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