freedom, configuration and loading of gearboxes are shown. A task of obtaining a gearbox with minimal loading is formulated and an example of such gearbox is given. General conclusions on results of analyzing of gearboxes with three and four degrees of freedom and methods of investigation are presented.
