SPEED MECHATRONIC VARIATOR Part I. CONCEPTUAL ASPECTS

Abstract

In the paper there are analyzed the main methods of synthesis for a technical product of type: speed variator with continuous adjustment, characterized through big values of the speed transmission ratio and through high power. Based on this analysis, it is proposed a conceptual solution for such a variator, under the conditions of obtaining a certain range of adjustment and high efficiencies. The proposed solution contains a symmetrical differential, an electrical motor (equipped with a control system for the adequate change of the mechanical characteristic), an electrical generator (with a fixed mechanical characteristic) and an output shaft, characterized by high values of the moment and through adjusted speed. The operating principle of the variator is explicated in this first paper.
