<p>PURPOSE:To dispense with double engagement changingover control while only two sets of planetary gear sets are used, and moreover the number of speed changing elements is lessened. CONSTITUTION:An input shaft 1N is provided with the first planetary gear set PG1, and the second planetary gear set PG2 is provided so as to be coaxial to an output shaft OUT. The first sun gear S1 is always connected with the input shaft 1N, and the first brake B1 which can fix the first pinion carrier PC1 to a case is provided. The first clutch C1 to connect the first pinion carrier PC1 with the first sun gear S1 is provided, and the first gear couple HG1 to connect the first internal gear R1 with the second sun gear S2 is provided. In addition, the second gear couple HG2 which can mutually connect the second pinion carrier PC2 and the input shaft 1N and the second clutch C2 are provided, and the second brake B2 to fix the second sun gear S2 to the case is provided, and the third clutch C3 which can connect the second sun gear S2 to the second pinion carrier PC2 is provided to always connect the second internal gear R2 with the output shaft OUT.</p> |
