Sažetak
In this paper, the methodology of establishing two-carrier planetary gear trains (PGT) equipped with a speed-changing system which contains breaks and clutches is considered. The reactive shaft is changed by means of breaks whereas the input and output shaft of the gear train are changed by clutches. Compound multi-speed planetary gear trains are obtained by a combination of two-carrier two-speed planetary gear trains controlled by only two breaks. The coding system of the two-speed planetary gear trains, which defines the connection between shafts of planetary gear sets and the shaft layout equipped with breaks, a driving and an operating machine is shown. It is established which variants of two-speed planetary gear trains are possible to combine by means of corresponding clutches in order to get two-variant or three-variant PGT. The methodology of choosing two-carrier PGT which are created by a combination of two or three two-speed variants within the frame of the same scheme is described as well as the example of finding an optimal three-speed PGT by means of the developed computer program 6-brz is shown.
