Abstract

Relatively recent have occurred dual-clutch automated boxes, which promise a lot in the field and can be used successfully in cars and trains as well as in the aerospace industry. This paper wants not only to present such a gearbox but also to realize its dynamic synthesis, based on the engineering optimization of the mechanical efficiency achieved in each used speed gear. The presented method is original. In the paper are presented the original dynamic synthesis relations, based on the mechanical efficiency of the exchanger, determined separately for each of its speed gear used, for six forward and one on reverse. The applied method of calculation is based on a precise technology used to determine the mechanical efficiency of a gear, depending on the number of teeth of the two wheels in the gear, the angle of the pitch circle and the tilting angle of the wheel teeth in drive.
